Any magnets with the same polarity repel each other and those of opposite polarities will attract each other. When the magnets are aligned strategically, they generate energy and go around in a spinning motion (the magnets slide down and push each other upwards). This motion is often referred to as Perpetual Motion and is said to generate electricity.

To understand how such magnetic generator should be built, I propose you to follow these ideas:

1. First you have to build the inner wheel of your generator. You need to fix a wheel capable of spinning, made of plastics or other non-conductive material, at a tilting angle.
2. Then you need to fix your bar magnets around the edge of this wheel. The magnets must be arranged in such a way that the opposite of each magnet will have the same polarity.
3. Next you need attach the outer ring (also made of a non-conductive material). The outer ring must be attached on the rim of the inner wheel.
4. All magnets of the inner ring must have fixed magnets with opposite polarity compared with the outer ring.
5. Now, it’s almost done. You need to spin the inner ring in such a way that when it reaches the furthermost point of the orbit, the magnets of the outer ring will oppose the magnets on the inner ring to continue the spinning motion.
6. As long as the inner ring keeps spinning, your system will generate electricity.

Unlike solar or wind generators, a magnetic generator will be equally effective but it will use only small bits of energy over time. Moreover, a magnetic motor could last for more than 200 years which means that you, your children and even your grandchildren could use the same car for exampleJ. Such magnetic generator can be efficiently used to power your home with almost zero costs on your side. Thinking that free energy generators will be the energy in the future, we might anticipate that all big energy companies will start implementing this technology. So, until they will do this, I think we could build such magnetic generators at home, in order to save our economies as much as we can.

(I have presented to you these six steps just to give you an idea of how a magnetic generator should be built – if you want to build it at home you need to use “MagniWork” guide)

With no viable alternative to gasoline oil in sight, the search for a more

Lithium-air batteries basically consist of a air cathode which supplies air (more exactly oxygen), a lithium anode and the electrolyte separating them. In theory, they can store equally as much energy as a tank of gasoline would, and with the oxygen as a unlimited cathode reactant, the capacity is only restricted by the Lithium anode, thus potentially surpassing the current lithium-ion batteries energy storage capacity by 5 to 10 times. Nonetheless, in order for it to come into fruition certain critical steps in technology need to be undertaken.

“The obstacles to Li-air batteries becoming a viable technology are formidable and will require innovations in materials science, chemistry and engineering,” said Argonne Director Eric Isaacs. The Argonne National Laboratory, from the Department of Energy(DOE), is one of the leading research center for batteries worldwide. The battery is considered to be a long-term technology, which will require time, collaboration between the different branches of science and also money, in order to overcome the main challenges of the product: life, costs, performance and safety.

And the interest in this technology doesn’t seem to be short of, as the DOE recently gave away $8.8 million to the lab, into building out three battery research facilities that will be used for battery development,  manufacturing and testing.

A

The results of the study are conclusive and definite: incandescent lights use 5 times the amount of energy, LED or compact fluorescent lightbulbs. The study also shows that the energy required in the manufacturing and distributing for all the lamp technologies amount to only 2 percent of the energy consumed in their lifetime.  Another fact worth mentioning is that LEDs and compact fluorescent lamps need only 20 percent the energy a incandescent light needs, to provide the same illumination. This looks like another battle won by the LEDs.

The study was conducted in conformity with an industry standard, specifically ISO 14040/44, and the results were accredited by three university professors from Germany and Denmark.

In the last days of the gasoline-powered vehicles, the competition for the car of the future is harsh and open for surprises. There is still no definitive winner, although the electric car has won some important “battles”. Yet other technologies await recognition and some attention from the public. For example, the pneumatic-propelled engine technology has taken some major steps towards the big stage.

The AirPod, the chariot-like three-wheel car that runs on compressed air, is the culmination of a father and son work. Guy and Cyril Ncgre , the CEO and R&D coordinator of MDI, a company Guy created, having in mind the protection of the environment. They plan to manufacture it early next year, at a “one vehicle per hour” tempo.

The vehicle has a weight of 220 kilograms and runs on 80 kilograms of air, compressed to 350 bars. The maximum velocity reaches 28 mph (45 km/h) and an estimated range of 137 miles (220 km), if driven in a urban area. The car doesn’t require for the driver to have a driving licence and is steered using a joystick.  There is room for 3-4 passengers, with two of them in the backseat, faced backwards. It takes only 3 minutes to re-compress the tank with air and the costs are also very low, only 0.5 euros  per 100 km. The car’s exhaust, which is very cold air, could also be somehow used to cool the passengers in the hot summers.  The costs of the car rise to about $9,000(€6000).

A big impulse to bring AirPod to life, came when the announcement from January, 2008,  by the mayor of Paris, Bertrand Delanoe, was made. The plan is called Autolib and involves buying 4000 electric cars, for the Parisian people to rent by the hour. The company  hopes to convince with they model, which is cleaner, has a longer range and is cheaper than the electric cars.

But there some black clouds have gathered around the company. And they come from IEEE Spectrum, which were addressed to inspect the car’s performances. As it turned out, the MDI company have kinda hyped the car’s actual potential. They question the car’s real range, which should only be a third of what the company claims, because, as they analysed, a great amount of energy is being wasted in the process of expanding the air before it is sent to the engine.

Other barriers constitute the laws of nature. According to some scientists the laws of thermodynamics make the use of compressed air as a power source very unreliable. Also, the AirPod’s 200-liter air tank should not be more potent than one liter of gasoline. The company counters saying they engine doesn’t need that much energy to run.

The contestants were supposed to design a house that is self-sustaining, meaning it should produce as much energy as it consumed and at the same time provide a pleasant look. Other areas of judgment were architecture, viability, engineering, lighting design, communication, hot water systems, temperature, appliances, home entertainment and total energy production. This year’s winners of Solar Decathlon, which was held at the National Mall in Washington, D.C. where firstly, the German team with a score of score 908.29 out of maximum 1,000  points. Second place went to the University of Illinois at Urbana-Champaign which scored 897.30 points and finally Team California took the  third place, amounting to 863.08 points.

The German team from Technische Universität Darmstadt, designed a two-story house in the shape of a cube, all covered with solar panels. They where the only team to win all the 150 points given in the “net metering” (the total energy production) category, being able to build a house that produced more energy than it consumed,even though it rained on 3 days. The energy surplus they managed to deliver was pumped to the electric company from the Washington area. The points they earned would later than prove to be decisive in winning the competition.

We all know how hot and how much heat the roads dissipate during summer times. We all have seen the hot road mirage on the highways, where the road seems soaked in a pool of water. Well, what if this heat and energy can, in some way be extracted and stored as electrical energy ? This was the idea that captivated Scott Brusaw’s imagination since childhood. Now, as a grown man,  after he acknowledged the dangers of global warming, he came up with the concept that enables him to use this, once lost, energy. After years of development, together with his wife, they introduced

The idea is to transform the current bitumen roads into giant solar panels, generating electrical energy. The solar road panels themselves, consist of three layers:

• Road Surface Layer – the upper most layer is made of glass, so that the sun rays can pass through it to reach the solar cell collectors below, but has the required strength to withhold the heavies loads available on the road today. Weather shouldn’t also be a problem to it.
• Electronics Layer – is the most important layer, the place where the solar cells are introduced. LED’s will also be placed to light the road from below. Ultra-capacitors will then store the extra energy collected. Each solar road panel incorporates a microprocessor, that deals with all the road functions, such as energy transportation, storage system etc. This intelligent system could also be programmed to heat themselves when snow or ice threatens the solar panels from collecting energy.

• Base Plate Layer – this layer is designed to transport the accumulated energy from the solar panels and deliver it to all who need it. Other wires, such as the phone line or the high-speed Internet connection cable could be seated here.

The idea has great potential and its seems they can start building their first prototype. The Department of Transport has recently financed the project with $100,000 to build a 12′ by 12′ solar panel.

His calculations show that three times as much electrical energy as the amount consumed 2003 in the U.S could be delivered by his invention, if the whole road system used the Solar Roadways concept. He estimates that with a solar panel efficiency of more then the current 15% (which future technologies should deliver) the U.S Solar Roadways alone, could provide the whole planet with electricity.

Surprisingly enough, the costs aren’t so high as expected. As a matter of fact, the Solar Roadway system would cost almost the same as the current petroleum-based system (the asphalt roads and the electricity plants that use fossil fuel for burning).

The invention of the solar cells, those devices that convert the energy of light into electrical energy,  was really a bliss to mankind. The first solar cells were created in 1954 by three American researchers, Gerald Pearson, Calvin Fuller and Daryl Chapin, out of very thin stripes of silicon capable of about six percent conversion efficiency. After more than 50 years, today’s highest solar cell conversion

Today we find them installed everywhere. From house rooftops, all the way to cellphones. They represent a important tool towards a more environmentally-friendly and energy efficient society. And with the sun as the main energy source, it’s practically a product for the ages, because it will never stop providing with energy(or just in about 5 billion years!).

The next place where these devices were fixed are the backpacks. Yes, you can now listen to your favorite music on your iPod or write your memoirs on a laptop even if becoming lost and you’re far away from home,maybe somewhere in the Sahara dessert. Provided, you are equipped with the latest voltaic backpacks, there are no worries anymore.

The company Voltaic Systems offers some of this bags. The bags have appropriate adaptors, so it will fit to any electronic device you want to recharge. Their most powerful one, the Generator, can produce 15 Watts of electrical power. That is enough to power  a standard laptop, after a day long exposure in the sun. The other, more smaller bags produce 4 Watts, more suitable for an iPod for example, providing a play time of over 3 hours, or for 1,5 hours of cellphone conversation,  after leaving the bag for only one hour in the sun. The product also comes with batteries, which means that any surplus of energy will be stored, for later use. Also included are the AC  travel charger or the car charger, if the opportunity comes along.

The car comes with some high EPA ratings: 35 miles per gallon(~56 km)  in the city and a gas mileage of 34 on highways.  Fueled with 20 gallons, the hybrid is able to drive an impressive 700 miles(~1127 km).

The Altima Hybrid deserved a place in the  AT-PZEV( Advanced Technology-Partial Zero Emissions Vehicle) class. It means that the car emits hardly measurable quantities of gas emission. That is 90% more environmentally-friendly then the average new car models.

This eco-car is powered by hybrid system, composed of a 2.5-liter four cylinder gasoline engine and 40 HP electric motor, which work very efficiently in tandem.  In order to cut the gas consumption as much as possible and have a low environmental impact, the car switches from gas to electric on low speeds, or shuts the gas motor off, when the car is breaking, thus recharging the battery using the momentum of the car, energy which otherwise goes to waste. When the car is stopped, the gas engine is shut off and the electric one kicks in, to spare the gas. The combined power of the system reaches 198 HP.

The on-board display and interior are also amazing. You can graphically see how the energy is transferred to the wheels, when the gas or the electric engine is functioning – you can practically follow the energy flow in real time.

The driver will definitely feel save in the car. The model is equipped with 6 air bags and has received 5 Stars from NHTSA – the National Highway Traffic Safety Administration and has reached a rating of 9,9 out of 10 regarding it’s security on the roads.

Of course, the car features some other accessories, such as blue-tooth, an in-built-navigation system, rear-view camera or a surround sound system, which could rise the price up to $35,000.

Together with the french automaker Renault, Nissan have set the EVs improvement and development as top priority, believing that environmentally-friendly electric cars are the thing of the future.  It is said they plan to build 100,000 electric cars in the next two years.

The new electric car will be powered by a 24 kW/h lithium-ion battery, placed in the front of the vehicle, which provides their own-made electric motor with energy. The engine is capable of producing 80 kW(107 HP), equal with 206 pound-feet of torque which can push the car to a maximum speed of 140 km/h (87 mph).  No information about the battery recharging time has been revealed by the company’s officials yet.

The main reason why electric cars still haven’t taken the “big step” and go globally commercial is the battery. The first electric car models from Nissan needed 26 minutes, provided with 440 volt of electricity, to charge the battery 80 percent. That is still a long time, if we consider today’s refueling time at petrol stations. But this is where Nissan promised  to bring improvement with it’s new electric car: the driver will be announced in real-time by the on-board computer when and where to charge the battery.  The system is called “EV-IT” and should work perfectly with the  navigation system of the car. The option of  receiving messages when the battery is fully charged is also available.

The company didn’t share the information about the new electric car’s price, but there is no expectation that it will be cheap.  Although it will take some years until we will see electric cars cruising on the streets the hopes are high for this technology. There is definitely a need for a petroleum alternative, because of the harm for the environment and its availability. Even so, the reserves will last for only40 more years.

Researchers from the Korea Advanced Institute of Science and Technology (KAIST) made a impressive breakthrough in the  improvement of OLED technology. The new research brought to light an incredible 75% cutin energy consumption, an achievement that premises to, one day, make this products available to us, all.In the process, they discovered the surface plasmon method, in which silver nanoparticles are thermally placed in a high vacuum on a cathod, resulting in a 1.75 increased photoluminescence and a two-fold light intensity expansion.

There is no doubt, that this discovery will boost the coming of this energy efficient OLEDs in future gadgets, but let us hope that the day when we will be able to read news from flexible OLEDs screens is not so far away…

Without making a separate race for this initiative, the teams joined the rally for the “greenest” car by entering the 1,000-mile Petit Le Mans sports car endurance race held annually at Road Atlanta in Braselton, Georgia, USA.  At the end of the race, the cars got marks using a model called GREET which takes into account the greenhouse gas emissions, total energy consumption, fossil fuel consumption as well as petroleum-equivalent fuel cost among other criteria, such as vehicle mass and average velocity. The standings came a bit different as those from the ovarall race: a Chevrolet Corvette car that finished fourth in the overall ranking won first place in the class “Green Challenge’s Grand Touring”.

The success of the event was visible because, as of this year,  the green races will be stretched to take part in the whole session of the the American Le Mans Series in a new performance called Michelin Green X Challenge. So at the end of each season,  the team with the best results in the “environmentally friendly” category, will be crowned as the “greenest” car of the season.

After six years of work  and involving 70 people, the HB-SIA is impressive in all the chapters. With a wingspan of 63,4 meters, comparable with that of a Boeing 747-400 or a Airbus A340, and a weight of only 1,600 kg (compared to the  66 tons of the 747-400) this airplane is really one of a kind. The necessary energy is provided by the sun rays trough the numerous  solar cells (more then 12,000 monocrystalline silicon cells, most of them on the wings).  The aircraft, build out of carbon fiber,  is propelled by four 7,4 kW electric engines, can reach a maximum speed of 70 km/h and can fly up to  8500 meters high. The engineers were forced to work more on the aerodynamics and energy efficiency in order to counterbalance the weight(400 kg) of the “old” lithium polymer batteries, which are to be used during the night flight.

The purpose of this prototype is to show the possibility of building an airplane capable of doing a complete day-night cycle flight using only the sun as a energy source.  It is expected to do a test flight later this year.  The success of the prototype will make its mark on the second aircraft, the HB-SIB, planned for 2012, which will attempt to fly around the globe in five stages, each one taking a few days.

The project is directing a clear message towards a more renewable energy based future and is promoting the use of an fossil fuel alternative. It represents the hope of someday eliminating the oil dependency and turning towards environmental-friendly products.

In the study, the Earth was divided into surfaces of 3,300 square kilometers (1,274 square miles) to be able to appreciate the wind power capability, while monitoring wind velocity every six hours. Excluded from the calculations were “areas classified as forested, areas occupied by permanent snow or ice, areas covered by water, and areas identified as either developed or urban,” so the study. In the rest of the land, wind turbines capable of  2.5 megawatt, are to occupy space, also 3.6 megawatt wind turbines in water, as far as 50 nautical miles beyond the coastline and in oceans with less then 200 meter depths.

Using the above conditions, the results from the study showed that the energy extracted from the wind is forty times greater than the planet’s demand for electricity today and all energy necessities combined,  five times.

The researchers agreed that, to the question “How to easily cut the carbon dioxide emissions at a global scale ?” , wind power is the answer.  In doing so, the big carbon emittors such as China, United States or Russia would make the environment a great joy if they seriously turned to this of endless source of energy.

The company has already started installing Vector lightning systems at 12 sites, such as Osuna Business Park ,Bosque School and DKD Electric. Besides greatly

reducing electricity consumption, the application is compatible with most existing infrastructure of wiring and light poles. Also, as a environmental action,Visible Light Solar will see that the old  HID bulbs containing mercury or xenon will get recycled by National Metals.

Visible Light Solar achieved this improvements by integrating LED lighting devices with solar power technology(Direct Distributive Power Generation). That leads to an efficiency increment of over 85%  than the out-dated HID technology through the  energy efficient LED components corroborated with  solar power technologies. The culmination of these two technologies resulted in the creation of a power management infrastructure, the Self Powered Device Interface (SPDI),  a high-tech machinery able to control voltage fluctuations and  performing a intelligent  switch between solar battery and grid power. With the use of the LED’s the company came up with a more reliable source of illumination, the LED’s  proving more durable, lasting up to 100.000 hours and coping better with difficult weather conditions.

The flashlight consists of 3 LED lights and requires  no conventional batteries but instead is equipped with a new technology called Flashpoint Power, which uses ultracapacitor energy storage systems to benefit the recharging process.

Technically it means that the “Light for Life” is operable after just 90 seconds of recharging.  When it comes to illumination, the flashlight can provide 90 lumens for 90 minutes for one charge. Also it has three modes: bright (reaching at it heights 270 lumens), standard (90 lumens), and strobe. If we consider that a 60 watt incandescent bulb is rated at approximately 800 lumens while a 40 watt bulb is rated at 400 lumens and a small standard 4-watt night light bulb delivers about 20 lumens, the LEDs, with the help of the latest improvements in technology prove to be a reliable  alternative to conventional illumination systems.

According to the providing company, the  LEDs have a life-time of 50,000 hours  and don’t need replacement, also the flashlight is guaranteed to work even after 10 years of use under typical conditions. In case of an electricity failure, you can always use the 12V DC automotive charger and, which comes together with the product, and use you car to recharge it. If it has a disadvantage, then it is the price: $169.99.

The Project will use the available technologies that have already been proven to work efficiently.

Concentrating Solar Thermal Power is the main technology to be used. It consists of the use of mirrors to concentrate the sun’s rays  to create heat which, in turn produces steam to finally, after driving turbines and generators, produces electricity.

But just like with The Sahara Forest Project, the concept still needs to surpass the political misunderstanding in order the get it started. It is also feared that building it in political unstable countries will create the same dependence as with oil today.  Still positive signals come from involved investors and countries representatives, who push with power from behind to make this Solar Mega-Project a near future reality. 

In regard to the latest developments in solar technologies , the North of Africa seems a viable source for Europe’s increasing demands for energy.  The challenge is to get the level of alternative, renewable energy sources to 20 percent by 2020.  With an investment of 50 billion euros for the next 10 years, explained Dr. Patt, the project will reveal its attractiveness and efficiency to the private investors.

The plan also evolves building wind farms along the North African coastline, which is very effective because of the powerful winds generated by the hot dessert soil during the summers from Africa.   The only problem that still need to be  overcome is the challenge of overcoming political difficulties, for example the people who argue with the installation of  transmission cables near their homes.

Another great design is The Sahara Forest Project (showed in the picture above). It involves turning a part of the Sahara dessert into a source of water, energy and food. The main components are the Concentrated solar powers and Seawater Greenhouses. The Seawater Greenshouses will be responsible for converting sea water into clean water using the sunlight(water runs trough in-wall cavities then air is pumped trough them and get condensed to create clean, healthy water). The Concentrated solar power is a technology that  uses thousands of mirrors to focus the sun rays upon a water boiler reaching temperatures of over  1,000 degrees Fahrenheit. The  steam that is generated through the process  drives a turbine to produce energy.

Which of this projects will finally find its success is for time to tell.

Tap water is used lesser and lesser for drinking purposes which has partly to do with the fact that some countries introduced excessive levels of Fluoride in water (for ex. in the US, England etc.) to supposedly prevent tooth decay, which in fact has been proven to be toxic and the cause of undesirable cosmetic effects such as staining of teeth (Activated alumina can be used as a good fluoride adsorbent).That is why more and more people decide to install  a water purification system in their homes.
Methods for clearing water were known and used by people since ancient times, as for example, distillation,through which 99.9% pure water can be obtained, or boiling, to inactivate or kill micro-organisms.
This easy techniques surely provide to a curtain degree clean and healthy water but some of the bacteria and
other organisms still survive this harsh treatments to finally end up in our bodies. Cryptosporidium , which is a small organism found in man and many other animals is one example. It can cause a disease called cryptosporidiosis, which is a diarrhoeal illness usually lasting about two weeks. Water that has not been suitably filtered can contain numbers of Cryptosporidium oocysts shown to cause illness.

Best Water Purification Methods

Here are the different methods of water filtration one would consider:

1. Distillation – probably the oldest but at the same time the most inefficient method – Removes a great deal of

harmful micro-organisms and pathogens but requires large amounts of energy and water to operate, is expensive and above all, some contaminants still manage to pass into the condensed substance.
One product that uses this method is the Compact General Purpose Still.

2. Carbon Absorption – a common method used nowadays because it is capable of removing bad tastes and odors, including chlorine but fails to do its job when it comes to total dissolved solids or heavy metals. There are two types of carbon filter systems: granular activated carbon and solid block carbon. The systems provide a long life functionality. You might find this product interesting. Some of it’s features include removal of up to 95% of VOCs, TOCs, chlorine, sediment and filtration down to 1 micron.

3. Ion Exchange – this water purification technology uses sphere-shaped resin materials to cleanse the ions in water. A differentiation between softening and deionization systems is made. In the method of softening, water hardness is being reduces before, normaly, a reverse osmosis processing takes place, whereas deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Deionization systems effectively remove ions, but on the other hand fail to properly remove most organics or microorganisms. They also can stimulate bacterial culture growth and prove to be quite expensive on a long-term usage. Here we present the Maxxima RO & Deionization System – 50 gpd, which uses the combination of solid block carbon pre-filter
and a high grade mixed bed deionization resin filter for a maximizing water purification efficiency.

4.  Microporous Basic Filtration – exists in three different types: depth, screen and surface, but usually all used
into one system. Starting from the most abrasive one, the depth filter, going down to the surface filters which finally removes 99.99%
of remaining solids, the filters integrated in those  systems are usually easy to use but are not regenerable and will not filter out chemicals, inorganics or pyrogens.
5. Ultrafiltration – uses a molecular sieve membrane to purify water. It is regenerable, has the highest water quality/ energy consumption ratio but will not
remove dissolved inorganic materials. The 10″ UF Membrane Filter Cartridge is such a product. The filter has a life of 3 years and removes particles larger then .01 microns.

6. Reverse Osmosis – the most cheap method to be yet discovered – is efficient at removing 90% to 99% of all contamination and most leading water bottling plants use
this technology with success. One of the disadvantages is its slow flow rate, that is why large containers are recommended to compensate it. Reverse osmosis is highly effective in eliminating asbestos, lead, turbidity and other toxic heavy metals, such as radium, and so being very efficient in purifying tap water. A decent product can be obtained here.

Most of the time this technologies will not be used individually in a water purification system but rather in combination. So, for example reverse osmosis works best with activated carbon filtration, being complementary processes and combining them will result in the most effective treatment against impurities in water. A good drinking water purifier has a price between $400-500. While bottled water may be an improvement over chlorine-fluorided  tap water, any well-balanced and effective system would be preferable over bottled water, which is clearly unreliable and expensive.

The new bus, measuring 18 meters in length, is powered by a large 19.4 kWh lithium-ion battery mounted on the roof  which can generate  totally up to 320KW.  The highly acclaimed hybrid (Winner of the DERKA Environment Award) is expected to be seen in European cities in the early months of 2010, when deliveries start.

Here you can find: How to Build a Magnetic Generator at Home. “To understand how such magnetic generator should be built, I propose you to follow these ideas:

1. First you have to build the inner wheel of your generator. You need to fix a wheel capable of spinning, made of plastics or other non-conductive material, at a tilting angle.
2. Then you need to fix your bar magnets around the edge of this wheel. The magnets must be arranged in such a way that the opposite of each magnet will have the same polarity.
3. Next you need attach the outer ring (also made of a non-conductive material). The outer ring must be attached on the rim of the inner wheel.
4. All magnets of the inner ring must have fixed magnets with opposite polarity compared with the outer ring.
5. Now, it’s almost done. You need to spin the inner ring in such a way that when it reaches the furthermost point of the orbit, the magnets of the outer ring will oppose the magnets on the inner ring to continue the spinning motion.
6. As long as the inner ring keeps spinning, your system will generate electricity.”
