Chizhevsky Chandelier Harvests Static Electricity from Air
Lately, researchers have found plenty of ways to produce electricity, using different technologies. It turned out that one of the most effective ways to produce electricity is to use renewable energy sources. So far we have discussed on MyGreenTreasure about several ways to produce electricity (using solar energy, wind energy, kinetic energy, etc.) but today I will present to you a new and revolutionary device, capable to produce static electricity from air.
IceBank – Storing Wind Energy As Ice
People are always searching for more efficient and economical solutions, always trying to keep things simple but also with a thought on energy costs. From an early time, man used ice to keep their food cooled. The ice was collected at so called “ice harvesting” sites and was the only way to refrigerate food, until the discovery of electricity.
Solar Roadways Could Power The Entire World
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 Solar Roadways, a company designed for a fully digitized roads, that could ,theoretically, someday power the entire world.
The Fastest-Growing Wind Power Market in the World
U.S. Department of Energy recently announced that wind power market has grown very fast in the last 4 years. The use of wind power increased by 60% in United States in 2008 which means that Americans invested $16 billion in wind projects. “At this pace, wind is on a path to becoming a significant contributor to the U.S. power mix…” Ryan Wiser from Berkeley Lab said. The electricity produced from wind energy currently represent 2% of the whole energy in U.S. This thing has an explanation: the need to reduce the cost of electricity production and electricity consumption has led to intense use of alternative energy sources.
No More Batteries – Eco-Friendly Dynamo/Solar Flashlight
If you plan to go on a trip or just hitch-hike and you get angry every time you think about taking the big, heavy flashlight to help you in the dark, this is good news for you. You no longer have to carry batteries in your backpack, because there is a “easier” solution to that.

Nowadays, solar energy is the most important alternative energy source on the planet. Solar centrals will be the main electricity suppliers in the near future. The perfect areas, where these solar centrals would work at maximum capacity are deserts. In deserts the intensity of solar radiation during the day is very high and solar systems would reach maximum efficiency.
$1,5 Million to Replace Old Military Batteries with Kinetic Generators
Effectiveness of a soldier, or a group of soldiers depends on how they are trained and how quickly they act in a certain situation. The reaction speed in a mission depends on physical condition and also depends on the military equipment weight.
Solar Forest Could Shelter and Recharge Your Electric Vehicle
The pictures of this post may be somewhat scary…trees are replaced with these “green giants” which look like trees.The ideea of this project is not bad, because these solar trees can make two good things at the same time: you can keep your EV cool under the trees shade and this “solar forest” can produce electricity for your EV.
540 MW Shetland Islands Wind Farm Could be Closed due to Disappearance of Local Bird Populations
Alternative Energy Sources represent the energetic future of our planet.People realized this, so they try to create more plants, to produce electricity from the sun or wind.Few months ago was opened 540 MW wind farm in the Shetland Islands but now it faces several problems that could close it.
Mint Energy Rechargeable Battery-Just Shake it for Full Energy
One of the main problems that we encounter on our gadgets is the short life of batteries.New developed batteries can work a long period, but what happens when, after this long period, the battery remain without electricity and you are located somewhere in nature, at a picnic or a walk?What you will do if you remain without electricity in your portable device?
USB phone charger using solar cells
Solar powering has gone pretty popular lately. In the picture above is 4-port USB depicted, that is said to also be able to charge mobile phone batteries. The hub is able to recharge its internal battery(with a capacity of 700mAh) from a computer USB port, but has also the ability, using its solar cell to power different devices through the USB port from its battery.
The Profitability of renewable Energy and Resources
An immediate and comprehensive transition to solar energy must talke priority over all other economic considerations.Any further delay will cost society more than it would to make the transition.The quicker and more comprehensively fossil energy and resources can be supplanted by their solar counterparts, the greater the cost saving to society and the less the strain on government budgets threatened by ever higher clean-up costs in the wake of fossil-fuel-induced catastrophe, be it storm od flood damage or regional wars over energy, the growing cost of waste disposal or the cost of maintaining an ever more bloated environmental protection bureaucracy.

The Higher Productivity of Biological Materials
The long road from extraction of oil, coal or gas, through refining and complex industrial processes to finished chemical feedstocks is matched in the case of solar resources by planting, harvesting, storage, cleaning, drying, separation andtransport.In many cases, transport costs can be held to a minimum by growing the materials near the production plant.
The only disadvantage as far as productivity is concerned is the considerably greater need for personnel, although this also represents a significant social benefit.Giuliano Grassi has calculated that, for each terawatt of energy, natural gas requires 250 employees, crude oil 260, coal 270 and nuclear power 70, whereas producing solid fuels from crops requires 1145 employees and 1000 employees in the case of woodlands.The greater labour input probably also applies to the use of solar materials in the manufacture of chemical products in place of the equivalent fossil feedstocks.

Output Amplification Devices for PV Installations
Industries producing alternative energy are evolving more and more, so solar systems launched on the markets are more efficienct and cheaper than systems used until now.Recently SolarEdge and BP Solar announced that they will reduce solar energy production costs by creating smart devices able to increase solar panels output.
This type of devices will appear in the near future more and more because inventiveness is the key to success in this field.Better than manufacturing other cheaper solar panels to reduce costs,researchers will attach amplification and monitoring devices on existing panels.
“The company states that losses due to problems such as shading, dust and a problem in any one panel in an array accounts to a total power reduction of as much as 20%. While solar companies have not succeeded in reducing the cost of panels by much, reducing these losses seems the need of the hour. The team is expected to soon test new products that should help reduce the cost of solar energy by making the panels more efficient. ” – www.ecofriend.org

Diamonds Used to Produce Solar Electricity
When I first read the title of this article I said: This is not possible! How to build a photovoltaic system with diamonds? It is not too expensive? Not require advanced technology too? And then I found out that Dr. Neil Fox from the University of Bristol’s School of Chemistry using thermionic energy converters (TECs), managed to create an efficient solar system (equipped with some parabolic dishes), able to generate a large amount of electricity (multi-megawatts).“The plan is to make use of devices called thermionic energy converters (TECs), which carry special electrodes using nano-particles of industrial diamond powered, which isn’t that expensive and is readily available as well. TECs are commonly used in spacecrafts where they require temperature well above 1,500˚C to produce sufficient electricity to power the craft.” - www.ecofriend.org
How to Check the Solar Radiation for Your Solar Panel
The Pyranometers are mechatronic devices suitable for measurement of solar irradiance on plane surfaces.ISO already stablished performance specifications for the pyranometers.These devices incorporate thermocouple-sensing elements that are imprinted on a thick film substrate.At his turn, this substrate is housed under Schott glass domes.The output signal cording to the specific design lies in the range of mV, which is directly proportional to the incoming radiance.
Pyranometers are a class of instruments used for measuring energy fluxes in the solar spectrum.These instruments are configured to measure what is referred to as global solar radiation, direct plus diffuse(scattered) solar radiation incidence on a horizontal surface.The sensing element of the typical pyranometers is protected by the clear glass dome that together protects the sensing element, and functions as filter and prevents the entry of energy outside the solar spectrum.The glass domes used on typical pyranometers are transparent to wavelengths in the range of 0,28 to 2,8 microns.Filters can be used instead of the clear glass dome to measure radiation in different spectral intervals.
