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.

“The Sustainer”-First Mobile Biodiesel Generator
Solar energy, wind energy and a little ingenuity have made possible the realization of this complex system that produces biodiesel fuel.These technologies combined have resulted in a complex system,a not-polluting system,very efficient and with 0 exhaustible energy consumption.This type of system is very useful in poorer areas, like some places in Africa, where only 5-20% of the population has access to electric grid.Biodiesel professionals Solarix came with a new, complex, perfect solution for this problem.Future Cars Powered by Indian CottonSeed Biofuel
MyGreenTreasure contains many posts about hybrid cars, a wide variety of biofuels, cars that run with water, juice, beer….A recent study made by researchers from India has shown that future cars could be powered by cottonseed oil.Cotton is found in abundance in India, so researchers took this advantage, using cotton oil as a fuel.This biofuel proved to be very effective reaching close to diesel engine performance.“The researchers conducted experiments on a single-cylinder compression ignition diesel engine, which when fueled by cottonseed oil performed similar to a petroleum diesel fueled engine. The engine operating on the specific blended fuel actually showed improved emissions compared to the other fuels and fuel blends tested. The findings get even more promising as cottonseed oil is a comparatively low-cost source of bio-fuel as the cottonseed oil is only extracted from the seeds of cotton plants after cotton has been removed for other purposes. ” – www.ecofriend.org
5 Times More Effective Bi-Metallic Catalyst
Researchers from Washington University, lead by Younan Xia, Professor of Biomedical Engineering, has developed a bimetallic catalyst that is almost five times more efficient than other commercial catalysts.This type of catalysts could enable some cheaper fuel cell technology.The operation principle of this technology is based on the use of platinum and palladium and also using nanotechnology.
“Catalyst is said to be comprised of platinum and palladium that supports dendritic platinum branches, or arms, that are fixed on the nanostructure, consisting of a nine nanometer core and seven nanometer platinum arms. Due to this very reason, it can reduce precursor compound to palladium and platinum with L-ascorbic acid, commonly known as Vitamin C. Further, the high surface area of catalyst makes it suitable not only for fuel cell, but for many other applications. Researchers claim that this technique is two to five times more effective than commercial catalysts. According to the Department of Energy, reduction in the amount of platinum catalyst, that is considered one of the most expensive, can bring down the cost of fuel cell. Further, researchers are experimenting with other noble materials like such as gold that can be added to bimetallic catalysts to convert them into trimetalic. ” – www.ecofriend.org
What Actually Biofuels Are?
The mankind has used biomass fuels for heating and cooking since the discovery of fire.Biofuels can appeared as solid, liquid, or gas fuel.Liquid biofuels have been used since the early days of the car industry.By burning biofuels in a furnace, steam is produced which can drive turbines to drive an electric generator.
The discovery and use of fossil fuels like coal, gas and oil, have dramatically reduced the amount of biomass fuel used in the developed world for transport, heat and power.However, biofuels are axpanding recently in all over the world as providing an alternative to imported oil, because they reduce greenhouse gas emissions and increase energy security by providing an alternative to fossil fuels as in automotive transport and in gas turbine.As energy source in developed countries biofuel contribute about 15% of world’s energy requirements.
Biofuels can be produced from any carbon source that can be replenished rapidly as vegetable matter produced by agriculture and forests or from waste materials obtained from industry, commerce and residential homes, including agricultural waste as sugar cane, straw and chicken litter.Biomass is material derived from recently living organisms.It includes plants, animals, and their byproducts.Garden waste and corp residuel are all sources of biomass.By allowing fermentation in landfill sites or in special anaerobic tanks is also possible to produce methane rich gas to be used in gas turbines.
Biofuels are a renewable energy source based on the carbon cycle.Agricultural products specifically grown for biofuel production include corn and soybeans, wheat, sugar beet, sugar cane and palm oil.Biodegradable outputs from industry, agriculture, forestry and households can be used for biofuel production.
Biofuels and other forms of renewable energy aim to be carbon neutral.Therefore, the carbon released during the use of the fuel, through burning to power transport or generate electrical energy is reabsorbed and balanced by the carbon absorbed by new plant growth.Carbon neutral fuels lead to no net increase in atmospheric CO2 which means that global warming does not increase by this process.
Using waste biomass to produce energy can reduce the use of fossil fuels.Simultaneously reduce greenhouse gas emission and reduce pollution.In industrialized countries, biofuels are producing up 5% of electrical energy requirements.
5% More Efficient Biofuel Mixed with Polystyrene
“Dissolving polystyrene in biodiesel doesn’t eliminate the problem of harmful emissions, however. The scientists found that adding polystyrene increases the fuel’s emissions of carbon monoxide, soot, and nitrous oxides, which don’t burn completely in the engine. But the researchers hope to improve the engine’s fuel injection system to achieve a more complete burn with fewer emissions. If they can reduce the emissions, they hope that the technology could offer economic and environmental advantages for power generation.” – www.physorg.com
Regenerative Charging Stations for Electric Vehicles
The stationary charger has more power and efficiency, but it reduces the vehicle independency.The requirements for a stationary charger are:the output voltage situated between 60 and 200 V and the current intensity from 20 to 200 Amps.
The charging stations require an infrastructure connected to existing electric supplying networks.This infrastructure must have some characteristics:
- The type of material to be used for terminals, protection, signalisation;
- The localisation of the charging plug;
- The connection between vehicle and clamps;
- The security related to electrotechnical installation.
The inductive charging eliminates the problem of wiring the vehicle to the charger (wear and crrosion, influence of water, ice, oil and dirt, vandalism).The inductive charger operates on the principle of a transformer.The primary windings are vertically located on the wall or horizontally, on the vehicle’s board, together with the actual charger.Charging process consists of driving the vehicle close to the primary windings (the clereance of 5 cm, between primary and secondary windings, is sufficient for an inductive coupling between both windings).
Regenerative energy supply is required to protect the environment in the transport sector.The wind and the sun are significant energy sources at the moment.Wind installations are generally limites to a hundred kilowatts.A solar station can be up to 1,5 kW.The cost of a recharging station is to high at this moment, but the installation is expected to be the future potential reimplacement of the conventional recharging stations supplied by the electric network distribution.
Air Car VS Car That Runs With Water
The first car that used compressed air to make the pistons move was named “Air Car” and was released 2 years ago, by a builder of India.This car powered by compressed air, was not producing CO2 emissions.But to produce the compressed air was needed fossil fuels combustion(which means that there is still a small loss).Anyway,CO2 emissions were lower than a diesel engine.
Then appears something that in my opinion is even more avantageous.The car that runs with water.This thing was possible by separating the elements of water (H20) in gas HHO.Watch the movie below to understand how it works:
Now,what do you think?Which is most convenient car for you?The “Air Car” or the “Water Car“?
First Electric Car Charging Station
Nowadays we see that electric cars number is clearly growing,because this type of vehicles offers some important advantages, and people buy them without any delay.
We all know that the operation principle of these vehicles is based on batteries!These batteries are built with advanced technology, and are very efficient (have a high capacity of energy storage).Even so, sometimes these batteries should be charged for operate at normal parameters.
For this reason people are starting to build power stations for those hybrid, electric vehicles.Some days ago in Frankfurt, Germany was inaugurated a building of this kind,which is actually, The First Electric Car Charging Station from Germany(a loading station for electric cars).
This station is equipped with solar panels which distributes electricity for charging electric cars,small electric vehicles,scooters or other devices used on urban movement.This station was built in one of the crowded places from Frankfurt, in order to be available to anyone who passes and needs electricity for his electric vehicle.
Projects like this one will appear in a growing number becouse the electric vehicle production is also in growing number.
