These technologies are simple and innovative and will revolutionize the worlds energy supply. In this article, you will find some of the technologies that will end the World’s energy crisis.
Here are some examples to end World’s energy crisis.
The Windbelt technology came to be in 2004 when it’s creator Shawn Frayne too a trip to Haiti. At the time the local people were lighting their homes with kerosene lamps. Shawn realized that LED lighting powered by small wind turbines might better be able to light their homes and schools. The problem is that traditional wind turbines are inefficient at that scale, and so Shawn had to rethink wind power generation. What he came up with is a remarkable solution to small scale wind generation and the world’s first turbine free wind generator.
A thin, taught membrane vibrates in the wind in a process called aeroelastic flutter. This is a similar process to that which brought down the Tacoma Narrows Bridge in 1940. Small magnets at the belts edges move up and down with the membrane inside a simple copper coil to produce power. This technology is up to 10x as efficient as the most advanced micro turbine technologies of the same scale.
eThese technologies have already been implemented in Haiti and other developing countries and have gartered great success. Shawn’s company Humdinger Wind Energy is beginning to create starter kits, available in mid-2008, that will enable schools, enthusiasts, and anyone who wants one, to experience the power of this ingenious technology.
Corn has been used for many years to produce ethanol, a fuel similar to gasoline, which we can use to power our cars or heat our homes. Although the energy found in ethanol is clean burning and easy to use, its production process has hindered its environmental benefits. For instance to grow the corn to be used in ethanol production takes a lot of farm land that could otherwise be used to grow food. Also the process to which the corn is transformed into ethanol has a very poor efficiency. This means that it takes a lot of energy input to make very little ethanol, and so the total energy gain is small.
To solve these problems researchers along with big business have been looking at using cellulose instead of corn as the raw materials to produce ethanol. Cellulose is in essence fiber, and is present in every plant material. Because cellulose is available in all plant materials, there is no need to grow it exclusively for fuel. Ethanol can be produced from agricultural wastes that would normally be burned or end up in a land fill. Also cellulose has a much higher production efficiency. This is because it contains a substance called lignin that is separated during processing and burned to provide energy for the rest of the process. Lignin burns clean and lowers production energy needs dramatically.
Experts say that as soon as 2050 up to 30% of America’s fuel needs could be fulfilled by cellulosic ethanol. This would be a huge step forward to creating a greener planet.
Nanosolar Solar Film
Solar cells are great. They are clean, powerful, and have the potential to become a viable energy solution. The problem is that they are very expensive. Tradition cells are priced at 3$/watt, when you compare this to coal power that is valued at under 1$/watt you soon realize why solar technologies haven’t taken off…..yet.
A company called Nanosolar is about to change all that. They have engineered a method that can produce cells at under 0.30$/watt. Cells that can produce power that is cheaper than coal power! One quickly begins to imagine houses roofed with photovoltaic shingles, and office buildings coated in solar cells that simply pull power right out of the air. Cells that could power not only buildings in North America but everywhere in the world simply because it is the most cost efficient option. These visions could, according to Nanosolar, become reality in the next few years.
The breakthrough came from a printing press style manufacturing process, in which the cells are printed onto a flexible foil backing. The cells are then cut to size and applied to whatever you want. The new manufacturing technology is revolutionizing the way people conceive solar cells, changing their view from fragile and inefficient, to an industrial and reliable piece in the world’s energy solution
