In 20 years, mankind will consume twice as much electricity as we do today. To meet that demand, 4,000,000 megawatts of new electrical generation will be built, at a total cost of over $4 trillion.
Providing all our energy needs from renewable sources will not be easy given the low power density of renewable sources. An impractical four million square kilometers of wind turbines would be required to meet future electrical requirements – an area half the size of the USA, and about 10 times as much land as would be consumed by efficient solar power facilities.
Experts, governments and utilities now agree that up to ¼ of the world’s future electrical needs can – and should - be met with solar power. Etalim Inc. is developing breakthrough solar power generation technology. The Etalim device is elegant, straightforward to manufacture, and inexpensive. Etalim’s technology aspires to generate electricity that is:
- 25% cheaper ($0.04 per generated kWh, or $0.65 per installed Watt) than any known or planned solar generation method – cheaper even than coal,
- 25% more efficient in converting sunlight to electricity, relative to any known solar technology,
- 25% less demanding of land and other resources
- Completely clean and emission-free,
- Produced elegantly, reliably and virtually maintenance-free for decades.
Etalim is developing a new type of solar dish system. Solar dish systems concentrate sunlight and convert it to electricity on the spot, thereby enabling higher efficiencies, which results in less mirror area and lower cost for the same amount of electricity. These dishes in massive farms can support large urban centers, or in smaller quantities address local or personal needs.
The Etalim solar system is comprised of a concentrating dish that focuses sunlight onto a Thermal Electric Generator (TEG). The TEG represents Etalim’s key innovation. The TEG is a patent-pending high-frequency hybrid Stirling/Thermo-acoustic device that converts heat into electricity. Etalim's TEG eliminates sliding or rotating seals for maintenance free life. This novel architecture also enables the use of high temperature ceramics, leading to greater electrical conversion efficiency. The Etalim design is simple, does not require expensive, rare or toxic materials and lends itself to volume manufacturing. These characteristics translate to low cost production and to sustainable advantages over competing products.
At Etalim, we are developing a solar dish system that takes solar energy in, and outputs clean renewable power for years. With this kind of solution, why burn coal?
