Not all countries have their own carbon-fuel sources to rely on, but some European countries are finding ways to become less reliant on importing oil and gas by tapping into their own renewable resources. Portugal is investing in wind and solar energies at a rapid rate and has even become an energy exporter. [...]Current solar technologies are split between using the light or heat from the sun’s rays to produce electricity. Now, Stanford has developed a device that can use both, boost efficiency by 200%, and cost less than oil.
Named “photon enhanced thermionic emission,” PETE harvests more energy than photovoltaic and thermal conversion technologies. Nick Melosh, assistant professor [...]
When We buy laptop battery on the market, the battery manufactures also claimed that their laptop battery life is 12 -15 month (300-500 recharge cycles). But after used 10 month our battery failed.

Founder of A123 Systems starts a new company to commercialize the technology.
As another reminder of the need to reconstruct America’s power grid in order to move forward with renewable energy sources, wind surges in Oregon are forcing grid managers to shut off the wind farms. Storms can cause production to spike so much that the power lines just can’t transport it all out fast enough. When [...]
Most of us use lithium-ion battery in laptop cell phones and iPods. As the developing personal laptop and mobile we will use it more frequently. In the recent 20 years the lithium-ion laptop battery is the best rechargeable battery compare to lead-acid and Li-polymer battery. Now it will be the power supply of the [...]
