« Previous EntriesForbes: The LED Illumination Revolution
Wednesday, February 27th, 2008Forbes magazine lays out all the reasons why LED lighting may be here sooner than you think. While the current push is on for Compact Flourescent Lights (CFLs), the current state of LED lights provide much greater efficiency and durability, and don’t contain any mercury. While LEDs are now way too expensive for consumer use, [...]

Toyota unveils hot new hybrid sports car, the FT-HS
Tuesday, February 26th, 2008Pretty sharp looking, if you ask me. Some people are saying that some form of the FT-HS will become the new Toyota Celica, which is a car that I’ve always had a fondness for (although I’ve never owned one). Toyota, at the Melbourne International Motor Show, today unveiled its FT-HS concept car. The [...]

Moth eyes may hold key to more efficient solar cells
Saturday, February 23rd, 2008Physorg.com is reporting on a new process from Peng Jiang, an assistant professor at the University of Florida that looks to the structure of moth eyes for increased solar cell efficiency. Jiang method increases the amount of sunlight absorbed by reducing the amount of sunlight reflected. Jiang says that the current [...]

IBM measures the force needed to move individual atoms
Friday, February 22nd, 2008This isn’t specifically related to alternative energy, but I found it pretty cool. It potentially could have big ramifications for the nanotech field and might also lead to future semiconductors that use way less power than current chips. IBM researchers, in a press release, have announced that they are the first to measure the force it takes to move individual [...]

Solar Cell Directly Splits Water To Produce Recoverable Hydrogen
Wednesday, February 20th, 2008From Science Daily: While its only in the proof of concept stage, researchers at Penn State have developed a device that uses sunlight to split water and produce recoverable hydrogen. Right now its extremely inefficient, but the researcher team thinks they can get up to 10-15 percent efficiency. At higher efficiencies, it’s [...]

Utah to help property owners evaluate wind power
Sunday, February 17th, 2008Here’s what sounds like a good and useful thing that states can do to encourage alternative energy use. The Utah Geological Survey will lend wind-measuring anemometer towers to residents to help determine if their property can become a reliable source of wind power. Utah says that they will install either a [...]
