The DOE has this site devoted to SSL technology and even an “L Prize” for innovation and breakthroughs in SSL.
Ever since I purchased a Toyota Prius and a Neuton rechargeable lawnmower, I’ve been both delighted and stunned with the compromises one has to make today to be more energy efficient: the Prius averages 47mpg but is less substantial (and luxurious) than what I’m used to in a car and the Neuton batteries (lead acid’s) and its engine is inefficient enough that I have to cut my lawn every five days or the mower bogs down.
