I currently drive a 2003 Prius, still using its original batteries... when I drive a car, that is. Regrettably, there's no public transportation between my workplace and home. But tonight I'll be headed home on my new Currie EZip bike with electric assist for the steep hills we have around here. So... the title of the thread was "electric vehicles." Does my bike count?

I keep hoping someone will invent the artificial chloroplast, and use sunlight to separate oxygen and hydrogen from water.
Nuclear waste concerns me. The vitrification method sounds good, but how do we leave a warning note guaranteed to still be understandable in 10,000 years, or even 500 years?
I'd feel better if we could get fusion plants working. But really, any energy production has an impact on the planet, by raising temperatures. I can't help thinking that improving efficiency (including conservation) is a critical part of our overall strategy.
