And history repeats itself
Nah really... thats like the 100th car which can use water as fuel. Its the same shit over n over again. Oh yea and they were all patented n stuff... as if that means anything. If someone would actually manage to do something like that it would be 24/7 in the media... for months to come.
One should focus on the stuff, which actually works. Like there will be soon way cheaper solar panels thanks to holographic (useful spectrum) redirection, osmosis power plants (if they manage to produce more effective membranes with nano tech), methane producing bacteria (yay for gene-tweaking)... well, its not like all that scary tech isnt good for anything. All these things are using sunlight (directly or indirectly). Finding a good energy source is "only" about finding a pretty effective way to convert that energy.
Oil for example is also just sunlight... well, damn old sunlight, but still... its the same thing if you think about it.
