Joule's Biomimic for clean energy

You can tell this is a rah-rah piece, but I hope that it pans out.

They take sunlight and CO2 and turn it into energy? Amazing!

Wait, isn't that called fire wood?

I'm liking the methods being developed by Nanoptek and Sun Catalytix. These don't involve the creation of any creepy GMOs.

If it works it is exactly what we need. I fear they are spruiking for investors and it doesn't yet, and maybe never will, work.

Kind of, but I find the logs keep getting jammed in the carburettor. Ethanol is better for that.

But, yeah, same principle - use carbon bonds to carry the energy, but take the carbon from the atmosphere rather than the Earth's crust.
