(3BL Media/Justmeans) - What if we could take all that carbon dioxide that we have too much of and turn it into a clean energy source? Sound far-fetched? Well, it isn’t really. After all, plants do it every day. That is much of the rationale behind biofuels. Let the plants store the solar energy as sugars, starches, etc., which we then convert into things that our machinery can use (e.g. ethanol, bio-diesel).
