Ild switch from petroleum to ethanol and methanol based fuels for transportation; Convert the entire US power industry to solar and wind farming Ild start taking ocean water and convert it to drinking water/fresh water: send water (as in lakes of the stuff) to drought areas; provide fresh water for the entire world for free to the consumers Start farming chlorella (algae you can convert into astronaught food or methanol fuel) then give it away Pull all soldiers away from the oil security industry and put them to work helping developing nations+ countries with out armies to defend themselves. Then send mining colony volunteers to the moon, mars and the asteroid belt (6months out 6months back in shifts for the moon and certain asteroid crews) Build an orbital fueling and receiving space station Build an orbital solar power array (you could power the entire planet off of such a power plant) And launch all nuclear waste and nuclear arms (disarmed and dismantled) to be disintegrated into the sun's coronhesphere. And bomb the cr4p outa any nation or group who stood in the way of all this being accomplished.
