Combination of these two on a large scale might me interesting:
* creating energy from filtering co2 out of the air, http://www.sciencealert.com/a-canadian-start-up-is-removing-co2-from-the-air-and-turning-it-into-pellets http://www.sciencealert.com/a-canadian-start-up-is-removing-...
* turning salt water into fresh water, http://www.sciencealert.com/scientists-are-turning-salt-water-into-drinking-water-using-solar-power http://www.sciencealert.com/scientists-are-turning-salt-wate...
A energy neutral way of irrigating desert (Sahara , large part of California), reducing sea levels, and reducing co2 levels in the air.
- 2sk21 10y agoIn a similar vein, one idea that has often crossed my mind (and offered free to any taker): In most tropical coastal areas, there is an abundance of both humidity and sunlight. So why not use large banks of solar powered dehumidifiers to extract moisture from the air as water?
- DennisP 10y agoIt's possible to create fuel by filtering CO2 from the air, but the filtering process requires energy, and so does converting the CO2 into fuel. We'd need to use an abundant carbon-free energy source, like solar or advanced nuclear. I still think it's a great idea, as a backup plan for carbon-neutral transportation in case electric vehicles don't take over the world in the near future.
