mm307: Practical solar power from the desert

MUDGE’s Musings

Alternative energy technology has been of continuing interest in this nanocorner of the ‘Sphere©. One of our favorite posts discussed the emerging technology in some detail.

Today’s most emailed article out of the NYTimes details another take on solar power, from the Nevada desert. No shortage of sand, or, even better, sun. And much more predictable than wind (another topic we’ve looked at several times, most recently here).

MUDGE’S Musings

Quirky things going on out there, folks. None seem expansive enough to go all expansive on you, so we’re going to have another episode of SASB:

Gassing…

A couple of scientists at Los Alamos National Laboratory have, they claim, found a way to turn airborne carbon dioxide back into gasoline.

Scientists Would Turn Greenhouse Gas Into Gasoline

By KENNETH CHANG | Published: February 19, 2008

The scientists, F. Jeffrey Martin and William L. Kubic Jr., are proposing a concept, which they have patriotically named Green Freedom, for removing carbon dioxide from the air and turning it back into gasoline.

The idea is simple. Air would be blown over a liquid solution of potassium carbonate, which would absorb the carbon dioxide. The carbon dioxide would then be extracted and subjected to chemical reactions that would turn it into fuel: methanol, gasoline or jet fuel.

This process could transform carbon dioxide from an unwanted, climate-changing pollutant into a vast resource for renewable fuels. The closed cycle — equal amounts of carbon dioxide emitted and removed — would mean that cars, trucks and airplanes using the synthetic fuels would no longer be contributing to global warming.

Of course, there’s a hitch, there’s always a hitch.
