Can Scientists Really Turn Seawater Into Jet Fuel?

By Boonsri Dickinson | August 20, 2009 10:45 am

matza74.jpgNavy chemists are claiming they can take seawater and turn it into hydrocarbon fuel—which, if it ever happens, would be great, since the ocean contains 140 times the amount of carbon dioxide held in the air. But right now, the notion of an endless supply of jet fuel from the Atlantic seems too good to be true.

Granted, the idea is gaining ground: Researchers are working on the process of taking carbon dioxide from ocean water and mixing it with hydrogen that has been split from water molecules. And Naval Research Laboratory chemist Robert Dorner has even been able to create fuel from refined seawater by tweaking a process that normally uses coal to produce hydrocarbon fuel.

But before seawater can become a gasoline resource, the researchers will have to figure out the right catalyst to use. In general, too much methane is produced when the wrong catalysts are used in fuel-making, causing fewer hydrocarbons to form—which means less fuel is produced.

So assuming it all gets ironed out, what are the chances this would ever work? Well, scientists have been able to take just about anything and turn it into oil, including turkey, poop, and human corpses—but these alternative sources still haven’t become anything close to major sources of fuel.

Experts Baffled by Unidentified Black Goo Floating in Arctic Ocean

By Allison Bond | July 16, 2009 1:43 pm

gooThere’s a mysterious black goo floating off the Alaskan coast, and no one is quite sure what it is. A helicopter flying over the area spotted a strand of the dark stuff, which is easily visible on the bright white ice floating in the Arctic Ocean, and followed it for 15 miles.

Juneau Empire reports:

“[The goo is] certainly biological,” [Terry] Hasenauer [of the Coast Guard] said. “It’s definitely not an oil product of any kind. It has no characteristics of an oil, or a hazardous substance, for that matter…. It’s definitely, by the smell and the makeup of it, some sort of naturally occurring organic or otherwise marine organism.”

“It’s pitch black when it hits ice and it kind of discolors the ice and hangs off of it,” [an official with the North Slope Borough’s Planning and Community Services Department] said. He saw some jellyfish tangled up in the stuff, and someone turned in what was left of a dead goose – just bones and feathers – to the borough’s wildlife department.”

Anyone wanna go for a swim?
