CO2 To Fuel, Closing the "Carbon Loop" 316
leprasmurf writes "Inhabitat has posted an article detailing a recent announcement of a process to turn CO2 into fuel. The process, which used to be considered too energy inefficient, uses a multi-step, low pressure, and low temperature biocatalyst to break the CO2 into 'basic hydrocarbon building blocks.'"

There has to be some energy input if they're going to be breaking up CO2 and turning it into oxygen and hydrocarbons. There also has to be some source of hydrogen.
If they were able to get cheap hydrogen and electricity without using even more fossil fuels, we probably wouldn't need this process in the first place.

Can we please have a new Crackpot (or maybe Quackpot, or Snakepot, shit, I dunno) section on slashdot, specifically for these half-baked bullshit stories? Would make a nice replacement for Idle, methinks.
I mean, unless this was just meant to remind us of high school [wikipedia.org] science & biology. Heck, that'd also make a nice Idle section substitute.

Yup, these investor scams show up like clockwork on slashdot these days. One week it is a solar energy scheme that doesn't pass the smell test, some weeks it gets all the way to perpetual motion scams making the front page but lately there does seem to be a need for a green angle being pitched to make slash.
This one is almost certainly a scam. No mention of an energy source is the giveaway. You can't use a catalyst to add energy to a reaction even if you toss the bio- prefix into the ad copy. The diagram on the page does at least have something that looks like tanks but you aren't likely to collect enough solar energy to offset much of a power plant that way. Just feed the CO2 to real biology,,,, like plants, alage, etc. if you want to convert sunlight + CO2 into complex hydrocarbons.
Summary: Energy in energy out (Score:5, Insightful)
In the process called burning, hydrocarbons combine with oxygen and release energy.
To reverse the process (which is what they're saying) you have to put an equal amount of energy back in ... if it's 100% efficient, which it won't be.
The only way to get a net gain is to add some free energy from somewhere. The only plausible source is sunlight, but there's no mention of that on their web site.
Fact is, there's no science at all on their web site, just plenty of links for "investors", "investor FAQs", NASDAQ stock quotes, etc.
For credibility they have a link to a Popular Mechanics article but it's for a completely different C02 treatment process.

Yeah. I got those processes, too. They're called photosynthesis followed by another called fermentation and then (an optional) one called distillation. It turns out tasty by-products, too.

The sad thing is that these people, by killing nuclear power, have released countless amounts of radioactive pollution into the atmosphere, because coal plants actually emit radiation, but nuclear plants don't.
Sigh.
