When I see cheaper fuel at the pumps I'll pay attention to crap like this.
... not to mention... "feeds solely on carbon dioxide" ... where is it getting the hydrogen for the fuels it's producing then? no, they're leaving out the fact that the bacteria will need some sort of energy input to produce hydrocarbons from co2 and h2o. The same way plants need it, imagine that. So I see two choices, photosynthesizing bacteria that produce hydrocarbons... which would be slow and inefficient, or bacteria that consumes organic matter to produce hydrocarbons... which would be slow and inefficient and require oodles of organic matter to feed.
so biofuel. What a pipedream. Is it even fuel positive in it's cycle? Counting the oil required to produce the organics (corn) to feed the system to produce the fuel.
You really should read up on the technology before you bash it. There's also this other thing called sunlight
, that the technology uses. Here, in case you were curious:

Joule took a different path. It uses genetically modified strains of cyanobacteria, which are water-based organisms that make their food through photosynthesis. The organisms, created by a scientific team led by Joule co-founder Noubar Afeyan, can be tweaked to produce different fuels—one form can produce simple ethanol, while another generates more-complex diesel molecules.
While regular algae has to be harvested and processed to squeeze out hydrocarbons, Joule's cyanobacteria release fuels continuously.
Joule's other innovation is its SolarConverter bioreactor, a system of closed tanks that look like solar panels, where the organisms grow and release their fuels. Designed to maximize the amount of sunlight that reaches each organism, the tanks mix the cyanobacteria colonies with water laced with micronutrients and piped-in carbon dioxide. Liquid fuels are separated from the water and piped to nearby tanks for storage.
Photosynthesis isn't hocus-pocus. It's an established method and the company's research is quite reputable. This isn't the dirty idea of "biodiesel." This is not a situation where you have to take a cellulose/starch form and convert it to fuel. You let the bacteria do what they naturally do--use photosynthesis to live--and then also tweak their DNA such that the by-products they make are ethanol (or some other hydrocarbon that you can use instead of fossil fuels), or some other hydrocarbon. The advantage of joule is that they have demonstrated that they can generate adequate quantities of pre-fule materials on a large scale.

It's not free or even cheap to develop new technologies. They should have some sort of protection to recoup their investments for a period of time.Edited by guyladouche - 1/23/12 at 8:52pm
