Biotech Company Making Fossil Fuels With a 'Library' of Bacteria
Saysys sends an excerpt from a story at the Globe and Mail:
"In September, a privately held and highly secretive US biotech company named Joule Unlimited received a patent for 'a proprietary organism' – a genetically engineered cyanobacterium that produces liquid hydrocarbons: diesel fuel, jet fuel and gasoline. This breakthrough technology, the company says, will deliver renewable supplies of liquid fossil fuel almost anywhere on Earth, in essentially unlimited quantity and at an energy-cost equivalent of $30 (US) a barrel of crude oil. It will deliver, the company says, 'fossil fuels on demand.' ... Joule says it now has 'a library' of fossil-fuel organisms at work in its Massachusetts labs, each engineered to produce a different fuel. It has 'proven the process,' has produced ethanol (for example) at a rate equivalent to 10,000 US gallons an acre a year. It anticipates that this yield could hit 25,000 gallons an acre a year when scaled for commercial production, equivalent to roughly 800 barrels of crude an acre a year."
Umm, because bacteria, algae and plants make hydrocarbons in exactly this method? The problem is the steps involved to make these kinds of chemicals (gasoline) are generally waste products (from other reactions) which poison the algae, making it difficult to get high concentrations/ lots of production.
It is not funny, since real liquid fossil fuels are created by archaea bacteria in the earth crust, with natural gas as input. This is well known, but it is a slow process. There is as much life in the upper 3 kilometers of crust as on top of the surface.
Excuse me, but please get off my Pennisetum Clandestinum, eh!
because photovoltaic are only 10% efficient?
while I agree electric motors would be far better for personal transports, the problem is storage. You can't store electricity in great enough quantities for it to work well. Until you can get 400 miles fully loaded with less than 1 hour recharge time, on electric motors, they will just not work in the USA. Right now the Tesla roadster has the best range of ~350 miles . driving 25mph with only one very light person on board with no baggage.
The USA doesn't have the bus, or train infrastructure to support moving lots of people well. Trains roughly take 2-3 times the time it takes a car to go the same distance.
i thought once I was found, but it was only a dream.
If you consider total consumption, not just imports, it would require around 15,000 square miles. However, the US has over half a million square miles of active cropland, and about 135,000 square miles just corn.
In other words, if you replaced ~3% of America's farming, or 12% of America's corn production with this type of hydrocarbon farming, you could replace all of America's oil consumption. Stick that in your corn pipe and smoke it, corn-based-ethanol producers.
Definitely too good to be true. The energy contained in 15,000 gallons of biodiesel ~= 10,000 gallons x 133,000 BTU/gallon x .000293 kwh/BTU = 0.58 MM kwh
The energy falling on one acre of land in the tropics ~= 5kwh/m2/day x 365 days/year x 4046 m2/acre = 7.4 MM kwh/year/acre
So they're capturing 8% of ALL solar energy falling on each acre of land in their fuel, assuming they are in the tropics and not in the continental United States. The efficiency limit for photosynthesis is around 14%, which isn't calculated on a per-acre basis, but on a molecular exposure basis. Even if you could cover each acre with pure chlorophyll, the conversion efficiency would not exceed 14%.
So they are claiming they will exceed 50% of the theoretical photosynthetic limit AFTER all the energy and efficiency loss of processing, for a net yield of 15,000 gallons? Total BS. If they claimed 1000-2000 gallons, maybe, but with their claims you can bet it's a pump-and-dump green stock scam.
