A genetic modification I like
A bug that eats waste and sh*ts petrol
Seriously.
Seriously.
To be more precise: the genetic alteration of bugs – very, very small ones – so that when they feed on agricultural waste such as woodchips or wheat straw, they do something extraordinary. They excrete crude oil.
Unbelievably, this is not science fiction. Mr Pal holds up a small beaker of bug excretion that could, theoretically, be poured into the tank of the giant Lexus SUV next to us. Not that Mr Pal is willing to risk it just yet. He gives it a month before the first vehicle is filled up on what he calls “renewable petroleum”. After that, he grins, “it’s a brave new world”.
...
Using genetically modified bugs for fermentation is essentially the same as using natural bacteria to produce ethanol, although the energy-intensive final process of distillation is virtually eliminated because the bugs excrete a substance that is almost pump-ready.
The closest that LS9 has come to mass production is a 1,000-litre fermenting machine, which looks like a large stainless-steel jar, next to a wardrobe-sized computer connected by a tangle of cables and tubes. It has not yet been plugged in. The machine produces the equivalent of one barrel a week and takes up 40 sq ft of floor space.
However, to substitute America’s weekly oil consumption of 143 million barrels, you would need a facility that covered about 205 square miles, an area roughly the size of Chicago.
That is the main problem: although LS9 can produce its bug fuel in laboratory beakers, it has no idea whether it will be able produce the same results on a nationwide or even global scale.
“Our plan is to have a demonstration-scale plant operational by 2010 and, in parallel, we’ll be working on the design and construction of a commercial-scale facility to open in 2011,” says Mr Pal, adding that if LS9 used Brazilian sugar cane as its feedstock, its fuel would probably cost about $50 a barrel.

The Varying Impact of Gas Prices
Gas prices are high throughout the country, but how hard they hit individual families depends on income levels, which vary widely. Some people pay up to 16% of their income on gas... 16%!

Technology will save us all
CO2 Catcher prototype has been developed
It has long been the holy grail for those who believe that technology can save us from catastrophic climate change: a device that can "suck" carbon dioxide (CO2) from the air, reducing the warming effect of the billions of tonnes of greenhouse gas produced each year.
Now a group of US scientists say they have made a breakthrough towards creating such a machine. Led by Klaus Lackner, a physicist at Columbia University in New York, they plan to build and demonstrate a prototype within two years that could economically capture a tonne of CO2 a day from the air, about the same per passenger as a flight from London to New York.
The prototype so-called scrubber will be small enough to fit inside a shipping container. Lackner estimates it will initially cost around £100,000 to build, but the carbon cost of making each device would be "small potatoes" compared with the amount each would capture, he said.
The scientists stress their invention is not a magic bullet to solve climate change. It would take millions of the devices to soak up the world's carbon emissions, and the CO2 trapped would still need to be disposed of. But the team says the technology may be the best way to avert dangerous temperature rises, as fossil fuel use is predicted to increase sharply in coming decades despite international efforts. Climate experts at a monitoring station in Hawaii this month reported CO2 levels in the atmosphere have reached a record 387 parts per million (ppm) - 40% higher than before the industrial revolution.
The quest for a machine that could reverse the trend by "scrubbing" carbon from the air is seen as one of the greatest challenges in climate science. Richard Branson has promised $25m (£12.6m) to anyone who succeeds.
Lackner told the Guardian: "I wouldn't write across the front page that the problem is solved, but this will help. We are in a hurry to deal with climate change and will be very hard pressed to stop the train before we get to 450ppm [CO2 in the atmosphere]. This can help stop the train."

Perils and fortunes of home ownership
Last night, we get a call from the local energy agency thanking us for their service. I decide to call them back - since they seemed to be working on a Sat, to tell them that our rented water heater was rusty. They said they'd send someone over Sunday morning.
Sunday morning, while the fixer guy was here, the hot water heater, now 14 years old, finally failed and began to leak. Needless to say, such a thing is a potential disaster - but fortunately, because he was here, we caught it quickly and got it cleaned up before our basement was flooded.
But, what are the chances?
