Dead Forests to Fuel Vehicles

Here’s a resource we’ll have plenty of as ever wider swathes of our forests get decimated by pests like the Pine Bark Beetle. Dead trees. In an adaptation eerily reminiscent of Thomas Edison’s dictum We live like squatters, not as if we owned the property” a university has invented a technology to harvest one of the horrific effects of climate change.
The University of Georgia Research Foundation has developed an innovative way to turn dead trees into a liquid fuel and has licensed it to Tolero Energy in California. We could be driving on our dead forests as soon as 2010.
The technology represents a leap forward for the biofuels industry. Not only does the resulting biofuel need no additional refinement before blending with diesel fuel, but it is a naturally very low-sulphur biofuel.
And it would prevent additional CO2 from being released if the forest was left to decay.
But the biggest leap is in thinking of using a non-food source (at least for us humans) of biomass that we will have an ever increasing abundance of, as our climate gets worse and worse. And it doesn’t take scarce water resources to grow. Quite the contrary. Droughts and rising temperatures are all it needs.
Dead trees are one of the major sources of waste biomass, says Tolero CEO Chris Churchill.
LED Lighting with a Wave of a Hand: Sylvania’s DOT-it
From green gadgets and gizmos, to DVDs and loose-leaf teas, I get the occasional product sent to me for a review. In most cases, I like to give it a thorough once-over before I’m comfortable putting a stamp of (dis)approval on it.
If I take a long time to review a product, it is usually because: the product stinks and the manufacturer wouldn’t want me to publish anything anyway; the product really stinks and I don’t want to waste my time or my readers’ time with it, or; the product is actually quite good and the length of time spending reviewing it is extended because I’m trying to find something bad to say about it — but can’t. In the case of the DOT-it LED lights Sylvania sent me, the reason for my slow turnaround is definitely the last one. These lights are great.
The first of the two lights sent to me by Sylvania was the DOT-it Golden Dragon (pictured top). The ninja-sounding Golden Dragon is the Cadillac of Sylvania’s puck-style LED lights.
San Francisco LEEDing the Way on Green Jobs Conversions
In the quest to create new green jobs, we have the opportunity to take existing jobs and make them green.
Every city has architects, engineers and construction divisions. In conventional circumstances the activities these employees undertake can burn considerable natural resources. But in San Francisco, we’re working to turn these traditional municipal positions into environmental champions.
