Ice Age Sunspot Shortwave Solar Installations

Sunday, February 1st, 2009

Do I win a prize for the most bizarre headline? While we’re digressing, what’s up with “Cardinals” as a football team name? I think it’s fine for Abner Doubleday and Cooperstown, but on the gridiron a tweety bird is like a boy named Sue. Now give me some more tofu.
First some good news for energy […]

Virtual Bike Lane Lasers

Winds-day: Jay Leno’s Wind Turbine

Wednesday, January 7th, 2009

Yesterday, there was a Boing Boing post about Leno’s Garage and a video featuring a magnetic levitating wind turbine, which will be delivered to Ed Begley, Jr.’s house. Jay took great pride in his own larger wind turbine. He bragged: “Mine is bigger than Ed Begley’s.”
Oddly enough, perhaps due to the “carbon footprint” needed for […]

1895 Stirling Water Pump

Thursday, October 30th, 2008

I noticed this cool Stirling engine water pump a long time ago, but never got around to blogging about it. This external combustion motor is heated with a gas burner, but there are solar powered Stirling engines you can look at online, too. Built in 1895, it originally pumped water a hundred feet into the […]

Biodiesel Halves Landscaper’s Fuel Cost

Wednesday, October 22nd, 2008

A biodiesel research item about E Coli at Gas 2.0 linked from a front page Digg post led me to another Gas 2.0 story about a landscaper growing 22 acres of jatropha for biodiesel, with the expectation of saving half of the $24,000 per month formerly spent on diesel at the pump.
Looks like my “grow […]

Be Cool, Paint The Town White

Sunday, September 21st, 2008

Researchers have done the math on how much CO2 would be offset by more reflective cityscapes.
Given the day of financial reckoning to come, only delayed a bit by GWB’s bailout (the largest since the Great Depression), maybe ”Get Out Of Town” would have been a more helpful headline for you. But enough of my obsessions.

Paul Ehrlich Debates George Carlin, Kinda

Wednesday, September 10th, 2008

Here’s a debate between Paul Ehrlich and George Carlin (even if they never met). But first, some background on why I embedded their respective YouTube videos.
My motivation for this blog about permaculture is “carbon neutral.” Do ignorant government politicians use pseudoscience to whip up bogus threats? All the time. But do corporations cover their ass […]
