Plug-Ins Panned, But Supercaps Coming

Tuesday, December 15th, 2009

ARS Technica describes a recent National Academies of Science report in an article, “New report offers grim assessment of plug-in hybrids.” Several commenters to the article naturally rejected the report’s fuel price assumptions as oil company fear, uncertainty and doubt (FUD).
Which reminded me about the promising EEstor breakthrough that’s supposed to be demonstrated this year, […]

If you’re confused why something tagged “Winds-day” is being posted on a day other than Wednesday, let me remind you that the universe isn’t tied to your homeworld’s orbital position. Not by a strong force anyway. Moving on. . .

Off-Grid Homesteaders in Pop Mechanics

Friday, September 18th, 2009

“The New Homesteaders: Off-the-Grid and Self-Reliant” is the title of the main feature of the October, 2009 issue of Popular Mechanics. The cover says it’s the “Self Reliance Issue,” but the largest font size goes to the word “SURVIVAL.”
Yet another indication that the recession is over and prosperity is right around the corner. (That was […]

Wind Power Costs, Risks and Progress

Sunday, August 30th, 2009

The cost of permits for a wind power system from various local government agencies may multiply the money you have to spend compared to just buying an installed system. Yikes!
Check out this outrageous item about Ventura County, California, “Will Red Tape Stop Green?”
Also, since finding out that the PVC cut-out blades for some homebrew designs […]

EEstor: Fast, Durable Electric Storage

Windancer Combines Art and Power

Thursday, June 25th, 2009

Wind Simplicity’s WindancerTM
One objection to wind power is the ugliness of the turbines.
Even T. Boone Pickens said he wouldn’t have one of the turbines for his own Pickens Plan on his property for that reason.
If small wind systems became decorative and attractive, maybe homeowner associations (HOA) wouldn’t resist them so much.
Thanks to a Twitter post, […]

Jet Stream Wind Power Is 16 Times Ground

A Wired News article, “High-Altitude Wind Machines Could Power New York City,” is also displayed at the CNN Tech section.
“The very best ground-based wind sites have a wind-power density of less than 1 kilowatt per square meter of area swept. Up near the jet stream above New York, the wind […]

Cheap Wind Power Choices

Wednesday, June 10th, 2009

TriplePundit reports “Small Wind Beginning to Make a Big Difference.” For those of you concerned with U.S. trade balance, there’s good news:
“What’s even more encouraging is that U.S. manufacturers–such as Mariah Wind profiled here on 3P–accounted for about half of total worldwide small wind turbine sales.”
For the cheap DIY folks, while I am skeptical of […]

Suburban Survivalists and the Windy City

Yahoo News reports a nationwide trend, Crisis spurs spike in ’suburban survivalists’:
“From teachers to real estate agents, these budding emergency gurus say the dismal economy has made them prepare for financial collapse as if it were an oncoming Category 5 hurricane. They worry about rampant inflation, runs on banks, bare grocery shelves and widespread power […]

It Usually Begins With Iran

Windpower in Iran
This headline was the title for my side of a debate (in the negative) on “Should the U.S. invade Iran” held at the Karl Hess Club on Monday, March 16. (Also, Jerome Tuccille’s humorous book, It Usually Begins With Ayn Rand, featured stories about the founding personalities of the modern libertarian movement.)
The gist […]

“They Sow the Wind, and Reap the Whirlwind”
– Hosea 8:1-14
There are some of you who held down steady jobs or ran businesses, paid your mortgage, invested in America and raised a family. Now you’re unemployed, your retirement investments went bust and your kids will live at home forever because their college money vanished too. Fools! […]

Winds-day

Thursday, February 5th, 2009

Here’s a direct link to the Instructables page for a thousand watt wind turbine project.
“We built a 1000 watt wind turbine to help charge the battery bank that powers our offgrid home. It’s a permanent magnet alternator, generating 3 phase ac, rectified to dc, and fed to a charge controller. The magnets spin with the […]

Solar “Balloon Engine” Power Generation

Thursday, January 22nd, 2009

This Kurzweil AI item links to a New Scientist article, “Balloon power isn’t just a load of hot air.”
“A greenhouse traps solar energy, providing hot air to fill the balloon. As the balloon rises, it pulls a tether, which turns a generator on the ground.”
Balloon power should be cost competitive with wind turbines and other […]
