Solar power makes a step

The much touted Nano Solar corporation, seems to be ready to actually ship it's first product. Supposedly it makes it cost competitive with coal. A welcome development.

Starting somewhere

I came across an interesting article on AJC.com about a couple in Grant Park trying to erect a windmill on their own property. For those who don't know, Grant Park is a tony neighborhood near the center of Atlanta that prides itself on diversity. Like most areas that pride themselves on diversity, it's composed largely of childless college-educated types who overwhelmingly vote for the Democratic party.

Needless to say the neighbors are contesting the windmill. While they're organized enough to put together a website, they don't seem to be organized enough to utilize the Coase Theorem. Needless to say, I'm for them erecting the windmill on their own property.

Before anyone asks, wind power is usually much more efficient (per dollar) than solar energy, and also has a much lower starting price. Also, modern windmills are geared to prevent fast rotation which protects birds.

The good side of ethanol

It would seem that the viability of ethanol is finally being questioned in the environmental movement. About time too.

Monday link roundup

  • An in-depth examination on how to build an energy efficient house
  • Robot snipers in Israel
  • Strobist begins Lighting 102
  • No one thinks seriously about alternative energy. Check out this post from TreeHugger "New Battery Pushed Prius to 125 MPG". It's a great idea and invention, but it's a plug-in hybrid. The motion is coming from the power grid. Granted electricity is usually more efficient than gasoline, but that's like saying that a diesel engine gets infinite mileage because it doesn't burn any gasoline at all.

Worm gears and motors and robot, oh my!

As my mad scientist phase continues, I've come across a few cool supply sites (some from Mark)
In other news, I just ordered 3 sets of brass robot gears for ten bucks from E-Bay. They should arrive soon.

Wind Power in Popular Mechanics

Popular Mechanics has an interesting article on Wind Power on their site. Sadly, it makes it seem unworkable on any kind of large scale. It would be quite handy on a small to medium scale though.

A mad scientist period

For some reason I'm going through a mad scientist phase right now. My current idea is pair a passive solar heater with a Stirling engine and see how much power is actually generated. Hopefully I'll have time to work on it in a few weeks.

The tin can Stirling engine

I came across simple plans for a tin can Stirling Engine on the interweb, I think I'm going to build one. I've had some thoughts on how to pair one up with a solar chimney that might actually work. I'll keep everyone posted.

Manhattan project for energy independence

Some ideas never go away; to wit, in what way does the statement, said by many "we need a Manhattan project for energy independence differ from Soviet industrial policy? It's quite different from the original Manhattan project in that it's quite wide in scope and chases an ill defined goal, whereas the original Manhattan project was quite specific in both method and destination.

Benchmarks of seriousness

I was taking an advanced economic history class during the Republican "Revolution" of 94. Someone asked the professor if there was any historical precedent for radical change following a big party switch in Congress alone. He cited many near examples I don't remember but then said "We'll know if they're serious about cutting spending if they get rid of farm subsidies.". It's now more than twelve years later and farm subsidies are going strong.

I was reading this interview with George Schulz and he, talking about oil dependence, had the line
I won’t believe we’re serious about it until we’re willing to remove the tariff on import of ethanol. And take quotas off sugar and a few things like that.
which is a fine benchmark to tell if anyone really cares about oil dependence. Support for nuclear power is a good one too.

For some technical background; American ethanol production is one of the least efficient efforts in the world, largely because we make it from corn (which we have a lot of) which is a poor source material. Sugar (of which we grow very little) is a far better source material. The American climate is not well suited to grow sugar, but it is well suited to grow corn. Both the corn and sugar lobbies are well organized and powerful and benefit greatly from subsidies and tariffs.

Passive solar power

Via TreeHugger.com, I came across this interesting how-to article on passive solar power. An expanded article can be found on Instructables.com.
