I wrote about this a few months ago in this entry, but it appears that more progress has been made on this subject of science fiction and fantasy. Scientists at Duke University have managed to hide a copper cylinder. It’s still got a ways to go, it’s only 2 dimensional and still casts a shadow, but it looks as though progess is being made. Read this for details.

I got an email this morning from my Brother-In-Law with the link to Electoral-vote.com. Last time I looked at this site was on the eve of the 2004 presidential election. When tracking the election there, I thought there was a good chance for regime change based on this amalgamated polling data. (It really is a cool and informative site.) We all know how that turned out – so call me skeptical this time that these polls are any more accurate than the polls cited in 2004. I’m hopeful that we’ll see change (and I don’t mean the red blue change on the map – I mean real change regardless of party) this year where we can get back to core American values of honesty, integrity, fiscal responsibility, charity, and leadership at home and abroad. The past few years have been very costly in a number of dimensions. I do, however, want to go on record as saying I don’t think Democratic control of the Congress is “the fix” – whomever gains control needs to actually do something (and I don’t mean spend time on who their colleagues would like to sleep with.)

Here are a few more related tidbits just because. Post election, let’s revisit to see what degree of accuracy each represents:

• Approval of Congress at All Time Low (16% approve)
• Ohio can break Republican control
• Debate assertion that Bush has a “secret” plan to end Iraq war
• D.C.’s Political Report and Polls (like Electoral Vote)

Finally, November 7th, whatever your political views, get out and vote. It does make a difference. If you don’t vote, you don’t have any right to complain when things go pear shaped.

And I’m not talking about the movie of the same title… Do you know how much a cubic meter of dry air weighs at sea level?

About 1kg (1.0007 kg to be exact.) Air also has pressure, at sea level, about 10,194 kg/square meter (14.5 lbs/square inch.) Air also moves, you might have noticed this phenomena called wind. As the Sun heats the atmosphere air will naturally flow (convection) moving from high pressure areas to low pressure areas – it’s effectively a way for the atmosphere to move heat around.

So we’ve got mass and we’ve got movement which means that there must be a way to harness this excess energy flowing around the planet. For many thousands of years humans have used sails to capture the wind and for hundreds of years, sails anchored in place attached to a shaft converting wind energy to mechanical energy. This energy was used in the past to pump water, saw wood, grind things, etc. Today, high efficiency wind turbines are available and being installed for the purpose of converting wind energy into electricity.

Utility scale wind turbines


Each wind turbine has a shaft connected to a gearbox that drives an electrical generator. The turbines also have brakes, yaw and pitch controls, weather stations, and power transmission capability built into them (see diagram below.) Each turbine in a wind farm transmits its power to a shared substation where the electricity is stepped up to the right voltage to enter a supply line for the electricity grid.



The electric production capacity harvested from wind energy has grown from 2.8 gigawatt hours (GWh) in 1992 to 18.8 GWh in 2006 (trailing twelve month calculation.) Wind farms are now sprouting up in many different states across the US with Texas now leading wind production closely followed by California.

Major advantages to wind generated electricity start with fuel cost, $0. Wind farms are also very low impact on the environment in terms of emitted pollution into the atmosphere, ground, and water. In addition, wind farms literally provide another crop for farmers as the actual land usage tends to be small (less than 200 sq meters) for each turbine allowing agriculture to continue even as wind is harvested. Wind farms are also relatively easy to construct and put into service taking an average of 18 months to complete.

The major disadvantages to wind power are predictability of supply, one cannot guarantee that wind will blow when demand for power exists. Also, aesthetics, many people do not like to see ridges peppered with large steel towers with rotating props. And finally, avian impacts. In some wind installations, the death rate for birds, particularly raptors is elevated due to collisions with the props and towers. Each of these issues has solutions and with each new installation, the objections decrease.

Even taking into account the disadvantages, wind still is a vital part of the renewable energy portfolio and continues to grow at a fast pace.

If one can believe the polls, we might see some change as a result of this election. 74% of Americans say Congress is “out of touch.” It’s nice to be in the majority every so often…

Well, it’s Wednesday which means it must be time to preview the next Buckeye challenge. This weeks challenger? The Indiana University Hoosiers. While Indiana has been something of a door mat for say, oh, the last 50 or 60 years there is some sign of improvement from the boys in crimson and cream. They’re on a 2 game Big 10 winning streak having comeback in both games to beat Illinois on the road and upset then #15 ranked Iowa at home last week improving to 4-3 on the year.

The Hoosier defense is improving, but still woeful giving up an average of 29 points/game, 172 yards/game rushing, and 216 yards/game passing. The Hoosier offense is starting to click a bit with redshirt freshman, dual-threat QB Kellen Lewis getting into a groove, the reemergence of 6’7″ tall James Hardy at wide receiver, and speedster Marcus Thigpen at tailback/kick returner. The offensive line won’t scare anyone and is bound to have a long day at the ‘Shoe.

What’s going to happen: OSU will start a little slow, Hardy will create mismatches against the Buckeye corners, but the Bucks will put this one out of reach by halftime. Then Tressel & Co. will start “working on things” to help the team improve. OSU is a 31 point favorite, I don’t think they cover the spread in this game. Final score prediction, 45-17. Note: ESPN has decided to use this game is leverage. Consequently, unless you get a subscription to the channel ESPNU, you can’t see the game. That includes local broadcast in Columbus. My advice, listen and follow the game online. Don’t give them the leverage.
