My doctor, who knows that I understand physics and renewable energy in particular, asked me today what I thought about wind turbines on boats.
I explained that, since boats need their own ways to generate electricity, what is called “small wind” may make sense. Most ships have diesel-powered generators, and that’s an option for smaller craft as well, and solar is not an attractive option because of the small area.
Doctors generally don’t have time to kill, but he asked me further about small wind, to which I explained:
Because the area of a circle is proportional to the square of the radius, big is better. If you can build a turbine with a radius 100 times larger than a small one, you’re going to generate 10,000 time more power.
Because the power generated by a turbine is proportional to the cube of the wind’s velocity, if you can site a turbine in wind conditions that are 10 times those on your rooftop, with trees and other buildings slowing the wind down, you’re going to generate 1000 times more power.
So, as usual, the answer resides in physics and math. 1000 times 10,000 is 10 million, which is why we see huge turbines on structures that lift huge turbines high above the ground, and it’s why the small wind industry has essentially disappeared.
If you don’t understand elementary school math and high school science, and you have money to burn, the investment offered at left may be right for you.
Most Americans who have the means to travel have rented a car in Paris and driven it all over France. I happen to be the first Avis renter to pick up a car at Heathrow and take it through the Chunnel on my way to Paris, on my way to Stuttgart in western Germany.
How much French do I know? Close to zero. I don’t even know the French word for “zero.’ Was I a menace to the French? Doubt it.
This strikes me as pure MAGA racism. It’s an appeal to punish people with brown skin, or preferably, take them and their little children into detention and ultimately deport them. The more pain, the better.

Today’s America admires the rich, and we have no problem if our leaders are sociopathic rapists.
The more damage they do to the common U.S. citizen, the more we love them.
All they really need to do in order to retain our adoration is to continue to punish people with brown skin and give tax breaks to billionaires.
Quality education, healthcare, protecting our environment, and affordability are all issues for woke communists and sissies.

Let’s not rush to judgement here.
OK, he’s an alcoholic Fox New host who’s led the U.S. military into a huge quagmire that, day by day, continues to destroy the U.S. and world economy.
My gardener is just as well qualified to lead the largest military in human history.
But Hegseth is 100% loyal to Trump. Nothing else matters.
