Thermodynamics is a b!tch. My daughter is an engineer my nephew is an engineer my brother-in-law has a masters in physics and a highly technical job...... So Thanksgiving dinners can be fun sometimes!

Thermal dynamics for dummies can be broken down this way. There are three laws.
1) You can never win the game
2)  You can’t even break even
3) and you can never quit the game.

Which part?

I learned a lot working for a carbon fiber company. Some of the mechanical engineers, Chemical engineers and material engineers there were brilliant. If I could go back in time, I would go that route.

Eagles and all kinds of birds get killed by turbines but our fair and balanced media ignores that. Spill a bucket of oil and you’ll see a oil covered seagull on front page.....

Heat is loss of efficiency so correct on LED. Perhaps a better analogy is this: A 15th century Dutch windmill compared to a modern carbon fiber bladed wind turbine is the same as comparing the first lightbulb to a modern LED. The problem is the LED represents nearly the end of the highest possible efficiency. And today’s wind blades represent nearly the end of the highest possible efficiency in wind turbines. We just can’t squeeze much more efficiency out of it.
