I met a European engineer up in Tuolumne a few years back.
He sais that his company builds systems where they pump water up hill for energy storage.

We've done this in Ca for over 100 years!

the Big Creek project, on the Sierra National Forest, is said to be "the hardest working water in the world"

"That is an ignorant urban myth. Does your neighbor know that it takes as much energy to make a gallon of gasoline as you get back out of it?"

This is also not true. ETHANOL from corn takes as much energy to make as you get out of it.

Soy Biodiesel delivers 3X as much energy as it takes to make.

Ethanol from sugar cane delivers about 8X as much energy as goes into it.

Regular gasoline varies on the source of the oil but is much higher.

I have read estimates that homebrewed or coopted biodiesel delivers as much as 10 times the energy as it takes to make it.

Yep,it is all fantasyland.

Money for nothing and the chicks for free.

Energy production costs what people will pay for it.

Interesting. Then why do energy companies make money?

F' the whales. Save a coal miner.

Best way to do that is to get the miner our of the mine, and add a decade to his life expectancy.

Also not true. This was the calculation, early on, when it was not known to calculate side benefits, such as using using the leftovers for feed. However, the original wrong calculation (by David Pimental, I think) has an eternal life on the internet.

Sorta like Benghazi..javascript:doSave();...
