Mark Goldes sent a message to Lloyd Blankfein that said:
Dear David Sachs,
Green Swans - highly improbable inventions with huge potential impact - can replace fossil fuels much faster.
See a few at aesopinstitute.org
They include cheap and easy conversion of engines to run on water - taken from the air. Vehicles running on water can be power plants when parked gradually replacing power stations burning fossil fuels.
Both piston engines and turbines have been invented that need no fuel and can supply power 24/7/365. They can replace intermittent wind and solar pv systems faster at much lower cost. The piston engines have been presented at 3 AAAS Meetings on The Second Law of Thermodynamics without refutation. Fuel-free turbines were prototyped in Russia before that government shut down the work, which threatened their economy. The turbines do not stretch The Second Law. Improved versions have been designed.
Look beyond Google - AESOP is viciously attacked by a ranting Troll. See THE FAKE "PHYSICS REVIEW BOARD" COSTS LIVES on the site - along with my Bio. I was an economic development consultant to Robert F Kennedy.
