  • Biden’s party is more progressive, but Biden is not. Note how he is on par with popularity polls with the guy who attempted to lynch our political representation. Obama was easily more progressive.

    Edit: migrating my response to a deleted comment so others can read it. The deleted comment below accused me of not reading the article. This was my response.

    Sure did. It’s an embarrassing op-ed. Short and flimsy arguments. Every link is either something that someone else did (mostly state legislators) or about lip service rather than action. About the only thing Biden can claim credit for is related to the economy, where his policy has helped transfer wealth upward. If “progressive” means “keeping things perfectly as they are” then you can go ahead and be a progressive.




  • There is 1.4E21 kg of water on Earth. 0.03% of hydrogen is deuterium, a suitable fusion fuel. H2O has an atomic mass of 18 and O has an atomic mass of 16, so Earth has 4.7E16 kg of deuterium readily centrifuged out of ocean water.

    D-D fusion converts about 0.1% of mass to energy (4 MeV / c^2 / 4 Daltons). E=mc^2. So we have 4.2E30 (420E28) Joules of fusion fuel ready for us on Earth. We used 2400 TWh of energy last year. If we used this amount indefinitely then we would have 485 billion years of fuel.

    Bonus: deuterium depletion would have virtually no environmental effect.










  • Yes. pV=nRT. If you keep n constant (same number of particles), drop the volume (V) and crank the pressure (p) proportionally, then the only variable left is T, which would have to rise. This is called adiabatic compression. What’s being described is an engine piston the size of the atmosphere and a compression ratio thousands of times higher than what we can normally make.
