  • The converse is that SEO spam has become better at the game than google, despite google’s best efforts. It’s a less comfortable thought because how could a bunch of unorganized distributed actors out compete the one of the world’s richest company at their bread and butter game. The alternative is that one of the world’s richest companies gave up playing their bread and butter game.





  • 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.
