  1. @Dqtube I was wondering what the benefit of this would be over using rock or sand. I think you answered my question. Aluminium is an excellent thermal conductor so the power of these bricks will be much higher than that of rock or sand.

  2. Blockchain to prove some unit of energy is green? This makes no sense whatsoever. Blockchain as such does not consume a lot of power, it is finding hash codes that meet certain requirements that takes a lot of tries to hit one. This is how new coins are created but it has no relation to the blockchain itself. Nor does a digital certificate being hooked up to some blockchain prove anything about the physical world. Smells like selling fried air to me.

  3. Using renewable energy to capture carbon from the atmosphere seems stupid to me. First we should use that renewable energy to do things we use fossil fuels for now. Carbon capture is a smoke screen from the fossil fuel industry, an excuse to allow it to continue business as usual.
