    researchers designed a model that could generate 753 MWh of energy annually. That’s enough to power roughly 753 homes for about five weeks

    Why can’t the writers of these articles make useful comparisons? Can they just not do basic math? Each tower can generate enough electricity for about 72 homes… period. Just say that. No apples and oranges required.

    The TTSS works out efficiently in a hot, dry climate. […] researchers also note that reliance on a continuous supply of large quantities of water is an issue that needs to be addressed.

    These two things don’t really add up.

    I suppose you could feed it with saltwater if you’re on the coast, but there’s a reason why you don’t pump that stuff around unless you really have to.

      I missed the part where they pump water up to generate power from the downdraft (of cooled air). I don’t want to shit on cool ideas. Maaaaybe there’s are range of parameters where this works, but I’m holding my breath.

    All these pseudo innovations because challenging consumerism and capitalism is not even an afterthought. The size of this shit…

      It uses a ton of material to power 73 homes annually (652 feet high and 45 feet in diameter), works best in a desert but requires a lot of water. Yeah, nuclear energy is really threatened by that. Modern microreactors in development make, for example, 1.5 MWe at let’s say 90% capacity factor. Assuming about 1000 kWh/mo for a house, that microreactor, which can fit on the back of a semi truck and be transported down the highway that way, can power 985 homes anually and doesn’t require cooling water (will require water for electrical steam generation).

      Yeah, I will stick with nuclear, thanks.

        Nuclear energy isn’t threatened by this. It’s threatened by the fact that it’s impossible to build one at a profit.

          There are technology (reactor) demonstrations planned within the next 2-3 years, so not quite but very close. A lot of active R&D work going on right now for specific designs at a lot of companies.

              The technologies on which these reactor designs are based have been demonstrated previously. The specific designs are in progress and well on their way. AGR, EBR-II, and MSRE are examples.
