Small fusion generators. TAE, helion energy and ZAP energy are 3 well founded companies (combined $1B+) aiming at building ~50MW generators based on non-tokamak fusion. The generators are small enough to fit on a truck and could easily powe

Trains are ok if you have two or more nearby (<800km) walkable cities. If you need to get on a car to go the train station it doesn't make sense, you better go to the airport instead. Bay Area and LA are not walkable cities...

Exactly. Without good ad blockers (ie ublock origin) and other nice extensions (ie I dont mind about cookies) it is hard to browse/search the web efficiently. For this reason alone an ipad pro is limited in scope.

Most authors never make a dime. Most authors never get published. Most authors have no readers. Still they write. I think the point is to pay successful writers so they keep writing. Pay them and distribute ebooks for free. Where is the con

I would add one more point, as a general policy you might want people to read more not less. If ebooks can be distributed at no cost why make people pay for reading? It makes no sense. This cannot be the right way to incentivize and provide

There is a fundamental contradiction: - first as an author, want to be read, the more people read your books the better. - second as a human, you need an income. Imagine a charity (it could be government taxes as well) paying you proportion

I understand that books needs to be financed but why should we deprive the poorest from accessing culture knowing that marginal cost of ebooks is zero. We should incentivize reading books not making it harder or more expensive. - E-books sh

I do think tomakaks are possible. CFS and Tokamak Energy are getting there fast. But the 50MW shipping container size generator planned by Helion would be really transformative. No need to build near a river to cool. Order from the factory,

Daniel Jassby is kind of a joke in the fusion community. The self appointed expert that says that (almost) all startups in the field are BS. Journalists often cite him to "balance" their article with an alternative view. Tokamaks
