Gates-led fund is investing in a startup to build a cheap battery
- ohiovr 8y agoI've had some interest in personal steam engines over the years and I've found that they are far from cheap. Steriling engines are also not cheap. The issue is they don't produce a lot of work for the capital invested. Steam turbines maybe a better bet but it is tricky to make them small and cheap at the same time. Large, mighty and not too costly is no problem for steam turbines. Non perfectly dry steam can be a disaster for steam turbines I think I recall. So the quality of the heat is going to have to be very high. Maybe organic turbines could be a better bet as they can come in small packages. But even those are not exactly inexpensive.
