It's been 60 years since nuclear power was invented, so in 10 years it'll be available for mass market? I'd also like my watch form plane.
What if it's so energy intensive that a future dyson sphere can only power it once a year. It doesn't matter how cheap the machine is, if the resources are expensive.
- astrobe_ 13y agoIndeed energy conservashion and entropy equalizashion was a large problem.
- ElongatedTowel 13y agoThat poses the question whether a civilization that is advanced enough to build a dyson sphere would be able to build a second one somewhere else. The species would have enough time to collect energy and improve the machine until no reachable sun would be usable. And though we don't carry nuclear reactors in our watches (I guess smartphone would be more reasonable these days) we might carry fusion reactors in the year 38000.
