Imagine if we could do solar in space.. infinite area- no soil wasted, the power transmitted as a ray of death... oh, so this is why we do not do solar in space

- ccozan 9y agoHow about building something similar to a space power station that loads huge batteries, then gravitationally launches them towards ground, while on the other side an automated system launches rockets with empty batteries that docks to the power station?
- pjc50 9y agoGuaranteed to be hugely net energy negative in the energy required to launch the batteries. Think about payload fractions and the huge amount of energy in rocket fuel.

- addHocker 9y agoLaunch Loop or Space Fountain are superior. Even the Laser Transmitted Energy solution is. Why? Because they do not have such tremendous costs to install and do not rely on hypothetical yet to develop substances.
- redcalx 9y agoTechnically it's not infinite. The sun emits about 10^26 Watts of solar radiation energy produced from the nuclear fusion of about 4*10^6 tonnes of hydrogen per sec, i.e. a 100% efficient dyson sphere would capture that much energy at most.
