I think your maths is off - there are 1m square metres in 1 sq kilometre, but 2000 kW in a GW, meaning approx 0.002 kW per square meter.
Which kind of makes this whole thing a weird economic proposition. You’re beaming energy from space at a density that approximates solar insolation, and still have to build the collector and convert it back - wouldn’t it be easier to just collect the solar insolation?

- robbiep 4y agoAhh thankyou for sorting me out. My apologies OP
- pencilguin 4y agoThere are, in fact only 1000 kW in a MW, or 1,000,000 kW in a GW. Where is this factor of 2 coming from?
