Space-based solar power, JAXA suggests, could be in place by 2040. Solar power may not be the end-all be-all covering our energy needs, but it is clean, which makes it a good investment into our future. On problem, however, has to do with the efficiency of solar power . According to research, an oil well puts out about 27 W/m2 (watts per square meter), while PV (photovoltaic) solar panels, generate just 6 W/m2 , meaning that lots of lots of area is required to generate enough power to outweigh an equivalent fossil-fuel source. Of course, this explains why renewable energy sources aren’t taking over for non-renewable energy sources. We’ve talked about space-based solar power before, and most figure the technology is many decades away. PV solar panels themselves are nothing new, and neither are satellites bearing PV solar panels. So, the idea of a space-based solar power gen...
