SPACE SOLAR POWER, again: Next-Generation Solar Cells Could Put Power Stations In Space.

Sure, and even with 100% conversion, you’d still need enormous acreage to produce meaningful amounts of power, and some way of beaming all that power down to the surface that doesn’t require vast land acreage.

But if they could somehow create a Larry Niven-style solar power textile with this nanomaterial technology, at least it might dramatically cut the investment required to build SSP installations, by making the collectors mass-produceable, compact, and self-deployable. The cheaper it is to build an SSP, the more likely it becomes that someone might try it, and that they will be able to afford to build one big enough to actually be worth the investment.
