What a great way to heat a column of air. At the end of it, what are we talking about, 90% loss?

- politician 4y agoWe already use microwave links at ground level successfully.
- iamleppert 4y agoThere’s a big difference to receiving a signal than to receiving energy with any kind of reasonable efficiency.
- politician 4y agoI'm sure you know this, but receiving a signal is the same thing as receiving energy. Take a random plot of land, build a grid of telephone poles, stretch conductive wire cables between the poles, and you've built an orbital power receiving station where the ground is still available for critters and plants. Make the plot wider to spread the energy over a larger area to make it safer for birds passing overhead, or narrower to punch out the atmosphere to improve the loss rate. There is a difference, and it's tunable.
