Current international limits are 50 W/m^2. The sun at noon is 1000 W/m^2, so by that standard the rectenna is going to be very large indeed.

50 W/m^2 is absurd! One of the biggest problems with solar power is how much space it takes. Restricting yourself to 50 W/m^2 means that all things equal (which they wouldn't be, but still) you would be doing 20 times worse than normal solar power. For there to be any point in solar power satellites the flux in the beam must be much higher than the Sun's flux.

Are you sure 50 W/m^2 isn't just for some pathfinder experiments? It seems silly to have the same limits for radiation inside a power beam as everywhere else. It's a bit like having the same air quality standard inside a fireplace as in a city.

If you are such a whiny idiot that you think it should be OK to say "we don't serve your kind here", then you should have no legal or moral basis to claim that someone shouldn't be able to do the same to you.

Yes, I agree. People should be able to refuse to do business with someone for any reason whatsoever, and vice versa. Religious conviction shouldn't have any special status in law above any other type of preference or desire.

So either shut up, and accept that you have no other ways you're legally allowed to discriminate against someone ... or accept that it should also be someone else's right to refuse you because of your religion.

I agree and accept this.

>Or rectennas. You recall that SPSS's have a downlink portion, right?

The necessary size of the rectenna is set by the size of the microwave beam as it hits the earth, isn't it? Wouldn't that make its size not grow with the size of the array of solar panels in space? In fact, if all the sending antennas work as a single phased array, wouldn't you expect the beam to become smaller as you make the space array bigger?

Submission + - Systemd Devs Fork Linux Kernel (distrowatch.com) 3

An anonymous reader writes: Now it appears as though the systemd developers have found a solution to kernel compatibility problems and a way to extend their philosophy of placing all key operating system components in one repository. According to Ivan Gotyaovich, one of the developers working on systemd, the project intends to maintain its own fork of the Linux kernel. "There are problems, problems in collaboration, problems with compatibility across versions. Forking the kernel gives us control over these issues, gives us control over almost all key parts of the stack."
