how much energy

Elizabeth, one thing you don't mention is how much energy the proposed array will produce.  What is the efficiency of the whole system?

On another note, why use robots to assemble this.  Why not the International Space Station (ISS)?  It has a robotic arm and people to do the work.  This would have lots of benefits.  First, there is cost.  The whole robotic assembly is not a part of the technology of power generation.  It is a whole other program requiring diffent skills and really raises the cost and complexity of the system.  I expect that a demonstrator would be built (a single satellite) and then a larger array, then the full envisioned array.  That's a lot of steps.  Getting rid of the robotics in the early stages would speed things along.

Ha, yes, TJ, it does seem the stuff of scifi and I am sure there will be naysayers that claim it's dangerous and it shouldn't be done. I personally think it's a great idea and, given the fact that we use solar energy naturally anyway, it would be hard to argue that this is dangerous for humans. But I guess you're right in that the transition from solar energy to radio waves that will be "beamed" down will spur panic among some!

Sci Fi to Reality

I love when the science fiction I read in my teens (Aurthur C. Clarke, Robert Heinlein, Allen Steele to name a few) becomes reality in my lifetime.

I hope this concept is strong enough to overcome the

DEATH BEAMS FROM SPACE!!!

headlines that will inevitably follow.  High tension lines have always been a favored target for health scares.

Complicated yet simple

This idea, to me, seems both very complicated and simple at the same time. Satellites already use solar energy, and where better to harvest energy from the sun than the place where the sun is located. While what Jaffe has already designed and built is promising, it also will take a significant amount of investment and technology to get it where it needs to be for this to become a reality. Still, this is fascinating stuff and could one day revolutionize renewable energy, at least that from the sun.

It's been two years since the Mac Mini's last appearance on iFixit's teardown table, but a newly revised version joins Apple's lineup this week.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Kevin Gautier of Formlabs describes the making of a carbon fiber mold for an intake manifold, using a $3,300 3D printer, during Medical Design & Manufacturing Midwest.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
