Not to rain on anyone's parade, but we've got devices that can deliver this at this size since a looooong time. There are many tiny capacitors that can hold 0.03 watts of power (and much more). Granted, the interface electronics aren't as easy since they have to deal with voltage variation, but still.
Guess this is another "green-sounding" technology that's being put into places where it will never perform. The way of the future is storing powerfull, yet small magnetic fields. The future is supercapacitors.
Yes but the athmosphere is rotating at the same speed. The only thing that matters is the speed difference ... 0 (give or take a few 100 kph). So that's not really the problem.
The problem is the weight of the cable. The cable will need to go up 35,785 kilometers. And while you'd be correct in assuming that the upper 1000 kilometers would cancel out their own weight, the bottom 34,000 won't.
But it would be the greatest thing since sliced bread for getting stuff into geostationary orbit. For one thing, it would end all energy problems on earth once and for all.
This thing IS scrap. I mean really ... 1) it has wheels, so it can't climb stairs or even cross the street 2) remote control, and still barely functional 3) that skeleton cannot carry anything, really, give it a basketball and it's joints will bend under the pressure, leaving you with still a piece of scrap, but one that won't move

"I'm in the market for a new laptop, and I want a 13-incher. I need something with a great keyboard for typing, as this will mostly be used for note taking in class. I am absolutely smitten with the XPS 13, but I'm afraid that with its age Dell is going to give it an update soon. Any advice for someone in my shoes?"
