piezoelectric power generation on an existing system IMO would be a decent one. Might could combine that with cativation (sp?) reduction or at least recoup some of the energy lost due to it with a piezoelectric system.
While you're building green chargers, or whatever you want to call them, you could build one out of solar panels, or copy the shake and charge flashlights, or if you've a little Ham Radio operator in you, build your own WiFi charger, which I'd bet could be modified to work with any cordless...
I found several sources calling this a "Space Tram" or Magnetic levitation launch assist.
Here are some links

I think you're referring to a railgun-type launcher. The tech is out there, the US Navy got one from BAE back in '08 and I've seen several homemade ones. The biggest problem is power generation and storage. Also, launching a craft would be slightly more difficult than launching a projectile...
So, is this assumed that the running observer is holding the flashlight? Or whatever is projecting the beam of light. From the way I'm interpreting this, you're saying that the speed of light is relative to the observer. Meaning that, an observer running parallel to a beam of light could run 99%...
First off, you have to understand that depression is fairly normal. Normal or not, though, if you let it, depression will take over your life and if you have an actual chemical imbalance then its very hard not to fall deeper and deeper into depression. Just being depressed doesn't make you a...
I got the fever a few days ago, but I'm to frugal to go buy a kit. So I spent the money on all the stuff I would need to build my own. Based it on the bot at the link below. You'll want to look into "BEAM robotics" for some true DIY stuff. BTW, the smaller the wheels on the bot, the better. I...
I like this and have similar questions. As long as we're measuring velocity of galaxies and stars, where is the reference point and how do we make sure that the reference point isn't moving in relation to the rest of the universe? Is there a way to measure velocity of the reference point and...
I see what Danger is saying. The pressure inside the underwater lab is high enough to keep the water from flooding, therefore your body is already accustomed to the pressure. So swim all you want, just as long as you don't swim immediately from the underwater lab's pool straight to the surface...
How about the faucet nozzles used on the sinks in chemistry labs? I seem to remember them being able to deliver one drop at a time for obvious reasons. Not sure where you could find them, but they should be able to handle high pressure. I would image the hard problem is going to be controlling...
I wondered what happened to that. You're right, of course (not just because we agree either lol). The trick is to make the passive system in use more efficient and to use it somewhere that has a lot of wasted energy that can be converted AND to way an efficient method to store the energy. Every...
Lets not forget the original rotor engine. Those are harder to beat, fewer moving parts = longer life. Plus better efficiency. Rotor engines have been in use for decades, the starrotor just looks like an American redesign. About time, too, sometimes we're pretty slow on the uptake.
