There is a twenty inches box which can be switched on the electric power supply. It can "work" for any time, it consumes much more energy (electric supply) than all of the losses (friction, radiation, vibration etc.) It does not store the energy, you can retrieve only a small amount. I really want to know weather it infringe the law of E.C. or comply - and I miss. I guess this "box" transforms the energy into an unknown form otherwise it could eliminate the whole energy of the universe -theoretically during a very long time period. If I get serious answers I will put it (pictures and some comments of it's principle -which is really simply) up to the net in some days.

In the news, you'll hear that a ship is a whatever-ton battleship, or a whatever-ton carrier. The Japanese whaling ship in trouble near Antarctica . . it is a 8,000 tonne ship. From what I gather, this is the water displacement of the ship (Archimedes). And of course we know how that works. But how do they find the water displacement. I suspect it is by adding some known weight. . . Any answers?

I'm looking for a good monostable multivibrator integrated circuit. It is also called a monostable pulse or one-shot. Ideally, I need a minimum input pulse width of less than 2 nS, and an output pulse width of 30 ns. A very fast rise/fall time is preferred. For example, the MM74HC4538 chip from Fairchild needs a 20ns input pulse, and can give me an output 150ns pulse. It does not matter if it is expensive, I just need something that is commercially available. Thanks for your help!

We have a large fridge unit at work. The compressor unit is mounted remotely in a steel cradle away from the fridge. I am told this should be earthed.
Am I right in saying that an earth cable should be attatched to the steel cradle and the other end of the cable bolted to a gas or water pipe that enters the ground?

The neighbor girl brought home a a rudimentary wooden car kit home from school. She brought it to me for a bit of help. Included was a piece of 1 1/4" dowel to be cut into wheels. I want to drill the centers for an axle. How do I find the center? I can do it on paper, but is there a tip for finding the center on wood? I don't want to have to buy a special tool for the job.
