I'm surprised to see an American concerned about Canadian Law. We Canadians have lost a lot of rights and freedoms in the last decade for sure, but nothing like what the Americans have. In Canada we now have American style asset forfeiture laws at the provincial level. The laws came on the...

Make your life easier by replacing (1+r) with x. Have a common denominator of x^3 and cancel it out by cross multiplying or just multiplying both sides by x^3. Remove all like terms from both sides. Then replace x with 1+r. Expand the terms and remove all like terms on both sides. At this...

Maybe Tesla found a way to get energy for free. There's no shortage of energy in the universe. The Earth intercepts only one part of 2.205 billion parts of energy which the Sun puts out. We still can't reproduce his ball lightning. Maybe he was a nice guy.

This is an excellent question. From observation we know how it works and have many equations to model this with. But I think you are more interested in knowing why magnetism works. As far as I know, nobody knows the answer to that. The best explanation so far is given by Feynman; see link

Spelling error on my previous post. "Mandaleiv" shoud read "Mendeleev". Can't spell to save my life.

Faraday, Newton, Planck, Curries, Tesla, Galileo, Edison, Mandaleiv, Bohr, come to mind quickly. Newton is my favorite followed by Tesla. Although Galileo in his time was the best of the best. Too bad he pissed off the Pope and had to spend his last years in house arrest. The Pope must have...

What do you think "Free Energy" and "Action" mean? You need to provide a lot more information if you want people to know of what you are speaking of. As it stands; for me "Free Energy" is internet fun and "Action" is movement of an solid.

Energy in an inductor is equal to the current squared times the inductance all halved. (E=1/2*L*I*I) This is based on a one second interval. With AC it gets a bit tricky. You establish the 1 Amp current flow in one direction then reduce it to zero and then make it flow in the opposite...

I share Nano-Passion's confusion. Yes, energy is the ability to do work. But how is that work actually done. We see work being done by changes in matter. Parameters of matter such as shape, motion, temperture and densisty all change in response to energy. Something as simple a two objects...

Since the superconducting magnet is lifting a load, it is coupled to it like a transformer. That coupling will limit the current even though you are pushing electrons into a superconducting material. Once the weight stops moving, the superconductor will reach full current flow. That's my...

If you are worried about the low pressure pump, just protect it with a check valve. As long as the pressure at the mixing point is less than 10 bar, you won't have a problem.

Youtube is just a media for information exchange. The MIT lectures are very educational, I agree. The NASA water sphere experiments are mind blowing.(Bubbles going down instead of up.) However, I was just pointing to one video which suggested that black holes release matter. My previous...

So the universe is destined to die of thermal equalibrium. What about the new theories suggesting that black holes shoot out matter at their poles. See "http://www.youtube.com/watch?v=gib2i3_KW5Y&feature=related". Wouldn't the disturbances caused by those processes prevent thermal death of the...

So thermal energy is the exception and not the rule? You can convert electrical energy with 100% efficiency to heat, but never the other way around. So is energy not conserved when it is in thermal form?

Isn't energy the ability to do work? Batteries, springs, flywheels, etc. have energy because they can do work. When they can no longer do work, they have no more energy left.
