well, flat mirrors don't reflect 100% of sun energy, do they? Ordinary metalised mirror is lucky to reflect about 50% of visible light, but shoudn't they hunt for more like infrared side of spectrum?

Dunno what you are so excited about with that BAS or Sensotronic system. It should be around for over decade now. Reason they implemented it is not just because drivers tended to underestimate braking distance and braking force, but because there is very distinct moment at the start of...

The only correct way of emergency braking is full step on brakes only leaving engine and clutch alone, and only when speed is down enough that engine stalling is developing can you press clutch. Reasons are many. 1) engine braking helps to decrease speed, additional braking force. 2) engine...

If you are not constrained by the laws of this planet, then yeah, its not a problem. If you haven't heard yet, the each country has some equivalent of FCC, and so does international waters. Anyway, in Antarctica or places like that, you are constrained by people there depending on radio not...

There are 2 concepts: infinity and infinite. They are all the time confused. What you seem to refer to is observational infinity beyond which we have no means to observe, today. Despite having finite volume, which seemingly is causing your resisting, it is not real bounds. Any point at 6billion...

Well, blue jets seem related. Why not suppose dust particles getting charged and accelerated by electric fields in the area? "The dust particles are accelerated to speeds above 100 kilometres per second. This is because solar radiation causes some particles in the outer regions of the A ring...

Is it a referring to Sprites & Jets? http://elf.gi.alaska.edu/

Start from FCC: http://wireless.fcc.gov/ Seriously, that's the main thing that limits you. Technically, useful bandwidth handled by radio frequency depends heavily on modulation techniques. Its possible to stuff way more signal bw into radio wave than the wave frequency itself. But it all...

That is true. And anybody arguing this can only beg to differ in definition of crap.

It would become a truly revolutionary wireless communication medium.

horsepower is product of engine torque and rpm. Take 3.0L engine, make it 300hp at 6000rpm, not a daunting task. Now make sure it sustains same torque at 18000rpm, and voila, you've got 900hp engine. So all the trouble is concentrated on reliability and combustion speed at those insane rpms.

You need current to produce magnetic field. Smaller wire will have higher resistance, so to get same amount of current you'd need more voltage. When you get to same current through both, same magnetic field will be made. In regards to power, its a measure of work done over time. Magnetic...

hmm, weird. I have checked this thread, but saw no answer to it. Now I see it was answered next day. weird.. Thanks for your hint. I'm thinking about how would it be possible to produce audible sound with as direct interaction with air as possible. What is the mechanism with O2...
