Buoyancy wheel working in vacuum conditions.

Hi Low-Q,

You have some really good ideas, keep them coming. Here is a patent that uses the bubbles in the vacuum for moving a wheel.

Using your idea of an IR Led it might take less energy to get going on a smaller scale. Then combine the output shaft or geared with this patent.

I can make a small generator that is generating power to a small LED. It can be made cog-less like those in core less electric motors. If there is enough torque in the gravity wheel, it should be possible to run the generator in "overdrive" so it spins much faster than the wheel - just to scale up the voltage to trig the LED. I believe those 5mm IR diodes runs on approx 1.5 - 1.7 volts at 20mA. That would be about 30 - 35mW power. But I believe more than one is required to boil the alcohol in the vacuum tube.

love the idea


why not attach an LED on each side, or possibly inside to maximize efficiency of heat exchange

then alternately turning one on while the other is off

this way your still only powering one LED at a time, plus it would increase torque, as both are now subjecting the lever to weight distribution

unless you planned on turning the LED off while the lighter side was in the up position

It should also be possible to just make a short circuit coil with very thin wire and many windings, inside the tube, that heats up when passing a N-S-N-S-N-S-... magnet array on one side. Then we have 100% heat to "warm up" the fluids - no loss that is used to not heat the fluid. The wheel will face a counter force anyway if energy from the wheel is used to warm up the fluids. I guess the coil idea, with relatively high resistance, is better than using IR diodes.
