Hi,

We know that fluids have a boiling point that is depending on the surrounding pressure. In vacuum, the boiling point is very low - water can boil at room temperature. So I got an idea that might be worth paying attention. I was thinking of a gravity wheel which have hollow spokes - tubes -  with a thin and flexible membrane on each side that makes a small sealed volume on each end. In the middle there is a volume of vacuum which is sealed from the rest of the tube. Alcohol is filled in the remaining volumes of the tube - see picture. The center of this tube is attached to the bearing so it can rotate freely.

The membranes are there to prevent the bubbles to reach the other end of the tube. The drawing might not be 100% correct - it should be a part of vacuum in all chambers.

If one side of of the tube is heated briefly it will start to boil instantly and create a volume of steam/vacuum. This will displace the alcohol in the tube on the other side of the membrane, and reduce the volume in the vacuum chamber in the middle of the tube. The opposite side of the tube is still filled with alcohol. So now the tube is unbalanced, and will rotate.

The brief heating will be repeated on the other end of the tube when it has reached the bottom.

I think that it will take almost no energy to run the gravity wheel. If we somehow can use its rotation to generate a little heat to make stem/vacuum, the hope is that this wheel can run by itself. IR-LEDs can be used to heat one side of the wheel at any time.

How does this idea sounds like? If you have any solutions, alternative ideas on how to do this, you're welcome.

 You have been coming up with interesting ideas here lately. I can confirm the boiling in a vacuum for over at a friends house who does investment/lost wax casting. This would also make the water cold after boiling. Experimenting is the only thing I can suggest. I will have to hold off on any opinion though.

Thanks for the credits 
I would think this technology is based on a heat exchanger. The motor will depend on surrounding temperature. Lucky for us, we are living in an environment with temperatures I will do experiments on this. I think certainly this is an interesting approach.

How cool is that?! I really like this! I think that heat exchangers like this is the way to go towards free energy. The best of all - they do not violate the laws of thermidynamics, but are still free energy

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.

HEAT VAPOR DIFFERENTIAL ENGINE

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.

Miniature generator

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.
