Minto Wheels
« on: April 10, 2005, 11:54:30 PM »
Hey guys

http://www.keelynet.com/energy/minto.htm

Has anybody here tried making a minto temperature wheel/device? Any Success?

I read that it only needs a heat difference of 3degrees, and that it produced a fair amount of toruqe.
The high torque of this could be used to reduce gearing so that the low rotational speed could be geared for higher output yes?

It seems a fairly plausible idea, but how could you get the difference in temperature without having to use "outside" sources (like burning oil). I know the sun could be an option ... although here in jolly old (not very sunny) england it could cause some problems :P

With the cooler weather here would it be possible/more efficent to invert the cycle so there is a cooling portion above and then somehow insulate the bottom porition to keep it warmer than the upper portion?

Just gathering more ideas

oh and does anybody have any suggestions for a simple cheap easy way to build one of these, as a test. not some super efficient device

How about putting methylene chloride into the tubes that are supposed to imbalance the wheels and since it dips below the surface of water, let it also be covered with a thin layer of felt (like the drinking bird) and as it comes out of the water and the minute heat dissipating from evaporation will cause an imbalance in the wheel.  Think of it as a circular drinking bird generator.  You probably wouldn't need that much of an ambient temp. difference.

Whaddya think??  :)

I like it, impractical, but a real treasure to show off to be sure

you could EASLY GET -O-V-E-R-U-N-I-T-Y WITH THIS. 8hp from a W-A-T-E-R W-H-E-E-L- (AND use an small electric current to heat the water)OR USE A Candle LOL!

Get some gears .. um Tough gears , it spins at 1Rev a minute but 8 Hp (like a diesal Engine,how powerful are diesal generators again? something like 5-7hp?)

While I gazed in disbelief, Wally explained how his incredible power wheel works (see diagram above).

A few weeks later I again visited the Kinetics lab. By then the propane bottles had evolved into 12 containers of steel pipe welded into a polygon. The principle remained the same. I watched as Wally opened the valve to let in a trickle of water from solar panels on the roof of his parking shed. The water temperature was 155 degrees F.

Almost imperceptibly, the wheel started to turn. The speed picked up a bit and I timed a revolution -about one rpm. Minto noted my misgivings. "Try holding onto the shaft," he said. I grabbed the shaft firmly - it was as if I'd tried to stop some eerie, irresistible force: no sound, no evidence of power, just pure twist.

"Picture one 200 feet in diameter," he said. This time my mind boggled. Such a rig might hoist the pyramids.

Wally doesn't expect industrialized nations to scramble for his wheel, and he isn't selling anything. He's donating it as a "gift to the world" and expects it will be used in undeveloped, energy-short areas.

For example, a practical 33-ft. diameter wheel running on a temperature difference of as little as 3 1/2 degrees F and producing several horsepower could pump irrigation water, grind grain, or saw wood. The materials could be scrap pipe, and no machining or skills are needed to build it. Several low-boiling materials might be used, but propane or R-12 may be best.

Minto estimates a slightly larger (40-ft.) wheel with 14 pairs of 1-ft. x 4 1/3-ft. containers would provide 10,240 ft./lb. of work per container as each 269 lb. of liquid responds to gravity through a 20ft. lever arm. At only one rpm this is 8.69 hp; not spectacular, but low cost and capable of running steadily for generations. The slow rotational speed can be stepped up to whatever is needed, just as with the old-time waterwheels.

No fuel would be needed in many cases. The temperature difference required between the liquid on the bottom and the top occurs naturally in many situations: water and air, light and shade, etc.

Minto has outlined construction details in a two-sheet paper entitled "The Minto Wheel." There are no restrictions on building or experimenting with the wheel.

a 8 hp engine can power a 5kw G-E-N-E-R-A-T-O-R.

How much power do you need to heat water , or even a bit of it?

why hasnt anybody tryed this / or have,......

0_0 OIL!!!! DRINK OIL!!!!

DOH!!!

THIS IS A ENERGY ALTERNATIVE ISNT IT?

AND ITS VERY SIMPLE TO BUILD THEN RATHER FIGUREING OUT HOW TO MAKE A STUPID MEG RUN.

And low cost and CHEAPER THEN A MAGNET MOTOR.

+GEARS + ALTERNATOR (IF YOU USE USED AND POSSIBLY NEW..)

AND USE THE ELECTRIC WHICH IS GENERATRED (AND I DON'T THINK IT WOULD TAKE MUCH TO HEAT WATER 2C , DO YOU???)

MORE LIKE 200 -500W > 3-4KW o_0.

THE ONLY DOWNSIDE WOULD BE ERM NOTHING .

OR BUY A 500 W HEATER

so Overunity can be made with this 19'70's motor

a 500 w heater is hotter then your Hand , so a sterling engine can run on your hand (low temp) , so Overunity looks GUARENTEED With this 70'S Machine.

It's not an overunity machine since the energy comes from the environment. Thermodynamically speaking, a heat engine. It would be good to adapt it so that the wheel runs in a slanting plane through a wall, sheet of timber, window so that the cold side is out of doors and the warm side indoors.

The joy of the drinking bird is that it doesn't need that. Could the drinking bird be adapted to rotate and then drive coils, magnets etc saving the back emf ?

Well from what i understand and have wised up despite my posts years back that i find embarrassing.


At the very best and this is full proof even in science is that you can use energy saving methods to save power but would not be overunity, absolutely nothing would achieve over unity and this is what i have learned.


Things like the back emf method is a energy saving method but would not give you overunity but at best with this method you are saving energy for example.


So yeah at the very best it would be energy saving methods but not overunity, anyone agree?


I think everyone would agree.



Dan.

I learned that you cannot get a heat pump that uses extracted energy to self run and be overunity you see so it runs off extracted energy entirely to self run with power left over which would be overunity, from the extracted energy.


If you did this then the overunity energy would be cut off due to the laws of energy.



If this would give overunity then we would be using overunity devices already you see.


So yeah take that with a pinch of salt, energy saving technology really giving a higher efficiency.


A cars turbo charger for instance is a energy saver technology but not overunity.


A rookie or newbie would think that this would be overunity even if successful it would be a energy saver at best and i repeat again that this is not overunity.


Same with the free electrons pump > http://jnaudin.free.fr/html/fep02.htm this free electron method is another energy saving method but never would achieve overunity.

Yes.

Apart from you in post 7, NOBODY is suggesting that this device is overunity. It isn't for reasons ranged above.

However, it might be useful as any heat pump is useful. It might also quietly drive some sort of Bedini, Adams or other device and thereby produce an overunity end result.

Do you have evidence for this opinion? (First and foremost, you need to understand where the energy in electrical overunity systems comes from).

The minto wheel is delightfully intriguing, the details of its complexities are obscured by the simpleness of the apparatus.

The costs of vaporization and condensation are massive compared to the shaft output.

To try and close this into a closed cycle seems impossible from the standpoint of offsetting the vap costs.

I have learned a method that pays for vaporization cost from stored and recycled internal thermal mesh energy. So it becomes a probability to close the cycle with abundance.

Trying to add exchangers of warm and cool sources is likely to alter the form of the wheel.

It is prolly best kept as a low tech environmental powered "thermal water wheel" for SHAFT OUTPUTS. I like it!

Discussion about close loop mesh exchange phase change goes off topic.

Best of wishes and thanks to Minto!

I need to revisit the comparison of vap costs to shaft output.

Much of the liquid is simply pumped/drawn upward by pressure change.

Only an amount of refrigerant needs be vaporized to gasify the volume of one cylinder! This pumps fluid uphill!

Moreover, cooling at the other end decreases volume drawing fluid uphill.

Energy for gasifying one volume of gas is very different than gasifying the entire fluid volume.

Does this have a shot at shaft output self-heating!
