[quote="buickanddeere"](quoted from post at 14:42:00 12/19/20)

Reason why it is not done is because it is not worthwhile .

4165 lbs of water , maybe 835lbs of tank and framework for a 5000lb nice round number .

Raise that weight 20 feet.

100,000 ft lbs of potential energy.

1HP = 33,000lbs over 1 foot in one minute.

3.03 HP of energy for 20 minutes or 1HP for 1 hour.

746watts per HP.

That whole 5000lbs rig if it was 100% efficient would barely run a typical residence for an hour at night while you sleep.

Real world efficiency would be approx 66% .

Better off to find a wrecked electric vehicle and obtain 40 kwh of lithium batteries . No moving parts and it would provide 2 or 3 Kwh of power during the daytime peak electrical rate and charge at night during the lowest electrical rate .

Still does not break even unless you reside in an area with frequent blackouts or crazy priced power . Such as Hawaii, Ontario or most of Europe.[/quote]

I believe his question was a joke as was my answer in a sense.

You are correct it would be ncredibly stupid to think you could pump water up a hill and release in a head pressure type application with any cost effective benefit.

Stirling engines are neat. I bought a kit years ago and used a magnifying type ignitor. Just to play with.

Hydro, if you have the constant flow/pressure is a great option.

Solar panels and wind are self explanatory.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in ... [Read Article]
