OK I figured as much would’ve been a little too easy to solve that problem like that would probably be needing something Iike 300,000 pound weight to run a refrigerator Oh well I’m sure we humans will figure something out you guys I mean not me I’m just a Carpenter I really appreciate...

OK so you’re saying work backwards I was pretty confident that solar panels could provide enough energy I just wasn’t sure how large the wait would need to be if the wait would need to be 50,000 pounds that’s pretty much a no go for somebody trying to put together a small scale system but a...

But like I said I was getting ahead of myself I just thought I wanted to make sure the numbers were even feasible before entertaining the idea

I just meant that if you build the system so that could be repeated using some sort of a renewable source of Energy lifting the weight up and down then it being such a simple system maintenance on it would be very little and the parts would be easy to come by there for making it a system that...

So if Our refrigerator uses 200 W then technically speaking if not taking into account efficiencies our system would run it for 33 hours?

I’m sure your calculation is more correct since I just google searched calculators and used online tools to get it .

Can anybody confirm this for real? Because if so it seems like a small scale potential energy using gravitational force and a 10,000 pound weight rigged up in the air at 30 feet would run a refrigerator basically forever if giving the components are maintained. Because comparison would have to...

Or no just Cut the previous 66 our number and half and you have how long you could run something at 200 W for 33 hours

I think the average refrigerator use about 200 W /second? Which would mean if it ran half of the day you were just multiply 200 W Times 36,000 seconds?

66hours?

So I calculated 414,000 J of energy for potential energy of a 10,000 pound weight at 30 feet high, so would I then convert this to watts?

Yes! My first thought was well what is the calculation for potential energy and then convert it to joules and then see how many joules refrigerator uses. But alas, I am an idiot and cannot find this on the internet. Sound like the term would be Gravitational potential energy equation

It does power a whole house

My main question is what would be the best way to find out how much energy a 10000lb weight elevated at 20’ would produced if attached to a power generator. This is vague but I am just wondering what it would be. All that work and it doesn’t even power a refrigerator? Or oh

Hi there. I am a novice but I was wondering what you all think is the most applicable mechanical energy storage device for small scale off grid applications is. I just read the thread on pump storage and it seems like a good idea but I thought I would keep it broad. Thanks!
