Fishtank-powered electricity???

  • We are currently upgrading MFK. thanks! -neo
^ Exactly. Generator heads need a lot of energy to spin them. Obveously the small the less energy it takes but the hydro-electric setup will not be 100% efficient, nothing ever is, so the inefficiency will kill this idea even further.
 
Hmmmmm, I know my ideas will probably not work, but what if you put the generator at the outflow of your filter, kind of like the biowheels on HOBs.
 
Perpetual power...what a concept...and you'd think somebody would have thought about that sooner.
OH wait...Our creator did!!...He gave us the sun, and the wind, and the brains to develop that technology...
WTH are we doing?

I guess we needed a Millennium, or so, to burn up a few billion Dinosaurs, to filthy up the planet, so we'd have to come to the realization of a clean renewable fuel to live...

And WE are the top of the food chain huh? :ROFL: :ROFL: :ROFL::ROFL:
 
okay-what if hes right but you first need your house energy/electric to get it started but after started you could then make it flow continuously with its own energy by a switch?In other words-you start with your house electric but once its going and creating energy-you can shut off the electric from the house and make it work the pump by continually making it flow back around and down to the tank-creating its own electric.wow-if you can make that happen-it would be sick.
 
Well, I need tgo figure this out more but so far....

A generator head that equals 500 watts equals out to be .67 hp (100% efficiency)
Wattage / 745.7 = Engine HP

1 HP = 550 foot pounds. Some how you convert that to pounds LBS and can use that to figure out at what head pressure would work and such.

I believe that it will take way more than we have available to turn a generator head.

I read that if from the axis of the generator head shaft is 1' from the center, then that is equal to 1hp and 1lb of pressure? I dunno.

It will never work....

The amount of energy required to pump the water up high enough to create any useful amount of power in a hydro-electric generator in a tank set up would be higher than the amount of energy produced so you'd still need an external power souce to run it, and the higher you flow your water down from the higher the external energy required to pump the water up would be. It just wouldn't work, you can't creat energy from nothing. Solar/wind power is the best bet, i have plans along those lines in the future.

yup yup yup....

arapaimag and johnptc would be the only ones on here who could maybe make something like this work but then the price involved it be better to add solar and wind systems for power...
 
Running 3 tanks without the pond on due to winter is costing me £120 a month(total), I remember a thread ages ago when someone put solars on the roof the cost was $10000 I think and would have paid for it's self in under 4 years, times change memory fails, but it's somewhere in the region
 
Its impossible, especially with a generator head that needs to spin at over 1800-2500 rpm. The amount of energy needed to spin the generator becomes less as you move out from the center of the shaft but then you are spinning the gen slower.

You may be able to power some very small low power gen heads, under 10 watts?. Research is key but you would need a lot of water at a great velocity with a good amount of head to make it work on larger gen heads. Especially when wanting to power your whole aquarium or house.

If you click on this link (just found it, havn't read everything) the guy is thinking of using a 3000 watt gen head on his 1000 gallon tank. He would have about 25 meters of head!

Its not a big help, at all, but just do a search on Google and you will find your answers.

As many people have already stated, there is no such thing as perpetual motion, conservation of energy doesn't allow it. Pumping water up to create energy as it falls is a losing proposition.

Solar and wind power are great, but expensive to set up and maintain. The best way to cut electricity costs is to make your tanks more efficient.

Insulating against heat loss is going to give you the best savings/cost ratio. The heater is by far the most energy-hungry equipment in a tank, so reducing the amount of heat lost will give you huge returns in energy savings.

A well designed filter would also help. This means properly sized piping without restrictions (if your valves don't say "full-flow" than they have a smaller port than their pipe-size). Also, unnecessary head height can waste a lot of power. Pumps should be properly sized and the lowest wattage for the required amount of flow/pressure.

If lighting is needed for plants/corals, reducing the time your lights are on will also be a very easy way to cut power usage.
