Can I Generate Energy from Lakes to Clean and Revitalize My Backyard?

[nduka-san]

the description of the plan for it is to have a water turbine underneath the water for a unclean pond or river than using a turbine some turbines i was thinking of modeling are these two but on a smaller scale

Those work with flowing water. As far as I can tell, you don't have running water.

ok then what would u suggest for a pond

Unless you've got flowing water, nothing. There's no way to extract work from it.

A diesel generator.

There are some approaches that could yield results. Though a $1000 budget may preclude some of these.

Use the pond as a heat source for a heat engine if you can find a colder heat sink somewhere.
Use the pond as a heat sink for a heat engine if you can find a warmer heat source somewhere.
Use the pond as both source and sink and tap the differential set up by evaporation or solar heating.
Lay solar cells on top of the lily pads.

Tap the power in the tiny ripples created by the wind.
Build a fusion reactor and use the hydrogen in the water to power it.
Stop the Earth's rotation for a while and tap the rotational kinetic energy in the pond water.
Start the Earth's rotation again and tap the Earth's kinetic energy as the pond spins it down a bit.
Sell boat rides and buy electricity.

Edit: We've ruled out a plain old wind turbine. But if we built a boat, put a windmill on the boat and used it to power a propeller to move around the lake, we could have excess electrical power that we could use to boil water. And we could still sell the rides.

I think "covering it with solar cells" and "selling boat rides" are the only ones that might yield appreciable power.

wow I turn off my notifications and you guys came up with great stuff thanks

for the ripples how much energy would that give (I know its not a lot)

Wiki has some info on wave power generation, including the formula for you to work out the energy for your unique situation:
