Where do you get a dish like that?

I guess the piston is the vibrator?

@7olusegun I admit to not really knowing how it works... :-/

i think more people woul dhave renewable energy if u didnt have to pay 10 thousand dollars to hook into the grid or spend thousands on batteries. someone needs to come up with a way we can just plug a solar panel into an outlet an the electric company gets it and reimburses us. i rent but i would buy a small solar panel a week if that was the case.slowly tearing apart my electric bill until they were paying me. if it was only easier hooking into the grid or storing the power.

Put an actual LOAD on it!

I know some one who is working on a thermoacoustic engine for car exhaust. His idea is to use the heat energy from exhaust gases and run another engine for cooling effect. I question this because I think adding another engine, may be thermoacoustic or Sterling, will add more weight to a car and thus more fuel is required to run the car. The benefit that one might get from using exhaust heat might get lost due to increased weight of the car. I don't know for sure!

@518schenectady I forgot the name of the company but they developed a wind turbine that you could just plug into an outlet and it would work like you are talking about.

I'd like someone to come up with a way to convert heat inside my car during the summer. A modified sterling engine? Something has got to be out there. This would earn an inventer a pretty penny.

Until we are able to get useable energy from any of these solar engines that we see on youtube! we could put them all into the class of the radiometer. we watch it spin and produce nothing! Now lets get busy and make these devices preform a usefull service! like out produce a photo voltaic cell, or pump water. any thing but spin! and make noise.

What ?

[boxa888]

iS THE tube at a quarter wave length of the tube, meaning 1/4 th the length where the main ocillations take place, in electricity it helps amplify electricity and current and from what i have read with air tube ocillators its the same, 1/4 of the wave means the highest point of energy where another "strike" of energy can be added and efficiently create a larger output in any device electrical or mechanical.

@crashfridh Thanx for the explanation.

[trainedproblemsolver]

It seems quieter than others, great work!

@518schenectady

I know this post is old...

but they do that now in Canada (in Ontario), the power company buys your solar power off you.

@MrLazyeyz Laws against being off the grid? I call bs. Cite such a law or admit you made it up.

There is actually a federal law dating to 1978 requiring utilites to by back power from qualified facilities.
