Hello,

Obviously using a piston, you convert linear movement to circular.
Or using a turbine.

Other methods/mechanisms?

Pistons do not convert linear movement to rotational movement.

What are the parameters/limitations of this question? Is it homework? Have you googled it? This is very vague/open ended.

Is this one of those crank threads? :biggrin:
Two jokes for the price of one.

I did a Google search on your thread title (omitting "Methods to"), and got a bzillion hits. Maybe try that?

That's so often the answer to questions on PF.
Science is clearly not as well funded (on the internet) as marketing is. Once you are hooked into Amazon or eBay and you can't help finding the thing you want (or the thing they tell you that you want.
Just imagine this response from PF: "People who enquired about convert linear motion also found machines, inclined planes and levers of interest"

No kidding. Literally less than 30 minutes after I did some Google searching for typical images of Peltier generators with heaters, I got an advertisement in my other browsing for similar Peltier generator setups. Yoiks...
What is the heat source for your Peltier generator? What is the heat flux into the generator? What is the typical efficiency of the conversion to electrical energy? What power do you estimate you have to run the electric motor? Can you show us your calculations so far?

So what's the most efficient way to convert gas pressure into rotational energy?

I am sure that would depend on the available pressure. For high pressure you'd be talking in terms of a turbine but for low pressure, some wide area piston engine could be best (I'm thinking in terms of a domestic gas meter mechanism).

Since you aren't going to participate in your own thread, it is locked.
