Response to Cryo cooling Stirling engines

<t><br/> David,<br/> <br/> That is uncalled for.<br/> Poor form!<br/> <br/> The question was if a Stirling engine could be used to drive an air conditioner in a car. And the answer is valid # no.<br/> <br/> Could a Stirlingn cooler be used directly off the heat to pump cool air back to take some of ...

Response to the Stirling and Hydrogen production

Catherine is totally correct, in that in the countries she is working with, they have bio waste that can be used to do things like pump water and preheat product, these are examples of positive feedback for a system, and should be encouraged.

Response to Power producing Alpha?

<t><br/> dispite the inability for anybody to give a credit card for a working Stirling to be shipped to your house, in the multi-kilowatts range, there are a handful of projects that have passed a certain threshhold of being able to produce that power with local bio waste burning heat levels, which...

Response to the Stirling and Hydrogen production

<t><br/> Q2 is easy.<br/> <br/> you are integrating the bio machine and the Stirling engine by means of both producing a common clean energy interface that only needs the simplest of internal combustion engines to exhaust only water vapor.<br/> <br/> Q1 - where the heck did you get such a machine? i...

Response to water pump

<r><br/> This is very cool stuff, and completely new to me.<br/> <br/> I saw one example of a liquid piston engine, but not so simple as this, and did not know variations have been in use for so long.<br/> <br/> I suppose there must be some downside or weakness, but something that pumps water can ma...

Response to how should i design a Stirling engine


You start by knowing what has been done already, and then pick a fatal flaw of the design, and take on the task of improving that.

Response to Project for Technikon

<t>Many will tell you what you taken on is too much. Please talk with your academic advisors, and propose this. You will take a working design of a solar powered engine, which does not have to be a Stirling, and you will build it. This gives you priceless experience with really building the engine. ...

Response to Configurations

<t><br/> Much has to do with what you have to work with and the purpose.<br/> <br/> A single piston engine has less machinery overhead, which is good, because of less drag on the notorious low powered nature of most machines relative to actual heat differece.<br/> <br/> A two piston engine will have...

Response to Thoughts on this Stirling Enginge Design Appreciated

<r><br/> If you have anywhere close to a working engine with even close the power you say, it would be a miricle. I went over your new design, I sorta followed your equations, and I think the machine probably is not going to even turn over! <br/> <br/> It is heavy and requires lots of external syste...
