   but a weighted …
   but a weighted flywheel would turn longer even when the piston wasn’t powering it if a simply coaster type system were used. Something like the coaster on a bicycle that allows the rear wheel to spin even when it isn’t being powered by the chain.

   Yes, but without …
   Yes, but without some type of lubricant you run into one of the main foes of efficiency, friction. which in theory might help the hot side of the engine but is still going to lower the efficiency of the power piston.

   Most likely not it most like just has air at atmospheric pressure. (14.7 psi at sea level)
   The reason the video makes mention of hydrogen is because gases like hydrogen and helium have phenomenal heat exchange qualitys.
   Cleaning you engine by taking it apart should not hinder it in any way

   where can you find plans for making something like this? the only plans i’ve found so far are for making them out of old cans and other junk. i want to actually machine the parts, but have no idea of what dimensions to use….

   iam with you all the way,iam un egypt at the moment,maybe we could make a huge 40 feet prototype making 40KW to use as desalination unit,maybe turn the desert back into forests.

   Instead of having the engine turn a flywheel, have it turn a small magnetic generator.

    30kW for the big …
    30kW for the big dish is about 45.7% efficiency.

    Calculation:
    30 feet diameter is appr. 65.7 m2 (square meters).
    That is approximately 65kW solar energy on a clear day (depending on lots of factors, but this is a good starting point).

    Efficiency above 30% is extremely good for simple devices. 40..50% is usually achieved with combined cycle, that is gasturbine + steamturbine with
    steam generated using wasteheat.

    I guess having that in egypt would get full of sand? Well if you guys are interested I would like to do something like it in Mexico, just sun, no sand millons of homes!

    30 foot diameter …
    30 foot diameter stirling holds the record at 30% conversion efficiency but since size is related to efficiency that little thing he was holding is likley 2% effiicent on a hot day.

    yes you do , which …
    yes you do , which is the reason that the orginal stirling engines used air at 1 atm. Building hermedically sealed systems makes it possible for the newest versions to use high pressure hydrogen but even then they need peroidic refilling. High pressure hydrogen gives a lot higher efficiency and pays for itself very quickly .

    nuclear fusion can …
    nuclear fusion can be turned on and off like natural gas or oil. you can turn the sun on and off when you need it. you would simply need to re-vamp the current power plants to run with nuclear fusion. there would be no new infrastructure required and hydrrogen is the most abundant element in the universe so runing out isnt going to be a problm. it may not be re-new able per say, but you certainly wouldnt need 50 acrs of these to powr the u.s. and it will work when ever and where ever you need it

    this is a cool …
    this is a cool little thing and the huge version of it can run entire cities (about 50 acres of these could sustain the us indeffinatly) but its not practical. although it is theoretically possible, you would need to build so much new infrastructure, boatloads of massive battaries and new power lines that would be to expensive to maintain. besides, the average lithium ion battery can only be charged and discharged about 100 times before its total garbage. the future is nuclear fusion

    eeeeeehhhhhh……. …
    eeeeeehhhhhh…….good point but your also wrong. nuclear power is actually not effitiant at all, it just got so much government funding that that money soaked up (and is still soaking up) the losses. nuclear power obviously needs uranium, but that needs to be enriched for it to be any good. its only about 0.5 percent radioactive and that needs to be brought up to atleast 3% for nuclear power to be taken from it. the problm is that the enrichng process uses so much energy you actually lose som

    They need to fix the waste problem with nuclear power. Nuclear power carries a scare factor, dating back to the 1960′s. No matter how effective nuclear power is, until they can get around the waste and upfront costs problem, it’ll be a dead duck.

    I really hope this get onto the market! i think that solar is where it is, because people simply don’t like wind turbines enough (i like them). they think they’re intrusive and what not. this sterling engine idea is awesome though!
