S3V2 V-twin heat engine(vacuum/Stirling)

Mechanical 3D art, made from re-machined scrap metal.
Cast iron pistons & barrels. RPM=120~750
This is 1 of the few bikes 1 could ride & never get a speeding ticket or stack.

Forgive me my ignorance but what is the power output of such an engine?Or does it simply stop under load?I am most impressed by the whole thing.

[zacqt]

@Squarerig , power is about 0.0004824 hp , or will produce 1.8volts/.2amps. Or Will make a small flashlight fairly bright.

The other video on my channel of the flat twin produces more power(flat twins are always more efficient then any V-configuration) , the trick is with these machines is to try to reduce as much friction and vibration as practically possible. The vacuum engine was around before steam power. The flat twin will run on solar power also. Thanks for your comment. GST.

would you sell this?

[zacqt]

@gauthier6916, thats sort of what i do for a living.

single cylinder(around $850Au), flat twins(about $2K Au), V-twins(like this one,around $4.5K Au) .Or any number of cylinders & or any configuration.

Some have DC-power genorators. This V-Twin was ordered/delivered for a 50th birthday present a few years ago. Theoretically they could last hundreds even thousands of years in reasonable enviroments. Some pay a fortune for a picture to hang on the wall, i like 3D mechanical art. thanks GST.

@zacqt Why do they cost so much?

[zacqt]

@waynerd23 , RE cost, the main reasons for the "heavy price"is because:1. Not mass produced. 2, These items are made to last for a lifetime +. 3, limited numbers of models in each series. 4, The "market place" sorts out the real value of most things, its hard to recover the amount of hours that go into these machines. If i could produce these items cheaper i would. If these items where mass produced the price would drop dramatically but so to would the novelty, artistic-aesthetic value. Cheers.

Facinating!!! ----Brilliant!!!--- it really gets the mind going!

Great post!

What a masterful mechanical balance with allusions to the harley.

[MrNorton1967]

@reclusful this is a friend of the maker and i own a single that he made. the valve is made of steel, the blade that holds it is a feeler gauge blade, intake hole about 5mm but this can be of a smaller,stroke is 65mm.bore26mm rod is alli, piston and barrels are cast iron, with big end and mains bearings from computer hard drives,but as u can see there is many of these creations but steve is a true genius

[headsmess]

if i was all cashed up i would pay for 3d mechanical art...as well as more machinery so i can make my own!

though even old machinery is art in itself...they dont make mills like they used to :(

Not a stirling is a vacuum engine
