Rubberband Heat Engine made with acrylic glass

Would the motion be steadier if you used a weaker lamp?

try getting a mirror behind the rubber band engine and for more energy put black tape around the edge.

i think a stirling engine is a better way of transorming heat to make kinetic energy

hey dumbo mabye if you spin it the other way

[mkzhero]

Too bad its has such poor potential.. I mean rubber bands that get near heat dry out and breaks very fast.. The faster you want it to go the more heat you need -the more heat the smaller the life of the engine.. Makes it pretty much usless ha?

Does it work with one side in the sun ?

[calmatosport]

i think you better could have taken black bands, they will absorb more heat

[checkmatedeepblue]

I think it's good idea.

I agree, installing alternating black and white bands or fins will cause the rotor to spin, even in the sun.

how dose it work

[checkmatedeepblue]

contracting of the rubber bands induced by heat of the lump makes it works.
