Made a simple engine. Working on a somewhat larger scale one. Want to make it effiecient and solar powered with lens / parabolic mirror .. Gonna try the "ferro fluid piston" in aluminium cylinder. Thinking about glas regen tube (big test tube) and aluminium scrap from a late cooked in old oild to make it black zo it wil asorb more of the sunlight. Cheerss.
Have you thought about using a higher density non-magnetic coating inside the aluminum tube such as a possible Graphene coated piston to create an absorber to the magnetic differences so that the resistance is negated?
A comment about your idea of "ferrofluid piston": There will be eddy currents on conductive Al tube (resulting an opposite magnetic field) when moving the magnet piston. It will slow down your piston down. You can find it out by moving/dropping a magnet in any aluminium tube and compare movement to non-conductive tube to find this out. Idea might work if you make a static magnet field around aluminium cylinder with ring magnets and try to keep ferrofluid inside the tube. Good Luck!
@358Eki Hey , thnx for the input ! I already found this out the hard way :) I knew about eddy currents, I "though" this ould not apply as alluminium is an diamagnetic material. But hey, it conducts great ..
Currently in the clinch edditing or converting nokia mp4 to make a youtube vid aboout my first misstakes.

@BIC0Gannick0Bic
as i want to go cold I might use liquid oxygen instead of of ferrofluid.
The cylinder then probably will be glass.
