Hi Endless Sphere,
I would like to present here my design for a compressed air engine that incorporates regenerative braking. I designed this engine almost 20 years ago. I would eventually like to build a proof of concept prototype. The design is open source, and is explained in the attached pdf. There are many aspects of this project that the Endless Sphere community can help me with. Just to start with, 1/ Complete the 3D cad model and select engineering materials and components, 2/ Model the thermodynamic process of the engine, 3/ Build and program a microprocessor to control the engine. To preempt some, the energy density of compressed air is about 30kwh/ton or 30wh/kg, and I am not bothered that your Tesla battery does a bit better.
