I've been thinking of taking some 2 inch drill pipe to make into adriveline for my s10. At which time I would like to take some 3/4 to 1 inch steel pipe to cut in halves to use as 1 inch wide fines for a air turbine to drive the driveline under light loads like cruising on the highway, or regenerative braking around town!!
For the compressor part I'd like to offset two 4-6 inch wide rotor type compressors!! Looking into it I could by a couple feet of different size pipe and weld this together pretty easily!?!
