Probe
It's a shade tree mechanics look at an actual 'light' rail system.
The probe,with parallel-hybrid drive,could be the locomotive for very light passenger railcars,festooned with photovoltaics,ganged together to feed the electric traction motor.
*Low mass
*Mass below the floor
*Low center of gravity (seating only,no standing)
*low frontal area
*1/10th rolling resistance if on steel wheels
*Low Cd
*Carries it's own 'fuel'
*'Modular'
*Regenerative braking
*Downhill coasting
*No idling
*Low-to-zero carbon
What would that cost to construct?
What would they have to invent?
What would that cost to operate?
Would tracks and wheels from a children's amusement park roller coaster system not be adequate?
What safe velocity could it operate at without risk to commuters?
