	:*'''Worst case scenario from calculator is 0.02 rolling resistance, 16 sf frontal area, and drag coefficient of 0.6 - which still gets you to 22 MPH with no engineering required. Just by using mountain bike tires, open cab and no aerodynamics - 1kW of solar + pedal power gets us 22mph. With a 1 kWhr battery pack, we still get 30 mph. Thus, solar NEVs (solar neighborhood electric vehicles) are completely feasible. With an on-board 1 kw generator - we get 35 mph at a total of 3kW of power. When designed for aerodynamics and drag, we get 65 mph in this case.		:*'''Worst case scenario from calculator is 0.02 rolling resistance, 16 sf frontal area, and drag coefficient of 0.6 - which still gets you to 22 MPH with no engineering required.
