Dammit, a CYCLIST will expend some 20 MJ in 300 miles. Recharging
that in an hour needs 6 KW! There is NO WAY that you will design a car
to be as efficient as a cyclist, despite the motor lobby propaganda.


Well I dunno about cyclists. My figures were for about 50kWh (180MJ) for
the 300 miles. And those figures are borne out by other test sites I
found - no I haven't got them to hand because it arose in another
discussion elsewhere. Might be able to dig them up if you are
interested. ireckon a cyclist ambling along at 15mph might need about a
horsepower.. 750W - and would take 20 hours. That's 15KWh or 55MJ? yeah.
within the same range as you. For a back-of-the-envelope calculation.


What ??? I can't imagine a human being able to develop a horsepower
for very long at all - more like 100 or 200 watts and even that would not be
sustainable for long. So how does the average "regular" cyclist ride a bike for
an hour or so at 15 mph covering 15 miles ?
