Re: [EVDL] Free EV Solar commuting for life

That is a start.  However the super edgy 4 passenger cars of the World Solar 
Challenge should be the paradigm with 1000 km range.  However a compromise is 
always made.  Heavier weight and less range but a 15kw battery pack is easier 
to charge than an 85kw pack...and a lot cheaper.  The future is on the horizon 
but what will be accepted is not yet known. It is solar & it is electric.  That 
much is known.  Lawrence Rhodes

Yes exactly, but that is why the Prius was such a perfect match for this
display.  Its full charge useful range is 12 miles (on all electric) and
it does charge (like any EV) at 12 amps from 120v (1.5kW) and can fully
charge in 4 hours.  So I matched that up with 1500W of solar panels (6)
and that is the basis for the claim.

So, as a baseline, 6 panels lets say gives 12 miles a day which covers
about 52% of the national average of commuters.
Up that to 12 panels is about 25 miles a day which covers 85% of all
commuters in the USA.
Up that to 20 panels and you get 40 miles a day which covers 95% of all
americans daily travel?

Humh.  So I guess the figure to remember is 2 miles a day (for life) per
solar panel (now under $200 each)... that's in Maryland.  If you lived in
Arizona, that would be more like double that.

That's well done, and certainly provocative.  I like the way you promote EVs 
publicly.  

Still, how many Prius owners plug in?  The vast majority of Prii on the road 
don't have plugs at all and run 100% on gasoline.  So I'm afraid that most 
Prius owners will look at that and think "Huh?  What's that all about?  I 
don't need to charge my car."

And even if one happens to be among the few with a factory plug-in Prius, 
his or her PIP can only go 6 miles (EPA rating) in EV mode.  

Maybe more to the point - how many panels like that will it take to charge a 
Leaf or other "real" EV every day?  Doesn't that depend on how far you drive 
anyway?

It's a good idea and, as I say, provocative, but I wonder whether the Prius 
is the right example to use.
