Photo-voltaic's don't have to be a complete solution in order to be a

the
most cost efficient car you could possibly own? Is it as cheap as
taking mass transit? If not, then I guess using a car for
transportation isn't economically feasible.

The ROI on my car is quite good, actually (something like 2,500%). It
allows me to go to work every day.

You just failed basic economics - Very badly.

Photovoltaics suck for the average home. On the other hand solar
powered water heater and direct heating of your home with solar energy
can be very efficient. One study on using photo cells to power a home
failed miserably. Trees had to be cut away so light could get to the
solar panels. This increased HVAC usage by more than the solar panels
could provide. Im not sure which university performed this test but it
was in Fl. Shouldn't be hard to find if you want to look it up.

I think you just made that up.

Why, because YOU didn't think of it? You are SUCH an asshole!
Even at 70 psi, you *should* be able to power that bicycle air horn with yer
ass....

"TRUE" or not, jimmie's post raises a very inneresting point about
trees/shade, etc.

Did you google thoroughly to assure yourself that jimmie's assertions were
NOT true?
Or is jerking yourself off *and* typing with the other hand too slow?

PV's *can* be used to effectively power a home, but it's not trivial, and
it's big total $$, not just for the PV's, but for the surrounding
infrastructure -- batteries, inverters, grid tie-ins, wiring, roof
installation, you name it.
Ditto windmills.

Also, ito the green factor, altho PV's would appear to be idyllic, it's not
well known that the manufacture of virtually all solid state stuff is one of
the most chemically insidious processes in manufacturing, definitely
non-green.

Which is why all this stuff is made overseas, where the rivers literally
bubble from pollutants.
