Engineers lately are working on every part of a car to
improve its MPG, they optimize the engine, batteries,
aerodynamic shape, even regenerative breaking
to win extra percents of efficiency here and there
But there's one area of a car where immense energy is lost
Just look at a large parking lot in the summer where
you see thousand of cars baked in the sun for hours
It is the roof! The sun does nothing useful but heating
the habitacle to sometimes up to 125F which ages
prematurely the plastics.
What if designers put some 1m2 solar panel in the roof? It would
silently recharge the battery, equivalent to free gas falling
from the sky. The panel can also charge while driving
The outer panel shape would be convex and smooth so the
wind would see no difference vs regular car.
It would run best in California, Arizona, and sunny states, in
summers when gas is heavily demanded
It could save maybe 10 percent (to confirm),
heck 10 percent more MPG i take it!
So why not?
