Can Aircraft Be Far Behind?

Electric cars will never eliminate our dependence on oil from the middle
east. That is a bold statement and I could be wrong but I believe the
only way to eliminate our dependence on foreign oil, is to use every
possible alternative to power cars and trucks, including bio diesel,
methanol (from something other than corn), natural gas, maybe hydrogen,
and to what I believe will be a limited extent battery power. At the
same time we should stop using fuels to generate electricity that work
well in vehicles so as to save it for vehicles and use nuclear, coal
(which can be made clean with the byproduct useful for making concrete
stronger), hydro-electric, wind and solar (and I don't mean PV cells).

What I can't understand is why solar heat for your house isn't being
pushed more. Unlike solar electric cells, solar heat can easily and
quickly pay for it's self. In many parts of the country it can provide
over 90% of your heating needs. The only disadvantage I can see, is for
it to be most cost effective, you need to have it built into the house
from the start. It's hard to add it to existing homes and have it be
efficient unless certain things just happen to be right. That may be
part of why it isn't talked about more.
