[amsat-bb] Solar powered mobile satellite operations

Here are a few more solar factoids (for your mobile satellite operations):

The solar panel area to fully power the average American commuter car (EV)
for the average 12,000 miles per year is about 150 sqft (a 3 kW array)

Amazingly, the area of a typical car parking space is also about 150 sqft.

So all one needs to do is cover their car parking space with solar panels
and have free local transportation energy for LIFE.  And amazingly enough,
each car in America has at least 5 parking spaces for it.  One at home, one
on the street, one at work, one at church, one at shopping and sports
venus, etc... so  all you need is just one to be covered in solar panels
and we have carbon free local  transportation (12,000 miles a year for free
and for l life).

In addition, The supply chain from the roof of the carport (also providing
shade to the car below it) is about 30 feet and is over 85% efficient, and
you own it and no one can take it away or change the costs on you at any

Compare this to the 8000 mile supply chain from oil well to your gas tank,
where there are dozens of risky greedy players in the middle and where only
20% of the energy actually gets to your car.

So it is no coincidence that now almost every car manufacturer is seeing
the light and is now building an EV (there are over 30 on the market
now*).  They may not be advertising them because they make higher profit
margins on selling gas cars to gullible buyers, but they are positioning
themselves for when consumers wake up and also see the light for their
local transportation needs.

BMW has already said that all of their cars will be electric (or hybrid)
within 10 years.

For  your mobile satellite station, however, this does not say to cover the
roof of your car with solar (unless it is a flat RV or van) because the
mobile satellite station is only in use about an hour a day while the
parking SPACE with SOLAR panels is operating sun-up-to-sun-down and flat
panels cost only 10% of ones that can bend a little.  Plus the full
dimensions of a "parking space" is actually  more than 10 times the surface
area of the small center portion of the roof of a car.  So the cost
effectiveness of solar on the car is about 10% of 10% or about 1% the
effectiveness of having them on your car port.

Besides, keeping the roof clear for antennas is more important anyway.
