Bill:

Your search for a "simple" way to power gear is great. It points out a
lot of what is, and what is NOT possible.

Just powering a little 100 watt rig is not a simple thing, when you
don't have access to a 120v plug.

Your question points out what a joke electric and hydrogen powered cars
are. There are no hydrogen wells and you still have to burn oil to get
the electricity you need to power umpteen electric cars. (yes, there
are windmills and hydro-generators, but they could not produce a
fraction of the power which would be needed if all cars were powered off
electric)

Makes one yearn for a true "zero point energy" source ...

JS

Agreed!�

I'd say it's more about practicality.

btw, the Honda EU1000i generator weighs less
than 30 pounds, is quiet and reportedly well-behaved.
Not inexpensive and you wouldn't want to backpack
one too far, but an off-the-shelf solution.

Just powering a little 100 watt rig is not a simple thing, when you
don't have access to a 120v plug.


Perhaps part of the solution is thinking outside the box.
For example, cutting the power to 50 W reduces the
peak power load by half, but only costs 3 dB. Using
more-efficient modes means QRP can do the work
of QRO.

I disagree - about electric, anyway.

*There are no hydrogen wells and you still have to burn oil to get

Until somebody figures out a way to produce, transport and store large
quantities of hydrogen economically, H2 power
will not make any difference.

The main engineering limitation of electric cars is the battery
technology.

Oil is not a major source of electricity in the USA, however.
As of 2005, US electricity was produced from the following
sources:

Coal 49.7%
Nuclear 19.3%
Natural Gas 18.7%
Hydroelectric 6.6%
Petroelum 3.0%
Other (wind, PV, etc.) 2.7%

The current use of wind and other sources can be greatly
expanded.

*(yes, there
are windmills and hydro-generators, but they could not produce a
fraction of the power which would be needed if all cars were powered off
electric)


There is no one easy solution to the problem of
energy supply, but there *are* solutions, whether
it's powering a ham rig or an electric car.
