I wonder how much longer Germany could have held out if it's tanks
and planes were 20% more efficient?
The WWII P51 Mustang gained the range needed because it was fuel
efficient. As far as us today, the military has it's own strategic
reserves and in flight refueling. I don't care about the mileage in
In rec.aviation.military we've hashed out WW2 technology ad nauseam.
There wasn't that much difference in technical ability because each
side could examine the others' wreckage and test captured examples.
The big difference was the demands of remote offense vs local defence.
Germany never had more than a small fraction of the US and British
ability to project power overseas, they expected and planned for a
short, local land war. They had more trouble moving supplies by road
and rail across Russia than we did shipping them half way around the
The odd thing about energy conservation is that this rarely benefits
the poor who are mostly about using energy. You need to have some
money to start with before you can think about saving some!
I've worked on that issue and made my house and appliances
considerably more efficient by simple, inexpensive changes like
replacing the shower head with a sink spray that shuts off when
released, drying laundry outdoors year-round, learning to live with a
smaller refrigerator and opening windows to vent with night air
instead of running the AC. I have an antenna for TV and dial-up
internet, which save over $100 a month vs cable.
They seem to demand too much prior planning, attention to detail and
change to accustomed behavior for most people. For example I have to
watch the weather forecast to plan when to do laundry, and calculate
the dew points or comfort index of indoor and outdoor air to see if
nighttime venting is worthwhile when the humidity is high.
