Default Aerodynamics of Towing

Cookie...are you drinking enough? The weather in your part of the world
must be bad as you do not seem to leave much time for flying.

This one is for Ian so you others don't read this, OK?

Ian,

I have invented a "gravity powered machine". It uses weight(s) as

fuel.
Once the fuel is exhaused, the "used" fuel is fully recoverable and

can
simply be put back in the "tank", and the machine will start running
again!

Here is how it works.

Take a bucket and place 100 steel balls into it.
Take another bucket and place 100 steel balls into it, but also place

1/2
of a steel ball into it. These steel balls are the "fuel"

String a rope over a pulley from the peak of the barn. Tie the buckets

to
each end of the rope, about 10' high. Naturally the heavier bucket

will
fall to the ground, lifting the light bucket. Remove one steel ball

from
the heavy bucket making it now the lighter bucket. Now the other bucket
will fall to the ground, remove one seel ball, etc. The machine will go
up and down until you run out of steel balls.

But don't worry, just pick up the steel balls and place them in the
buckets again, have fun all day with gravity power!

(Same way a glider is powered by gravity!)

the
real answer.


The sun.

Also, initially, internal combustion engines, stretched rubber or, if
you buy an Electrostart and choose your contract carefully, nuclear
fission!
