NOOOOOOOOOO!

for gods sake do not just grab something semi-round and think it will
work as a flywheel, the day it bursts those who live through it will
regret your lack of engineering rigor.

I cannot stress this strongly enough.

There are scrapyards full of flywheels, made out of an appropriate
material.

You MUST KNOW THE YIELD STRESS of your flywheel material, that word is
KNOW, as in FOR A FACT, as in you have absolute knowledge of the
precise composition of the material it is made from.

Hand on heart, I would MUCH rather take my (minimal) chances standing
in front of a handgun bullet in preference to standing in front of a
bursting flywheel.

80% of those shot with a handgun survive

I suspect, based on prior experience, that there is a much smaller
survival rate among those standing next to an exploding hand
grenade..which is exactly that a bursting flywheel is.

The aim of untold millions is to be free to do exactly as they choose
and for someone else to pay when things go wrong.

In the past few decades, a peculiar and distinctive psychology
has emerged in England. Gone are the civility, sturdy independence,
and admirable stoicism that carried the English through the war years
.. It has been replaced by a constant whine of excuses, complaints,
and special pleading. The collapse of the British character has been
as swift and complete as the collapse of British power.
