Nuclear keeps the working population tied to a safety corrupt, profit-
seeking power supply company.

Nuclear is slow to build and there is still no answer to radioactive
waste, accidents, volcanoes, tsunami or earthquakes.

Nuclear uses vast quantities of concrete which is one of the most
energy wasteful building materials. The "lag" before "clean" energy is
actually produced means that nuclear is CO2 dirty until it clears its
total, carbon debt.

Nuclear is an incredibly easy target for determined or ruthless
enemies. You can't harden it against all risks. Like a single
terrorist and a plane full of fuel. Or a single missile. Or even a
hand-held rocket launcher. Even if the attack doesn't release
radioactivity it will easily kill output via cabling or local
transformers or critical pumps power supplies.

Overhead power cables are incredibly easy targets since they cross the
open countryside where guarding them against even the most amateur
attacks would prove totally impossible. One man with a shotgun or a
rifle could take out critical insulators with pocket money munitions.
One pylon destroyed is a critical loss of power to vast areas of
population and commerce. Nuclear seems incapable of being hardened
against cyber attack unless completely isolated from the internet.

Micro solar, wave, water and wind power are some of the most difficult
energy sources to destroy en masse. They require no connection to the
cabled network unless demanded by the state or system profit seekers.
Throw one switch and the system can be isolated from the network and
continue producing abundant local energy. Cable losses are almost
nil.

Overnight wind charging of electric cars makes a lot of sense. Petrol
driven cars use a vast amount of energy globally and make us dependent
on oil. Nuclear won't change that one iota. Charging electric cars
with nuclear at the end of a long overhead cable is incredibly
inefficient. Centralised electricity production used to be quoted at
well below 10% and even below 5%. Overhead cabling is also highly
weather sensitive and high maintenance.

Tomorrow's war will be highly asymmetric. Islamic sleepers, hiding in
the general population, will simply be pinged and make suicidal
strikes which will cripple energy production with ultra-low cost,
local but crippling attacks on the national power network.

Armies and navies are already completely redundant unless the enemy
chooses to fight on your terms. Why should they bother if it means you
have clearly superior forces?

Fortunately, though, there is a third choice. The "greens" may not
like it, but I don't care about what they like. I only care about
global warming because it's real.

The following concept has always intrigued me... it seems so
logical...
