Some time ago on JJJ Dr Karl
mentioned the theory of zero point energy where in a vacuum matter and
anti-matter pop in and out of existence... potentially generating huge
amounts of energy. Would anyone know anywhere I can look to find out more
about this??

The energy has to be paid back in
10-34 divided by the amount of energy, seconds. So the more
more energy the faster it has to go back to the vacuum.
Scientists
are doing their darndest to see if they can violate the laws of physics
(in which case they would no longer be laws) in order extract energy by
this effect... however there is no evidence as et to suggest that these
laws are incorrect, so there is no reason to think that they will succeed.
However, it would be un-scientific for that to stop us from at least
trying in ways that we hadn't tried before (as opposed to trying to make a
perpetual motion machine from magnets, pulleys, ball bearings, and rubber
bands).
We still need to be spending most of our research money on
things that we know DON'T violate the laws of physics, like solar
photovoltaics, solar thermal, wind power, etc., etc.

You forgot solar hot water
again! It really is the Cinderella of this energy debate. If only we
could turn it into the Pamela Anderson of energy sources. Make that the
Princess Caroline, or the Sophie Rhys-Jones, maybe.
Somebody should
get a research grant to find out why some electrical engineers in high
places think that the energy collected from a flat plate (thermal
collector) solar hot water unit will NEVER repay the energy used in its
manufacture. I was told this astounding "fact" only yesterday.
A 4
m2 solar collector can save 4000 kWh per year. This is 1000 kWh
per square metre per year, all collected with a square meter of each of
these:
- a sheet of galvanised iron
- a layer of rockwool insulation
- a sheet of copper with copper pipes soldered to it
- an air space
- a sheet of low-iron glass ( preferably toughened for
Sydney-siders)

Embodied Energy (click for full article)
How
much energy does it take to make all the components of a Solahart solar
hot water system? How long will it take to recover that energy by using
a Solahart system?
The answer is about eleven months, based on
the Sydney, Australia climate and an average family using a Solahart
BCXII model.
The embodied energy of a gas or electric water
heater is never recovered.
It seems Solahart is
even putting the tank embodied energy into this calculation! BTW, this is
not an endorsement, mine is another Aussie brand of solar water heater, or
Nuclear Fusion Primary Heat Exchanger as I prefer to think of
them.
