I too would be interested in that.

Special report: Renewable energy

Saturday September 2, 2000
Householders could one day be producing as much electricity as all the
country's nuclear power stations combined, thanks to the revolutionary
application of a device developed in the early 19th century.
A new version of the device, the Stirling engine, is set to turn ordinary
domestic gas boilers into miniature power stations, generating electricity
whenever you switch on the central heating or hot water.
It won't make electricity meters run backwards. But for an estimated £500
extra on the price of a new boiler, the machine will generate electricity
for the home for nothing, using excess heat that would otherwise escape out
the flue.
In Britain, a confidential report prepared for electricity companies by
energy consultants EA Technology estimates that by 2025, 13m of the
country's 23m households could have their own little power station humming
away in the boiler cupboard.
The Stirling engine was patented in 1816 by a Scottish clergyman, Robert
Stirling. It consists of two cylinders, filled with gas, each containing a
piston. The cylinders are heated and cooled in turn, making the pistons move
up and down to turn a drive shaft.
In existing domestic gas boilers, about a third of the heat is wasted. With
the latest make of Stirling engine fitted, that spare heat is used to drive
a small generator.
The idea of turning homes into power stations is known as "micro chp"
(combined heat and power).
EA Technology is championing a Stirling engine made by WhisperTech, a New
Zealand company, which can generate a kilowatt of electricity - enough to
power three fridges.
British Gas is working on a different design with a similar power output,
based on an engine from the US firm SunPower.
"We have now got to the stage where we've overcome the technical barriers,
and it's simply a matter of product development, things like designing the
right colour for the casing," said EA Technology's Jeremy Harrison.
He said the first units would be on sale in 2002. Depending on the size of
the home, he said, they would save householders between £150 and £300 a year
on their electricity bills.
The beauty of micro chp is that it cuts in when demand on the grid from
households is greatest. On a summer's afternoon, with the fridge on and the
TV and VCR on standby, a household might be using only a few hundred watts
of electricity.
On a winter's evening, with kettles, electric cookers, irons, washing
machines and tumble dryers working, that might rise to 20 kilowatts. But
with the central heating and hot water on, the home would be generating its
own electricity, lightening the load on the grid, the family budget, and the
environment.
EA Technology estimates that at peak times, a network of 13m households
would generate 15,000 to 23,000 megawatts of electricity, compared with
15,000 megawatts produced by the country's nuclear power stations.
However, if the government wanted to promote micro chp specifically as a way
of cutting down on the carbon dioxide emissions held responsible for global
warming, it would need to close high-emitting coal-fired power stations,
rather than nuclear ones.
The government has been keen to promote chp as a means of implementing the
1997 Kyoto protocols, which called for reductions in carbon emissions.

Having been to the IWA National Boat Show and the Southampton Boat
Show recently, I have seen the WhisperGen in action and can confirm
that it produces about 870W of electricity and about 5kW of heat. This
may be OK in a number of situations but it is quite a large amount of
heat production when you are really more interested in the electrical
power in greater quantities.

Rather than burn the energy for heating, picking a sensible room
temperature, insulating to higher standards and making use of natural
heat energy under-floor and in air-flows, and in the hot-water
calorifier system, will go a long way to reducing your generated heat
needs.

driving a heat pump with a household engine. I presume the expensive
Stirling is required for its low pollution external combustion. IMO the high
efficiency and low pollution of the HCCI (homogenouscharge compression
ignition) engine would be one answer if only thepeople working in this
area were a little more inspired.
