"Move over Golf, how about a VW home power plant?
Like its cars, can Germany's smart grid network of Volkswagen
mini-generators win over Britain?"
Move over Audrey II, this is a real power plant.
"The system has the backing of the German government, which is pushing
Lichtblick’s model – and a similar venture between Honda and meter maker
Valliant – because it thinks switching to decentralised power units will
make it possible to shut down its nuclear reactors by 2022."
Steaming great dozy muppets.
Lets take out zero co2 emission plant and shut it down in favour of a
hydrocarbon based one even less efficient than any other we already have!
About the only thing they have in their favour is they can be used to
try and balance a grid made unstable by all the massively expensive and
Your usual drivel. Still living in the Lala land of the past.
You can't get your head around a new concept can you?
This has been on the cards for years. They will only operate at times of
peak demand and low electricity output.
There will always be a need for gas fired plant, this is just
microgeneration and is more efficient in that the power is used locally and
the heat in the home.
The idea works perfectly because home heat is needed in Winter when PV power
output is down.
All part of the Smart grid" system too.
It will come to be the standard instead of gas boilers.
Nuclear power is finished in sensible society. It always was a false path,
invented as byproduct of the nuclear weapons program. Inefficient, expensive
"Since May 2014, LichtBlick has been unable to offer any more 'ZuhauseKraft
werk' combined heat and power systems. LichtBlick had developed this innova
tive technology together with Volkswagen since 2009. Unfortunately, we were
unable to reach an agreement with VW as to the commercial future of the bu
siness, something we would have really liked to have done."
Oh well, throw some more Brown coal in the boiler Manfred
You were doing so well (reasoned argument) until you spoilt it all in
that last paragraph.
It's true that the current crop of nuclear power stations have been
cursed by the Cold War legacy but there remains the undeveloped LFTR
technology, first looked at by the military over 40 years ago as a
potential means of keeping a fleet of nuclear bombers aloft for weeks
at a time until the penny dropped regarding ICBM technology refined
from the V1 rocket program by Germany towards the end of WW2.
I suggest you goggle LFTR before you discount nuclear fission power
as the immediate solution to the world's energy crisis for the next
300 to 10000 years.
I had to google "FIT payments" (I'd seen it before but couldn't
remember the context) and landed up on this page:
Just out of interest, I tried the calculator using 'ballpark figures
of 8KW generator head running an average of 8 hours a day during the
'heating season' to give a total annual generation figure of 11680 KWH
which. at 75% export produced a total income and savings figure of
No wonder you urged me not to make Harry sad!
However, since governments worldwide are unlikely to percieve nuclear
as the new incredibly safer greener way to both power and save the
planet for at least another decade or two, I don't think Harry has too
much to worry about just yet. :-(
In the meantime, micro CHP seems to be a 'No Brainer' solution to
replacing a >25 years old CH/HW boiler that's come to its end of life.
If I've interpreted that £2,200 figure correctly, I'd be looking at
an effective ROI payback period of just one or two years. Just how
much does a 2 litre petrol engine from a scrapyard cost these days?
Honestly now, anyone got any idea? Also, more to the point, how much
would an 8 or 10 KW genset head cost?
Anything from £1200 to £5K ...
Mind you the generator might not be the one that you'd want to run 24/7
and the engine might be a tad more noisy that you'd like to run at
There is an element of some sense in the idea but I reckon you'll still
need a mains connection one way or the other..

Uur set burns about a litre of (red) diesel per hour, so approx
80p/hour. A litre of diesel contains about 10 kWhr of energy. I doubt
our peak load is a kW so overall efficiency is <10% and thus p/kWhr
is well over 80p. Purely from the cost POV it's not something that
one would use without good reason, like no mains.
And what did harry say? Oh yes "There will always be a need for gas
fired plant, this is just microgeneration and is more efficient in

OK not recovering the waste heat but being a diesel it doesn't
produce that much waste heat. But even if the heat was recovered,
pushing efficiency to a generous 30%, that still about half that of
It's always been obvious that renewables + energy storage would be pretty
nifty, but without storage not a lot of good.
Just possibly, by pushing it all down to the individual level,
something can be done to improve the situation before Putin (or
whoever) turns off the taps.
I see a lot of firewood logs stacked in city centre basements; maybe
some think a problem is already developing.
You can exist (I won't say live) with 4 watt LED lamps turned on only
when a sensor detects a human presence in the room, you can look at the
internet via a Raspberry PI and a tablet, and two or three layers of
clothing and a cap on your head will allow existence without heating.
(Your wife will leave you for someone with more purchasing power, but a
40 watt electric blanket will make up for the heat loss at least, while
other expenses might even decrease :-).

I'd hope to be paying the lower figure for a 4 pole 1500rpm 50Hz
I've got a suitable basement location. It's where the existing Mexico
Super 100 boiler lives at the moment. Obviously, I'm planning on
running the engine at a nice sedate pace of1500 rpm inside a suitable
soundproofed enclosure. It's literally only meant to replace the
function of the original boiler. The 20% surplus electricity is going
to be dumped into the mains supply connection.
Basically I'm turning the current boiler's 79.2% efficiency (20.8%
loss) into high value electric energy (turning the efficiency equation
on its head so to speak).
There'd be no sense at all in running a micro CHP generator _without_
a connection to the grid otherwise you're going to have a problem
storing all that surplus electrical energy - the grid makes an
excellent storage facility.
From the viewpoint of the PSUs, it's far less problematic than home
PV generation since it contributes to the grid during peak demand
periods rather than during low demand periods. The mains gas
consumption remains pretty well unchanged eliminating the "Robbing
Peter to pay Paul" factor.
I expect this type of co-generation would be favoured the most by the
PSUs but they don't have any say in this and it seems the eco green
bollocks has decreed that the FIT rates be the least favourable of the
lot for CHP.
