Micro CHP (Combined Heat and Power)

Boiler with STIRLING engine with the best value for money: the 5 version of whisergen: the Mark 5 (made in New Zealand) and basically the new European version that is manufactured in Spain, the EHE (Efficient Home Energy).

micro-cogeneration, condensing boiler; 102% yield:
Stirling engine 4 cylinder type siemens double action with its burner;
Electric Power: 1000 W AC (to 220-240 V)
Thermal power: from 7,5 kW to 14 kW
Fuel: natural gas
Dimensions: 491 * 563 * 838 (l * p * h) instead of a dishwasher
Weight: 148kg
Certifications: CE Certificate


Official site http://www.whispergen.com/

It runs on gas only so I do not quite understand the interest of making a stirling (more expensive) rather than using a small engine GNV (modified diesel base) higher efficiency and much lower cost ... the noise can be?

Not bad the "shifting" kinematics of the crankshaft: http://www.whispergen.com/content/libra ... ergen.html

The real need is for this cogeneration to work with wood pellets: with gas, we continue to consume fossil energy, and we remain dependent on multinationals, foreign countries, and indexation at the price of oil.

my gazogene will work as well with the pellet of wood as real wood ...

the burner of this stirling is it adaptable to the gazogene gas?


once the wood turned into gas I prefer the good old engine explosion ...

Hello

I dig up the subject which is always interesting

thank you Gregory for this reminder of ownership

On the cogeneration side, and more generally on the energy side, things have changed.

Photovoltaics have become really affordable, and the routing of the surplus, to a hot water tank for example

Cogeneration from fuel oil or diesel or any other fossil fuel seems to me quite useless, especially given the state of the planet (see the conferences of arthur keller)



The idea that I had before all this was this

We start with a car diesel engine for its price and its availability and availability of parts over time
we use one, or two cylinders to make it run with renewable, free, (vegetable oil)
one or two cylinders are used to compress air, for storage, then use with a compressed air motor (basic tool or not)
The heat from the engine is used to heat with the air, and the water from the cooling system

management is done with an Arduino or similar

the inconvenients :

it takes constant maintenance, Madam will not know and will not want to make it work, teenagers either!
The noise, you have to be in the countryside
find free oil
lots of debugging time


Advantages :
Almost zero implementation cost because almost everything can be recovered, especially in the countryside (cars for engines and alternators, storage tanks for compressed air, wiring, ...)
should be considered as a back-up, in addition to other systems
you can use the excess power or electricity to lift a weight or water but you need slope and space ...

This should be planned either as a hobby DIY, or as a production tool in a permaculture farm, but viable, review the conferences of arthur Keller and on the subject.
Conference of April 12, 2019 "Permaculture in the face of collapse" led by Arthur KELLER, Vincent MIGNEROT and Joris DANTHON. The event was organized in Nantes by the Permaculture 44 and Adrastia associations.



There you go, it's a bit confusing, but it gives an idea.

Olivier

Permaculture cannot be improvised in 15 days, let's listen to Arthur Keller, and let's not forget to vote for the program that best defends our interests!

Nice digging up and updating!

There remains another interesting (but extremely rare) cogeneration: photovoltaic cogeneration, in other words, PVT panels: photovoltaic and thermal ... or even hybrid solar panels. The advantage is that we improve the PV yield by cooling them continuously!

solar-thermal / solar-panel-hybrid-photovolthermic-pvt-solar-t7723.html
https://www.econologie.com/telechargeme ... thermique/

But at less than 1.5 € the PV WC installed (at the REAL craftsmen not the profiteers) not sure that the PVT is still interesting ... economically speaking.

Besides, I don't even know if there is still an offer on the market, the 2 links above are already a few years old!

Not necessarily wise to bet on compressed air which requires specific tools, is not as universal as the use of electricity and is done with a lot of losses (losses which can however be bearable in applications where the compressed air brings possibilities that other energy carriers do not have).

Compressed air * is crap !!

If I remind you of someone, it's on purpose!

* as an energy vector ...

Yes, I see more or less who you mean: it was not someone "from nothing" * (and who returned there), by any chance? : Mrgreen:
