Very interesting this linear thermoelectric generator, but too noisy for my taste.
I also thought me a kind of linear Stirling or the piston and the displacer are mounted on springs. The displacer is driven electrically at its resonance frequency, therefore little energy consumed. The movement of the piston then would generate current through a generator, I put the project poses after failing to find an effective way to generate power from a slow linear motion (displacement 2cm approx. 30Hz ).

For now I have a thermoelectric project much more modest: a fan for wood stove. I will not bother with a Stirling engine, I'll just use furriers modules and an electric motor, as many others have already done (see youtube).

Thank you for the info I had not seen him like this




Question: Are we forced to put a battery system behind the Stirling generator, impossible to directly connect a 6 Kw alternator and "shoot" directly (washing machine, dryer and dishwasher) without stalling the Stirling.

hi chatelot16
In our case,
the generator is not only linear but also the Stirling!

Couldn't a spring convert kinetic energy into the "limit switch of the whole system?"
and compete with the connecting rod.

Stirling rodless (involving more than pistons) would not it be easier to make?

the crank rod system does not only recover the energy at the end of the race and give it back to launch in the other direction: it fixes the race with precision: one can make arrive the piston near the breech without risk of shock

the spring can recover the energy but does not stabilize the race: it takes a very inteligent regulation system not to break any

to store the same energy a flying is cheaper than spring

a steering wheel has no lifetime limit ... a spring tiredness, fewer be largely oversized has a limited lifetime

More interesting and cheaper than industrial stirling for a longer service life: you take 10 modules (total 220w) for approximately $ 600.

no longer on life: many reviews for this type of product gives a high degree of breakdown and high temperature is fragile.

Hi,
The Stirling engine and linear alternator fitted to some Viessmann boilers do not seem to use spring and is not noisy.
It is a brand that treats its robust reputation.

A Stirling engine silent and maintenance free

The Stirling engine is sealed, works silently and requires no maintenance. Thanks to these qualities, it can be installed near the house.

The Vitotwin 300-W is particularly economical with a gas consumption of at least 20 kWh and an electricity consumption of more than 00 kWh per year. That is to say the equivalent of the needs of an existing average single-family house.
It was announced to produce between 0.6 and 1 kW of electricity.

By "electricity consumption of more than 3000 kWh per year" we should read production, I think.

to reverse the movement of a piston end position if there is no link it necessarily be a spring but not necessarily a steel spring, it can also be a gas compression in a cylinder that has a big advantage on the steel spring: the gas will never break through fatigue!

Integrated in a boiler, it is that same progress as the engine heat losses are no longer as used for heating and producing hot water.

This is not the case either.
