Source for Stirling engine

No.

The Stirlings or Carnot Cycle engines that produce real power remain proprietary. Most devices that are sold are toys, curiosities or at the most able to turn a fan lamely as it sits on a woodstove.

there is a company in Denmark that make stirling engines designed to use waste heat from industrial processes they make systems from 35kw to 500kw http://www.stirling.dk/

YOU CAN USE THE WASTE HEAT FROM FURNACE FOR HEATING THE WATER INTO STEAM AND THEN USING THE STEAM YOU CAN GENERATE THE POWER THROUGH STEAM ENGINE

ASIT SHAH

Without recommending a source for Stirling or Carnot engines, just a small reminder...

It is a very common error to talk about waste energy in your case. If you are using your exhaust pipe heat to generate energy, you are cooling the system at the same rate as you are generating your power. Hence, your furnace will be cooled down and will require more energy to keep it at the required temperature, and so on. No free meal my friend...

Your only true savings will come from improved thermodynamics. It will be your best investment - by far.

I don't think this is a Stirling, but uses the concept you have in mind. This is all I have at the moment, but this will soon be done in homes, industry, and automobiles. The nay-sayers don't haven't done any real research, believe me. I have built one prototype heat recovery system and will be doing more as time allows. The next one will use the energy from my air conditioning and will also work on my vehicles.

I will cut the electricity use on my air conditioning a minimum of 10% and is based on true science not scams. I hope to begin installing retrofit products next summer.

I have saved over $600.00 in the last 3 months alone by making design changes in my home air conditioning system!

Nothing I have done is extreme, overly high-tech, or complex. It is common sense based. I have considered many ideas over the years and not acted because of nay-sayers only to see a product on the market later on, but no more!

Get busy! Do something! Even failures are learning experiences!

"here is a company in Denmark that make stirling engines"

This company does not sell the engine on the open market.

Notice that their home page says "selected partners"

For the size to weight ratio, and probably price, you would do better with a steam turbine

We are not naysayers; the man asked if he could buy a Stirling!

The Carnot Cycle is an amazing concept and the Stirling a wonderful application of thermodynamics. However, because of intellectual property realities the firms that have produce a working Stirling cannot risk that reverse engineering will unravel their work and their incentives.

Thousands of 4 cylinder Stirlings coupled with CSP (concentrated solar power) are producing 25 megawatts of electricity each in the Mojave Desert, in this case with parabolic dishes. But I contend that greater efficiencies can be obtained with parabolic troughs and steam turbines.

We have worked significantly with solar power experimentation since the seventies. The problems have been the realities of power storage for when the sun don't shine The realities also of an inadequate grid that must be able to send electricity long distances combined with difficulties inherent to Direct Current.

Storage of power with kinetic, compressed air, or heat storage with thermal mass (oil and molten salt) has been explored exhaustively. Electricity can only be stored with batteries but unfortunately there have been few significant breakthroughs in battery power. One presidential candidate has even offered a reward for a new battery.

Reverend Stirling's engine was used briefly by industry but was driven into obscurity by Faraday's electric motor and the internal combustion engine. I have been disappointed with the Stirling's power to weight ratio, the lack of compression in the hot end and the inability to operate for significant periods of time without descending in performance because of heat conduction.

Hi corneliusvansany,

As A stirling engine engineer I would say that stirling engines are not used so briefly as you put it!

An Australian company sells a domestic gas biler to produce heat in the home, the exaust heat from the boiler is used to power a 5kw stirling engine to produce all the electricity your home will need!

I designed and constructed my own stirling engine to be placed within a gas boiler many years ago (1986) and it is still in use today.

I also utilised a stirling engine to power my 25ft boat while living in Norway, this engine is still in use today, and is powered by wood chippings!

You will find stirling engines in the most unlikely of places ie, in space, in boats and a variety of other places where oil using engines would be a problem.

Todays modern stirling engines are more efficient than any IC or CI engine today.
