• The Volo One Engine Is Available For Purchase!

    The Volo One Engine is now available for purchase!

    After 2 years of development we are ready to move into the production phase.

    The Volo One Engine runs off of heat, when there is a temperature difference (roughly 400 F) from the cold end of the engine to the hot end of the engine.  For example, you could put the head of the engine in a bonfire and it will run (not that you'd want to put into a bonfire).  The Volo One Engine is not a steam engine.  The Volo One Engine runs with low pressures and relatively low temperatures compared to a steam or internal combustion engine. This makes it inherently safer then steam and internal combustion engines.

    The engine was designed to be used to generate clean electricity using wood, propane, natural gas, waste heat or any other heat source.

    The Volo One Engine is big (8' long) and heavy (250 lbs) but elegant and beautiful at the same time.

    We've brought this technology into the present, with new materials and modern day tooling to re-invent a stirling engine that can produce real work (1 KW ).

    The Volo One Engine today is configured to run with heat produced from either Propane or Wood front ends (i.e. what creates the heat for the engine). The engine can run off of any other type of heat (less then 900 F) that you may design.

    We are working on a solar front end, it is under development but not yet ready for sale.

      Dear Tim,

      We are a new start up from India.

      We want to have a 1 KW Stirling Engine which is running through 100% Solar Energy Only. We do not want any type of fuel to be used. We can allow a “thermal battery” for 24*7*365 Days base-load operations. Solar Concentrator is OK. The engine should generate 24 Units daily. Out of 24 Units, 5 Units will be consumed by House, remaining units will be used to produce pure, 99.999% hydrogen by water electrolysis through Nanoptek Corporation, USA Solar-Hydrogen Panel which generates 1 KG Hydrogen by consuming 16 Units of Electricity.

      The Pure Hydrogen will be used as “Cooking Gas” through a modified Gas Cooking Stove.

      We will give this entire system to poor, below poverty line people in India and in Other Countries. We will take only rental for this system, The Rental will be 5 US$ Per Month.

      This system should not be very big in size.

      It should be small so that we can put it on Roof Top.

      Can you supply such system??

      We will need 30,000 such systems in 1 Year after successful pilot project in India.

      Hi Harold,

      1) Price – as listed on web site.
      2) Power – Between 100Watts and 1000Watts – dependent upon pressure and temperature environment that you run the engine in.
      3) Shipping dimensions – we ship in 3 crates, each about 36×36×36.
      4) Maintenance costs and frequency – this is still being determined but looks like – seals will need to be replaced 1/yr at a cost of maybe $50.
      Other wise the engine should be maintenance free for years of operation.
      Greasing of bearings and maintenance of generator fan belt will need to be done as needed.

      Let me know if you have further questions Harold.

      I pray you and yours are Blessed!
      1. Price & availability?
      2. How much power can it produce?
      3.shipping dimensions?
      4. Maintenance costs/frequency?

      Best Regards
