Gas
- 27 hp - $980 - $36/hp - [1]. And needs muffler.
- 24 hp - $870 - $36/hp [2]
- 20 hp - Kohler $700 - $35/hp + muffler - [3]
- 19 hp Poulan - - $20.5/hp - $390 - [4]
- 16 hp - $350 - Poulan - [5]
- 16hp - $330 - Duromax, $20.6/hp - [6]
- 7 hp - $99 - $14/hp - but no electric start - [7]
Diesel
Considerations
- Until an open source engine becomes a reality, engine repair is expensive. $50/hr, easily comes to the new engine price for the $300 gas engine. This indicates that small engines are essentially disposable goods.
- For the large diesel engine, parts are expensive.
- Until the advent of the open source diesel engine, engine costs remain 10x as high as they should be.
- Until the OS engine, disposable engines are a suboptimal but acceptable strategy to keep costs of engine systems low.
- It is an immediate priority of OSE to develop open source small engines, $11B market (see Market Size) and larger ones are more like 200 billion
Engine Links
- Pellet-fired stirling engine buggy - see PDF file
- Several links to various engine types including Sterling, Wankel, Steam, etc. [10].
