Steam Engine Specifications

Summary:

• Deliverable: a one cylinder prototype with scalability as above, to constitute a single stage of a stageable system (compound or 3 stage)
• System consists of cyliner, crank arm, mechanical valve, automatically adjusted cutoff ratio, and constitutes a Steam Engine Construction Set
• Applications to stationary, mobile, and solar power

Cost-Related Features:

• Lowest materials cost for a given performance
• Simplest to fabricate, therefore lowest fabrication cost
• Advanced techniques of fabrication utilized only when necessary to achieve cost
• Fabrication tooling preferably simple, but secondary to fabrication cost
• Uses commonly available parts
• Replicable
• Materials cost of $50/hp

Materials calculations:

• 20 pounds of weigh per horsepower

Flexibility and Performance:

• Scalable in power output from 1 - 100 hp by
• Power density of 1 hp/10 lb
• Pressure up to 500 psi
• Scalable cylinder dimensions, uncoupled staging, and tandem operation allows scaling of power and eficiency from 1-100 hp and up to 25% efficiency
  • Multiple cylinder, in-line configuration is possible by bolting several cylinders together

Lifecycle
