Ammonia engine generator

http://solarandthermal.com/311_aeg.htm

he hot ammonia vapor powers the engine which turns the generator.

The engine is a radial piston design with a vertical crankshaft. Each cylinder has a compression ratio greater than 60:1 The valves feature continuously variable phase and duration, on both intake and exhaust. The engine operates on the pressure of the hot gas, and both the sensible and latent heat of the hot gas. The speed of the engine is maintained constant by anticipatory algorithms. Control inputs include: gas temperature and pressure, weather, clouds, date & time of day, climate models, system details. Monitored outputs: rpm, torque, voltage, current, power-factor, electrical phase, fluid pressure, noise, vibration, system response. The mechanical components of the engine are robust and designed for 20+ year lifetimes. Friction losses in the engine have been reduced to exceptionally low levels. Engine Specifications:

Materials: Forged Steel alloy crankshaft and rods, Cast Iron block, cylinders, heads, Aluminum pistons, Fluoropolymer friction components. Dimensions: (Engine only) ~ 40in dia. x 11in thick (not including manifold pipes, shaft extension, flywheel, oil pan, etc.) Weight: ~ 480 lbs (engine only) Cost: $2.00 / Watt -- inclusive in system price. Generator Options:

All generators we use comply with NEC and UL ratings for safety. We match the generator capacity to the peak system power. We select a generator that has the required voltage ratings to match your utility service or isolation transformer ratings. Special generators optimized for motor starting, lighting, power-factor correction, etc, are available at customer request. Insulation ratings can be varied if the customer desires. Cost: $2.00 / Watt -- inclusive in system price (optional features priced according to OEM schedule) Sample pictures from SolidWorks. Click on a picture for a bigger view and more information.
