Stirling engine to electric motor

In summary, the conversation discusses the use of a stirling engine to power a generator which would then power an electric motor in a vehicle. However, the low power to weight ratio of stirling engines is mentioned as a potential challenge. The idea of using a large metal sphere with high heat capacity is suggested as a solution, but the efficiency and simplicity of the layout are also highlighted as potential advantages.

Does anyone know what stirling engine could be used to power a generator which in turn powers an electric motor? I am thinking of using this concept in a vehicle.

A diagram is here:


It shows a metal sphere in vacuum sealed container. It would be connected to by a retractable contact, which would power a generator, which would power a motor.

Sure. The difficulty, though, is that sterling engines have a very low power to weight ratio, so you won't get much performance out of your vehicle.

What options do you know of?

I am aware of constraints for stirling engines. That is why the metal sphere would be large and made of metal with a high heat capacity. Regen braking might be a consideration, but this already enough of a challenge as it is. Hopefully efficiency of stirling engines and electricity and the simplicity of the layout should yield nice results.
 

Related to Stirling engine to electric motor

1. What is a Stirling engine?

A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas at different temperatures. It was first invented in 1816 by Robert Stirling and is known for its high efficiency and low noise levels.

2. How does a Stirling engine work?

A Stirling engine works by using the expansion and contraction of a gas (usually air) to drive a piston, which in turn drives a flywheel or other mechanical device. The gas is heated and cooled through a thermodynamic cycle, and this temperature difference is what drives the engine.

3. What is the difference between a Stirling engine and an electric motor?

A Stirling engine and an electric motor both convert energy into motion, but they do so in different ways. A Stirling engine uses heat to create movement, while an electric motor uses electricity. Additionally, a Stirling engine is an external combustion engine, meaning the combustion happens outside the engine, while an electric motor is an internal combustion engine.

4. Can a Stirling engine be converted into an electric motor?

Yes, a Stirling engine can be converted into an electric motor by attaching a generator to the flywheel or other mechanical device that the piston drives. This allows the motion created by the Stirling engine to be converted into electricity.

5. What are the advantages of using a Stirling engine to power an electric motor?

There are several advantages to using a Stirling engine to power an electric motor. These include high efficiency, low noise levels, and the ability to use a variety of fuel sources, including renewable energy sources such as solar or biomass. Additionally, Stirling engines have fewer moving parts and require less maintenance compared to traditional combustion engines.
