Here's a video showing a seebeck unit powering a video player using heat from a catalytic converter.


This video talks about an idea that is very similar to what we have discussed in previous steps. We think this is great, but we think we can do better.

Catalytic converters are already pretty efficient. They need to warm up in order to operate at full efficiency. If we attached seebeck units it may draw away heat needed to warm it up. So lets just let them do what they do best (reduce toxicity of emissions).

Our idea is to attach seebeck units to the exhaust manifold. By placing the seebeck units on the manifold we get the hottest exhaust region. More heat differential means more electric power generation. Also being inside the car would protect it from the elements.

With future improvements, we would like to have seebeck units in a flexible strip. They could be wrapped around exhaust pipes and then perhaps the technology could replace the alternator entirely, even free up some HP for the engine.

It's too soon to tell without some more testing.

Note: Although these units are very rugged, they are unfortunately not bullet proof. We recommend making sure the cold side is cooled for best results in efficiency and protection of the units under extreme conditions.

Hi,

Have you thought about using it to generate hydrogen and oxygen and use in hybrid vehicle?
