Energy Conversion: How to Convert Heat to Electricity

AI Thread Summary
Heat energy can be converted into electrical energy using thermoelectric devices, such as Peltier junctions, which exploit thermoelectric effects. Photovoltaic cells can also be utilized, with some designed to operate in infrared wavelengths. Additionally, paramagnetic refrigeration is mentioned as a method that involves manipulating heat at a molecular level. The discussion emphasizes the potential of various technologies for efficient energy conversion. Overall, there are multiple avenues for converting heat to electricity beyond traditional methods.

Hi,

Is it possible to convert heat energy into electrical energy. (Excluding boiler engines, ect...) Following along the lines of capacitance and capitors...

Thanks.

Peltier junctions (thermoelectric devices) do this:

Edit: Actually, it might be more accurate to describe a thermoelectric device as exploit the http://www.autobahn.mb.ca/~het/energy/pv_fqa.html#Section02D , rather than the Peltier effect.[/color]

What about photovoltaic cells?
 
Are there PV cells that work in Infrared wavelengths?

Also, I will mention paramagnetic refridgeration, a technique used to cool things towards absolute zero by letting heat flip little magnetic dipoles.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
