Could such a marvelous device run the CPU itself? |
|

I note that you say 'useful' energy. Explain. |

Electricity is useful, no? |

I use that heat to warm my feet. |

|
| |
In remotely worthwhile quantities, yes. |
|
| |
The heat could power a fan, which would be just as effective as it needed to be to prevent its own activation. |
|
| |
Atom doesn't need a fan; it already sucks. |
|
| |
Yes, but if I'm gonna pay hundreds of dollars for something, "normal usage" is the last thing it's gonna see. |

Simon, anything you put in which is extracting useful work from the waste heat stream is going to increase the thermal resistance of your cooling system (read:push the temperature of the source up). |
|
| |
A CPU, at any given operating point, will produce a fixed thermal output power. The thermal resistance between the source and the surrounding air determines the temperature difference required to push that amount of heat away from the chip. |
|
| |
If you put a turbine on, as a rough estimate, the exhaust temperature of the turbine will be equivalent to what the exhaust temperature of the heatsink would otherwise have been. The inlet temperature of the turbine will be hotter. The CPU will therefore be hotter than it would otherwise have been. |
