## maximum power

I read somewhere there is a limit to the maximum power a system can have. If this is the case, how does it apply to a black hole? Is there enough mass in the universe for a black hole of sufficient size to swallow this amount of energy, if there is what would happen?

I've never heard of such a limit. Not a theoretical maximum for everything anyway.

Now, some things break down if they have to much.

3. The maximum energy available in the universe is a very large value, but it is one which can (and has) been estimated; if all that energy were concentrated upon a single proton that would represent the maximum temperature possible.

I have seen this vast amount of energy estimated somewhere but I can't find it atm(sorry); but I believe that even such a vast amount of energy would only deepen the gravity gradient of a black hole.

4. There is a limit on the amount of power a system can deliver to the "load", or energy sink. That is determined by the output impedance of the source and the input impedance of the load -- they must both be equal for maximum (i.e. the upper limit of) power to be delivered.

This applies to electrical, thermal, and mechanical systems. "Impedances" are defined for all these types of systems.

Got to make this short, training day today and I'm late.

P &lt; C^5/4G
or

ie 9.1 x 10^51 watts

Thats the quoted formula and result.
