you know many of these arnt so useless. A power that is useless is something you dont want cause its useless, and btw the definition of power is energy/(time unit). So what I have to chose is an energy/second that is useless I guess that would be a power of h/Ï€ wich is an energy of the size plancks konstant divided by pi seconds, wich is a power of the size
((6.626068 × 10^(-34))/3,141592653589793238462653383279)Watt
(with as many decimals on pi I can remember for the moment)
I think its a smal enough number and it contains two beutifull constants.
And you know what I have this power and more at that LOL ;)
