If it were the case that Linux had such a defect don't you think it would
have been discovered by others?  I doubt his hardware is so unique that it
only affects his system.

Yes, 30C.  Isn't the whole world metric?

I don't know that it does or doesn't.  But the question is to vague to even
contemplate.  Maybe in a multi-tasking environment Linux is more efficient
in its scheduling.  Maybe a Linux system spends less time in an idle/wait
state while I/O is going on.  What services/tasks are being performed on
when running windows v.s. Linux?

All I know is, there isn't some hidden defect in "Linux" causing every
system running it to use more electricity and over heating systems.  Then
again, maybe Linux is conspiracy cooked up by the oil companies to increase
demand for their products.  :-)
