# How Long Would the Large Hadron Collider Take to Defrost a Pizza?

*Scientific American* figures it out:

According to an old

Cosmic Variancepost, the power of one of the LHC's proton beams at full energy is 10 trillion watts (TW). (A watt is a joule of energy per second.) A household microwave produces 500 to 1000 watts of power. Let's call it 700 watts. And defrosting a frozen pizza takes about six minutes*. So that's 700 joules/sec x 360 sec = 252,000 joules of energy needed to defrost a pizzaTherefore: 252,000 joules / 10^13 joules per second =

3x10^-8 second for the LHC to defrost a pizzaThat's

30 nanoseconds(billionths of a second).

I've always hated thawing my frozen pizzas.
