How many slices of bread can you toast form a bolt of lightening?

100,000 slices of bread!

It’s an awful lot of toast, but then a typical lightning bolt isn’t short on energy. It typically contains about 5 billion joules of energy.

This means that one typical strike could power a 1000 Watt, two slice toaster for 84,000 minutes in which time you could make around 100,000 slices of toast, if you are fast.
