Marx generator can it be used to power something?

[bmxrider2012]

ok so i seen some videos on youtube where people show off their marx generator and make giant sparks with them but what i want to know is can you actually use it to power something
is there any practical application for a marx generator or is it just for fun like a tesla coil ?
