This awesome DIY railgun fires rounds with 27,000 joules of force

You NEED this for home defense. If your neighbor bought a tank....

27,000 joules equates to 19,914 foot pounds energy. To put that into perspective, a .50 BMG (the round used in the vehicle-mounted M2 heavy machine gun and the massive Barrett M82 sniper rifle) generates a maximum of "only" 15,000 fpe. But possibly the most powerful (and totally impractical) rifle round is the .905, with up to 38,700 fpe...or about as much as a 20mm Vulcan cannon round.

This could be the biggest sign yet that the battery revolution is here
