Israel will reportedly be using their new "Iron Beam," a laser beam that can take out enemy rockets. Unconfirmed videos are circulating showing these laser beams are now taking out enemy threats. While an interceptor missile from the Iron Dome costs ~$50,000, the laser beam interceptor costs as low as $2 (WSJ). The beam uses 100kW of power, 100 times more power than an average home uses.
