An anonymous reader writes "Residents of a southern Israeli town want a real-life laser cannon to protect them against Palestinian rocket attacks. And they're suing the national government, for failing to provide the ray gun defense. The U.S.-Israeli Tactical High Energy Laser project was widely considered to be the most successful energy weapon ever built. But the toxic chemicals needed to generate THEL's megawatts of power made the thing a logistical nightmare. It was scrapped. Now, the residents of Sderot want it back. And they're taking Prime Minister Ehud Olmert to court to make it happen."
