We're not quite sure how the pitch session went with this one, but it looks like the US Army was so impressed by toymaker Lund and Company's Hydrogen Fuel Rocket that it decided to recruit the company to build a decidedly more lethal version of it. The new system, dubbed the Variable Velocity Weapon System, will apparently be able to be switched between lethal and non-lethal modes, and be loaded with rubber bullets, actual bullets, or other projectiles, which are fired by mixing a liquid or gaseous fuel with air in a combustion chamber. What's more, the company says that the technology could be applied to any size weapon from a "handgun to a Howitzer," and it says a demonstration version could be ready in as little as six months, with full production possible within 18 months, pending approval.
