Water-propelled jetpack patented

I’m sure I’m not the only one in the room who’s always wanted a jetpack. But they’re dangerous things; not only due to the risk of flying out of control and doing yourself a serious injury, but to the potential of the engine exploding while strapped to your back. A new patent for a water-propelled jetpack removes the latter risk, leaving you at the mercy of nothing but your own piloting skills … which, considering it will only be usable over bodies of water, might not be as much of a problem as it could be. And while we’re on the subject of propulsion and fuel, a Scottish university is studying the possibility of using brewery by-products to make biofuels for car engines. I’ll drink to that.
