Armour: In 1965, General Electric knocked up a prototype exoskeleton called Hardiman 1 that suffered “violent and uncontrollable motion”, according to their report. Given that it weighed the same as a car, they wisely scrapped it before attaching it to anything as squishy as a human.

A more refined version has now been developed by the (gulp!) Cyberdyne corporation: the worryingly-named HAL-5 units will be rentable from October for a cost of $1,000 per month, offering you much increased strength and, um, Bluetooth compatibility. Y'know, so you can soundtrack your rampages.

Flying: A company called Tecnologia Aeroespacial Mexicana would have us believe it produces “a complete turn-key package of a flying rocket belt, custom-made to the pilot's weight and body size.” Their rocket belt ain't too subtle - it looks like nuclear-powered turtle shell when strapped up - but they do offer full training and “24/7 expert support."
