Popular Science celebrates the eternal human urge to go bigger! Better! Farther! Inside, a look at three vehicles with the need to exceed.

Houses are normally fairly stationary objects, and that's not considered a bad thing. But innovation never stands still, and a new prototype house that can walk on six legs has been built . The house is ten feet high, powered by solar panels, and is outfitted with a kitchen, toilet, bed, and wood stove. Last week, the house, a collaboration between MIT and the Danish design collective N55, took a journey through Cambridgeshire in England as part of an art project at the Wysing Art Center. Designed to move at the muscle speed of a human, the house walked at about five kilometers an hour around the 11-acre campus. (See video)

The battery that will power the Chevrolet Volt weighs approximately 400 pounds and, stood on end, reaches a height of six feet. The $16,000-plus, T-shaped monolith contains 300 individual three-volt lithium-ion cells, bundled together in groups of three, then wired in series and kept from overheating by an elaborate liquid cooling mechanism.

Quick, name a car with three-wheel drive. Okay, trick question; this isn't quite a car, but Peugeot's idea of a fuel-efficient all-weather runabout. The HYmotion3 Compressor Concept foresees a hybrid vehicle in more ways than one: part gasoline-, part electric-powered; part car, part scooter. The French automaker says it offers the stability of a trike with the protection of a safety cell similar to that which supports occupants of a Smart car.

One of the first things Eric Mattessich discovered in engineering school was that the typical internal combustion engine blows about 70 percent of the energy it creates straight out of the tailpipe in the form of heat. So, he wondered, could he adapt the kind of heat-recapturing mechanisms used to make powerplants more efficient to work on hybrid cars? “The technology has been around since the 1900s,” he points out. “It’s just that no one has put it into such a small package before.”
