Shades of the Future

There's interesting potential in Hindsight

Looks like Lance Armstrong might have a new pair of sunglasses for his comeback tour. The blogs lit up in the past few weeks with attention surrounding a pair of Nike sunglasses that increase a rider's peripheral vision from the standard 180 degrees to up to 240. Given Lance's pension for wearing yellow, the new specs could come in handy. Only problem is that Nike isn't actually making the glasses. Confused? We dug into the mystery.

A House That Walks

Don't like your neighbors? Just stroll away

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)

Power Struggle

Full story inside Popular Science, out now!

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.

Steaming Down the Road

Full story inside this issue of Popular Science, out now!

Ten years of toil for a ride lasting less than two minutes -- that's the trade a team of Britain's finest engineers, mechanics and speed junkies have made for a chance to break the century-old speed record for a steam-powered vehicle. Using propane to turn 10 gallons of water a minute into superheated steam, they expect their 25-foot-long Steam Car to top out at 275kph, shattering the record by more than 60kph.

Riding in the Rain: Peugeot HYmotion3 Compressor Concept

Peugeot looks toward a future of fuel-efficient, all-weather scooters replacing cars for short, urban jaunts

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.

A Plastic Bicycle

Pre-molded, lightweight parts make for a new kind of ride

Forget the carbon-fiber bike that costs more than your house. How about one made of plastic? The Innervision bike is a design concept by industrial designer Matt Clark that ditches high-cost complex materials for pre-molded plastic parts.

A More Efficient Hybrid

Reusing exhaust makes for a cleaner, more capable engine

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.”
