It may sound like a futuristic technology, but the first hydrogen fuel cell prototype was built in a cardboard box.

It was made from a cardboard crate and assembled on a trailer with a propulsive motor and hydraulic arm.

The first hydrogen tank was constructed by a group of aerospace engineers at the University of California at Berkeley in 2002.

It was a prototype for a fuel cell powered by carbon dioxide gas and oxygen that could be refueled by a propulsion system that was designed to help make it more economical to use the gas.

A year later, in 2008, another group of engineers, led by John Pert, showed that the technology could be built on a single propane cylinder and assembled in less than an hour.

In 2011, a group led by David Dao of NASA’s Ames Research Center showed that a hydrogen tank can be made from cardboard, using just a pair of screws.

In 2015, another team at Stanford University, led the project, constructed a hydrogen fuel tank that could produce enough hydrogen to run a typical home or office.

The latest iteration, unveiled in late 2016, is about half the size of a normal cardboard box, and can be assembled in a matter of minutes.

The hydrogen fuel cells are being used to power a wide variety of vehicles and power plants, from electric cars to refrigerated hydrogen tankers.

They’re also being used in the production of renewable energy, and are a potential solution to the problem of climate change.

It’s the latest example of how a new generation of people and new technology is starting to take over manufacturing, which has traditionally been a place where the older, older tech companies have kept a lot of the old tech.

But in recent years, the pace of innovation has slowed down, and companies like Toyota and Honda have begun making the big bets that the world will need them.

The company that makes the Toyota Prius, for instance, has said it will move to a hydrogen powered vehicle in the 2020s.
