Hot air balloon set a record for altitude

Many scientists were shocked when the first time a balloon could fly into space, reaching a record high of 28.8km, more than the previous record to 6.4km.

The balloon balloon, called Tandem , was invented by JP Aerospace, California, with a total cost of about $ 30,000.

Tandem has two balloons made of carbon fiber, two electric motors attached to two propellers. Tandem is unmanned and controlled from the ground, in which two balloons and two engines alternate depending on the dilution of the air.

Tandem can fly into the stratosphere of the Earth. And in the future it could be used for missile research, or carrying something to the air research station.

"The big aerospace companies have been trying to do that for decades ," says John Powell , who spent hundreds of thousands of dollars on that. But we only cost $ 30,000, and it takes five years to develop it. '

The invention is considered by scientists to be a costly 'dough' but high efficiency.
