Researchers developed an artificial gill for ocean gliders, using hydrogen fuel to improve sustainability and extend mission ...

Previous attempts looked like this, a glider or an old seaplane retrofitted with an electric engine ... The bigger the battery, the more power for the plane, but a bigger battery also means ...

The idea is that a glider is carried by rocket above the Earth's atmosphere, and then it descends without power. With the ...
