Polish company called SpaceForest from Gdynia is working on rocket powered by hybrid enginges, similar to that ones which were used in spacecraft SpaceShip Two. The goal of rockets, built in the framework of the European project named DEWI (Dependable Embedded Wireless Infrastructure) will be to test the possibility of replacing wiring communication by wireless technology.
If the experiment is going to be successful, the large rockets built in the future, can significantly reduce its weight. What is more, the same technology can be applied also in aircraft and helicopters.
Dunno, but seems like Musk has it
Well done Poland! If you have sources and time to develop satellites, means you are doing really well
