Researchers found that power could be sent to a free-flying drone via a beam of microwave radiation. The team estimated the efficiency of this process and compared it with that for a fixed-position ...

The microwave plasma propulsion can have three times the efficiency of chemical rockets while having as much power as chemical rockets. Other hyper-efficient propulsion is far more limited in how much ...

Microwave plasma dynamics encompasses the study of ionised gases generated by high frequency electromagnetic fields and their complex interactions with the surrounding medium. At the heart of this ...

In a study published this month in the Journal of Spacecraft and Rockets, researchers led by the University of Tsukuba have demonstrated wireless power transmission via microwaves for a free-flying ...

May 6 (UPI) --Engineers in China have developed a fossil fuel-free jet propulsion prototype design that uses microwave air plasmas. If scientists can figure out a way to turn their design into a ...

Even with SpaceX launching commercial missions to the International Space Station, spaceflight is still a costly and resource-intensive endeavor, with bigger and heavier rockets forced to dedicate ...

SAN JOSE, Calif. — A small Colorado company has successfully tested a new type of propulsion technology that it believes could eventually enable low-cost, single-stage-to-orbit launch vehicles.

Assuming we hand-wave all of the scaling questions (!!), what this really looks like is a step towards real electrically-power airplanes. If I read this correctly, this system is considerably more ...

Tsukuba, Japan – Sending a rocket into space typically requires about 90% of the rocket’s initial weight to be fuel. This limitation could be overcome by wirelessly transmitting the needed power to ...
