NASA, America's space agency, has started using them to beam energy to remotely controlled drones.
It invented a sophisticated device that emits sound waves in a lethally focused beam of energy but never proved that ultrasound provides long-term relief or is more effective than existing procedures.
The patent-pending technology uses a laser beam's energy to precisely transfer the ultra-thin chips.
The main appeal of using an energy beam to shoot things is that it travels at the speed of light, which means, in practice, that it will hit whatever it is aimed at.
Directed energy (DE) is an umbrella term covering technologies that produce a beam of concentrated electromagnetic energy or atomic or subatomic particles as a direct means to damage or destroy adversary equipment, facilities, and personnel.
Pulsars are a special type of neutron star that rotates rapidly, emitting a beam of high-energy that spins much like the bulb in a lighthouse.

But the safety of beaming it back--proposals call for converting the radiated energy into a narrow microwave beam, which would then be collected and converted into electrical energy on earth--makes many people uncomfortable.
In an atmosphere of deuterium gas, the field generated positively charged deuteron ions and accelerated them to high energy in a beam.

But the slow decay in radiation intensity from a tabletop pulsar would make possible extremely long-range transmitters, giving far-off space probes an energy-efficient way to beam information back to earth.
This involves injecting boron atoms into the cancerous organ, and using a neutron beam to split them into destructive high-energy particles.
The technology vaporizes (but doesn't burn) garbage with arcs of electrical energy that heat matter inside their beam to 25, 000 degrees.
Increases in defense spending will seriously diffuse, if not neutralize, the energy and effectiveness of the "laser beam" Mr. Clinton has promised to bring to bear on reinvigorating the national economy.
She is working on focusing the transmitted beam into a much smaller area, so that less energy is lost along its way.
One idea is that the energy from some bursts may be concentrated into a narrow beam though no one yet knows how.
According to the automaker, laser lighting can produce a forward beam with an intensity a thousand times greater than conventional LEDs, but with half the energy consumption.
When this beam struck a target of erbium deuteride, the team detected neutrons coming from the target with precisely the energy expected if they were generated by the nuclear fusion of two deuterium nuclei.
