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.

The patent-pending technology uses a laser beam's energy to precisely transfer the ultra-thin chips.

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.

ECONOMIST: Physics

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.

This involves injecting boron atoms into the cancerous organ, and using a neutron beam to split them into destructive high-energy particles.

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.
