Roofus

Roofus is a radio-controlled snow plow designed to remove snow from roofs of buildings (thus, the name Roof-us) where it would be particularly risky for a human to do so.  Personally, I would like to employ it for my driveway during the winter and sit back with a warm coffee, directing it’s efforts.

Smart Rifle That Fires Radio-Controlled Bullets

Smart Rifle:  Fires Radio-Controlled Bullets

The XM25 rifle is being developed for the US army.  

A rifle is being developed that will fire radio-controlled ‘smart’ bullets that will target enemies no matter where they hide.

The XM25 rifle uses bullets that explode when they have travelled the set distance showering the people below. Soldiers will be able to use them to target snipers hidden in trenches rather than calling in air strikes.

Cheaper And More Reliable Lithium-Ion Batteries

Cheaper And More Reliable Lithium-Ion Batteries

Lithium-ion cells that use polymer electrolytes can be affordably packaged in compact, flexible pouches  

A new incarnation of lithium-ion batteries based on solid polymers is in the works. Berkeley, CA-based startup Seeo, Inc. says its lithium-ion cells will be safer, longer-lasting, lighter, and cheaper than current batteries. Seeo’s batteries use thin films of polymer as the electrolyte and high-energy-density, light-weight electrodes. Lawrence Berkeley National Laboratory is now making and testing cells designed by the University of California, Berkeley spinoff.
