This battery power device does not play MP3 tunes, but it does have an audible alarm output. The alarm sounds when a film of water bridges the contacts of the unit’s integrated electronic sensor. However, condensation or high humidity will not cause the sensor to trigger the alarm. Operating from a 9V battery that lasts about one year, the unit also provides an audible low battery “chirp” to warn of a low-battery condition. Typical applications include basement sump pumps, drain areas and sprinkler systems in residential homes, as well as commercial buildings.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
