Less waste with water bridge

Researchers at the Wetsus research centre in The Netherlands and TU Graz, Germany, have joined forces to build a floating water bridge between two vessels that can carry electrical charge. The water bridge phenomenon was known to 19th Century scientists, but the new study uses a high voltage to show that the flowing water is protonically, rather than electronically charged, and holds the charge for a short period of time. The charged liquid bridge might be used as a novel kind of reaction vessel that will facilitate low-waste reactions.
