Default Re: Universal Renewable Energy: Suitable Substitute for Morning Sex?

A potential nice new battery type. Still in R & D phase. Eliminates the need for membranes, typically a weak point by virtue of cost or susceptibility to corrosion, by maintaining a laminar flow of liquids. So far a device has been made that works. If it can be scaled up, potentially will offer storage at $100/kw capacity (guessing installed), which isn't bad.

New Rechargeable Flow Battery Could Enable Cheaper, More Efficient Energy Storage

The palm-sized prototype generates three times as much power per square centimeter as other membraneless systems -- a power density that is an order of magnitude higher than that of many lithium-ion batteries and other commercial and experimental energy-storage systems.

"This technology has as much promise as anything else being explored for storage, if not more," says Cullen Buie, an assistant professor of mechanical engineering at MIT. "Contrary to previous opinions that membraneless systems are purely academic, this system could potentially have a large practical impact."
Buie, along with Martin Bazant, a professor of chemical engineering, and William Braff, a graduate student in mechanical engineering, have published their results this week in Nature Communications.
"Here, we have a system where performance is just as good as previous systems, and now we don't have to worry about issues of the membrane," Bazant says. "This is something that can be a quantum leap in energy-storage technology."
