Organic mega-flow batteries, inspired by rhubarbs

There are a number of grid energy storage methods, including flow batteries, which have the potential to be scaled up with increased tank sizes, but that would be expensive due to the cost of metals involved in the process. Enter a research team from Harvard's School of Engineering and Applied Sciences, who have developed an organic mega-flow battery that utilize quinones, similar to those found in rhubarbs. The quinones serve as charge-carriers in chlorophyll during photosynthesis, with minimal degradation during the process, which is ideal for batteries used in large-scale energy storage and distribution. Some day, energy may be stored in "rhubarb batteries." (Abstract on Nature, paywalled article).

Man, they said we better accentuate the positive... eliminate the negative... latch on to the affirmative....

Microsoft introduces "an amazingly obvious tweak to battery tech that should save us some headaches, as well as several trillion hours of head-scratching and peering into dark holes." The innovation, called "Instaload" is a simple, low-tech battery contact design that allows cylindrical batteries (disposable and rechargeable) to be inserted in either direction, so users don't have to worry about which end is positive or negative. How? It puts a set of positive and negative contacts at both ends of a battery compartment. (From Microsoft: Press Release / Overview / Technology Brochure (pdf)) [more inside]

Adventures in Rechargeable Batteries

I'm not sure what the exact definition of geek is, but I think "enjoys recharging batteries" has to be very high on that list.
