Tesla Powerwall Battery Economics: Almost There - "Elon Musk announced Tesla's home / business battery today. [video] tl;dr: It'll get enthusiastic early adopters to buy. The economics are almost there to make it cost effective for a wide market... That said, for large scale grid deployment (outside of the home), it still looks like flow batteries and advanced compressed air are likely to be far cheaper in the long run." [more inside]
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]
Healthy competition can advance technology, and motorsports is a good example of this. The Isle of Man TT has been a motorcycle proving ground since 1907, with a bike earning its mettle by doing ton-up on the 38 mile course. Enter Michael Czysz and his MotoCzysz E1pc. After disastrous failure at the Isle of Man TT the previous year, his company redesigned their electric sport bike from the ground up. The results could have wider implications for electric vehicles as a whole. Previously. [more inside]
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.
Toshiba develops rechargeable battery that can charge in one minute. The battery can achieve 80 percent nominal charge 60 times faster than conventional Lithium Ion batteries, and only loses 1 percent of its life cycle every 1,000 charges. In comparison to any other type of battery in existence, that is amazing.
