Our current energy challenges relate to transportable energy storage. Transportable system can range in size from mobile phone batteries to systems that fit in 60 foot containers. They just have to be movable.

Why concentrate on transportable energy storage?
•   Real world situations, not academic experiments

Why a set of multiple related Challenges?
•   Full range of different technologies
•   Each challenge separate from the previous challenge
•   Shorten the current 8-15 year process of bringing research ideas into commercial product     into a 3-5 year competition based model
