The Goal Zero products range in size -- from units that can charge cell phones, to larger kits that can keep a refrigerator running -- but the impact is always powerful. For people that are without electricity, being able to count on a sustainable light supply can make a world of difference. Obviously solar charging kits are not going to replace the grid, but I hope they turn out to be a gateway drug of sorts, demonstrating the alternative of distributed generation (e.g. roofotp solar) to a dirty and cumbersome centralized grid that maximizes profit for shareholders and executives, and leaves customers in the cold.
