remember the good old days when watch’s had a mainspring?
why can’t we use solar or wind to wind a mainspring during the day, and use the mainspring to power generators at nigt.

[...] Electric vehicles and grid storage represent huge potential markets for new energy-storage technologies. As startups Tesla Motors and Fisker Automotive work to advance electric sports cars, companies such as General Motors Corp., Ford Motor Co., and Volkswagen are rushing to come out with plug-in hybrids. And as utilities work to meet state renewable-energy goals and add more solar and wind power to their portfolios, energy storage to help smooth out the intermittent power from those sources is becoming ever more critical.

[...] Nor does it list costs for its energy storage systems, either in kilowatt or kilowatt-hour terms. In general, big (100-300 megawatt) underground gas-fired CAES storage costs about $600 to $750 per kilowatt of storage capacity built, and about $100 per kilowatt-hour of energy delivered, according to the Electric Power Research Institute. Smaller scale (10-20 megawatt) above-ground CAES costs about $1,000 to $1,800 per kilowatt and $200 to $250 per kilowatt-hour, EPRI reported — still cheaper than pumped hydro to build, if not to operate, and cheaper in kilowatt-hour terms than the battery technologies EPRI surveyed in its 2008 cost comparison. (Here’s a handy primer on various energy storage technologies.) [...]

I understand the advantages that lithium ion chemistries hold in mobile power applications. Batteries come in all sorts of varieties because of the nature of the power need. Just because a chemistry works well for something doesn't mean that it works well for anything. I'm not clear why lithium ion is a stronger candidate than other battery techologies in applications where weight is not an issue (static back up power). Any informational links or comments addressing this would be much appreciated.
