I have been watching the Masters golf tournament on the Web. My limited AT&T 2.5Mb/sec connection gives me an HD-quality view almost as good as cable/broadcast TV.
I see no reason why my Tiger Woods PGA Tour PC game could not let me play along with Tiger's group in the Masters in real time.
This would be very cool!

They can last about 2,500 complete cycles or 4,800 80% discharge cycles. (From the wikipedia article linked elsewhere). Presuming a power outage once a week requiring 80% discharge, it would last about 90 years, if the number of cycles is the only thing determining its longevity.
That is 10-15 years when used as a night-time backup for solar collection.
This might be useful.

so it holds 32MW
No - it can hold 32MWh (=115.2GJ). Batteries hold energy not power. Since power is energy per unit time you have to multiply it by a time to get energy.
Thank you, 007, for clearing up this little misunderstanding.
I wonder how long this battery will last and what the cost of a refurbishment is. Also, how does the lifetime change with more dischare/charge cycles? I think these numbers are as important as the initial cost, but usually do not get mentioned.
A $25M batter which lasts 50 years sounds like a pretty nice piece of technology if it can be discharged/charged daily. If it lasts 5 years and has a 100% refurbishment cost, it does not sound so great.

People like the higher-ups at Microsoft (or most companies, I believe) do not care or want to hear about these issues.
If it does not involve a bonus (for the executive) or making them look good (the executive), engineers have to shut up and smile.

p.s. Of course, this is my opinion--not what I would do, and it goes against good ethics. But, who in Silicon Valley cares about ethics?
Why are people marking this as a troll?
As far as I know, it is true.
I suppose my comment, "But, who in Silicon Valley cares about ethics?" is a bit of a troll, but based on reality. For example:
I was offered a job. The HR department at the company pressed me to make a decision about taking the job. As a result, I lost the opportunity to play-out the interview process for a much better position.
When I described this tough problem to a well-known Silicon Valley CEO, he said I should have taken the job (as I did), kept up the interview process with the other company (I told them I was taking another job), and then quit the job I took if the better one panned out. He specifically said he had done the same thing, which involved working at a company for 1.5 weeks and then quitting for a better offer.
Maybe it is just me, but this seems wrong. But, in Silicon Valley, it appears to be business-as-usual.
