Personal News Reader

Today I was talking to Hrishi and he told he is not able to give much time on reading news paper now days because he has to catch bus daily morning, so I told it's good, you can read in bus. Then he told me that it's pain reading in bus and it give strains to eyes.
So here comes the idea:
Personal News/Feed reader (for mobile):
It's will take feeds from internet and read out (speak) the headlines one by one, whenever you want to have more info on that news, it will read out the actual content. This can be done using simple text to speech engine.

Electricity at home from water at overhead tank

It's just a thought, but can be converted to a useful product.
I think a small amount of electricity can be generated from the water at overhead tank, using turbine.
Attach a small turbine in the pipe going from tank to house, such that whenever someone opens any tap in the house, the water will go thru the turbine and will rotate it, that rotation will generate some electricity which can be used to charge a battery, which can later be used at need. I think this product can be very useful in villages where elex comes and goes frequently.
The questions here are:
* how much electricity will this small turbine generate?
* will this slow down the force of water in the tap? If yes, will that be a problem?

collaborative movie library

Last wednesday at Rakhi I went to my cousin sister for the Raksha-Bandhan. There I saw that Jijaji had a huge collectiion of movies (cds/dvds). So an idea (re)emerged on my mind. Why can't we have a collaborative movie library. I'll work same as netflix/70mm, but we won't have any storage. All the movies will with users, and we will give them platform to share their collection with other's and make use of other's collection.
I have many dvd's of many movies, but they are allmost of no use to me as I have seen them. I want to see other movies, which today I need to buy or download. Here in this library I'll share my collection and whenever somebody will borrow my dvd, I'll get some points. Then I can borrow any movie from those points.
The collaborative library will provide 2 things.

1. The platform to share the collection with library and search browse the full library. Choice of vast viriety of movies.
2. The logistics (that's the part I don't have idea with): the pickup and drop at door. So that you wont have to go anywhere. For this part I'll need to see how 70mm do it. They have local guys going to doorstep of each customer to give/take movies.

Revenue model: subscription basis. 70mm has plan like Rs 50 permonth. Our's should be like 10-15 Rs per month. If the model is in Bangalore, and library has around 10K active users, the revenue is 1lac. per month, the main expenditure will be pickup boys and server bandwidth.
The idea can be generalized to books too. I find no difficulty in that once the basic platform is in place.
