| Energy from a hole in the ocean 
Here is my idea in very rough form! Go out to the ocean where it is approx 1 mile deep (but this might work also in a deep lake where it is only 500 feet deep) and put down a metal pipe maybe 30 ft in diameter (also consider only 5' diameter). Pump the water out of it and every 300 to 500 feet have a turbine in the pipe which generates electricity. Let water fall down through the pipe until it gets to the bottom where (and this is either the strength or weakness of my idea)...1- it has heated up so much because of friction that has turned into steam and will automatically rise in an adjoining pipe and with fans and some of the generated electricity blown up and out back into the sky or...2- if it has not heated up enough to form steam it should be close to it so that a little bit of electricity can turn it into steam and again get rid of it,3- how much electricity would it take to force the water out into the ocean at that lower depth? (probably too much), and...4- what does the increased atmospheric pressure at the bottom of the 1 mile pipe do to the whole situation? Or perhaps drill a hole further down into the ocean bottom where the heat increases and pump the water into that so it again turns into steam. I realize that this whole thing probably does not make any sense, but it might stimulate your thinking in some other area.One question would be what is the minimum distance that water has to fall to heat up 212 degrees due to friction? (as the pipe probably shouldn't be any longer than that. Good luck with it.Reward: cheaper source of non-polluting energy for all

| Fake Speed Camera
Many people would like to have a speed camera in their neighbourhood. This will contribute to a safer environment for the kids, because the cars that pass by will slow down. Why not make a speed camera look a like, that people could set up.

| Accommodation for the homeless
This system will bridge the gap between homelessness and working class. It's a system where people can work for a few hours and in return are given points they can exchange for accommodation. There are 300,000 homeless people of working age in England even more in the US. My inspiration has come from homeless people that work in third world countries. Local businesses that contribute will outsource work to the homeless on a minimum rate per hour bases. The work could be carried out at a local center not far from the accommodation and the homeless population. The type of work could vary from sorting, packing, stripping, cleaning, making furniture etc. 3-4 hours worth of work equals one room for the night. The quality of work will be monitored and the more hours completed the more points they get added onto their account.Homeless people want a place where they can stay safe, warm with privacy and freedom. This block of apartments will give them that. The place will have a check in, security and cleaning system similar to hotels. The room sizes will be similar to student accommodation as well as shared kitchen and bathroom facilities. To keep the cost low the rooms will be somewhat plain. The place will separate females from males and couples.This system could even be a business that makes a little profit. Local businesses that get involved will benefit by recognition and low cost labor, and the homeless get good night sleep feel better overall.Reward: Fame and fortune
