| 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

| Planning for preservation of our planet
Just back from a conference where I saw a demonstration of a software simulator used in a negotiation among the institutional leaders of a city, a group of farmers and companies delivering water to the city. The negociation was about water beeing polluted by pesticides used by the farmers. I found the software very useful to elaborate scenarios consequent to the behavior of the different parties and to get the consensous of the parties on a certain scenario.Such a software could be used to elaborate scenarios on the evolution of our planet and used by representatives of the major countries to run simulations on consequences of certain decisions (e.g. impact of production of certain gas on the ozone, impact of use of pesticides on water, impact of demographic growth of certain countries on famine...). The software should be run by an international independent body (e.g. the UN) and the simulations should allow the leaders of the countries to agree on possible future scenarios of development and avoid actions that could lead to the destruction of our planet.Reward: let me help in the development of the process

| Clean Air
This idea sort of falls under environment, but I bet more people would look at it here, so here she goes.Busses travel in most cities for at least 15 hours of the day. During that time the bus may cover up to 300km. A filter placed on the roof of the bus would see a fair amount of air in one of those days. For example, if the dimensions of the filter were 2.5 x .5 meters then in the course of the day one bus could filter approximately 250,000 cubic meters of air. Filters could be washed and pellets made of the dirt collected. These pellets could be disposed of properly. This would make the cities a cleaner place. The governments could subsidies the bus companies and every one would be happy.Reward: Recognition
