Education for Every Child Printer Friendly Version
People can create a scheme where they can invest money that will be used to educate children till they are 25 years of age. After 25, these (children) should be made compulsory to return money to the scheme in installments with interest. This money will be given back to people in their old age till they die. In this way, we can educate each and every poor child in this world and let not old go hungry any more.

Debt card with age verification Printer Friendly Version
Why not take your debt card; put your picture on it; and when you swipe it to pay for booze it will verify your age.
I can't think of anyone that would give their debt card and pin to anyone, plus it has your photo on it.

Efficient wind turbines in cities Printer Friendly Version
Create a huge cone shaped Helium balloon with a big funnel like opening in the center. Now place a wind turbine in its center to generate electricity, tie this structure to ground and release it up at a very high altitude to get high-speed winds. Ropes should be tied in such a way that the concave side of the balloon faces the direction of coming wind.
The Concave shape will trap more wind and will result in greater efficiency of turbine. At high altitude there is more wind (look at kites). No need of high (expensive) towers and can be easily placed in cities.
