Wireless Eco-Friendly chargers for Mobiles

Today, almost everyone is using cellphones, but the major problem everyone faces is that they have to plug in a charger to the wall and connect it to the cellphone for charging it's battery to continue using the cellphone...

What if....charging can be done without wires as people travel...
Imagine...you are travelling, your cellphone's battery is dying out and there's no electrical source around you although you have the charger which is useless in this case...

The solution to this problem can be that the energy from the waves travelling in the atmosphere can be exploited, and this energy can be used to charge your cellphone, anytime, almost anywhere...hence, eliminating the need of carrying a charger everywhere...

The idea is completely eco-friendly.

new way to advertise your products

A new way to capture the attention of more people is simple. Use the doors of elevators to display messages to the occupants. What does everyone do when they enter an elevator? They turn and look at the doors. With the ultra thin plasma screen televisions you can display rented space on the doors of elevators and reach a number of people.

idea to save environment

This idea sort of falls under environment
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.
