Solar powered remote controlled aircraft

On December 17, 1903, when Wright brothers build the first aircraft, it became discovery, that changed the world completely. They build fixed-wing aircraft which are capable of flight using wings that generate lift due to the vehicle's forward airspeed and the shape of the wings. In the last century though, everything improved from the design of aircraft, fuel efficiency and power of the engine but aircraft fuel which is most important has not changed and become the leading cause of global warming.

Why?
If you read airplane history, you would find that human need and desire of flying is more powerful than flying with renewable energy. So, focus in the last century was only on designing and improving the efficiency of the engine and not on changing its fuel.

So, why now?
In the last decade, awareness of the general public about climate change has increased significantly. This awareness and fuel price that is rising at rocket speed creates catastrophic effect, which pressurizes us to think about alternative fuel for aircraft and one of these alternates is Solar Energy, which we are going to discuss today.

Is it possible?

Yes it is, recently Swiss-made Solar-Powered Plane, Solar Impulse completed its 4000 miles journey between Europe and Africa successfully. You can read more about it at the news website msnbc.

Fabrication of Cam less engine

In this modern world where companies are focusing on green energy, cam less engine can become a great alternative.

A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion or vice-versa. In an engine, it is connected to a shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path.

In a traditional engine, the camshaft has a very important role to play while opening and closing of a valve. It was a necessary evil for an engine functioning. Furthermore, because of the camshaft, engineers need to choose either an efficient engine or a powerful engine but not with both qualities. This is one of the most important factors that make a camless engine a necessity. Though the idea of cam less engine existed from 1899, it has become the need of the modern world now, when we need power and efficiency both.

Water fuel Power Generation System

 Is it possible to use water to power our cars?

Some people claim that it is possible and done before and other thinks, it has never been done and would need more time before this actually happens. But all of them believe that someday we can run our cars on water. I found this project idea interesting enough to discuss with you. If you are a believer in water fuel cell invented by American Stanley Allen Meyer. Then you should try this project and see whether we can run our cars on water or if we can generate power using water fuel cells? 

Pure water with the help of SMS

Pure water with the help of SMS is a project based on getting pure water using Hand Pump. Though we have already discussed various projects based on water purification such as Pedal Powered Water Filter  and  Solar-powered water purification system but in Africa, the most common source of pure water is Hand Pump. If it stops working, people get forced to drink dirty water as an alternative. This project idea solves this problem.

People living in rural areas of Africa can use a mobile phone to drink clean water. Researchers of Britain has to build Data Transmitter which can be embedded inside the hand pump.

This transmitter sends SMS when the hand pump stops working. This transmitter would be installed in 70 villages of Kenya.  Information about this technology has been discussed at the General of Hydroinformatics.
