ABSTRACT Generally the cutting and plate are made in plastics. The plastics are harmful and it has many disadvantages to us. By naturally we get leaves, Leaves by using this we can make cups. It is very cheap and it does not have any chemical effects. The Leaf cup is made by a solar tea leaf cutting machine. The machine is operated by the solar... Continue Reading

ABSTRACT Researchers suggest that the amount of sunlight that strikes the Earth's surface in an hour and a half is enough to handle the entire world's energy consumption for a full year. Solar power system is one of the best renewable energy technologies which is not only cost effective but environment friendly as well.This study aimed at... Continue Reading

ABSTRACT Cell phones need electric sources to charge their batteries in order to work, but there are people in developing and third world countries that find it hard to access electric sources.In an attempt to provide an alternative means of charging to those unfortunate areas in third world and developing countries, a solar powered cell phone...

Abstract More than 2.2 million Ghanaian families in rural areas depend on firewood and charcoal as fuel for cooking [1]. This high dependency is taking a toll on forest resources due to rampant deforestation. “Ghana's forest cover, which stood at 8.2 million hectares in 1900, has now been reduced to about 1.2 million hectares, with an estimated...
