Why graphene hasn’t taken over the world…yet

Graphene is a form of carbon that could bring us bulletproof armor and space elevators, improve medicine, and make the internet run faster — some day. For the past 15 years, consumers have been hearing about this wonder material and all the ways it could change everything.

Easy-to-Build Electromagnet lifts over 50 lbs

A powerful electromagnetic made from a microwave oven transformer is demonstrated. The electromagnet lifts over 50 lbs with a AA battery. Please subscribe, like and share if you enjoy the video so I’ll know if I should make more. WARNING: Make sure you know what you are doing if you recycle parts from a microwave oven. Cut the cord off the unit before opening it to avoid shocks. Do not open the magnetron unit (the square box that produces microwave radiation) since it contains toxic materials. You only need the transformer for this activity. Do not plug the microwave in until the high voltage winding has been removed. One note about electro-magnets is that they typically cannot pull objects with much force through air. Large forces can only be generated when the magnet is in contact wit

Spark Africa – Kenyan solution for charging mobile phones – Episode 2

It is estimated that in Kenya about 17,5 million of the total 38,5 million inhabitants own a mobile phone. But in rural areas electricity is a problem. Students of the university of Nairobi came up with the solution: the ‘Smart Charger’. The charger works quite simple: one connects it to the dynamo of a bicycle. The device transforms the power into electricity that can charge the mobile phone. After about one hour the phone will be charged. News about Africa is very often filled with stereotyped images of famine, war and disease. But there is also another side to the continent. Fast-growing economies and investment opportunities. The Dutch production company Interactive Africa focuses its lens precisely on the innovative side of Africa with its online video reports Spark Africa.
