In July 2013, scientists at the University of West England (UWE) developed a way of using urine as a power source to generate electricity and created the world’s first MFC (microbial fuel cell) powered mobile phone. Professor Ioannis Ieropoulos said at the time:
‘By harnessing this power as urine passes through a cascade of MFCs, we have managed to charge a Samsung mobile phone.’..So far the microbial fuel power stack that we have developed generates enough power to enable SMS messaging, web browsing and to make a brief phone call.’
However, he said that making a long call on a mobile phone is far more power-hungry. This professor believes that they will get to a place where they can charge a battery for longer periods of time.
A Google A Day may provide opportunities for fun in the classroom file students are improving their search skills.
You get three questions, and have to solve it as quickly as possible. The Google page opens so that you can search for the right answers. As soon as you have typed in the correct answer, you may attempt to answer the following question. The clock is ticking, so you loose points when you snooze.
I believe this can be an effective way to train students in improving their searching skills.
