Abebe Negash is a refugee from Ethiopia, who is studying at University of New Hampshire. He has invented a machine which may help in reducing the amount of pollutants from a car’s exhaust pipe. Preliminary tests with the not-so-elegant device (it is made out of PVC pipes and hoses, strapped to a trailer hitch and filled with brown solution) have gone well. Now he needs to test it more. However, he is a bit worried that someone may think of him as a security threat – with his ethnic skin and the bulky machine he is using. And he has reasons – people have insulted him in the past, including calling him a terrorist. However, he does not hold any spite. Negash says, “I can be more useful than the people who do that!”
Still, he is trying to test it in other ways, even if some of those methods may not be scientific. So far, according to those methods, he has been able to reduce carbon dioxide emissions by around 10%.
Negash uses plant-derived liquids, since according to him, plants consume carbon. Details of the invention were not available for evaluation at the time of writing this.

Let us hope Negash is able to successfully test his invention – even 10% reduction in CO2 emissions is very good news, if he can achieve it.

News from New Zealand:

Sometimes, an invention need not involve bleeding edge technology to make a difference in people’s lives.

One such invention enables Ian Sadler, a man with cerebral palsy, to indulge in his passion for painting. His tutor, Karl Wulff, made a helmet for him, which could hold his paintbrush.

For creating the helmet, Karl used fiberglass, after making a plaster cast mould of Ian’s head. AW Trinder, an engineering firm, created a special apparatus which helps in holding the brush steady.
According to Karl Wulff, the invention helps strengthening Ian’s neck muscles, and should help in improving his ability to move.
