Emily Cummins is an inventor with a focus on helping the environment. This wouldn't be so unique if it wasn't for the fact that she is only 21, and has been inventing since the age of four when her grandad gave her a hammer.
Starting by taking things apart and rebuilding them with her grandad - who she describes as an 'inspiration' - in his shed, Emily progressed and won a barrage of awards and competitions at school for inventions such as a toothpaste dispenser that minimises waste, which she came up with at just 15 years old. She went on to become Cosmopolitan's Ultimate Save-The-Planet Pioneer in 2008.
Currently in her 3rd year of university at Leeds, she studies part time so she can work on her inventions, and dedicate time to inspiring young people.
Emily's best known invention is the sustainable fridge, (pictured with her) which she also produced at school, and is set to change lives in the third world, as it is used to hold medicines. Emily is currently working on a second generation version that is intended for commercial use.
Emily believes that all new inventions should be green. She says "This concept - to maintain the quality while neutralising the damage to the environment - must be extended to all the other appliances we can't seem to function without such as TVs, cookers, dishwashers, computers, even cars."
"Just like Trevor Baylis's wind-up radio, the key is to creating quality green alternatives to the items which people have come to rely on."
