Cheap Photovoltaics Wins MIT Clean Energy Prize

While our screens are brittle, theirs is flexible - at what they say is one tenth the price.

Another came up with a new technique to reengineer concrete at the molecular scale a process they say makes it stronger and uses significantly less energy. The students say their technology could save the equivalent output of 100 nuclear power plants p.a.

Waste Combustor Turns Plastic into Clean Energy

Imagine if nearly all used plastic was diverted from the recycling plant or landfill and used to create clean, renewable energy.

That's exactly the vision that prompted Yiannis Levendis and his team students to create a new double-tank waste combustor. The combustor prototype converts plastic waste into energy without creating harmful emissions.
