Cleaning the air with roof tiles

Researchers created a roof tile coating that when applied to an average-sized residential roof breaks down the same amount of smog-causing nitrogen oxides per year as a car driven 11,000 miles.

Clean power from waste heat

Siemens has developed a technology to use waste heat, which previously had gone unused, to generate electricity. The solution employs silicone oils, which have a lower enthalpy of vaporization than water, and is needed because waste heat produced in industrial plants or power stations often does not have enough energy to drive a turbine with steam.

Climate engineering can't erase climate change

Tinkering with climate change through climate engineering isn't going to help us get around what we have to do says a new report authored by researchers at six universities. After evaluating a range of possible climate-altering approaches to dissipating greenhouse gases and reducing warming, the interdisciplinary team concluded there's no way around it. We have to reduce the amount of carbon being released into the atmosphere.

Toxic computer waste in the developing world

As the developing world continues to develop, standards of living and access to technology increases. Unfortunately, as personal computers, laptops and mobile phones become increasingly common so the problem of recycling and disposal of such devices when they become technologically obsolete rises too.

Cyborg plants as environmental biosensors (w/video)

By using the same sort of technology that measures brain and muscle movements in human beings, Dr Vitaletti and his team think we can better understand what is happening in the environment, and in plant-life as a result. He calls this blend of living tissue and digital sensors 'cyborg plants'.

Transforming hydrogen into liquid fuel using atmospheric CO2

Scientists have completed their solution for transforming hydrogen gas into a less flammable liquid fuel that can be safely stored and transported. Another possible application of their technology would be to use atmospheric CO2to synthesize a number of useful chemical products.
