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.
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.
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.
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'.
For the first time, researchers have experimentally shown that the thermal conductivity of lithium cobalt oxide, an important material for electrochemical energy storage, can be reversibly electrochemically modulated over a considerable range.
New research suggests advantages of the smart analysis in energy consumptions of discontinuous production processes, all in terms of minimizing production costs. This research opens the door to improvements in the sequencing techniques and machine scale work assignment.
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.
Consumers who charge an electric vehicle on a regular basis may leave a data trail. With each charging process, the system saves when and where it took place and which customer paid for it - a privacy risk, say researchers.
It converts chemical energy directly into electrical energy. Still, there hadn?t been a market breakthrough for the fuel cell. The systems were too complex. Now, Fraunhofer and Vaillant have developed a simple device for home use.
Organic solar modules have advantages over silicon solar cells. However, one critical problem is their shorter operating life. Researchers are working on a promising solution: they are using flexible glass as a carrier substrate that better protects the components.
