Researchers at the University of Bath have converted a network of PCs to DC power, taking them off the power grid to cut noise and save money and power. The move, the first time this has been done in the UK, also allows the network to be powered directly by micro-power systems such as wind turbines

Scalable low-volume production method for moulded polymer bipolar plates simplifies processing and cut manufacturing costs
Southampton startup Bac2 is demonstrating moulded bipolar plates for fuel cell stacks that are made using its patented ElectroPhen electrically conductive polymer. The process reduces the cost of fuel cells because they can be moulded for high volume production and is economical to tool-up and mould relatively small quantities of plates, sometimes just a few hundred.
The unique mould-flow approach means that the plates also do not need post-processing, such as surface machining or drilling, after moulding, further reducing costs and cutting waste.
The ElectroPhen bipolar plates are available for many different types of fuel cell stacks, from high-temperature and low-temperature polymer electrolyte membrane (PEM), direct methanol, alkali and phosphoric acid designs. Unlike those made from metal, the plates are chemically inert, do not corrode, will not poison fuel cell electrodes and are rugged enough to withstand the harshest environments. They are made using a simple,
2-stage, mix-and-mould manufacturing process.
In addition to moulded plates, Bac2 supplies blank plates that can be easily machined for fuel cell development work. Blank plates are available from stock.

Two of the University of Bath’s innovative buildings are to be tested for their green credentials.
The Technology Strategy Board (TSB) is funding a total of 17 developments in the first phase of a four-year, £8m programme that aims to help the construction industry as a whole to better understand the performance of different building types, design strategies, construction methods and occupancy patterns, and the relative contribution of various factors to the eventual performance of the buildings.
Dr Andy Shea, from the University’s Department of Architecture & Civil Engineering, will be undertaking an in-depth, two-year study of the buildings within his research group BRE Centre for Innovative Construction Materials. “This research will allow us to look in very fine detail at exactly how each of the buildings is performing,” he said. “Typically there is a significant difference between the calculated environmental standard of a building on paper and that achieved once a development is in use. This research will be enormously helpful in not only advising the University of any changes that could be made to the two buildings, but also in providing the industry as a whole with information that can be applied to future developments.”
The research will involve a team of people examining in detail the exact way both buildings are used, the functions performed in them and the equipment used.
“The findings of our research into energy consumption and building usage of Woodland Court will be quite unique and have the potential for impacting on student accommodation design across the country,” said Dr Shea.
Research at the University of Bath will begin in April and continue for two years
