"The first series production cars to incorporate 48V technology in one form or another have hit the road in recent times, and further integration of 48V architecture is expected in the very near future. The Bentley Bentayga and the Audi SQ7 are the first two vehicles to incorporate a higher voltage electrical system, and the industry as a whole is gearing up for further development in the coming years."

Growing a mixed "lawn" of two kinds of nanowires can make a new kind of light-sensing array that could be made in metre-scale sheets. The researchers behind the prototype say such cheap, high-quality image sensors would allow uses not conceivable using today's more expensive technology. Current sensors, such as those found in digital cameras, are made like any other silicon chip - they are carved out from a block of material. The new nanowire sensors are instead built from the bottom up, using chemically-grown nano-sized components. A research team led by Ali Javey, at the University of California, Berkeley, developed the process. They start by growing an unruly "lawn" of nanowires on a surface. The crop is then printed onto another surface, a step that simultaneously tidies them up. "At the first stage, the nanowires are more-or-less standing up, like a bad hair day. But during the printing process, they effectively get combed," says Javey. The nanowires, which are a few tenths of a millimetre long and a few tens of nanometres wide, can be printed onto anything from silicon to plastic or paper. Whatever the surface, it must be prepared with a pattern that guides the nanowires to predetermined locations. To make the functioning sensor, two different "crops" of nanotubes are printed onto the same surface. Cadmium selenide nanowires produce electric charge when hit by light, while those made from silicon-coated germanium act as transistors to amplify that charge.

UK telecoms provider BT is to invest £1.5 billion ($3 billion) to roll out superfast broadband to up to 10 million UK homes by 2012. The system will enable services such as video conferencing, video on demand, and other high bandwidth activities. The programme is Britain's largest ever investment in superfast broadband, which will deliver speeds of up to 100 megabits per second. The fibre will be linked to a cabinet in the street and in some cases - such as the Olympic village for the 2012 Games - directly to the premises. Homes linked to a fibre-to-the-cabinet network will receive initial speeds of up to 40 Mbps, due to the copper cable that connects the house to the cabinet. However, BT expects this to increase to 60 Mbps with new technologies. Those on a fibre-to-the-premises network will see speeds of up to 100 Mbps.

Pennsylvania Gov. Edward Rendell has approved a bill that establishes a $500 million fund to support alternative energy projects. Special Session House Bill 1 authorizes the Commonwealth Financing Authority to borrow $500 million, most of which will be split into six funding sources relating to energy efficiency and renewable energy: $80 million in grants and loans for solar energy projects; $100 million in grants, loans, and rebates for up to 35 percent of the cost of solar energy projects at residences and small businesses; $165 million in grants and loans for alternative energy projects, excluding solar energy, at businesses and local government facilities; $25 million for wind and geothermal energy projects; $40 million to help start-up businesses involved in energy efficiency technologies; and $25 million in grants and loans to improve the energy efficiency of new and existing homes and small business buildings.
