Clean Energy Transition

Metrolight, which has just received $9 million in a third round of funding from Gemini Israel Funds and Richard Branson's Virgin Fuels, has been riding a surge of demand for its high-frequency electronic ballast, a device for controlling high-intensity discharge (HID) lights--those bright lights used for illuminating department stores, large interior spaces and freeways. The system effectively provides the same amount of light as more traditional magnetic or electromagnetic systems, but requires less overall power, the company says. Additionally, the HID lights can be dimmed when no one is present or, if the light fixture is connected to the Internet, dimmed by a utility to prevent a brown-out. Some customers have seen their electric lighting and maintenance bills drop by around 50 percent, according to Metrolight.

The device is a piece of paper infused with carbon nanotubes and a salt, which serves as an electrolyte. Because it stores energy and conducts it, the device can act like a battery. A number of corporate labs and universities have come up with flexible batteries in the past. Power Paper from Israel makes a flexible battery printed on polymers that relies on zinc as an electrolyte. It sells it to the cosmetics industry. Japan Inc. also has trotted out a lot of prototypes. Still, these things haven't gone commercial so any advance is welcome.

Last week's news that widening a stretch of the M6 motorway will cost £3bn, or £1,000 an inch, was depressing not just because of the huge sum but for what it says about the government's spending priorities.

The lithium ion car battery created by Tesla Motors has passed a battery of certification tests that effectively remove another hurdle in the path toward selling products. Because they can burst into flames, lithium ion batteries are classified as dangerous goods, according to Erik Toomre, Director of Manufacturing Programs. "Before we ship it to the public, we have to demonstrate that it is safe," he said.
