Electric motorcycle smashes records

The KillaCycle, an all-electric motorcycle, is now the fastest electric vehicle of all time.

At a drag race in Chandler, Ariz., the bike completed a quarter mile in 8.168 seconds, breaking the six-year-old record of 8.801 held by Dennis Berube with an electric car for more than six years. The bike cranked it up to 155.87 miles an hour. Even more impressive, it hit this level of performance twice, on April 3 and April 4.

The bike is powered by 990 lithium ion cells from A123 Systems, a Massachusetts start-up that is also making batteries for General Motors. (A123 also makes the batteries for the Atlas Powered Rope Ascender, a device invented at MIT that can scoot a person 300 feet up a rope in about a half a minute.)

An earlier version of the bike only had 880 battery cells.

Panasonic to begin mass-production of long-life Li-ion battery system for solar-powered homes in Europe

Panasonic to begin mass-production of long-life Li-ion battery system for solar-powered homes in Europe : Panasonic Corporation will begin mass- production this month of a compact, secure and long-life lithium-ion battery system the company has developed for European homes. This marks the first time for the company to produce in volume such a system designed for Europe. The lithium-ion battery system consists of the Panasonic battery module with nominal capacity of 1.35 kWh and a battery management system designed to control charge and discharge of the battery in accordance with customer needs. The battery system stores excess energy generated from the photovoltaic (PV) power system during peak hours of PV generation and discharges the energy as needed, providing a solution as a household battery storage system that helps self-consumption of solar-generated power. It will also enable households to reduce the dependence on grid power and facilitate the further spread of green ener...

Short notes on Open Access, Peer review & (insane) publications

Image
This is insane! As a long term peer reviewer I read all articles (not only under review) very carefully. From relatively wide observation the only half of the submitted papers might be accepted for further publication. Not counting in this half the articles which need some (more or less) modifications. Indeed, there are almost half of the articles which went through my hands have a very low quality. These include repeating/copying someone else's research, very poor understanding of the obtained results, not willingness, even to try to explain the obtained results, but just referring to previously published articles (from other researchers)  (which means their result is not unique). Since I do not connect with the publishers other than by e-mail as a reviewer or author, I do not know how busy are Journals is to feel the issues. However, I understand that the publishers have to earn some money from what they are doing. Good it or not (very much) for the progress is a big question...
