Follow-up report: President Obama signs Pedestrian Safety Enhancement Act into law

It looks like automakers will be required by law to add audible alerts to silent-running electric vehicles to keep sight-impaired pedestrians safe.

President Barack Obama this week signed into law the Pedestrian Safety Enhancement Act (S. 841), which will protect the blind and other pedestrians from injury as a result of silent-vehicle technology, said the National Federation of the Blind.

This plug-in Prius gives back good energy

A common argument against electric vehicles is that they'll increase demand for carbon-producing electricity and cause brownouts during peak times. But what if plug-ins could actually prevent these outages by sending electricity from their batteries back to the grid?

It's an interesting concept dreamed up by engineers at the University of Technology Sydney. Combining their research on plug-in hybrids and electrical grids, they've developed "Switch," a plug-in Toyota Prius that acts as a sort of an energy reservoir that can give back to the grid whenever needed.

The Switch uses a 4.1 kWh lithium ion battery stored in the trunk to store extra electricity that is theoretically purchased during cheaper off-peak times. The extra battery also helps power the Prius' existing NiMH battery pack and raises fuel economy to 118 mpg. … Read more
