MIT researchers rethink electric-car batteries

Researchers at the Massachusetts Institute of Technology say a new battery design for electric vehicles could be a lightweight and inexpensive alternative. The goal for the team's three-year project, launched in September 2010, is to have a functioning prototype ready to be engineered as a replacement for existing electric-car batteries. At this point in the project, the prototype uses a “semi-solid flow” to separate the two functions of a battery--storing energy and discharging it when needed--into separate physical structures.

Rinspeed microMAX

Rinspeed has revealed its microMAX concept car as its latest Geneva-bound offering, which it hopes will revolutionize urban congestion. The microMAX, designed by Rinspeed boss Frank Rinderknecht, explores the idea of car sharing and is designed to be small enough so that it can easily navigate city environments but uses upright seats to maximize space. The five-seater concept is apparently no bigger than a Mini Cooper and has space for a stroller or shopping cart as well as a coffee maker and refrigerator.

Chill out: coolest truck ever made of ice

Just as humans find it difficult getting out of bed on a cold morning, cars often don’t like starting when temperatures are below freezing. Not only is there more pressure on car batteries in the winter as we rely on them for heating and lighting, but they also struggle to hold their charge. So, in a bid to prove that their batteries are unbeatable in the cold, a Canadian company has built a pick-up truck out of ice.
