Electric cars can become electricity banks

Ever try to store electricity? It won't stay in a bottle, and you can't keep it in your sock drawer. So when you have a lot of it--say, when it's windy and your wind turbines are really spinning, or when it's sunny and your gallium arsenide photovoltaics are lighting up, or at night when the utility's generators can run unhindered--you have to store it somewhere.

New 2015 Mazda2 arrives

This is the new 2015 Mazda2 (Demio) The new Mazda2 was all but revealed at the Geneva Motor Show in March in the guise of the Mazda Hazumi Concept, but now the real new Mazda2 has arrived, or at least it has in Japan. But Mazda are captioning the photos – which are clearly of the Demio – as the Mazda2, so we can be pretty sure not much is going to change when the Demio gets the Mazda2 badge in the UK and Europe. That means the same Kodo design language Mazda has introduced across its range recently with a shield grill flowing in to the headlights, big wheel arches and horizontal lights at the back – all very much like the Hazumi.
