vehicle show in the birthplace of the LED. Retrofit and sleek new Tesla and (see the extras) BMW delights. http://www.electraa.org.uk/.  I was impressed that the lady from Nissan was able simultaneously to explain the V2G re-use strategy they have to keep retired lithium batteries away from landfill, and give her four-year old an icecream, from the back of her (electric) van.
