Grand Old Tree

Busy day again today, played squash on the way home and stopped off to get some dinner giving me a chance to photograph this huge old tree in the shopping car park.

Learned something new today, a technology which is extremely light, extremely thin, extremely strong and able to conduct electricity. It has the potential to change so much, it's called graphene. The patent office is being bombarded by so many new patents for products using it, almost 5000 to date!
