Another piece on the same programme had James looking at mirror farms in Spain which reflect light to a focal point to heat water for electricity generation. I think the one he was looking at was featured in the film "Sahara"; but that one was only 400 degrees iirc.

I live with my girlfriend and our son and whenever he isn't there i.e. he's at school/visiting friends/grandparents I'm myself: happy, care free driven; as soon as he arrives home my character switches completely and I become impatient, moody lose motivation and become slightly depressed, I dislike being a parent intensely. 5 years in it hasn't got much better.
I don't think there's need for the abuse people give down the phone; but it's extremely frustrating to be put through to a call centre that deals with important personal details that don't understand half of what you're saying and vice versa.
