I went over there with the kids this lunchtime - pretty amazing heat focused into the street. Lots of journalists and TV news crews around, including one frying an egg. My youngest son found the heat too much, and ran down the street screaming "I'm burning, I'm burning!", so naturally the press then converged on us...
The funny thing is that the focal point is literally just round the corner from the Monument which indicates where the great fire of London started. What they really need now is a roof of photovoltaic panels along the pavement, and they can really cash in on it.
Here's what it looked like today: https://twitter.com/MarkJHandley/status/375265729060163584/p...
