Contrary to media speculation Sky Mirror does not pose any danger to the
public or pigeons in the form of a barbecue ray.

Countered with some real facts by the astronomer quoted in the article
below:

http://www.theguardian.com/uk/2001/mar/07/paulkelso1

" . . . during the risk period, the sun's rays would be concentrated
into a funnel shape projected upwards towards the theatre bar. Several
inches wide and stretching for six metres, the beam would be as hot as
40 single-bar electric fires."

Notice that he is writing in the future tense, in an article
written 12 years ago. The accurate and informed report from the
Playhouse themselves makes clear that no problems have in fact
been experienced.
