The Fregolent mirror has been installed and started started operation.

The first sunny day was the 23.2.2014. We used it to check mirror calibration and a number of system checks. Unimpressed by our ongoing studies, the mirror started collecting heat energy:

The Hotel Al Cavaliere at Pordenone is the first hotel in the world heated by a Linear Mirror II. But that is not the only innovation here: as heat carrier we used tab water without any antifreeze. If the outside temperature should fall below 3 degrees, water is circulated and kept at a temperature of about 3 to 5 degrees, using heat energy from the boiler. This would cause a loss of heat energy of a few Euros at worst during the winter season, but it will save very much more on antifreeze.

One more mirror was sold to Germany.
