Harry visited LUT in order to deliver two lectures on steels and to discuss research and teaching with the staff and students in the Department of Engineering Sciences and Mathematics.

At LUT - the cars are plugged in to electrical outlets.

These are electrical connections for parked cars to keep them warm. Temperatures were between -8 and -15 C.

LuleƄ is located in the northern part of Sweden. There is a lot of snow that falls during winter, when the temperature is significantly less than zero centigrade. Sufficient snow is collected by lorries and piled up so it does not melt completely even in summer. The snow mountain is used, via heat exchangers, to cool the equipment at the Lulea University of Technology.

Tree hotels at Harads, about 80 km from Lulea. A variety of "rooms" available, all but one clinging to trees. Esa Vuorinen, Lars-Erik Lindgren and Harry visited the forest where the hotel is located. I think that winter is teh best time to stay there, with absolutely beautiful snow painting the picture. The snow is dry because of the constant sub-zero temperatures. With sunshine, it is as if a million diamonds are scattered amongst the blanket of white. Getting poetic here.

This was our expert guide.

This tree-house seems to be made of Corten steel.
