As if to make up for the modern tokenisms at the church, Guido leads the way to another new-old temple of change perched over the four main upper Engadin lakes&mdashSt Moritz, Silvaplana, Sils and Champfer. Trundling up in a bright red funicular, our portly Santa Claus-y guide tells us the vantage point of Muottas Muragl and the now energy-plus Romantik Hotel is about 4,000 steps on foot. At the top, conversation runs as thin as the air. Not because the sweeping views of the valley leave one breathless&mdashas they should. But because the north wind picks up and finds us cowering in a snowbound cabana, drinking deep from a borrowed hipflask. When the wind finally forces everyone indoors&mdashabandoning plans to follow the Philosopher&rsquos Trail up to the cottage of the artist Giovanni Segantini&mdashthe sun shines again, this time in a PPT. A proud proclamation of the fact the 110-year-old Romantik Hotel may now be poorer by 20 million Swiss Francs, but it is richer by 1,00,000KW/jahr solar energy. North wind notwithstanding.
