was founded at 1 Pesotskaya Ulitsa, St. Petersburg by Adolph Müller. Portable Energy The Tudor brothers from Rosport lived in a rural environment which they wanted to open up to scientific and technological progress. In August 1884, they connected an electric motor to a threshing machine in their father's barn. The energy was fed through cables more than 60 metres (200') long. The first eyewitnesses could not hide their enthusiasm. The issue of carrying electrical energy to remote countryside locations remained. It was not until 1905, at the Liège Exhibition, that Henri Tudor and the engineer Maurice Braun were able to display a possible solution, designed as a replacement for the traditional portable engine. The cart, which they called an "Energy-Car", was compact and carefully designed. It consisted of an internal combustion engine, a generator, a lead-acid battery and the instruments required to control its operation. It was not a self-propelling vehicle. The device was first built in the Rosport factory, and subsequently at the Braun workshop in Brussels. The Energy-Car was not a commercial success. The purchase price and maintenance costs were high, and its operation was not straightforward for the uninitiated. A few years later, with the advent of rural electricity grids, the electric motor became predominant on farmsteads, and the Energy-Car became obsolete. Recognition The Tudor brothers may be considered as the "industrial followers of the theoretical work of Planté". In 1987, CRP Henri Tudor (the Public Research Centre Henri Tudor) was founded in Luxembourg, and named in honor of Henri Owen Tudor and his devotion to research and innovation. On 12 May 2009, the Luxembourg Post Office issued a set of three stamps on the theme of "Eminent Luxembourgers". One of the stamps depicted Henri Tudor. In 2013, the minor planet (260886 Henritudor), discovered in 2005, was named in honour of Henri Tudor. The Tudor Museum in Rosport The house of Henri Tudor is now a museum. In December 2006, the Aldermanic Council of Rosport, consisting of Romain Osweiler, Henri Zeimetz and Patrick Hierthes, published specifications for a "modern and lively museological space focusing on energy and energy storage". The new museum was to concentrate on the inventions of Henri Owen Tudor and their impact on industry, as well as on the man himself, his life, his family and his links with Rosport. The bid from Wieland Schmid from the Mannheim Design Studio caught the eye
