SOLAR IS NOW SPREADING TO OTHER AREAS.

Solar panels are being rolled out “like carpet” on railway tracks in Switzerland.
Swiss start-up Sun-Ways is installing panels near Buttes train station in the west of the country in May, pending sign-off from the Federal Office of Transport. As the climate crisis demands that we speed up Europe’s energy transition, developers have been seeing new potential in unusual surfaces. Roadsides, reservoirs and farms are all finding space for solar systems. And Germany’s Deutsche Bahn is also experimenting with adding solar cells to railway sleepers. But Sun-Ways is the first to patent a removable system, with the help of EPFL, the Swiss federal technology institute in Lausanne. It’s a crucial one since railway tracks need to be cleared from time to time for essential maintenance work. The Swiss company, based in the western town of Ecublens, has devised a mechanical system to install its removable solar panels. A train developed by Swiss track maintenance company Scheuchzer will travel along the rails, laying photovoltaic panels as it goes. It’s just “like an unrolling carpet”, says Sun-Ways. The specially designed train uses a piston mechanism to unfurl the one-metre-wide panels, pre-assembled at a Swiss factory. Electricity produced by the PV system will be fed into the power grid and used to power homes as feeding it into railway operations would be a more complicated process.

    Fantastic blog! Do you have any helpful hints for aspiring writers? I’m hoping to start my own blog soon but I’m a little lost on everything. Would you recommend starting with a free platform like WordPress or go for a paid option? There are so many options out there that I’m totally overwhelmed .. Any recommendations? Thank you!
