Can bicycles be a sustainable means of transit? Absolutely, but we've got to think differently about getting, using, and repairing them.
Low Tech Magazine's close look at supply chains and bicycling is interesting and might convince you to find or fix up that old steel frame rather than get the newest cheap aluminum one.

George Cove, ein vergessener Pionier der Solartechnik, hat vermutlich ein sehr effizientes photovoltaisches Panel entwickelt, 40 Jahre bevor Ingenieure aus den Bell Laboratories Silizium-Zellen erfunden haben. Falls sein Design funktioniert, könnte es zu weniger komplexen und nachhaltigeren Solar-Paneln führen.
Heeft George Cove, een vergeten pionier op het gebied van zonne-energie, een efficiënt fotovoltaïsch paneel gebouwd aan het begin van de twintigste eeuw? Als blijkt dat zijn ontwerp werkt, kan het leiden tot minder complexe en duurzamere zonnepanelen.
We built a pedal-powered generator and controller, which is practical to use as an energy source and exercise machine in a household -- and which you can integrate into a solar PV system. We provide detailed plans to build your own, using basic skills and common hand tools.
George Cove, a forgotten solar power pioneer, may have built a highly efficient photovoltaic panel 40 years before Bell Labs engineers invented silicon cells. If proven to work, his design could lead to less complex and more sustainable solar panels.
