There's been lots of talk in Troubled Times about not relying on solar energy because of lack of sun. However, we continue to talk about the need for artificial light to grow plants. Here's a reality: If we're able to generate artificial light then solar powered items are quite viable. In any sort of greenhouse scenario, you need aisles to maintain plants. While you're not using these aisles for your feet, you can populate them with solar paneled rechargeable devices that could even feed back into the system powering the light in the first place. My latest Jade Mountain catalog (800-442-1972), has unbreakable solar panels. While I agree it can't be the primary source of power, it can certainly recycle light generating from another power source such as wind.
