Where do you mount this contraption? Solar PV is light enough for any roof - otherwise wasted space. You probably have to mount this on the ground unless you want to spend a ton of money reinforcing everything.
- dghughes 10y agoHere is eastern Canada pitched rooves are capable of withstanding about a metre of snow. Wet snow supposedly has a mass of close to a tonne per cubic metre, a cube of pure water is one tonne at 4C. I can't imagine these devices would weigh more than a tonne (1,000 kg) per square metre.
- mangeletti 10y agoI think there is a bit of a communication breakdown here. @todd8 is simply stating that the sphere full of water would be too heavy for this to be a serious proposal. @dghughes is basically replying, "Look, it says so right here. That's their plan." They're not arguing over the material to construct the sphere. It is merely incidental that there was conflicting information in each of their comments.
