comment Nobel prize for (dangerous) LED lamps?
This question doesn't seem to be about physics concepts at all. It might be ok on Sustainable Living, Skeptics or Biology

comment What is considered 100% efficiency when talking about photovoltaic cells?
@Passiday There's a theretical maximum at 86.8% - dx.doi.org/10.1088/0022-3727/13/5/018

comment Is there a scientific/physics mistake in my idea?
I think there are several questions that could help tease out the issues, and you're welcome to ask these one at a time on Sustainable Living, and see if the answers help you, before asking the next one. See also related renewable-energy questions here. You might ask why commercial wind turbines have settled on the 3-blade HAWT, when other designs seem to offer higher efficiencies. You might ask how PV has become so globally successful, despite only having efficiencies of ~15%. Perhaps ask why Savonius turbines work in the lab and fail in the market.

comment Is there a scientific/physics mistake in my idea?
What is the physics concept you are having difficulty with? Please edit that in the body of your question here, rather than expecting people to follow a link and find the relevant bit that's hidden in some drop-down section. And if you want to ask questions about the specifics of engineering and economics of renewable energy design, then Sustainable Living is the place to ask: having read through your google science proposal, I think the issues aren't about physics, but are instead about engineering and economics.

comment Determine the number of days with North-East wind direction from the number of days with North and East wind direction?
What is the actual problem you are trying to solve? Are you sure that the dataset is as you describe, or is it a set of wind components in the U (E-W) and V (N-s) direction, which is standard for weather data?
