I should have clarified re indoors: My comment was about setups like in the article, which are reliant on electric lights. One of the biggest limitations they have is electricity cost.

You can build head with a windmill, but moving water (gpm) requires horsepower.

Also: LEDs are very efficient vs other types of lighting.
