Water-saving technology for the home includes: Low-flow shower heads (sometimes called energy-efficient shower heads as they also use less energy, due to less water being heated). Low-flush toilets, composting ...
... is a black balloon that is filled with ordinary air. As sunlight shines on the balloon, the air inside is heated and expands causing an upward buoyancy force, much like an artificially-heated hot air balloon. ...
