Check out the Arc shower system that brings something totally different to your oasis of relaxation in your home – it will turn a standard “shower mode” to an “energy-saving mode” without missing a beat. All warm shower water on the spot will be recycled, alleviating your guilt whenever you indulge in a nice, warm bath – even better if you use a solar-powered heater, of course. If it ever gets off the production line, then we suspect this will cost an arm and a leg to purchase.
