This Idea Wasn't All Wet: The Sensing Water-Saving Shower Head Debuts

Cars That Think

He imagined a shower head that would sense when the person showering moved out from under the stream of water. The shower head would then automatically turn the water off, turning it back on again when the person moved back into range. With such a device, he thought, people could enjoy a long shower without wasting water.

Perspective: Drive Star Conversion Program Could Cut US Oil Use in Half by 2020

Green Car Congress

Even on land, getting oil from tar sands depletes water and other resources and doubles oil’s carbon footprint. We’ve already decided we’re going to fix already-built houses, offices and factories that waste energy. Cash for Conversions” will start by fixing many of our 100 million trucks, vans, and buses.

The home is also three times more water-efficient than a typical US home. All of the energy for space heating, space cooling, ventilation, lighting, hot water, appliances and consumer loads, in addition to the transportation energy for the Honda Fit EV, is supplied by the solar panels on the home. Water efficiency.
