Reclaiming energy from waste water in tall buildings

THINK OF IT AS…Bath water-generated hydroelectricity. This system uses gravity to make electricity from rainwater, grey water and black water as it exits tall buildings. With every flush or turn of a faucet, water rushes down into a turbine, generating power and making you rethink your next goldfish funeral.

World’s first hybrid wind/current generator could generate double the power | Treehugger
Combining a three-bladed Darrieus turbine on top, a Savonius turbine underneath, and a generator in between, the SKWID power generation concept is claimed to be the world’s first hybrid system “capable of maximizing the harvesting of ocean energy from wind and current”.

This High Concentration Photovoltaic Thermal System (HCPVT) can harness the energy of 2,000 suns and provide fresh water and air conditioning in remote locations. The prototype HCPVT system under development uses a large parabolic dish, made from a multitude of mirror facets, which is attached to a tracking system that determines the best angle based on the position of the sun. Once aligned, the sun’s rays reflect off the mirror onto several microchannel-liquid cooled receivers with triple junction photovoltaic chips — each 1x1 centimeter chip can convert 200-250 watts, on average, over a typical eight hour day in a sunny region.

Harnessing Heat from City Roads | ThisBigCity
The black asphalt roads of urban centres are notorious for soaking up the sun, often helping make cities uncomfortably hot during the summer. Special piping technology from the Worcester Polytechnic Institute in Massachusetts, however, is offering a way to trap this heat and use it elsewhere, potentially transforming urban streets into giant solar collectors.
The idea is simple: the sun-warmed asphalt can be used to heat up water, which is pumped through tubes embedded a few centimetres below the road surface. This has the dual effect of cooling the asphalt, prolonging the lifespan of the road, and heating water which can be used either as is, or to produce electricity.

A (Dimming) City of Light | Scientific American
The French are taking a stand against light pollution. Starting this summer, most non-residential buildings in the country will have to shut off their lights at night in order to “reduce the print of artificial lighting on the nocturnal environment.”
According to France’s environment minister, Delphine Batho, this shift will reduce total annual energy consumption by the equivalent of 750,000 households. But, the main motivation behind the new decree is public health. According to Ms. Batho’s statement, artificial light can cause “significant disruptions on ecosystems” by disturbing sleep and migration patterns.
