===**Till today we are manufacturing electricity using coal, thermal, gas, neuclear ,,etc.** ===

===**As of year 2010 approximately 1800 high rise buildings in Toronto exists.And around 280 of more planned to come up in next few years.Canada is immigarting country and most of immigrants select toronto as their destination to leave.As population increases water & power demand will be increased.Researchers are looking to generate enviornment friendly electricity. Reachers paper informed us about problem for electricity in future. We have to use neuclear power station for cheaper power. In today's world electricity is going more costly, so people are finding new way to save money.** ===

__Water Usage Data of toronto__

 * Average daily water demand: 1,312 ML/day… more than enough to fill the Roger’s Centre (former Skydome)!
 * Residential water usage accounts for approximately 51% of water used in City
 * <span style="font-family: Arial,Helvetica,sans-serif; margin: 0.5em 0px 0px; padding-bottom: 0px; padding-left: 3em; padding-right: 0px; padding-top: 0px;">Toilets are the #1 indoor water users – they account for 28% of total indoor water use (100 litres of water/day).

Now a days people are using waste water energy for heating cold water. People are using earth energy. People are using wind solar and bio diesel, etc.. In this project our target is using drain water to generate power. today drain water is going into suwage without usage of it.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">A: **Estimates vary, but each person uses about 80-100 gallons of water per day. Are you surprised that the largest use of household water is to flush the toilet, and after that, to take showers and baths? That is why, in these days of water conservation, we are starting to see toilets and showers that use less water than before. Many local governments now have laws that specify that water faucets, toilets, and showers only allow a certain amount of water flow per minute. In fact, if you look real close at the head of a faucet, you might see something like "1.5 gpm,", which means that the faucet head will allow water to flow at a maximum of 1.5 gallons per minute.**===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**Any hot water that goes down the drain carries away energy with it. That's typically 80–90% of the energy used to heat water in a home. Drain-water (or greywater) heat recovery systems capture this energy to preheat cold water entering the water heater or going to other water fixtures.** ===

===||

|| || Illustration of a drain-water heat recovery system. Water flows from a faucet down the drain, which is wrapped with a copper coil called a heat exchanger. Cold water flows through the coil and is heated by the warm water going down the drain. The heated water in the coil then flows to the plumbing fixtures and the water heater, where it then flows through the faucet and is used as drain water to heat new clean water flowing through the system. ||===

<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">How It Works
===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**Drain-water heat recovery technology works well with all types of water heaters, especially with demand and solar water heaters. Also, drain-water heat exchangers can recover heat from the hot water used in showers, bathtubs, sinks, dishwashers, and clothes washers. They generally have the ability to store recovered heat for later use. You'll need a unit with storage capacity for use with a dishwasher or clothes washer. Without storage capacity, you'll only have useful energy during the simultaneous flow of cold water and heated drain water, like while showering.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**Some storage-type systems have tanks containing a reservoir of clean water. Drain water flows through a spiral tube at the bottom of the heat storage tank. This warms the tank water, which rises to the top. Water heater intake water is preheated by circulation through a coil at the top of the tank.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**Non-storage systems usually have a copper heat exchanger that replaces a vertical section of a main waste drain. As warm water flows down the waste drain, incoming cold water flows through a spiral copper tube wrapped tightly around the copper section of the waste drain. This preheats the incoming cold water that goes to the water heater or a fixture, such as a shower.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**By preheating cold water, drain-water heat recovery systems help increase water heating capacity. This increased capacity really helps if you have an undersized water heater. You can also lower your water heating temperature without affecting the capacity.

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**RenewABILITY Energy Inc, manufacturer of the Power-Pipe® Drain Water Heat Recovery (DWHR) system, Reid’s Heritage Homes and Union Gas has completed the installation of 250 Power-Pipe DWHR Systems at the University of Waterloo, Columbia Lake Village North Community (CLV), Ontario.Reid’s Heritage Homes, in partnership with the University of Waterloo, maintains the university’s residences and has been installing DWHR systems in many Energy Star and LEED-certified residential communities and retrofit projects in London, Guelph and Port Elgin. DWHR preheats cold intake water with warm or hot drain water prior to entering a standard water heater or on-demand water system in residential and multi-residential applications, significantly reducing water heating costs and energy usage.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**Natural Resources Canada reports that water heating is the second largest energy use in Canadian single and multi-residential properties. The 20-30 per cent reduction in water heating translates to a six to nine per cent reduction in total energy usage.The typical Power-Pipe® DWHR unit will reduce GHG emissions by about 200 kilograms/person/year when displacing natural gas water heating. In a four-person home, that amounts to a reduction of almost one ton of green house gases per year per Canadian household. For the University of Waterloo units, the impact will be even greater, noted University of Waterloo graduate and RenewABILITY Energy Inc President and CEO Gerald Van Decker.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">The cost of heating water **is usually the second-biggest energy expenditure in a multi-unit residential building, exceeded only by the cost of space heating.**===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**As building envelopes become more energy efficient, the cost of water heating grows as a proportion of overall building energy load profiles and costs. Currently, nearly 90% of the heat energy in warm drain water is wasted down the drain. In terms of overall annual energy expenditures, this has a significant impact on a building owner''s budgets. Considering the lifecycle of a building, the cost of this wasted energy is enormous.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**The Power-Pipe® Drain Water Heat Recovery (DWHR) System is a proven and effective means to __immediately reduce building water heating costs by 20 to 40%__ and to continue saving throughout the entire building lifecycle.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**The Power-Pipe is simple to specify and easy to install. With its exclusive patent-pending design, it is the only heat exchanger that efficiently allows for up to four apartment or condominium units to be plumbed on a single Power-Pipe unit, without a discernible water pressure loss.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**Technically known as a falling film heat exchanger, the Power-Pipe is based on a fundamental physical principle called the "falling film" effect. Water falling down a vertical drain stack does not run down the middle of that stack, but instead clings to its inside wall. This creates a thin "falling film" from which the all-copper Power-Pipe can readily recover heat energy.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**Built of quality materials and with no moving parts, the Power-Pipe System is simple, effective, foolproof, and maintenance-free, with an expected service life of more than 50 years.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**The Power-Pipe''s performance has been verified by Natural Resources Canada, the University of Waterloo, as well as other American and Canadian agencies and power companies, in independent third-party testing. The Power-Pipe''s proven technology is presently at work in many multi-unit residential projects, including condominiums, apartment buildings, affordable housing developments and university residences.** ===

===<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">**With its low initial cost and ability to __recover up to 40% of the heat energy that is otherwise lost__ in drain water, the Power-Pipe helps building owners realize an attractive return on their investment, with a full payback typically in 3 to 4 years. In addition, the Power-Pipe qualifies for energy efficiency financial incentives available from numerous governments, as well as many power utility companies.** ===

<span style="font-size: 1.1em; margin: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">In short, the Power-Pipe:

What if we drilled a very deep hole into the ocean (down to the extremely hot farthest reaches of the crust where water will evaporate easily) and set up a generator at the bottom? Have a massive pipe connected from the ocean water to the bottom of the pit. The hole wont fill up with water if ventilate the steam to the air above the ocean (driven by the difference in pressure). Mineral Insulated cables could be run down to the generator. I'm talking extremely hot conditions here to allow the massive amount of water flow to evaporate ASAP.. we would actually be using the earth's heat as a driving force to return the water...** ===
