Drain Water Heat Recovery - ThermoDrain and EcoGFX

I love Wind energy, Solar energy and geothermal energy but simply cannot afford it.



Here is a challenge for you.

Find me a 10kW hot water heater that......
1) Lasts 50 years and requires no maintenance
2) Is 100% recyclable
3) Uses waste energy to produce its own (not powered by new energy)
4) Is 55% efficient and costs between $500 and $600
5) Works only when I need it
6) Allows me to reduce my original hot water tank by 50%
7) Increases my shower time capacity by 3x (example: 40 gallon tank will give me 30 minutes of the shower time and when this "hot water heater" is installed it gives me up to 90 minutes)

Submit your ideas.
