Could this help with the current energy problems?
Answer:
the production, installation and maintenance costs would outweigh any possible gain.
first consider the price of the mini dynamo's, a small electric generator coupled to a waterwheel in a inline pipe, lets assume you can manufacture them fairly cheaply and they only cost £10 each, adding one before each tap in a normal house (1 kitchen, 1 bathroom) costs £40-60 in materials (bath taps, sink taps, kitchen sink taps) then require wiring to a battery charger (at best the power gained from these would be a trickle charge on one battery), Labour costs for 4 hours installation work (should be sufficient to do all 6 taps) at £40/hr = £160.
total cost £200. assuming maintenance free units you can expect them to last for 3-5 years before needing replacement, so £200 every 5 years to have a battery charger. = £40/year = £3.33/month = 76pence/week.
No
cos the energy you could take out would have to be put into the system somewhere with more pumping and cos the efficiency of everything is less than 100% you end up losing out all round
the only energy you can usefully get frorm waste pipes is the heat energy
i dont know but at least ur actually coming up with some good ideas a lot more than some other people are
keep up the gr8 ideas

i was thinking this but if you think the cost to install this item and the cost to buy the item. It wouldn't be worth doing. BUT if you was to install this in the main water pipe where the pressure is high and the flow rate is very fast then that would be a great idea. Still who is going to foot the bill to the design and then installing and who will make the profit from the energy.
This country is good at asking people to try and find way's around a problem but no company wants to foot the bill and why should the people. The people won't be the one's making the savings.
Still great idea.
I don't think it would be cost effective or generate much energy. The main excess energy we can use if from the heat we generate, that can be stored and recycled.
But a good idea, worth a star.
Keep on thinking.
Good idea but not that effective you would have to put tiny water wheels though out the water system and increase the pressure it would help in reducing individual energy bills but I wouldn't think it be cost effective.
energy always costs something, no energy is free to be created. The dinomo would slightly increase the resistance on the line, haveing every household haveing increased resistance of water flow would force the water works to increase there pressure, which uses more electricity on there end with the pumps, witch all balances out to be equal to not useing any dinomo's
If there is such a thing as "free" energy, water pressure is not it. Water pressure is what it is on the incoming water side to ensure that water flows a the outlet in an outgoing direction. In the waste water side of a system, it must be unimpeded to prevent backup.
Putting something in to harness flow for the sake of generating electricity creates resistance. This means it would be possible for contamination to intrude into the fresh water system and waste water might not properly flow.
And consider the source of the water pressure you are seeking to harness: That water pressure is generated by some type of motor that would have to work harder. Due to losses in the pipes and inefficiencies, you'd generate less energy than if you connected directly to the motor generating the water pressure. And if you did that, you're doing what the electric power company is doing anyway, and in all probability you're doing it with less efficiency.
