1. run a hose to the roof of your house
2. keep a 1 cubic meter tub full of water on your roof
3. let that water drain through a tube to the ground
4. put a water wheel in the flow for a motor
That will provide enough electricity to run your whole house.
i have a turbine with massive power ... i built it is a alum tesla turbine ... i was really surprized when i first ran it years ago .. it whipped the axel right round ... from a garden hose ... even turning an old 6vdc car generator from the 50's ..
regards ..

Sorry but it would be a very bad idea to put a cubic meter of water in a container on almost any roof. That much water would weigh over 2100 pounds not even counting the container. That would fall through most roofs as they are generally designed to hold the weight of the shingles and a person on them walking carefully. 2100+ pounds in one area of a roof would be a disaster waiting to happen unless a lot of extra bracing was put in place including bracing within the house below the roof.
Even that amount of water would not provide electricity for long using a paddle driven generator. Sorry to nix anything that is an alternative power source but it's just not a good plan in it's currently presented format.

Sorry, you won't be able to generate enough power to run a pump to pump the water back up to the roof.
Also consider that most homes that have a city water supply will find their billing quite low for average use of water. But when it gets over so many gallons the price goes up a lot. My assumption has been this is to PREVENT people from using water to generate electricity.
Ah......
This is a forum than Nixes free energy ideas.
I see.
You will need water constantly falling, to have your generator constantly running. Your water bill will be enormous.

No, it doesn't. It sheds light to stop people wasting money on
hose pipes if they will get you nowhere.
The answer lies in your trying it out. A local school might have
a Physics teacher who would love to turn this into a project
for his pupils.

That's not a bad idea.
A home needs ~45,000 watts/day.
If my math is correct, that wattage is achievable at a flow rate of ~.04 pint/second.
Using fairly expensive water rates, that's <$100/month.
So if your electric bill is more than that, this seems cost effective.

=>A home needs 45,000watt hours per day. I calculate 36KWatthours at my
stated 1500Watts continuous. So you are close on that *if* your units were right.
At that rate 1500Watt seconds per second .04 pints per second sounds low.
this is about at 760watts= 1HP about or about 2HP horsepower. A horsepower
is 550foot pounds per second or 1100foot pounds per second. If the house is
10 ft high 110 pounds per second water weights 8.35lbs gallon = 13.2 gallons
per second. Slightly more than claimed at turbine efficiency of 100%.
Excluding any overunity of course. :) At 792 GPM =~ 2 Cubic feet per second.
13.2gallons per second * 3600 *24 over 1.1Million gallons per day!
That sounds expensive...Billmehess's water battery is a better deal.
a salt water battery and a jt powering my kicker board will give much more and cost much less ..
lol
or earth battery or solar
if you can afford boost caps you can get massive power out of the unit ..

If we could get the tank on the roof to fill up with rain water that the Sun lifted during the day and deposited in the tank at night then it would be a good idea. Someone actually holds a patent on creating a permanent location for a cyclonic storm. The currents passing through turbines on their way towards a permanently maintained low pressure center in the middle of the turbines. Possible use for Stonehendge. The giant red spot is thought to be a permanent hurricane on that planet. A hurricane is like a giant conveyor belt that uses stored up heat in the ocean to make the air rise where it is cooled becomes more dense and falls back to Earth. The difference being that momentum builds in the vertical circulation with one side of the wheel having heavy rain falling connected to the other side of the wheel that has warm light vapor rising. The bottom of the wheel sweeping across the heat scource and the top of the wheel sweeping across the cold scource. A natural stirling engine.
Well if running the water to the container on the roof is able to produce energy, then maybe just use the water pressure from the line to run a gen then output to the sprinklers. Get paid to sprinkle on the utilities tab.

But then again, by running the water to the roof is using more energy to do so along with the water that you are being charged for. So run it to the roof, then run the gen, then store the water for use later, or just sprinkle the lawn. There is energy there for the taking.
Mags
Tesla turbine is the way to go. It will not create a pressure drop like a standard positive displacement turbine. It works off the flow alone not the pressure differential. This way your sprinkler heads will still have the same amount of pressure differential. This is how dumb some people are. They just built this huge dam in asia. They displaced umpteen people and interrupted farming and fishing operations for an entire valley so they could build this giant fucking dam when they could have just put some Tesla turbines in the river and everybody could still be doing their thing. This prooves the electrical concept also that current can do work without dropping voltage.
This could be a part of the picture along with wind and solar. Just put the turbine in your incoming water line. Every time you flush the toilet or take a shower,wash clothes,etc..your making electricity.If you lived in a large apartment complex you could be making electricity all the time. Hey why didn't I think of that...I have a school across the street from me I wonder if they would let me stick a turbine in their water line..lol.. I'll sneak over at night..yeah that's the ticket..
Looks like I underestimated the amount of A required to run a household. If elevated 10 feet, you need ~25 gallons/second. That sounds incredibly high to me, but that is the number all the hydroelectric calculations arrive at. My real point of this thread was partly to point out a different way of looking at things.
So... is there a way to get 25 gallons/second of water to go up 10 feet without a pump or electricity?
You could always work a deal with the water company. They pump it up to you and you run your turbine generator and store the discharge water in your loft tank. (what the heck is it with tanks on and in the roof lately) Then they shut their motors off and you let the water stored in the tank go back through the line to spin their turbine so they can get a little of their juice back. Of course let the water go backwards through your turbine 1st so you get a little juice on the back feed too.
So far, the plan looks (do-able) good to me.
But,,,I am also thinking their might be a snag.
Sounds too simple.

@All,
Actually, I have to admit, using a Bernoulli
aspiration pump you can pump 6 gallons of
recycled water to the roof using only one
gallon of utility pressure water. The water
tank could be on or under the ground. So
that cuts water use to 1/7 of that calculated,
if you really *want* to do this. That's still
a lot of garden hoses worth though! (After
all this *is* overunity.com ;))
Google "pumps a lot" or "miracle mini pump"
I assume the Op was posted for those of us with their own wells.
Interesting topic. You have had some very intelligent input to your idea. I like a combination of some of the ideas posted here. Place a small turbine in you house or apartment water line near the input and use that to pump water from a tank on the ground, to a tank on a raised platform. (not the roof) The water in these tanks could be continually recycled except for evaporation losses but, you would also get some rain input so the volume would not decrease that much.
Now, as the other fellows pointed out, you could not afford to run the pump all the time but, when you use water in the home for regular purposes, a volume of water would be transferred from the ground to the raised tank. Add a few solar cells to run a dc back-up pump and possible a 3rd power source of some kind, possibly wind, and now you might be able to use these 3 sources to keep the raised tank nearly full and run your turbine in an almost consistent manner.
It still might not be cost-effective yet but it might be a bit closer.
Always good to think.
Bill
I would eliminate the water over the house, insurance is already too expensive and picky.
I would get a large round pool, use a high power electric snow blower motor (run with solar panels during the day) with a stirrer blades and create a stationary whirlpool. The mass of the spinning water would turn a bladed VAWT generator which would be placed in the center of the vortex where the flow is greatest. You would need a lot of water, the more mass the better.
If you ever made a whirlpool in a pool as a kid you would know how much force going against the spinning water is.

Okay then, how about this idea. I live in the SF bay area, where the weather patterns exactly match your idea, Sparks, at least in the cold months. We get most of our rain from november to May, and it comes at night, after it gets dark, and it rains like blue blazes. With a roof tank that was very spread out to distribute the weight, it would certainly power a turbine, at least for half the year.
I was also thinking about having a receiving tank for the water, since with the rain the garden certainly doesn't need it. If the tank had an open pipe outlet running up to the roof tank, overflow would enter the tank to fall and power the turbine again. Or so I'm thinking.
