Great Job! Micro-Hydro has virtually no impact on the environment and the river flow. My minor in college was hydro-power. It’s awsome! Many installs can be housed in tiny sheds that are almost hidden. The local fly fishermen often bragged about this one portion of the river. For decades, few were aware that it was a tailway for a three turbine plant built in 1924! Three horizontal Francis turbines generating about 35 KW each. FO Stanley was famous for his steam cars and the hotel featured in the movie The Shinning. Few knew of his power plant. They drove past it on the way to the national park but few realized it was an operating hydro plant. It was online continuously from 1909 to 1983 when a damn break wiped it out. The dam was an irrigation dam not related to the power plant.
This is why I jokingly refer to the Tesla as my favorite coal fired automobile!!!!!!
Long Live Micro Hydro!!!!
With you sir my dream have come true I love this am from Nigeria
I will support you for this. I’m also a hydropower specialist
Yes there s a lot of clean energy we can have, in every small river, in windy places and sun heat.
Good opl like this will hopefully have this world! This man should not feel the need for anything! For he work he has done. I would like to personally thank him for his efforts. I hope they are 1000's more to follow in his foot steps!! I only wish I had enough water to run a hydro generator!
Thanks for all the good comments, yes two- or even three tiered pricing is the only way to create a sound financial footing for green power. As for waves...ocean currents... send me story ideas and I will cover them.

That's really great stuff. Unfortunatly you are right about state subsaties, consumers have been getting artificaly cheap electricity for years. We could only sell the electricity from our hydro by selling it to the public electricity companies and they would only pay for the avoided cost ie. that extra shovel of coal they didn't need to put on because of our generation. This meant we ran our hydro on very little income for about 20 years. At long last we are getting a fair price now.
Great documentary...this is the way forward for Africa to develop, especially in those regions near the Zambezi and other mighty rivers. Will be contacting you shortly Pat, as we need something like this for Tilapia farm we're looking at establishing next to the Zambezi in Mozambique
Hi Pelton,
Thanks for the insightful comment. Yes the end of state subsidies for Coal power and other environmentally damaging power generation technologies is a great thing. Next it would be nice to see a higher-than market price for locally produced power from renewables. Which makes sense since they support and benefit infrastructure and lower costs across the grid. Imagine a time when the Grid becomes a massive battery. Do you have links to some photos of your system? You also in SA?
Hi hillbilly,
Thanks for the comment though not sure about your point, since Hoover Dam supplies the energy from Hydroelectric generators for the Nevada city of Las Vegas. However if your point is that Las vegas is a dramatic illustration of over-consumption and waste of hydropower energy, then I wholeheartedly agree.
I am with you man micro hydro are the best option for this planet

your great sir, i think that's your life, keep it up sir jefftube,
we need more clean power like this
Live in 'Vegas, We only get a small fraction of the dam's output. We have coal and solar plants (Mostly coal) producing the rest. Most of the power from the dam goes to Phoenix and LA..........
looks like double trouble on the fish river .i do safety there every year love your set up nice on keep it up
Great video. Unfortunately, hydro power generation does not work just anywhere. I live in Victoria Australia, and although we have a large number of fast flowing rivers in the North-East of the state, flow rate diminishes during our summer months. NSW has a huge hydro-power system in operation fed by the melting snows from lake Jindabyne in the Kiewa valley. Cheers.
Yes, not a universal solution. Tax the life out of coal and oil and use it develop modular Thorium molten salt reactors I say.
Nice video and I agree with most of the sentiments although,when I was in Capetown I was stunned that there was almost no sign of solar power systems despite there being lots of sun. Surely there is a business opportunity there?
clean, green, inexpensive, easy to maintain, practicality, 24/7 (unlike solar) and happiness! ^_^
Very nice video! Like it!
Nice
I hope to built many in my country!
use a chamber which is uplift the water from stream and we can draw the water regularly
Well done !!
great work on developing electronic load controller,..as without it wont be economical,.i hope u did lot of work in those 9 months for developing that electronic load controller,.that to with limited resources,.great job,. i too had designed a electronic load controller using microcontroller,.im happy to share informations on this topics to any one,.
This is excellent. Is the governing system load diversion or is it water flow reduction? Water flow reduction for off peak would be the magic trick everyone is looking for.
this is a load diversion system to dump the excess power. for water flow reduction we would need a mechanical governor to regulate water going through the turbine runner. this is a complex system that is not needed for small hydros as it requires complicated PID control
@@martinkingori9598 Yes I understand. It was a bit ambiguous in the video. If it was a flow reduction type, it would certainly get my attention. I would certainly want to see how that was achieved in a micro system. I don't think the response time would be sufficient in a micro system since demand changes can be sudden going both ways.
@@nez3009 i also feel that the load diversion type is a waste of energy.In such arrangements that i have seen, most dumploads are heating elements..the users end up having tanks of hot water that they don't require..furthermore the turbo generator is always on full load imposing larger mechanical loads on bearings..wear and tear is much quicker
@@martinkingori9598 I agree. I live in northern NY and have a hydroponic system with cast iron rads so there is no such thing as too much hot water in the winter. Never the less, I think with the right engineering/testing, something can be designed to regulate flow on a micro system. I think having some kind of battery would go a long way for rapid spikes and demand decreases.
I have the same vision for my country!
The primary purpose of any large scale dam is flood control and water storage. The hydro power is just a bonus.
The coal industry needs to start paying for their true costs caused by pollution, and the oil industry needs to start paying for all the military costs needed to maintain the foreign supply chain.
What if there a drought?
cool vid this guy called Watt likes water power i recall
use siphon for production of electricity forever
siphon gives extra atmospheric pressure so we have more energy density
lvery best idia of small hydro
everyone all the way down the river can have their own micro hydros.
Wow! I need to take a trip to Africa :P
come with all pleasure we will embrace you
Hi Simbarashe, Sorry about the jerk comment from a few days ago. I deleted it. Hate speech is not allowed anywhere near my feed, we all need to work together for the common goal of clean energy and mutual support and understanding. Onward together my brother.
thanks brother
Hoover Dam supply around 2% of the energy needed in Vegas, whatever its a waste or not.
use running water energy at it's maximum potential and used it for steam boiling water
so we know that water going boiling at 100 degree celsius now we turned the turbine with help of water steam
so we got more efficient and effective control over the stability of voltage production instead of loss of energy in electricity circuit and very much costly technology infrastructure
happiness is not the costly technology infrastructure we. can use this property of water on e every planets of universe by applying automatic setting of pressure on the system
💠💠💥💢
Wow
Have you thougt about the tidewater in the BIG ocean?
Why does the generator need a governor? I could understand on windmills so they dont go too fast and explode, but why a water turbine?
Pretty much same reason, also to keep from going over voltage and harming whatever is connected to it.
เสียดายพลังงานน้ำที่ไหลออกมาจากไฮโดร์ สามารถผลิตไฟฟ้าได้พอๆกันกัลไฮโดร์
in India their are so many rivers which gives energy by using hydraulic system of turbine
so gives your advice to Indian government
help the poor people world wide
we can produce endless amount of energy through sea water hydrolysis .then we take hydrogen alone to high altitude ,where we combine it with atmospheric oxygen, and drop the formed water on hydraulic turbines as in dams.
#1 What would you use to power the hydrolysis? Hydropower? This idea seems to be a perpetual motion scheme that can't work because of the problems of efficiency.
#2 ever hear of the water cycle?
Wow,good going! Been to Texas yet?😀
Nuclear is actually the safest energy source we have. Sadly it is for ever associated with bombs and that stigma has increased costs and stopped innovation.
how much power could i produce with a small waterfall that produces 70 gallons a minute and drops 17 feet to the4 ft water wheel i have made? and what kind of turbine would be best to use
880W but at realistic efficiency it is 528W.
Not sure how to calculate a water wheel though you will probably get less.
ben lawton what would be the best turbine setup do you think would be best
Daniel Bradford yes turbine is better since you will be using all the head
Daniel Bradford you won't get very high pressure though since it is only 17 ft
Hah. I loved how you totally owned him Jeff - But so politely
I regret to say the wasteful (I am one of them living in a electricly heated apartment) electricity dependant society the sheer scale cannot be supplied by any combination of wind, small or large hydro or solar power. A few large or many more medium size, gigawatt or hundreds of watt, central generating stations will be required.
Fortunately these do not have to burn oil, gas or coal to power the steam turbine generators that make the electricity. There is a nuclear fission based power cycle that is neither as expensive as Uranium fueled nuclear power. It is Thorium based nuclear energy. The greatest advantage of this system is it does not need a huge and expensive pressure vessel around the core. These operate the heat generating core at atmospheric pressure. The reactors can also be built in a wide array of sizes so can power smaller cities.
In the meantime in places where flowing water is available I support using as much as practical the water power available. Developing the smaller sites is easier and faster than the huge projects generally sponsored by central government's.
You are using cross flow turbines. They are simple to build and Install but are not very efficient. I suggest you look up a couple of Indian turbine manufacturer. When I was working redeveloping hydro sites I looked at one of these companies and was favorably impressed.
wow, great job, i can only understand that the energy company's are only using coal & nuclear power for profit, if a small community & town could all pay into a project, we could wipe out high cost of power, I saw a guy on you tube using a tank that store water, Then it uses the pressure of the falling water on a turbine to then let the water go back into the overflow. this would also prevent flooding, if there was too much water flowing though the river. but it would mean we would need a large amount of though tank to prevent this from happening. I came across an answerer a guy said, he said what if the water was to become too cold, well i can only think that, that you could have a small thermostat inside the tank to prevent the tank from dropping to a cold temperature. to prevent this happen. this would cost power, but would be a back up to prevent the system from jamming or braking completely as it made of plastic, "well the tank anyway". if you could have a auto system to switch this thermostat on, using the power of the hydro system to take so much power, but to limit the temperature so it would not fall to below 0c degrees. This would keep the electrical system going & only use a small amount of energy to heat the tank in the mean time. well the weather warms up a bit. then the auto thermal stat would shut off after temperature of atmosphere warm up. Given you all the full energy it generated in the first place.
Looking at the pro & con to this. solar can only give power during the day. Turbines are dangerous to human health. due to there sound & flicking shadows. Sound can vibrate though human as sound travel though solids. That why they are set up in the sea. I saw how it had destroy a town. As energy company's ask to let out your land, then you sign it without reading it because they said it was green, you understand that need money so offer you something small to pay off a bit of your land mortgage . They then build the thing all over your land. I doesn't matter to them, they can build them right next to your house then it driver you mad, i have heard & saw a family in america. they moved into a hotel because it was that bad. The flickering in the window of the turbine drove them insane. I can say they don't always spin due to the wind. That sometimes they need shut off if they spin to fast. Ice can shatter sometimes. so there no big investment to wind. there a waste of money. the cost of building them far outweigh your profit unless they can spin for 70 years. So i say here that micro hydro is a great of source energy. it has a little impact on the environment & are fairing cheap for the investment. I live in wales we have lots of river & we hardly use them what a wait of energy. sorry for the large amount of writing people. hope you all the best & thank for reading if you had chance.
Mr expert
make some mini or micro hydro turbine so we use it in heron's fountain and endless energy forever for everyone possible
You're funny
with big projects - lottasa money floating around - they like expense accounts they like the ,,,,,,,,,,,,,,,,
dear waseem there is not a big thing we also can run these plants in Pakistan
lol i don't think he readed the comment properly, what he's actually saying is that coal is the way to go but the second guy thinks hydro is the way to. also i think the water needs to be cleaner dirty water is bad not good a few trees might help with that. it will also help with the air cause it eats the carbon so you don't have to and once you have lots of trees all that carbon can be turned into houses so you can live better. it really is win win situation plant some trees!!
gosto disto
would you like to work in Pakistan on small dams
Hi we are producing turbine in Germany, from 10-10000 kWt , also make detail design . Hydroenergetica.com
What your problem
magnetic power is this best way
Hydroelectric generators like all generators use magnetism in order to create electricity.
Now if you're talking about perpetual motion machines, please show us one that actually works. There's a lot of shysters out there claiming that they've made something but haven't.
Too bad didnt show how they work
sir ur pefect!! can i meet u please!!
no
where are you
I agree coal is bad but nuclear is actually very good its killed the least amount of people than any other type.
I'm convinced that the real reason we have nuclear power plants is mainly to provide the resources for nuclear weapons.
@@johnwyman6331 no, actually not. Only few nuclear reactors in the world could provide fuel for weapons.
There are over 400 reactors.
Wat about the waste? You talk about human victims. But here nature is the victim again.
@@aaronvanhoucke2065 All that radiation existed naturally anyway and if buried deep enough is not a problem.
I hate misleading crap. Those nasty big old damns and power stations.... So scaling it down is better some how? So the big one probably serves 200,000 and his serves 20 so how many of his would we need again???? 1000's of little micros all over, that wont affect the environment?? Hey I love these micro plants but all have to alter water from the river, stream or whatever. Most areas don't have white water rapids to draw from so they build a holding pond of some sort from just a few rocks to large concrete structures. There is piping that in some cases goes for 1000's of feet to build up enough head (pressure)….
Hydropower uses dams to create the head.
Micro Hydro power typically uses underground pipes to create the head there is no flooding required creating land and habitat loss. Additionally they are typically owned by the owner of the property that it powers. No big Corporation or government needed.
He is delusional if he thinks hydro has enough energy to power jack shit. It's always going to be small beans.
i'll take coal or hydro over nuclear any day
Coal causes cancer and mining it is an environmental catastrophe worse than Chernobyl.
Константин Захариев Give it a few more decades of R&D. We have safe and practical technologies we can start using today.
yTube BlowsBigBalls The first positive energy reaction was accomplished this year. Only a little while now. Nuclear is better than coal
yTube BlowsBigBalls what about the radio active waste that stuff will stay like that for life
jonathan oxlade if they switched to liquid salt reactors there would be no radio active waste left to be a problem (they use over 90% of the fuel and what is left is safe and can be used for other things (ie magnets in wind turbines and for the production of solar panels).
the problem with solid fuel reactors (current reactors) is they only use 10% of the usable fuel and that is why it is radio active.
the best part of lsr's which is the same reason why they are not used is that you can not make A-bombs from the waste due to it not being radio active
nuclear power is the best way, end of story.
Harry 8642 nah hydro is better
jobama 64 unfortunately not enough water to do so, and when or if fusion is figured out, nuclear/fusion will be the way.
You watch much tv a high school kid did it in his garage and already was given a full scholarship to 4 years of college. His parents must have been clueless as to what he was doing.
Because all the energy used to mine, refine, and store nuclear is better?
How much do you think it will cost to secure the nuclear waste for 500,000 years? And that's only it's half life
