Off Grid Micro Hydro X-STREAM Engine Upgrade

We upgrade the Off grid Micro Hydro EMPIRE with an X-Stream Engine from Energy Systems and Design. We magically mount the machine in the river, connect it to the penstock, and wire it up. Then the tricky part; optimizing the nozzle size, rotor height (magnets) and MPPT settings to get the most power.

do you really need to ''subdue'' the river?... can't you just let it be and use a simple paddle wheel? [make one by yourself! ] that will last for decades?...

[@cooltrkin]

It seams to me a paddle wheel with sprockets and pollies and generators. Would be easier.

[@kennethkeen1234]

@@user-McGiver Yes, it seems like they (Jeff is to blame ;-) you can take it big boy) are getting to playing like "government employees"*. Perhaps it is the money being made available - or fame for the client..... Drilling holes in rocks that have been there for 60,000 years or more, from what I see, is noting short of graffitti. Or vandalism!! Why not a long bar from side to side of the valley secured in a mobile concrete base (wheels can be inserted so that it can be rolled out of position)with a wheel on it, and the whole rig secured from a high tree above? It won't last a heavy storm as it is. I've just had 3 ton trees sweep past my window this last week, and another 7m oak stuck right now needing to be cut up and removed - perhaps only 2 tons, but if you get that sort of stuff comind down, you'll be properly tested - I know the catchment area in question is much smaller than my area, I'm not half way up a mountain, and those levels of water flow are not likely to arise, but none the less, construct something that can be protected or removed in seriously bad times, because they are coming, or didn't you get the message? * unproductive

[@chrisdaniel1339]

Pebbles and rocks in the crossflow turbine is not the fault of the turbine manufacture it is because you guys did not use or make an appropriate intake with a coanda screen or sediment/pebbles settling tank before entering the penstock. If you do not screen your intake water with the new turbine the sand and pebbles are going to wet sandblast the plastic nozzles and the stainless steel Turgo wheel.

[@Natreely747]

The gravel and sand will still cause problems in wearing the turbine runner and nozzles quickly, if you don't improve the intake. Ideally, a coanda effect screen intake designed with an accelerator plate leading onto the screen, making sure the water is doing at least 1m/s across the screen, keeps any solids suspended higher in the flow and only clean water is sliced through the screen. When designed well, with enough bypass flow, coanda screens should be self-cleaning. While the wedge-wire in the screen is not cheap, the overall cost can be reduced by making the screen housing yourself. Never hear anyone complaining about the cost after they are installed, as they are so low maintenance.

[@JohnSmith-pl2bk]

Build a flow over dam and take the water into the penstock at the half way point between the surface and the bottom... the gravels all fall to the bottom of the pond... the sticks and leaves all float over the top of the dam.

[@portnuefflyer]

I removed my coanda screen intake, after 18 years of use, as it was a always a bit of a hassle to keep it "happy" with precisely the right amount of flow, as I don't have the luxury of a proper coffer dam or accelerator (?) plate, it's just positioned directly under a culvert! It also had moss or some kind of fungus that had to be sandblasted off every few weeks during the summer, if not the delivered flow would drop off. I replaced it with a simple steel trough, 4' long x 12" wide, with stainless 1/4" mesh on top, it's on a slight downhill incline. It's worked great for 2 months now, full delivery 24/7, total cost about $100.00. 147' of head, 3" line, 33 amps @ 26 VDC, grid tied, via an Outback 3500 watt inverter, with an additional 1500 watts of solar to the same inverter. I was off grid for 28 years, due to no powerlines to my old place, now, on my new 70 acres, I am grid tied, with a simple net metering system, so I don't waste a single watt with fully charged batteries! I get every watt back I produce, no matter how long ago. Being off grid is great, if you HAVE TO BE.

[@heathhill7802]

Lookin good , never underestimate a few watts thats consistent. Time flies and battery's are easily over charged . 5 6 7 hundred watts consistent is way better than 2 to 3 k of solar in a day plus draining batteries every night , I would like to point out that keeping the 3 phase run up to the house is more efficient. Easily rectified before the charge controller. Not knocking what you got , Iv done the same . It works , you know the numbers you adjust . Theres living and living well Awesome setup, and cool video.

[@AbdulWahab-on8om]

I don't understand all that mechanical and electrical engineering stuff but i watched the whole video with great interest.

[@hrford]

The difference between the 560W calculated and 460W displayed might be due to two effects: 1) If the DC is noisy, then the bandwidth of the measuring device or if the device is measuring average or true RMS (Even of the DC amount) 2) you might have some phase difference between the current and voltage devices, even thoug it's DC the ripple might be causing this. You'd need a proper true RMS power meter to calibrate the MPPT converter's display. If the MPPT likes to O/C the input thinking it's a solar, then you'd need to dump power for a hydro input to keep the turbine loaded, you have the power dumping relays, so you could setup the MPPT to target a voltage above the load shedding devices. All pretty interesting :)

[@66bigbuds]

[@sevilnatas]

I have been thinking about sand batteries lately. For systems like hydro, wind and solar, when they have maxed out their battery charge, they need to expel their power somewhere, which is often in big resistors, that turns power into heat. That is perfect for a sand battery, which is a very large mass of sand, that uses a resistive heater, it turn power into heat, that a sand battery is very good at taking in and hold over long periods of time. Seems like if you dig out a really big hole, dropped a large diameter culver pipe to the bottom, maybe 5, 8 or even 10 foot in diameter, then filled up around it with the dirt from the hole and fill it with whatever special sand is required, (obviously including whatever electronics are required, which I understand are pretty simple), you got yourself a good long term store of extra power or heat. Whatever is most valuable to you in the moment.

Awesome ! I loved seeing other peoples hydro setup.everyone’s is different. Mine makes around 1.5 peak in the winter. 8” pvc penstock with two turbines. GPM varies but winter it’s roughly 500+. With 55 ft of head. Works great.

[@CajonLiving]

I would think sizing the nozzles all the same then use the valves to tune for peak power would be the way to go. This way you could compensate for the hose connection header and different hose lengths / bends, putting the same flow pressure at each nozzle. Then you could eliminate any cavitation, which would increase the turbine RPM giving more power. I must warn you that I'm a retired engineer, so as an engineer, I'm sure we could improve on the design and make it where no one could afford one. I Like your videos; they make realize how much of life I missed out on living a corporate life.

[@runnerkid100]

Great machines! Don’t get hung up on free-wheeling with those specs. At 15psi, the nozzle velocity is simply not fast enough to cause high voltage damage. You don’t want constant free-wheeling because of the extra duty on the bearings, but nothing is going to burn up. My system is nearly identical (31’ head, 4x 7/8” nozzles over winter. 600+ watts.)

40 years ago, we dug a trench from the middle of the stream behind my dad's place in White Pass, WA two feet deep in the bottom of an existing hole above bedrock and paralleling the flow to a penstock with a 50 foot elevation difference, inlaying a 3" PVC pipe to run a turbine. It's worked flawlessly year round ever since. Turbine was an under-shot Pelton wheel. Inlet was an inverted stainless steel drum with 1/16" holes punched in its cylindrical sides to let in maximum flow and minimum debris.

hydropower is perfect if you can use it the problem is that you need a decent drop on your property to create the necessary head pressure to operate any turbine, and even more if you are using a high-head low-flow design(which is often the more compact and powerful, though harder to keep clean, wonder if the first video that brought me to your channel should have included a centrifugal separator partway down instead of that screen in the intake sump...) it might be possible if you can set up a ram pump to get the required head with minimal flow, though the number of them required would be problematic and given mountianous water you could even easily collect some for use in your own domestic water(just make sure to have an adequate filter system(probably an intake UVC then sediment filter(oversize the filter to ~5x what domestic sediment ones would be for longevity, and maybe add in a spin down just before to help) then a carbon(might be part of your sediment if you get dual-mode carbon block filters) then RO then DI(you might bypass the DI or even the RO for non-consumption flow(like showers and toilets)(or just use the waste flow for that)) the fact that you have a clear stream with large flow and drops will be perfect for most water and power needs(plus you can take all that biomass into a bioreactor and use spare electricity to purify and crack the gasses into sellable pure butane/propane to get extra cash

I did a little calculation and it appears that that controller is reading AC Watts when you're feeding it DC power... perhaps the settings in the controller power monitoring circuit is the reason for this. DC current delivers √2 more power than RMS AC current over the same period of time.

[@garfieldwood8315]

If the controller is using the peak ac voltage as its bases for calculating power and using 7071 * the peak voltage as as is using AC RMS power calculations then that would explain the discrepancy and the output power readings
