Besides the efficiency of the collecting device, one would think that these students would know how to look up calculating the available energy in the water and how it is related to the drop in height and the flow/volume. For starting students this is a very good way to imprint the importance of understanding the basics, doing research into other projects (many available on UA-cam), and good modeling. I would have given the team with that long tube from the building site the best chance of succeeding, as that would give them the opportunity to create the biggest water pressure/head. I am no engineer myself but I feel projects like these give the students an understanding of why all the other stuff they are required to learn is important. Great video
Really enjoyable to see all of their efforts! I'm slightly surprised that with all the different projects nobody is trying to use a vortex generator, I'd love to see students exploring that concept and I think it would be kind of ideal for small scale projects like these
Good video! I thought of my own design recently, for use in Ukraine ... A disc + spindle, curved blades attached within, but leaving a circular gap in the centre. The whole thing encased, with an entrance hole for the air/water stream, plus an exit one almost directly opposite. The fluid hits a blade, causing it to turn. The flow then continues along the blade, crosses the central gap and then proceeds to push one of the returning blades, in the same direction of rotation. Finally the fluid leaves via the exit hole. PS The spindle itself could benefit from being a spiral, with gaps of it's own. PPS I've bought some bits to make a test rig, but still TBD!
Special thanks to everyone involved in this project and made it happen. This was a real treat to see. In my humble opinion, I feel 3D printers and laser cutters should be prohibited for this challenge. Vertical wheels with buckets should also be prohibited, or at least limited in how many teams can use them. I only say this because I think it would encourage more outside of the box thinking and resourcefulness of the students/participants. Surprised none of the teams using water bottles thought to have a multitude of bottle caps with different sized holes drilled into them to adjust water pressure/flow. Looks like a fun and interesting project. Too bad this was far too short of a video to truly get truly invested in any of the designs, and with the exception of the Archimedes screw, most of the designs weren't distinctive enough to feel invested in. Be nice to hear more about what was allowed/disallowed for use and more about this semi-competitive project or competition. Not sure why disclosing the power output generated by each design would discourage current or future students, especially since each of the groups remained anonymous. In my opinion the metric of being able to power a light bulb or not seems more embarrassing than getting the clinical raw numbers of voltage and amperage. Now all the designs are judged by a pass/fail binary. Not being able to get some unknown bulb type to light up doesn't tell any of us spectators anything. Seems antithetical for a university or school to hide information that others may be able to appreciate and/or learn from. The light bulbs not turning on could be anything from bad connections to faulty bulbs, so it would have been nice to see each design spun manually and see the bulbs light up before being placed in the water so we spectators can see there's no faults in the wiring, generators, or bulbs. Still enjoyable to see projects like this take place. Thanks again.
was a waterwheel / slow bucket elevator type with gearing not allowed? E=mgh, a tall, large chain bucket elevator fed from a large pipe high up the river would be optimal, no?
Muito ruim esses videos de trás para frente das turbinas. Muito ruim os projetos, muito sem critério os testes, em anos a ideia boa deles não evoluiu a ponto de melhorar dar mais infraestrutura aos alunos. Então a cada ano os projetos são até piores ao invés de ter um salto evolutivo. Orçamento limita, mas a falta de história entre os diferentes anos, não cria o paradigma necessário para uma competição desse tipo ganhar sua característica ímpar.
The ultimate reality check! Build it and try it :)
Good luck to all the future engineers.

never seen a vid like this - incredibly interesting and well made ryan! :D
How many watts did your efforts back in the day produce ? What are these students studying ? Thank you .

Maybe the attempts to make a jet of water just reduced flow and speed.
Also directly driving the generator seems like a bad choice.
"found" in a construction yard...

The bot comments are wild xD
I watched this video at work and now my coworkers are laughing too. A great way to lift the mood in the office😻
This video is the best way to forget all your problems and just laugh. I recommend it to everyone🍓
When you realize that cats can do everything better than you. Even be funny😚
