Is actually 'from thick air' given that is is compressed to over 1 atm.

@BenskiBoi

Ай бұрын

Yes because energy can’t be created or destroyed only transfer

The turbine would probably work better without the spacers between them, so it's not as easy for the air to escape through the side (probably not a big difference tho) And the piston engine would be more torquey and smooth with a second cylinder 90° out of phase (so there would be no deadzones without a power stroke)

He'd need to build a core with control rods, then build a water heater that uses the heat from the core to boil water into steam and make a turbine spin. It would work but radiation, cost and legal troubles are things to consider.

Great idea and execution! One idea for improvement: Remove the spacers between those turbine wheels. You are losing airflow there that you could use more efficiently if the gap between the turbine wheels was a small as possible.

I would add a gearbox to make it able to spin faster, as the rotor acts like a flywheel. I would also make it water based as water is heavier and cannot be compressed, making it unable to lose power that way. But overall, nice work!

Would like to see your 3 phase generator power a 3 phase brushless motor. Don’t forget to add load so your inrush current doesn’t damage your motor. Edit: I just discovered your channel. Going back over your other videos, I came across your levitating fan. This might be an excellent candidate for a 3 phase motor. It would eliminate the need for the reed switch altogether. Just in case you don’t want to do the conversion, I posted another suggestion there.

Another excellent idea, thanks for all your suggestions today! That's true, treating the fan as a traditional brushless motor is totally doable.

ah, an example of peak kettle harnessing technology, but applied to wind rather than steam

Use a MPPT chip to gather as much power as you can! You can charge up a LiIon cell, and probably expand your lighting time at least a bit. The passive AC to DC is lossy, and you waste ennergy by not using all the voltage and current when available. An MPPT chip will help you with that = ) Also, the flying wheel was like a mechanical capacitor, it would improve stability a bit too (even is your last design is "heavy", so it probably don't need it). So, yeah, nice video, thank you!

Its kinda possible to create a generator from spinning a bike wheel thing, like just attach a big gearbox to it (obviously not a lego one) and connect it to these magnets in a bigger circumference and a bit more of the wire, and you have a big voltage generator!

When the magnet thing spins it sounds like if kirby was trying to consume something 😂😂😂

how do you make your coil? is there any special way you wrap it in to a circle? and one more question. what wire do you use

@JamiesBrickJams

2 ай бұрын

Those coils I actually just wrap around some Lego. The middle is a small technic smooth bushing, and then I often sandwich it between a couple of Lego wheels or liftarms. Then you just wrap a bunch of turns! At the end secure it by wrapping a bit of wire around it. I believe these coils were made with 30 gauge copper wire

8:33 altho there were 3 coils, not 1. But anyways the fact that you can make energy just with bricks and air is insane

The video is nice 👌 My question is , how do you achieve the required air velocity at the nozzles out of “ thin air “ ? I assume this is nothing but a mini windmill ! But how to convert thin air into compressed air of pressure & volume ? 0:07

@JamiesBrickJams

5 ай бұрын

I guess a turbine is technically a kind of windmill with extra steps. Not sure I entirely understand your question, but the air nozzle is just supplying compressed air (at high speed) from those bottles. And the bottles were supplied air by the compressor. So as the bottles release air and return to atmospheric pressure, that high speed air turns the turbine blades, which then go through a gear reduction to turn the rotor. The term 'out of thin air' is just a fun play on words 😉

Cool

When u will find now a little Compressor, wich use low power, which can produce "air" witch is much enough to blow the turbins.... do u will have than a perpetum mobile??? or endless energy and energy left - p.e for light

Sry i might be stupid but HOW does the air transfer from the bottles to the Valve U put something on the bottles to press the air out ? Or am i missing something

@JamiesBrickJams

Ай бұрын

So the bottles have a pipe going into it, and a 3 way valve connected to that pipe. A compressor then pumps air into the bottle, and the valve is then switched to the middle position, sealing in the compressed air. Then when you want to reject the air, you simply open the valve again. It's just a standard Lego pneumatic valve!

Yup! Any time an electrical load is placed on a generator, you can feel the resistance against the generator input. So for example, if you crank a generator, it'll move easily with no load.

Add an electrical load, and the engine will take the strain. Sometimes even enough to stall the engine. Kind of like starting a car in 5th gear
