I’ve been thinking about feeding chickens with the compost pile, that’s why I got the chickens, and have a pretty compact layout that could be used in a small space. Instead of a tractor, as in Geoff Lawton’s video, it’d be a fixed thing, where the food scraps go in on one side and compost comes out the other.
The drawing shows the food coming in to the first area, where the compost pile is first made, and the chickens could roost above it, manuring it through the first week when they sleep. After a week it’d go to the next area, then the next, then the next, and then out of the enclosure.
So the procedure would be: get out the 4-week compost, move the 3-week one there, move the 2-week one, then the 1-week one, then build a new pile.
The whole thing could be enclosed properly to protect the chickens, but the divisions inside would only be about half a meter tall. Those divisions would keep the piles more or less separated, but the chickens would easily move between them.
Each division could be around 2×2 meters, so the whole thing would be 4×4 meters, plus access space on one side. It could be made smaller too, but this sounds decent enough for many, and good enough to start a conversation about it here.
Last time I posted about hydropower, and now I wanted to touch on one less obvious application for it.
Normally one thinks about streams in the woods, or some such usual place for these micro-hydroelectric things, but this can even be used in cities.
Normally, only wind and solar are thought of when talking about natural power generation in cities. Yeah, there are also the plants that process waste and get methanol from trash, but those are not something most people can just purchase in a store and install in their home.
Most buildings have a pipe to run rain water from the roof down to the street or a drain. This pipe has a huge drop, and it’s a great place to put one of these turbines to generate some power. The higher the building, the more turbines you can fit. Since the turbine will slow the water down, you’d need to space them for the water to pick up enough speed again.
Yeah, it doesn’t rain all the time. Sun comes mostly daily, same with wind, but rain only has certain seasons. Still, it’s quite a lot of power that could be gotten from it, and would help assist with cooling/heating consumption, depending on the need.
It’s an alternative worth exploring, and a turbine as small as the one in the other post certainly makes it easier.
Hydro power is one of my favorites, together with wind. And I like it micro, as with most implementations, because they’re so much cheaper and also easier to accomplish in more places. I’m a big advocate of descentralized solutions, and this is one example.
I’ve found several good solutions for it that I liked, but I have some comments to make on the one I found today called HydroCoil.
The concept is nice, and seems to be way more efficient than traditional approches, but I don’t think it’s really new. This bears a huge resemblance with Viktor Schauberger’s designs, like the water jet turbine’s.
Schauberger’s jet turbine, too, was highly efficient compared to traditional designs, even as heavy as it must have been, built of heavy metal instead of a lighter material as is possible today.
You can see in the HydroCoil’s design, that they followed the vortex’s flow for the helix. This is nice because as it takes the power of the flow, the increasing angle of the vortex takes more from what’s left, while it changes its vector almost 90 degrees from entry to exit.
Part of the power they get from it when the water flows is the push the water effects on the blade, as in a regular turbine, but there’s also the propulsion at the exit, where the vector is almost perpendicular to the original flow, causing a propulsion that assists turning the turbine.
That is pretty similar to what happens in the Schauberger turbine shown above, in the screw part of it. The first part in his design, the tube, was to increase the flow’s speed first and get more power, with a ribbed cone, like a funnel but with a twist: vortex. So he first imploded the flow and then exploded it.
If the HydroPower design had the vortex in the input, it’d increase its output even more. They could probably take other ideas from Schauberger to improve their design. Schauberger’s works are something really nice to read about and research.
Another thing they could do to improve the output is lower the magnetic resistance the generator creates when spun. This back electromagnetic force acts as a brake on the generator, reducing its efficiency drastically. This is well explained by Peter Lindemann in his Electric Motor Secrets video.
I like that there are companies working on these solutions and putting products out that’ll help people use them.
I’ve researched how to improve fuel efficiency for some years now. I haven’t had a vehicle of my own until just a few weeks ago, which made me look into this subject one more time and I found a couple of new mods that I had not seen before. They are the discoveries of Somender Singh and Ron Hatton (a.k.a. Gadgetman).
Somender’s groove goes in the cylinder’s head and helps reach the gas in the squish zone, while Ron’s groove goes in the fuel/air delivery system and helps better vaporize and mix the gas in the combustion chamber. The way they work is different from each other, but I find it interesting that they both require just grooves to be created in the metal, which is why I’m posting about them together.
Somender’s observation was that in the squish zone of the combustion chamber, meant to squish the gasses into the center, there was an incomplete combustion. He also concluded that it added resistance to the piston. His solution was to add one or more grooves that would help channel the gas from this zone towards the sparkplug on compression, and then allow the combustion to reach that zone. The results from making this simple modification are very impressive from photographic documentation.
He isn’t charging for this, he’s open-sourced it and the groove isn’t tricky to make at all, the instructions are simple and watching/reading the stuff below should allow you to understand well enough the technique.
Ron, on the other hand, tried to improve the mix of the air with the gas, and added his groove to the fuel/air delivery system. This is the part that lets more or less air into the engine carrying fuel with it, it’s what you control with your gas pedal, which should probably be named air pedal. He explains that these grooves create a toroidal (donut shaped) flow and improves the amplitude of the air pressure. This more compressed air/fuel mixture, when entering the combustion chamber through the intake, expands abruptly improving the volatilization of the fuel. Gas doesn’t burn well as a liquid, even as a small dropplets, compared to it in a gaseous state, which is when it’s mixable with the oxygen gas to combust. Also, fuel vapor is several times less dense than liquid fuel, which means you require less gasoline. All this contributes to the fuel efficiency.
This groove is more tricky, though. The shape has to be right to cause these effects and getting it so takes a bit more knowledge about it. Ron has a certification program to train those who want to learn it, which you can read more about in his website. You can have your car modified by him or someone in his network if you don’t learn it yourself.
Both modifications require the timing of the engine to be adjusted for the improved conditions. Both help keep the temperature down as well, oil lasts longer. Both improve combustion meaning there’ll be less wasted fuel in the exhaust, dirtying the engine and polluting the environment, and wasting your money.
In essense you use less gas, get more power, engine will last longer: pretty efficient if you ask me.
I’m planning to add both to my engine and will report back. I haven’t seen anybody mention using both together yet, so I’ll add them separately to see what difference each makes. I’m hoping to see great results with both.
