Love these simple reusable concepts! You could make a usefully efficient primitive wind powered heater with no electricity at all. Or use it to charge a thermal battery. You could even use a water wheel in a river/stream to boil or distill the water for consumption. Very versatile. Thanks as always!
Thanks to watching some of your videos for a while, I have come up with an idea for a safe tent heater. The body of the heater would be very similar to how propane bucket forges are made. A metal container lined with that kaowool stuff, an input vent near the bottom, an output vent on an elbow out of the lid (to aim the hot air), and a small stand in the center for the heat battery. The heat battery would be a 5 pound steel mass with a loop built into it to allow it to be picked up by a metal hook and is small enough to fit into the stove. The idea is that you use a rocket stove or campfire to heat the battery, place the battery into the stove, move the stove into the tent, and then control the output a little bit by limiting the air that can go in from the bottom. Having the stove mounted to a small dolly, so it sits flat but can be easily shifted onto wheels to move it, would make it safer when moving it while the battery inside is hot.
One day when doing some service on my diesel Jeep I discovered an odd device in the serpentine belt loop. It had a clutch and seemed to cycle on and off. Later I discovered that the device was called a viscous heater. Odd I thought, why would the Jeep need such a device. It turns out that the diesel engine doesn't heat up the coolant fluid quickly enough to satisfy some regulation regarding the time allowed to defrost the windshield in cold weather. There may be some kind of heat exchanger in it to transfer friction heat into the engine coolant circuit, but Jeep might just whip around the engine coolant directly. Of course, once the engine coolant is hot enough, a control circuit will disengage the clutch therefore maximizing fuel economy while meeting the windshield frost clearing regulation. Ingenous!
This one is wonderful! My friend asked me a couple years ago about this subject and i could just vaguely tell him about it. Now i could send him your clip and Frenette's patent link 😁 Thank you kindly! Sharing knowledge makes us all grow :)
I like this friction heater in connection with a metal bucket sand battery, a shielded from the heat universal planetary gear (video 2009), a hand crank, and a thermoelectric heat fan.
Lovely had looked at the fernette heater many years back on TH-cam. Using your gear ratio mechanism and a small motor to run it via a solar Bank ie car battery comes to mind. Thankyou for upload Robert and taking us down memory lane❤
Why use a motor for friction heat? If you have solar/battery buffer to drive the motor you can direct heat water/sand via resistors. Whats the motor for ? Missed it in the text maybe.
Cool inventions Rob love the old mechanicals. Magnets on Aluminium eddy currents. And also Yamaha has just released there new (Teg's) thermo electric generator's, for hybrid ev's. Very interesting but not sure on prices yet.
There is also a induction heater using copper coils and rotating magnets. That probably could be pedal powered, with the proper spacing and gearing. Im sorry, copper tubing, not coils.
I'm thinking how long I'm following this channel , because , I actually remembering seeing that video. Also remembering some videos made in Rob's kitchen...It's sad - I'm getting old...
Mentioned this before, but . . . the Frenette heater they used to show diagrams of in Popular Mechanics, et al, was a hollow drum in a slightly larger hollow drum (they recommended starting with two identical ones, cutting a narrow vertical strip out of one and welding it back together) with a fan mounted in the inner drum. When you spun the inner drum, it forced air through to move the heat out. Some duct and a wind turbine, and you'd have free forced hot air when the wind blew.
Simple added cost and complexity is always more efficient. Cost efficiency and inertia is why we have the system we have today. The beauty of that statement is that it will always be true until someone wastes time and energy doing something different or until a con becomes a pro.
They are only when you directly transfer the rotation energy (windmill) into the heat via a shaft. No electricity. Then you pump that heat if its water also via mechanical driven pump to where you need it, and store the heat hopefully in an insulated reservoir. Or heat up stones/sand etc to bring somewhere. The problem is the friction leads to abrasion/dust, even under water. If you attach an electric generator they have local losses as heat, a brushless generator only has friction in bearings that dont wear down if done right, and "friction" in wire resistance. So if i had the option for electric stuff/wiring i'd always go that route, even if it means loosing 15% at the generator. Because its also easy to switch off. Addit: a water pump / waterbrake (rowing trainer) might actually be abrasion free, because its the water getting warm through movement/inner friction, not grinding away the pump.
What I wonder about is if all that friction would not quickly degrade the materials used to apply the friction to. If used long term would you not need to replace parts rather quickly?
Hi A bit off topic but some 20 or more years ago I watched a technical programme not to dissimilar to equinox or tomorrow's world and the subject was a water heater that was motor driven, driving a rotor in a stator with carefully designed divets in the rotor and stator, on running the device at a certain speed with water running through it it was claimed to heat the water at close to 100% efficiency, I have trawled the interweb and can find nothing just wandering if you might have seen this or are interested
Search for the story of the Griggs hydrosonic pump. Rumoured to be 115% efficient, the extra energy coming from the collapse of the cavitation bubbles. The design was sold to an oil company because it also turned out that the device was particulary good at mixing liguids and gasses, something that oil companies do apparently. Pretty soon afterwards it disappeared from view (what a surprise). At some point in the distant past,a Russian company was producing a cavitation heater that utilised microwave generators. Very efficient and no moving parts. Try finding them, good luck.
It is very amazing to me how you seem to be looking down the same rabbit holes as I have been, Just this morning I was thinking can a solution produce heat by friction, absolutely amazing as usual M8.
I was also thinking using the fernette heater with a permanent neodymium magnets stuck on an rotor with the inner cylinder and a brass cylinder located internally stationary thus making use of the heat form then which would dissipate to the oil and its surroundings
P.S. The friction heater, sand battery, gearing combo: The gearing (video 2009) is removal to be used on all your other friction heater sand batteries.
Using something with a low boiling temperature. To build a micro steam turbine, to generate power from the brake heat, also the exhaust heat, the coolant could be used as a pre heater. In a hybrid car, the engine coolant could have it producing a small amount of power, go up s hill. The exhaust heats up the steam engine takes off doubling the power. Then down hill the brakes heat up the turbine takes off again charging the battery. The engine coolant generating possibly 10% of the power then the extra heat pushed that to 60-70% it could work, especially for stationary generators, also incorporate a DC generators , I was thinking of a turbo that generates power instead of boost! A gear reduction drops 60k+RPM to 15-25k rpm. Generate electricity. It could be possibly 2kw easily I believe a 6-7litre could do 10 kw from the exhaust. Only loosing a unnoticed amount of power.
On second thought, I think I'll go the added expense of a heating element sand battery system. I wonder if I can generate enough hand crank power. Perhaps videos 2034 and 1752 will help me.
What is the unit for acceration of heat? If you're converting energy from wind to electric to resistive heating vs wind to dynamic friction to heat than it follows that both systems can have a variable" brake" to adjust the heat. So you want energy acceleration because some one out there wants to use calculus tools and a vector field of how fast that heat is getting there to compare electric vs friction.
There is a company that uses a similar principal for a water heater. There are videos floating about of their "water hammer". I will see if I can find one to share in the comments for those viewers who would rather not be troubled with searching for themselves.
What Robert is demonstrating is a laminar flow friction heater. The water hammer is a modified version by drilling holes in a solid rotor at specific diameter, depth and angles that creates increased friction turbulence. I looked for it by the names water hammer heater, Ausie water hammer heater and other labels and came up empty in my search queries a few weeks back. It's been in my bucket list to experiment with since 2015. The water hammer employed a 1/3 horsepower 3,200 RPM electric motor as I recall. It was touted as an over-unity device as are other devices like some microwave magnetrons and magnetic amplifiers. So far in my journey I've not experienced free energy however have been surprised that the "Q" factor can be much higher than indoctrination of my formal education dictated. It's like a sailboat being propelled by the wind. When the wind quits a sailor needs another form of propulsion to keep moving, paddles, pulse, jets, propellers, impellers, steam, motors, engines, rocking the boat, tow or even nuclear. Harnessing a horse isn't free because someone thought making hemp illegal was a good idea because idiots started smoking rope. The surgeon general warned that marijuana use during pregnancy can be dangerous to a developing fetus, and that marijuana use during adolescence is associated with changes in areas of the brain involved in attention, memory, decision-making and motivation.
A couple of decades ago or so, there was a man who was selling a water heater, much the same principle, but the rotating cylinder had its surface drilled with many shallow holes. He claimed that the size of the holes was critical in achieving maximum heat out put. The energy out in the form of heat was greater than that used to turn the cylinder. Some pundits said it was impossible, but the measurements confirmed it. One of his customers also confirmed that his heating bill had reduced significantly since installing one. .
You could be correct. That sounds logical. Too long ago, and names don't stick for me. There must have been an ''ignorance factor'' involved when calculating the output. Something must have been happening that the pundits were not aware of. @@Moogus
In the mid-1970s one of my engineering professors built a proof of concept device that heated water mechanically by applying shear forces to very thin layers of water. Results were underwhelming!
Robert, I have sent you 2 emails about using Hemp & graphene PLA (they may have went to spam). Are you or your company available for consulting or making a Data sheet ?
What if you make a type static generator... A wheel with hair at its edge and an outer ring that harnesses the static that gets conducted when the flywheel rotates and the hair make contact with the silicon and air in a simple semi-conductor fasion?
I remember a Facebook article about this black American inventor inventor Charles S.L. Baker who is said to have invented the first frictional heater. Maybe you could do a video about it.
The short answer is that it depends on whether or not you're salvaging the heat from the exhaust of your generator. If you are, then both systems are approximately 100% efficient, as thermal energy is the final product of all energy transformations. If you're not salvaging the heat from the exhaust, then wind>thermal wins by a huge margin of 70% to 95%, depending on whether you mean "generator" as fuel>mechanical energy via an engine>thermal energy fia friction, or as fuel>mechanical via engine>electrical via generator head>mechanical via motor>thermal via friction, with the latter having rather abysmal whole system efficiency.
Wrong question, do you want to pay for the extra efficiency. Magnets, wires, and carbon resistor cloths cost money. Unless you're asking how much heat per RPM per second, which if I convert units in my head the minutes in RPM should cancel the seconds which should give us heat per angular time. My question is what unit is that? Polar watts, polar joules?
@@ThunderboltWisdom not necessarily, because in that system, the water undergoes a phase change to steam and is directed to a turbine. What I'm asking is can you have a system where you heat the working fluid and it spins a "turbine" without really going anywhere?
@@samuelvoss9381 Ah, you mean the upward movement of the heat driving a centrally placed turbine? Is that right? I can't think of any other way heating a liquid could enact a force on turbine blades.
I've always believed friction is the best way to heat a bedroom. 😂
If there's enough friction to heat up the room, you're doing it wrong.
If repeated opposing forces alternate their overcoming of inertia of the vehicular residence, don't impact the entrance with your carpal phalanges.
Don’t you get a smell of burning rubber? Phil.

Thank you RMS. friction = heat = energy = recharging you phone. lol DVD:)
If electrical resistance is close to 100% efficient, why would friction heaters be superior for use with portable heaters?

Try rigging up the friction heater to the linear generator. (Air loom) 👍
