Grid Down Electromechanical Voltage Conversion & High Tech Survival! How to charge 48v from 12v

[@MrBasilkey]

I still have a box fan that I put an auto radiator fan motor in it. 6 amp pull. I think it would work ok with a 12-volt solar panel. Never did try that yet. I have around 1500 watts at 12-volt. I did make a solar ceiling fan that we used for lots of years. Wife wants me to put it back up. I used a 36-volt DC Ameteck motor. Worked great. I used an electric heater element for speed control back then. I now use the cheap dc to dc controllers form China. You have some great videos. I just found your site. I will be looking at a lot more. Thanks.

[@solarpoweredge]

@MrBasilkey Hi, glad you found this site... nice fan mods.... yeah I am sure it would run on a solar panel, even a 50w panel would probably get some good cooling

[@wpgenlighten4truth2]

This is an AWESOME VIDEO, I Always Wondered if this would Work ...Thank You for Thinking Outside the Box ...THIS IS GREAT ...!

[@solarpoweredge]

@wpgenlighten4truth2 I am grateful someone can see and understand the point of this video :) Thanks for being open minded, and for your kind feedback and support. I tell you yt has been so hard a place I cringe to post my videos any more. You wouldn't believe the comments I get lately. I hope these videos help people... right now spinning motors might seem wasteful, but hey if the grid goes down, everyone just might be sorting through the junkyard trying to find a motor to charge up their ebike from a 20w solar panel :D it could happen! least of all the knowledge is valuable :D

Ahhhh this video takes me back to the 90's here in Melbourne when we had a fire at the natural gas works and since most of the houses need gas to run the stove, heating and water boiler, should have seen the mad rush to get out and purchase something to cook and boil water with that didn't run on natural gas.... I still remember going into apocalyptic survival mode.... I took an old oil drum, cut it open at the top and put some breather holes in the bottom, then I took apart an old box AC unit that I brought home ages ago for reasons I couldn't remember, I took out the larger radiator and put it on top of the oil drum which now has firewood in it, with some Teflon tape I was able to get the garden hoses to fit into the radiator, the other side of the garage hose went to a tap which will supply the radiator over the fire with cold water and then send it to the boiler and into the overpressure release pipe which was easier to open the tap on to let the hot water to come in.... All I had to do then was turn on a hot water tap inside the house to complete the system and in a short time I had a boiler full of hot water for showering! While others were having a bath like it's mediaeval times in England, I was having normal showers like nothing was wrong! I know a lot of people who will pick up a nut or screw around their property and toss it in the bin, I'm not one of those people! I will admit that I'm a hoarder.... But I will never throw something out only to need exactly that a month later and then go to someone who hoards stuff expecting them to provide me with whatever they were hoarding! If I'm going to through out everything, I should always remember where all the shops are and be prepared to pay.....

[@solarpoweredge]

@PeterMilanovski What a machine... that is exactly the kind of engineering I like and respect. Getting the job done! My hot shower is literally an old cat litter bucket with HWH element, and /or a cheap insulated cooler with heating element if more is needed. Hot showers are critical to boost morale during bad scenarios :) PS I will admit, I am a hoarder. Can't even throw away plastic cutoffs, cardboard boxes, bits of wire insulation, bottles, it's terrible. On the other hand, "waste not, want not".

[@PeterMilanovski]

@@solarpoweredge I think that a good way to heat water is getting a square aluminium pipe, seal up the ends, tap some threads and install some pipe connections at either end, get some TO220 diodes and line the pipe with them, you can probably solder them? Not sure if their metal tabs are connected to one of the pins? Or..... You can use Peltier devices which are a heat pump after all!. Something to use as a thermostat and a small water pump to circulate the water in a tank..... Or possibly go tank less and just use more aluminium pipe, each Peltier device doesn't need to run at full power as the water should be getting progressively hotter the further it gets...... You then can control the voltage to get the water at the right temperature..... Lots of ways to go about it....

[@solarpoweredge]

@PeterMilanovski Found some metal pipe that's 2 inch square, it just might get turned into something. Tons of ideas here :D

[@PeterMilanovski]

@@solarpoweredge there you go! I have some aluminium 2 inch square tube left over from the roof installation of solar panels that I have been planning on getting the ends sealed off but I don't have an aluminium welder, recently I was introduced to someone who can help me with that! My first idea was to put Peltiers on it to generate some current form waste heat, then use that current possibly via a DC to DC converter to drive other Peltier devices to actively cool the (either) other end of the square aluminium pipe or use a separate pipe.... Basically the idea is to cool down the waste heat water using the heat to cool it with.... Totally silent due to not needing to use a fan! Using a Peltier device or devices to actively cool, if enough can be used should theoretically get the return water to be cooler than what can be achieved by a fan and radiator.... The only issue I can foresee is the size of it! It could be designed to sit close to a wall and run up the wall, a shroud around it would use the convection cooling system to avoid using any fans..... I'm thinking that this would be a good way to cool a Peltier device fridge freezer, the complete system being solid state, no moving parts and very quiet!

[@solarpoweredge]

@PeterMilanovski I like this idea very much! I suspect peltiers have a lot more applications than commonly thought!

i cant see what wires you have going where with all those wires in the back lol! i am going to check and see if that looks similar to the step up motors i have., been out for a bit and was happy to see a new video... FYI will email you a idea i had about a dc air fryer/ confection oven

[@solarpoweredge]

@vrrevolution9183 There's wires everywhere, but they make things happen :) OK will keep an eye out for your message... FYI I am building a larger oven for solar/12/24v but haven't been able to finish it. The half-finished oven appears in my last VLOG

[@vrrevolution9183]

@@solarpoweredge i do not see it? is it on your website? please pass link

[@solarpoweredge]

@vrrevolution9183 It's a bit hidden... the VLOG was added on the end of my solar air conditioner video here. The oven is barely mentioned but it's all I have uploaded right now kzbin.info/www/bejne/aHqXnXtjbcSWedU

Hey Dave, love your videos! So I’m putting in a well which will flow into my lake. My thinking is DC pump wired directly to the panels. When the sun shines the pump pumps. Questions, will the price of a DC pump out weigh converting to AC ? Once the lake is filled up I want to do the same thing with a DC motor to aerate the lake. It will be quite a big solar array powering a heat pump for heating and cooling too. Again, thanks for your videos.

[@solarpoweredge]

@gordon6029 Hi Gordon, welcome! glad you like the videos and I'm thankful for your support! Sharing my own opinion here... converting to AC is always going to be an extra liability. The solar panel puts out DC, might as well consume DC. Then again, if you cannot find a DC pump, there is no choice. In any case I wish I had a lake, all kinds of cool projects could happen with that :)

When grid is down and I don't have the correct adapters and tools, I grab that good 'ol sickle and burn body lipids, not 100% efficient, but it gets the job done 💪 I'm just kidding.. your solution can be a life saver when need comes 🙂

[@solarpoweredge]

@SonnyDarvishzadeh Elbow Grease will be an important factor in grid down! Thanks for the kind feedback, hope this video gives people a few "just in case" ideas :)

Well of its cold it also adds heat to your room

[@solarpoweredge]

@james10739 True, maybe I'll try building one of those "spinning magnets" machines :D

[@bigmouthstrikesagain4056]

Is it possible to take a universal motor from a washing machine and then add windings and tap them at the desired voltages and then use that voltage to run stuff?

[@solarpoweredge]

@bigmouthstrikesagain4056 Hi, excellent idea. I need to experiment further, with 2 motors I found. One is a washing machine motor, the other is a different kind. If I build anything useful I will upload the results and share

Geee, that Bridge looks like a model KBPC5010 from here :) Haha ! Very nice little project/p.o.c. . Love your content !!

[@solarpoweredge]

@ianball3972 Hahaha! yes.. and I certainly wouldn't be soldering up several dozens of those 5010s to any solar panels for one of the strangest projects on record... guess that's the next video! :D thrilled you are enjoying the content, thanks for the positive feedback :D

Here I am again and again, not here to rain on your parade, but . . . There's an UBER-simpler way to produce dc or single-wave-form ac and even 3-phase with a little tweak. For now, consider this: Couple a dc motor (I use air motors, but I'm Autistic and do EVERYTHING differently 😅) to a flat disk containing neodymium magnets press-fit into holes. Make a sheet plastic circle with a hub (to attach to your input shaft) and holes in multiples of "6" about its perimeter and spin the array through a tweaked shaded-pole fart fan motor. Tweak = cut out a slot barely larger than your magnets' thickness, grind off the shaded poles & rewind the coil with thicker wire THEN . . . Place your magnets n-s for alternating- or n-n for direct-current and spin the wheel through the pick-up coil. Amperage is a factor of wire thickness, voltage (&frequency) is a matter of magnet proximity to the pick-up coil and rpm. That's it!

[@solarpoweredge]

@WhatDadIsUpTo Good thinking and good ideas man :D I am converting a brand new squirrel cage AC fan motor to an AC generator with neodymium magnets. Somewhere I do have a shaded pole motor, it's in one of these piles of stuff in my shop lol

[@WhatDadIsUpTo]

@@solarpoweredge I'm in the process of switching gears from low gear to high and when I have time, I'll throw all the ideas and gadgets onto videos and make it all open source, so others can join the party.

[@solarpoweredge]

@WhatDadIsUpTo Sounds like a plan!
