Making A Gravity Generator From A Broken Printer 

Thanks. It's always fun taking things apart that don't have to go back together.

As a electronic technician im happy to say that was not too shabby of a connection I saw the solder shining and that's very important

Robert, your joy is always contagious to me. You may be like me in the fact that those bits of excitement and fascination are what did and continue to build a love for the science of things, especially energy generation. It's also nice to be reassured that saving parts from everything for future use, is perfectly acceptable lol. Thankfully my wife has seen many a good creation, or repair of something she thought was ruined, and thus fully supports my mostly organized "hoarding" of such things. You, sir, are the one living person I'd choose to meet someday. Non-living would be Nikola, of course. Thank you for all your work, it's excessively appreciated.

WOW!! I have literally just posted in another of your videos asking if you had made something like this! I have a printer. It wasn't broken the last time it was used but I can soon fix that! Will still keep my bicycle cogs, wheels and chains though! Thank you so much. Take care, Poo

Low voltage Schottky diodes would have increased the efficiency a LOT. With 0.3V drop per diode versus 0.7V drop for your silicon diodes (1.4V for each pair), you'd get 0.8V more recovered voltage, or about 31% more output. Realistically, a 40-60V Schottky diode will have around 0.2V forward drop at low current like that. That makes for 0.4V drop per pair, or 1.0V improvement, which would be more like 70% more output power.

I enjoyed a lot watching the video. I was delighted on the bridge rectifier part. Very simple and easy to understand. Thanks a lot mate!

i was thinking about this the other day... for instances where you have a solar or wind generation system, and your batteries are full, there needs to be a dump circuit so they don't get damaged... instead of dumping to a load, dump to a pulley motor to raise a weight to be used later for gravity generation.

for a moment I tought you where going to concoct a device that would generate gravity... from a broken printer! XD

No idea what I was expecting but always enjoy the ride regardless, you explain things well and with good humour thanks.

Its always refreshing to watch your videos ! 😁

That looks like great fun to do. I'll be in the look out for an old printer to mess with. Can't wait to try it .

Good Grief, Robert. I thought you were going to make a scale model of Artificial Gravity like in space or something. Getting a look at them innards was very cool.

Very nice project! I did'nt expect that the printer contains a 3 phase AC motor with a permanent magnet. Ok, you made it as a true gravity generator - hope you enjoyed this work as I did watching it: Almost funny how you dismanteled the printer. Thanks for uploading!

6:56 I'm liking the fixed iron idea, an interesting variation on fixing the wire/workpiece ! If we had any rain a system of recirculating buckets would make a nice downpipe generator.

As always new to me. I truly appreciate your work. I can't wait to get a membership. So I can see the rest of your incredible reworks and experiments. I am anxious to see you make nitroglycerin. LOL just kidding.

very interesting little studies you have here.. Great for guys like me that just like to tinker with things just to see what else can be done with them..

That was very cool! Synchronous motors work very well also and are geared internally but you probably already knew that. 😊

My first thought Great another Robert Murray-Smith video! Second thought Wait. Has Robert Murray-Smith gone mad from social distancing? Then after finishing the video for a few seconds I understood. Good show!

I have seen a system whereby a large generator is connected to a pulley system at the bottom of a tall metal pole. A heavy weight is lifted to the top of the pole using a rope/chain by a person manually then the weight descends slowly via a gear train which spins the generator a high speed charging a battery. It's actually an exercise/battery charger system. There are exercise bikes that do the same thing. Excellent presentation

Thanks sir, seems your intentions are pure.why can't others emulate

Sounds like a great charger for some lithium batteries for a small battery to run a lamp in a remote cabin . Just keep winding and then let gravity do the work. Fabulous! Reuse, recycle, repurpose. Brilliant!

Are any of your inks formulated such that they could be used in a laser printer or could they be? It would permit mass production of many of your painted on projects as well as increasing fineness of lines thereby possibly improving project energy density.

I thought you've lost it mr.smith, and then the intro...ohhh, yeah, that made a lot of sense, silly me (too much startrek). Great idea sir, not that difficult to do (presumably, since I've no laser printer junk insight). I'd do with inkjet though (just finding excuse to disassemble it), or maybe a fan, or some dc brushless motors, kind of like an old pendulum clock.

Nice. Easy - peasy , as they say. add a few pulleys, a Huygens endless chain and a simple rewind mechanism and you've got a workable emergency generator. Of course you would need to scale it up - just a bit.

Quick tip here: Service manuals for printers are generally quite easy to find. Just google the model and the phrase "service manual" in quotes and you are bound to find one. Not only will they make disassembly a bit easier, but they often contain a detailed list of specifications of the modules in the printer (like the various power supply modules) as well as a detailed BOM on component level, making it easy to find specs on the components.

That was great, and I think you are a great scientist and a wonderful person. But if you can put back together that printer you will be a GOD!!

While you were taking apart the printer you mentioned there being a rubber covered feed roller. Do you think that a pair of them might be suitable to act as a pair of powered, cylindrical squeegee rollers (like very old washing machines) for evenly applying (or perhaps removing excess) ink after dipping the paper sheets of your paper rheem battery?

Heath Robinson,... would be proud of you. ( String, weights and all) . Great stuff. .

@Robert Murray-Smith There was a Gravity Battery in use back in 1800'something built into a brick lined Well many weights used to drive a fan contraption of some kind.

Outstanding job :)

Ok I admit it: I was expecting Robert to somehow be making life easier for folk on the ISS using nothing more than a broken printer! But to be fair If any Non NASA type individual could somehow generate Gravity it’d be Mr Murray-Smith! Well done Robert thanks for making clever vids for planks like myself 😊 👍 Jonathan from South Wales 🏴󠁧󠁢󠁷󠁬󠁳󠁿

With the appropriate gearing even a small motor can be used to lift just about any weight. If the right circuitry is used the motor could switch from lifting when power is supplied to generating when a load is applied. A 1952 Buick could be used as a weight and store considerable energy.

is this a generator that makes gravity or one that runs on gravity to create electricity the reson why i'm asking is that i have been given the task of making a power plant that runs on gravity

The best motor I’ve seen for gravity, wind up etc gene’s is the small Synchronous motor that turns the glass plate inside Microwave cookers. As soon as the spindle starts to turn you immediately get 240V. This motor comes in 3 Wattages from 1-4W’s. They are great cos they are so small and don’t need any adaptations, I’ve been collecting chiucked out Microwaves for these motors( and the relatively large amount of copper wire they contain. Now I’m making a hand held Charger out of one of them, using an old face cream tub to put it in. I have 3 of these motors already, and two more Microwave cooker waiting to be taken apart!.

Liquid water is liquid at ground level... Construct a glass skyscraper made out of multi layered glass... The water will evaporate... It will condense at the top of the skyscraper due to water turning into a liquid as it cools down... Collect the water in a funnel and use it to drive turbines on its way back down...

Another good one my friend!

Next isolation challenge, build a flywheel battery!

After seeing your earth battery videos a question came to mind. Can two carbon fiber rods be used as the anode and cathode if a diode was placed on one to insure a single direction of current flow?

When I was a child I irked my parents by taking apart electronics (working and otherwise) with great zeal. I was deeply curious about what it made it do things it did. Many years later I took a course in computer repair and upgrade and having had the pleasure of turning out top notch machines ever since. So if you are a parent and you have a similar child who's driving you up the wall with similar activities of disassembly - get them an electronics course for their age even if - *especially if* - you aren't savvy with electronics yourself. Because if you learn it with them (or whatever they are interested in and passionate about), as neither of my parents did, your child will appreciate you for it for as long as they live rather than thinking you self absorbed and out of touch since Day 1.

Great video and idea. I had a similar one a while back but somehow building the mechanics of a pendulum clock. Maybe you could do that one at some point aye lol 😜👍

132 mW, not bad for a test (2.5v across 47 ohm resistor). You can work out the efficiency from the mass of the weight, starting height and time taken to fall now (mgh) / t = J/S = watts (mechanical). electrical watts / mechanical watts = efficiency.

Nice! I was going to 3d print one of these in the next couple days, but I think I'll just break a printer or 2 now.

What could you make with the rest of the printer.maybe a roller mill

An old automotive rectifier bridge from an alternator would be easier. It's an assembly using the same principle as your six individual diodes.

Hi and thanks for the info. Those printers are guar rented to withstand 7.5 on the Richter scale,we know this is because they are made in Japan.!

What kind of printer is it?

He said “just give it a tug and you’ll get it off”😜🤪

Dear Big Clive I know that you are watching this. Can you please do a video on the rectifier build as I only seem to be able to learn electronics if the person is speaking with a scottish brogue for some reason. 😁 👍.

Well now we need a long rope and high cliff to charge the phone. Lots of useful parts in printers.

So in theory you could use a reverse motor and once the weight reaches the bottom and hits a limit switch it would reverse the motor and generate current going backwards then another limit switch at the top to put it back forwards again. Then it would run forever and a day. You could measure out the string so that when it hits the bottom switch that the string is just reaching its full length from the spool. You are almost there mate.

I love your Gravity battery videos. and Gravity generators etc. The issues I see is that you have to get that weight back up on the drum to start the process over again.. fighting gravity as you do it, What if the weight floated back up to the drum? maybe Dry Ice ( carbon dioxide) as your weight letting it slide down a tube in a closed system. after the gravity battery does its job and turns back into gas, the rope comes to surface with little to no energy. the expanded vaporized carbon dioxide floats up the tube and is captured, compressed and made back into more dry ice weights for more gravity battery action... now the question is,, how much energy does it take to make dry ice? does the math work out???? I dunno.. I am not smart enough to come up with those numbers..

So you can bend space time with a printer?

Old printers are great, they're full of useful bits and pieces for the tinkerer/engineer such as high precision ground rods and rails, glass and plastic sheet, gear and pulley mechanisms, motors and sensors etc... 😁 But they can be a big of a bugger to open up....! 😋

6:45 mount soldering iron

Nice!

awesome as all ur other videos

Like 🖖 Spock used to say..."fascinating".

Imagine alot of these linked to solar panels to get energy during night and lift it up with excess energy during day 😁 sounds fun but I guess need quite the lenght to get some substantial energy from it aha

you blow my mind!

Hello, thanks for your work from Poland. Can you start ofered any of this on ebuy or else?

Yea, My old printers have step motors; Worthless for generation or any type of use without a pulse generator for exact movement. Usually you can find the data sheets from the part numbers on internet to know what you have. I was surprised you found a three phase motor - expensive engineering I would think. - an inverter?

Awww, I thought it was going to generate gravity. But then I suppose everything with mass does that.

I misread it , Ithought it said GRAVY generator !

Awesome! This device shows the Future problems with overheating systems! You need burn up heat quickly for save the Hawt or Vawt! With this you can create bas electricity! And Why! it is cheap and smooth! Old coal mines, cranes and Other solotions can take to chill off the generator and make it Useful again! For something we must have cheap bas electricity! This word is so silly and I wrote this if a Politician try to make a better World!

Your next video: How to restore to working order a broken up Printer ....

I wish I could see better about how the bridge retifire was done.. You should know, most of us doing these junk pile builds, just barely understand , household electric .

If you replaced the weighted wheel with a water wheel, two water tanks and a solar pump to recharge the system you'd have a small scale pumped hydroelectric energy storage system. Pumped hydro has a power density of "0.2 - 2 watt-hour per liter" (ref eesi dot org) Assuming the lower part of the range 0.2 watt hours per litre could be achieved on a small scale that would be about 20 litres to match the power capacity of an AA battery of about 4 watt hours.

So you just made a 0.026 Watt generator. .........

Lol! I've been doing that, taking old printers apart. The number of screw's in there is ridiculous! Given the fact that these thing's are more or less disposable object's, no one is going too fix a broken printer. They're just too cheap!

So your making gravity are you 😃 NASA wants to have a chat 😃

Gearing

Didn't work you use the same amount of energy to lift the weight up there, So you want energy to lift it up there say from a solar panel, basically all you have is a battery that stored the energy

☺😊😀😁😂5 Smile's
