If you simply bury radioactive wastes where nobody can get to them, the problem is solved. The lifetime of a nuclear battery, on the other hand, is based not on its reactivity, but the half-life of its decay. By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies. How do you stimulate it? If you can lay hands on a large collection of defective EPROMs…, Honestly, you keep bringing it up! Learn more, http://gizmodo.com/5132765/soviet-atomic-lighthouses-are-both-spooky-and-deadly/, The High-Tech Valor Glass Vials Used To Deliver The Coronavirus Vaccine, The Mouth-Watering World Of NIST Standard Foods. So instead of using simply using Strontium-90, which is a well-known beta-emitter, it may actually be possible to use K40 (an isotope of Potassium), with a half-life of approximately 1.7 billion years. Time will tell as to the commercial viability of this product. The beta particles (electrons) from the tritium radioactive process causes phosphors in the device to glow, giving a light that can last for years. It doesn’t generate enough electricity to completely self-power, and that’s mostly because of inefficiencies in the feedback-circuit. I can recognize an electric typewriter and several other pieces of electronics test-equipment on the shelf, but what he pulls out of a shadowy area is unrecognizable. There’s hundreds of us complaining a week about false reports, they know. id say make a phosphorus silicone composite to replace the tritium casing / glass and the monocrystalline layer on the panel attach everything directly. Wonder if he could use a filter or lens to shift the wavelength to the ones he has? That’s also what makes the device Merlin showed me so incredibly intriguing: by using stimulated beta-decay, it produces more current on-demand, and the output drops to almost nothing when it’s turned off. So-called betavoltaic batteries were dreamed up way back in 1913. I bought one and 3Dprinted a parabolic case over it. (But of course if you need a hundred tritium gunsights well that’s just fine, for freedom.) Maybe safer to use nail varnish that sets under blue light. Do you know if he forward or reverse connected them as the absorption solar cell? Flyback transformers are used in television sets and HV-experimental equipment to step up a low-voltage input current to a high-voltage output, and can be further connected either directly to a rectifier diode or instead to a Cockroft-Walton voltage multiplier. “It’s a nuclear battery,” I tell him, “using a method of stimulating the decay of a nuclear isotope with a high-voltage to produce abundant, safe and clean electric energy. They are really just arrays of P-N junctions right? He gets 1.23 microwatts, not much, but it is in fact more than the output of commercial units at 0.84 microwatts, for a ten percent of the cost. :D, EPROMs are just big silicon die with a bunch of diffused transistors. You can daisy chain the power and ground pins of EPROMs to make a low output solar cell. Also worth trying: get some ancient photoelectric smoke alarms and pull the IR sensitive photodiode out of them. Here’s how it works: there are different types of nuclear decay, and Betavoltaic cells work on the principle of beta-decay. We don’t worry about the half life of the dangerous radioactive elements in the Earth’s crust, we just sit secure in the absolute fact that they are not going anywhere. everyone knows that beta radiation is a partical and not a photon, right? In a past life, he was Frank Stazny, a hard-working Boeing engineer, but after retirement went back to using a monicker he’d picked up in the 60’s and decided to invest his golden years in satisfying a child-like curiosity in science that had never waned. I’ve popped open a few older soldered metal top CPUs that are really big die but those might be worth more as collectibles than as science experiments…, This was my idea when I was a kid, except it was with glow sticks instead of tritium tubes. Steve Scott has updated the hackerspace titled CHAMP Makerspace. Never tried it since apparently you can’t get radium paint anymore. “Oh, they work,” he says, “Here’s one that I’ve been tinkering with for the last few months”. A commercial nuclear battery from City Labs. Learn how your comment data is processed. Learn about the compelling quest for a true portable, pocket-sized nuclear battery…. “I had to pry these out of the little epoxy cases that they’re normally housed in within the smoke detector”, Merlin tells me, “and they’re safe as long as you wash your hands after touching them.”. For the moment, though, it just rings …”. Jim, not true, I can detect a tritium tube with my geiger counter. Imagine a battery that runs for years on end, promising endless energy from a clean, safe, environmentally-friendly form nuclear technology. You may think that tritium is hard to obtain or even forbidden, however, recently you can find tritium in self-lightning key chains, and it is also used in watches and firearm night sights. The foil reflects light really well back at the panels. This basement is the “secret lab” of experimenter Merlin Del Orion — a white-bearded gentleman in his late 60’s that bears more than a little resemblance to his namesake from the age of Camelot. Maybe a better bet would be to get red trasers not green as the peak wavelength is closer to the peak on solar cells? I asked Bob if he’d ever considered building a nuclear battery with any of them. Hey NurdRage – if you’re going to do that, consider getting some 2N3055 power transistors from eBay and cut the metal tops off and try pointing the betas directly at the B-E junction. https://en.wikipedia.org/wiki/Betavoltaic_device, https://www.nist.gov/news-events/news/2016/06/physicists-measured-something-new-radioactive-decay-neutrons. A single crystal diamond large area thin membrane was assembled as a p-doped/Intrinsic/Metal (PIM) structure and used in a betavoltaic configuration. Potassium chloride is not much of a beta source. Jul 6, 2010 #3 wil3. In 6 days, a 1μA betavoltaic source could charge a 1.5 mAh Li-ion cell discharged by 10%. You’d be better off nicking an RTG from an old Soviet lighthouse, or perhaps a forgotten space probe. Denture Synth, OLED Keycaps, And SNES Raytracing, Bare-Metal STM32: Exploring Memory-Mapped I/O And Linker Scripts, New Part Day: Hackboard 2, An X86 Single-Board Computer, Netscape Communicator And SHA-1 Written Into Brexit Agreement, 3D Printed Server Case Holds 14 Raspberry Pis, Retrocomputing With Modern Hardware, No Emulation Required. (then change function). If someone removed the ‘glass’ from an EPROM…. This photocell idea is not a ‘battery’. You may not need one for your next electronics project, but we are sure you will enjoy his project. The trick is sourcing enough K40 for commercial applications, but McDonnough is actively working on sources for that. Surrounding one vial with about 40 BPW34 photo-diodes is likely to produce more power. He used the multimeter wrong. Some sort of diode-like thing that’s exposed to the isotope directly. According to Michael McDonnough, the founder of Betavoltaic, Inc. and an avid follower of Santilli’s work, “Potassium-40 is the perfect fuel for beta-decay because if the Betavoltaic cell is accidentally ruptured during operation K40 goes back to being extremely low in activity,” McDonnough tells me, “K40 allows us to throttle the isotope decay. If you want a light source that lasts for years but do not want to use radioactive tritium, consider the TritiLED. You get about 100mSv of radiation at the edge of the container. In other words, you get power when you need it, none when you don’t — a true battery. https://solarsystem.nasa.gov/rps/types.cfm. It’s in the same location as the reply button on reddit for crying out loud! Hmm, so 1.23 µW over 15 years equals 0.16 Wh. Step 2 - Attach Headers to the Top PCB. Dr. Santilli believes that isotopes can be utilized with such a normal low decay rate that they are considered for all intents and purposes to be “inert materials”. Please, please, please, send your battery to Dave Jones of EEVBlog.com. Since the electrons are emitted at high energy & high-speed, they disrupt other electrons when they collide with atoms, which allows you to create a “secondary current” at a lower voltage but much higher amperage simply by having them strike a correctly designed metal collector. Also, page 6 of this document tells how to calculate the theoretical yield of radiation on diodes. Nuclear batteries. What if you took tritium paint and painted it onto the solar cell(s). And there’s nowhere else for the light to go, than the solar cells. It is weak, but it is there. Good proof of concept though! But you might have gotten the bad batch that lasts 6 years. you could ballpark-it by comparing it to the Amps range ie 172mA vs 0.16A miiight be around 166mA, or just permenanently solder tweak-resistors while borrowing someone else’s meter to compare. With a non-stimulated half-life of 1.7 billion years, it would appear that that the K40 solution under development by Betavoltaic is the ‘perfect’ process for liberating energy in a controlled manner from the breakdown of this material. If Betavoltaic makes it work, they’ll be holding the key to an entirely new energy technology that has the potential to revolutionize our world through an inexpensive and efficient method of creating and storing electrical energy. Also mods you really need to move that report button. “Wait a second”, I tell him, “this nuclear battery technology is totally new stuff — even the person who was telling me about it doesn’t have a working prototype yet. An electrode stack is inserted into the resulting form to create a pouch cell. @macona: you may be detecting bremsstrahlung x-rays generated when the beta’s hit something in the tube. Certain nuclear isotopes emit electrons when they break down — these are called “beta-emitting” isotopes. The DVM I use most reads up to 2A before shunt needed. Merlin pauses to adjust his spectacles and frowns slightly, with one eyebrow curling up just slightly. Much cheaper than diodes. Just a thought. Same here, milliamp range is read on the voltage input. A Betavoltaic cell is a device that uses a radioactive source of beta particles and a semiconductor p-n junction to generate electricity. Just make sure the betavoltaic nuclear battery casing is more than a couple of millimeters thick — and don’t drop it. Build a million of them and you’ll have 1 watt. The basis for stimulated beta-decay technology comes from the theoretical research of Dr. Ruggero Santilli, who claims that with a specific static-charge applied to a nuclear isotope it can be made to break down at a sustained rate in comparison with a control sample. In 2016, Russian researchers from MISIS had already presented a prototype betavoltaic battery based on nickel-63. Best comment so far. Would using less viles together be more efficient? The nifty bit is the condition of the chip dies doesn’t matter, just that the power and ground are still connected to them. ???????? Now the next step would be to get a solar panel that was geared specifically toward the light wavelength of the fluid. Based on the betavoltaic and alphavoltaic effects, a 4H-SiC micronuclear battery was demonstrated. people who can NOT make accurate mA readings are usually the same people with this setup… it doesnt take long to shift the value of the current-sense reistor. Knowing that, you can build with extra capacity and be extremely certain you’ll still have enough power at some far off point in the future. Have you tried this with germanium? It’s only the extreme cases where this might be viable. I’ve just finished telling him about my encounter with businessman and inventor Michael McDonnough, and a remarkable new technology that I’ve heard about. I’m sure he can reproduce and improve your measurements, make another nice youtube-movie about it, and even perhaps come up with an energy-harvest solution to put it to good use. The only radiation to escape those tubes is electromagnetic, so solar panels are a pretty good choice. I don’t have the specific numbers myself, but you can predict to within a few percent the power output at any point in the 50+ year future by taking into account the decay rates of the nuclear material, the phosphor and the solar cell. I had considered that as well, sandwiching the source with two solar cells. The Ice Tray Battery You’re actually telling me what you’re holding actually works?”, “Yeah,” he responds, “It works. After getting rid of the plastic containers, he sandwiches the vials between two small solar panels. The lifetimes of betavoltaic devices depend on the half-lives, ranging from a few years to 100 years, of the radioisotopes that power them. You then suspend another wire inside of the glass vial, but not touching the rock — current will flow between these two wires, although it won’t be a large amount, and you can’t use it for much.”, Lazar told me that he’d actually built two or three batteries like this, and claims it’s simple & inexpensive, provided you have some radioactive rocks on hand. A chemical battery SHOULD last 10 years. Tritium, an isotope of hydrogen, is often used as the radioactive element. “Sure,” Lazar replied, “using a piece of radioactive rock to build a simple nuclear battery is easy. Rather than use Gamma rays and converting them directly, they take the brute force approach and stop all the radiation and let them produce heat. As shown in Fig. Betavoltaics are very much like photovoltaics, except that instead of receiving sunlight to make a current out of a solar cell, we are receiving beta radiation, caused by beta electrons from tritium. But for a hobbyist, handling raw tritium must be a pain in the arse, using the “beta -> light -> solar panel” method is simpler, if less efficient. Merlin walks over to a shelf in one of the racks covering the entire back-wall of the basement. “I put it on the oscilloscope a while back,” he says, “and it basically rings. I think to install atomic battery for my electric DC motor, I’ve been looking into building a battery/solar generator lately, and I was wondering how much tritium would be needed for the battery and if it would be feasible/possible to create a nuclear battery that large, say a 12volt battery powerful enough to drive a 1200 watt inverter? I am an engineer with a nuclear background and considered a design that can deliver 50 watts. I was thinking of photodiodes but i was unsure about them. Fab has updated details to pxlBlck - An IOT/SmartHome notification system. So you’d need 600 million little solar cells with however-many billion of those tritium tubes, which will conceivably cost more money than there is on Earth, probably. We are making a betavoltaic battery. To make stopping the radiation even easier they use Plutonium 238 which releases most of its energy as alpha particles that are easier to stop. World’s Largest Telescope To Finally See Stars Without Artificial Spikes, Scientists have 3D-printed the first-ever biomimetic tongue, Strange Worms Are Taking Their Place on Your Family Tree. A Betavoltaic cell is a device that uses a radioactive source of beta particles and a semiconductor p-n junction to generate electricity. Tehe, maybe use the tiny disc from a smoke alarm instead :D. True statement Miroslav. It’s pretty-trippy — it’s like a battery, but it’s nuclear.”. At temperatures that low most batteries freeze and some will even puncture their internal separators, causing them to short out if you bring them back up to room temperature. Nuclear batteries in the microwatt range are  used in clock circuits of critical computer systems and in some medical implants. Rather than being measured in hours or days, their potential lifetimes can be decades or even centuries. Of course, the amount of power you can get from this device is on the order of microwatts. In science, K40 is stable enough that it has little scientific use other than in studying biological systems using a highly bio-available and generally stable isotope. Step 1, Gather your materials. Oh absolutely. A novel betavoltaic technology with dyes for better energy production. Thanks! Dude, that could have been me… my BBS had 160 megabytes of storage! Might have managed to get a volt out of it. But now that I think about it, the major problem with mailing it to you is the fact that you can’t turn these things off…..it’ll be producing a high-voltage trickle of charge all the way through the postal system, which will set off all sorts of alarms.”. They are quite good at converting infrared to low voltage and the ones I found are maybe 0.8V >1mA under moderate flux. The schematics i’ve found for GPS loggers only have a limited battery life, so I was wondering if the radiation from the isotope could be used as a power source to aid and recharge the battery. Widetronix has built upon the continued innovations in semiconductor materials to make an extremely energy-dense betavoltaic. I was thinking about that- … 179 1. In this case, Merlin’s done something different, and wired it up to a round metallic ball rising from the circuit board on a post, almost like a miniature airport traffic-control tower. The ball contains a collection of maybe 20 or 30 small pellets. Merlin’s device isn’t perfect though — it won’t self power indefinitely after it has been initially activated. A nuclear battery is extremely predictable. It's possible to light an LED with a betavoltaic battery. Sorry just took troll comment for something actually useful, fuck me right? The physicists developed and manufactured a betavoltaic battery using nickel-63 as the source of radiation and Schottky barrier-based diamond diodes for energy conversion. I first learned about nuclear beta-decay batteries from none other than the infamous Bob Lazar, formerly of Area 51 fame. When you switch from volts to amps you need to use a different port on the meter… lol cmon nurd rage, most of my multimeters will read a couple hundred milliamps without having to switch over to the larger current shunt port. I’m planning on modifying the circuitry to allow it to completely feedback the electricity that the isotope generates through the stimulation circuit in the near future — that should let it run indefinitely, and after that I can attempt to draw high-voltage electricity from it to power other projects. Betavoltaic devices are self contained power sources that convert high energy beta (β) particles emitted from the decay of radioactive isotopes into electrical current. Technically it is illegal to even take apart a tritium exit sign to remove the tubes. Well, tritium decay also emits a neutrino, but good luck capturing that energy. Along the walls is a series of metals racks, filled haphazardly with a various assortment of tools, equipment, knick-knacks, and other oddities. Steve Scott has updated components for the hackerspace titled CHAMP Makerspace. If there weren’t phosphor or glass in the way of the junction maybe, is a solar panel a beta-voltaic in the opposite direction? But instead of absorbing photons from the sun to create energy, betavoltaics absorb radioactive particles, he said. Hackaday Podcast 099: Our Hundredth Episode! Essentially, when they break down a high-energy electron is released, which can be captured and used to create a small, high-voltage current. It’s OK, reports go to a human being, who’ll only zap the post if there’s a reason to. You can stack eight or nine cups to make a ~12 Volt DC battery. Its a cool hack, but I wonder in what case would it be better than just a simple lithium primary cell like CR123? Or get someone to nick a space probe before NASA get a chance to launch it. Probably best to point solar panels at the actual Sun. That minuscule amount of power is actually not easy to measure, and he does a great job explaining the circuit he used to measure the current. D. No, it wouldn’t, it’d be massively impractical. The betavoltaic battery isn't doing anything other than recovering the losses within the cycle so the fuel cell can create more power. It’s the middle of August and I’m standing in the basement of an aging brick house a few miles outside of Redmond, grateful to be in a cool area on a hot, muggy day. ???? Ultimately, that’s the problem with old-school Betavoltaic technology: it takes a good sized chunk of nuclear material to produce a usable current, and there’s no off-switch. You tried doing that and the DOE/NRC will be all over you. I wondered how much power that would put out. Also be careful with epoxy, it can crack the glass!! But you are right, for most people, even most professionals, a bunch of ultra-long life lithium batteries with some ORing diodes will give plenty of capacity and reliability for most projects which only need to last a few years at most. DGIST/Royal Society of Chemistry Electronic devices are becoming smaller, more connected, and more powerful; and they still have one thing in common: they need energy to function. This is just a fun project for those that want to add “Made nuclear battery” or “Built nuclear powered X” to their achievement list. Bottom line: RTGs are NOT gamma ray based. Essentially this means that K40 takes so long to decay under normal circumstances that its basically an inert substance — but when it does decay it releases an enormous amount of energy. The electricity given off by Merlin’s Americum-241 battery is accompanied by an enormous surge of high-energy protons & neutrons. In a hybrid design using both a NanoTritium™ battery and a lithium-ion battery, the Li cell would remain fully charged and last longer, even at high temperatures where the self-discharge can be 3% or more per month. Or else build your own, it’s only a KG or two of plutonium you’ll need, and the facilities to not die while you’re working with it.
