http://gizmodo.com/5132765/soviet-atomic-lighthouses-are-both-spooky-and-deadly/. 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 chemical battery SHOULD last 10 years. id say make a phosphorus silicone composite to replace the tritium casing / glass and the monocrystalline layer on the panel attach everything directly. Therefore a 1.0 uA Also mods you really need to move that report button. This means that after I turn the power off, the static charge decays very slowly compared to an inert test sample, which gives me a ring-curve on the oscilloscope. There are no viable gamma ray range photovolatic panels due to their extreme penetration depth. The beta particles from tritium decay are blocked by the glass envelope. https://en.wikipedia.org/wiki/Betavoltaic_device, https://www.nist.gov/news-events/news/2016/06/physicists-measured-something-new-radioactive-decay-neutrons. After taking into consideration the possibility that I might want to actually have children in the future, I decide not to ask him for a demonstration of the device — at least not today. Use your pliers to break off a few individual headers. anyway with a dc to ac power inverter and a Walton cockcroft voltage multiplier it might be possible to power a light bulb or a small radio ???? And there’s nowhere else for the light to go, than the solar cells. The lifetimes of betavoltaic devices depend on the half-lives, ranging from a few years to 100 years, of the radioisotopes that power them. Similarly, a blue tube surrounded by blue LEDs is also likely to work well. Those exit signs can be a total of 20 curies in each sign… quite a lot. The NanoTritium betavoltaic power source from City Labs is a thumb-sized battery that draws on the energy released from its radioactive element to provide continuous nanoWatt power for over 20 years Time will tell as to the commercial viability of this product. Would exposing the bare solar panel to beta rays maybe also result in some power or is the penetration depth too large (probably…)? Kohn called the idea of a commercially-available betavoltaic “intriguing.” “I’m skeptical it will be a market-maker, but it certainly has some niches it could fill,” he said. 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. Have you tried this with germanium? The mention of 20 curies in a fluorescing exit sign made me think twice. 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.”. In 6 days, a 1μA betavoltaic source could charge a 1.5 mAh Li-ion cell discharged by 10%. “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. If he turned the solar panels AWAY from the Tritium, they would produce more power :). I bought one and 3Dprinted a parabolic case over it. Electron-emitting beta-isotopes are capable of storing incredible amounts of energy in a tiny package — which means that a commercially feasible stimulated beta-decay battery would be suitable for mobile applications that require continuous power for years, perhaps even decades, without replacement. They cost approximately $2,200, so you can figure out the price per watt. Probably a little dangerous but it could be polymerised to make it stable then you could seal the assembly in a glass tube with the ends heated and closed off like a valve or light bulb. Such an advanced semiconductor device will produce much higher power outputs than are possible with existing state-of-the-art devices. Not certain if it would have the proper surface structure – planar – to make it work though.. 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. Hmm, so 1.23 µW over 15 years equals 0.16 Wh. Surrounding one vial with about 40 BPW34 photo-diodes is likely to produce more power. 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. In this case photons have a little easier path to the photo-voltaic? A friend won a prize in a high school science fair doing that with a dozen or so BIOS EPROMs he’d taken from dead and obsolete PC motherboards. Is the phosphor necessary? Do you know if he forward or reverse connected them as the absorption solar cell? Sounded fun to some kid dreaming of a 10w TEG to trickle charge my bat-cave 160M rig. So Why Hasn’t It Been Done? In addition, you'll need a pair of scissors, a voltage meter, and two electrical lead wires with alligator clips at both ends. Learn how your comment data is processed. Just make sure the betavoltaic nuclear battery casing is more than a couple of millimeters thick — and don’t drop it. There are nuclear batteries that use the beta radiation (electrons) directly. More power from a lemon cell. 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 was thinking about that- … xemone has updated the project titled SpotNano. I wanted to make an arduino GPS logger to attach to each container to automatically log the source movement (rather than the current paper method) as it’s, understandably required by law. Wonder if he could use a filter or lens to shift the wavelength to the ones he has? 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. Nuclear batteries. I do exactly that to make alpha detectors, and alphas are much more easily blocked than betas. I recall an old 80s BBS file or usenet post about painting a beta source into what was very similar to a large electrolytic capacitor and directly harnessing the emitted electrons though loosing their kinetic energy, maybe a mention of alpha emitters in balanced amounts on the other side of a dielectric, the late 80s were 30 years ago. 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. How do you stimulate it? Enjoyed your article. 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. If you simply bury radioactive wastes where nobody can get to them, the problem is solved. photon has an easier path to photo-voltaic… in that it is not a beta particle which is easily shielded. 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. The key to commercialization comes from stimulated beta-decay, based on the work of Dr. Ruggero Santilli, who claims that the rate of the decay process can be stimulated to provide electrical energy on-demand. They are really just arrays of P-N junctions right? Step 1, Gather your materials. Certain nuclear isotopes emit electrons when they break down — these are called “beta-emitting” isotopes. A Betavoltaic cell is a device that uses a radioactive source of beta particles and a semiconductor p-n junction to generate electricity. Bottom line: RTGs are NOT gamma ray based. My bet is it would end up being lower due to the energy cost on the wavelength shift. You’d be better off nicking an RTG from an old Soviet lighthouse, or perhaps a forgotten space probe. The beta particles (electrons) from the tritium radioactive process causes phosphors in the device to glow, giving a light that can last for years. Merlin’s device isn’t perfect though — it won’t self power indefinitely after it has been initially activated. Synthetic Life Forms Could Change Everything. It’s pretty-trippy — it’s like a battery, but it’s nuclear.”. Merlin explains to me that this device must be primed initially by being connected to the flyback transformer. What if you took tritium paint and painted it onto the solar cell(s). 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. Essentially, when they break down a high-energy electron is released, which can be captured and used to create a small, high-voltage current. “Sure,” Lazar replied, “using a piece of radioactive rock to build a simple nuclear battery is easy. 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. 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. I know that Merlin also realizes this, because the inside of the reflective metal-ball that the isotopes sit inside is lined with at least 1/8th inch thick lead-shielding. Step 2 - Attach Headers to the Top PCB. I don't think its possible to make a betavoltaic battery with potassium chloride and aluminum foil. Using these isotopes to create a “Betavoltaic” nuclear battery isn’t hard to do — according to Bob Lazar, it’s about as simple as putting a rock inside a glass jar. 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. Thanks! ... making it easier for them to then jump from the dye to the material on the other pole of the battery… I wondered how much power that would put out. Unlike solar cells, both leakage current and efficiency are important for photo-diodes so they work well in low light. There’s hundreds of us complaining a week about false reports, they know. Because you can connect one aluminum cathode (-) to the next copper anode (+). World Solar Challenge: How Far In A Solar Car? They aren't at all like miniature nuclear reactors. Of course, the amount of power you can get from this device is on the order of microwatts. “You know,” he said, “I could send you one of the little nuclear batteries that I’ve built — I think that you might get at least a couple of milliamps of high-voltage current from it. Lazar owns United Nuclear, which manufactures Geiger counters for use by the government and several commercial organizations, and one of Bob’s hobbies is collecting naturally-occurring radioactive rocks in the desert. I believe that’s exactly what the betavoltaic panels are desisgned to do, as mentioned in the video. We’re in the suburbs, but I feel strangely cut off from the modern world — hidden from the busy street by an abundance of sun-bleached weeds growing through cracks in the driveway. Many years ago I had the idea of painting a solar cell with luminescent radium watch dial paint. 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. But instead of absorbing photons from the sun to create energy, betavoltaics absorb radioactive particles, he said. Its a cool hack, but I wonder in what case would it be better than just a simple lithium primary cell like CR123? As shown in Fig. Or get someone to nick a space probe before NASA get a chance to launch it. http://www.ortec-online.com/download/Preamplifier-Introduction.pdf, (And if you’re interested in one already opened and the right type, contact me on .IO and we’ll work something out.). Also, page 6 of this document tells how to calculate the theoretical yield of radiation on diodes. An obvious question for a bright kid to think of is, “If there are solar cells that convert light to electricity, and radioactive waste puts out gamma rays for thousands of years, and radiation is just light, then why aren’t there panels to get electricity from that?”, Growing up, I finally got a chance to ask a real nuclear physicist that question, and he immediately answered, “because gamma rays are REALLY hard to stop.”. Filters or lenses cannot shift the wavelength of light. The 2N3055 is a silicon device. Step 3 - Make the Stack. The battery produces around 1.6 volts at 800 nano amps. Along the walls is a series of metals racks, filled haphazardly with a various assortment of tools, equipment, knick-knacks, and other oddities. One technology is a nuclear battery. 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. It's possible to light an LED with a betavoltaic battery. I asked Bob if he’d ever considered building a nuclear battery with any of them. 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”. 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. This study opens up a new horizon in the field of nuclear […] [1] X Research source If you don't … 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. XenonJohn has updated the project titled The Digi-Gurdy. Here’s how it works: there are different types of nuclear decay, and Betavoltaic cells work on the principle of beta-decay. D. No, it wouldn’t, it’d be massively impractical. The diagram shows the inside of a betavoltaic cell and explains the flow of electrons inside the battery. The trick is sourcing enough K40 for commercial applications, but McDonnough is actively working on sources for that. “Betavoltaic cell?” he asks, questioningly. Rather than being measured in hours or days, their potential lifetimes can be decades or even centuries. You won’t know until you wait that long and try it. 179 1. You simply get a glass vial and run a wire into the glass until it touches the rock — this is your positive potential. However, putting a radioactive rock in a jar doesn’t generate usable current and there’s no off-switch, making … Therefore, instead of a scant-few electrons being emitted from the isotope under normal conditions, the same isotope in a charge-stimulated environment will emit enough to generate a usable electrical current. But back in the day we only got about 10% efficiency.Plus I was lazy, so I dropped the idea. The basement is packed with tools, cabinetry, odd looking equipment, and all sorts of old, dust-covered electronics. I found my way to this article as I work in a laboratory that deals with 20-50Ci iridium-192 isotopes housed in depleted uranium containers. “I put it on the oscilloscope a while back,” he says, “and it basically rings. The lifetime of a nuclear battery, on the other hand, is based not on its reactivity, but the half-life of its decay. University of Missouri’s betavoltaic battery. Ever. Doing anything with tritium gas other than it’s intended product is a big no-no. I have always wondered how a solar cell painted with a gamma source and sealed would perform, perhaps it would just wear out like the pre tritium (zinc oxide?) You get about 100mSv of radiation at the edge of the container. Or at least provide a popup asking for why you are reporting it, with the option to cancel. IIRC he put 3 or for chains of them in parallel. A common source used is the hydrogen isotope tritium. Also worth trying: get some ancient photoelectric smoke alarms and pull the IR sensitive photodiode out of them. ???? I expected NurdRage to use the tritium to hydrogenate an oil then coat the semiconductor cell with that directly. It had a useful volume of 1.5cm3. The cross-section is highest for slow neutrons. Do you? The electricity given off by Merlin’s Americum-241 battery is accompanied by an enormous surge of high-energy protons & neutrons. Mounted on a 1-foot square epoxy circuit board, I recognize the familiar dull-green plastic case of a high-voltage flyback transformer, and after realizing what that component is I then recognize the multi-vibrator circuit that feeds it — a set of two transistors set to pulse at a specific frequency through the flyback to power the device. 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. everyone knows that beta radiation is a partical and not a photon, right? Steve Scott has updated components for the hackerspace titled CHAMP Makerspace. It doesn’t do any harm. You may not need one for your next electronics project, but we are sure you will enjoy his project. 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. You can daisy chain the power and ground pins of EPROMs to make a low output solar cell. Using these isotopes to create a “Betavoltaic” nuclear battery isn’t hard to do — according to Bob Lazar, it’s about as simple as putting a rock inside a glass jar. The betavoltaic battery isn't doing anything other than recovering the losses within the cycle so the fuel cell can create more power. An object lesson in why nuclear power, though safe, clean and cheap, needs to be properly and responsibly managed throughout its ENTIRE life cycle (whichis longer than yours by several orders of magnitude). I am writing a manual explaining some of the future technologies in my novel, “Texting and Teleporting”. If I get a chance I’ll try it out. Just a thought. Never tried it since apparently you can’t get radium paint anymore. You should of used blue….. the spectrum emits more photons. The electrons that are released during this natural decay process can be collected to provide electrical energy. It is weak, but it is there. :) Then when I watched NurdRage’s video on the Soxhlet Extractor where he was removing the plastic shell from the tritium key chains I thought “Those would be perfect for my old idea of a nuclear/solar cell battery. 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. 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. A nuclear battery is extremely predictable. Make four or five of those, and you can generate 60 Volts of DC electricity – not bad at all. …and lighthouses: He used the multimeter wrong. A nice safe fusion generator that’s thousands of miles away. Tritium, an isotope of hydrogen, is often used as the radioactive element. Instant power for the next 15 years. I recognize an oscilloscope, positioned next to a set of nearly 30 glass jars containing dried herbs. Other cases include needing absolute 99.9999+% reliability. The nifty bit is the condition of the chip dies doesn’t matter, just that the power and ground are still connected to them. Might have managed to get a volt out of it. I realize this is an old discussion but it occurs to me you could possibly see *some* gain by encasing the whole thing in clear epoxy (vibrating out any bubbles) to transmit the light more directly to the PV cells. Never got around to developing this because of the half life of a glow stick in comparison….
