If you can lay hands on a large collection of defective EPROMs…, Honestly, you keep bringing it up! @macona: you may be detecting bremsstrahlung x-rays generated when the beta’s hit something in the tube. Not by much it would seem, He tried it with one solar panel at first. 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”. “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. If you’re really building a 20+ year device. Nuclear batteries in the microwatt range are used in clock circuits of critical computer systems and in some medical implants. 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 600watt? :) 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. If you simply bury radioactive wastes where nobody can get to them, the problem is solved. The mention of 20 curies in a fluorescing exit sign made me think twice. You turn it on and it applies a high-voltage to the nuclear material inside, and that causes the isotope to beta-decay & release electrons faster than they’d normally be emitted. Best comment so far. 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. Filters or lenses cannot shift the wavelength of light. Fab has updated details to pxlBlck - An IOT/SmartHome notification system. And there’s nowhere else for the light to go, than the solar cells. Jim, not true, I can detect a tritium tube with my geiger counter. (But of course if you need a hundred tritium gunsights well that’s just fine, for freedom.) 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.). 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. 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. I was thinking about that- … In 6 days, a 1μA betavoltaic source could charge a 1.5 mAh Li-ion cell discharged by 10%. 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?) The battery produces around 1.6 volts at 800 nano amps. unplug;safety-first You’d be better off nicking an RTG from an old Soviet lighthouse, or perhaps a forgotten space probe. 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. 179 1. 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. 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 foil reflects light really well back at the panels. :D, EPROMs are just big silicon die with a bunch of diffused transistors. A betavoltaic device is a type of nuclear battery which generates electric current from beta particles emitted from a radioactive source, using semiconductor junctions. Same here, milliamp range is read on the voltage input. Surrounding one vial with about 40 BPW34 photo-diodes is likely to produce more power. You tried doing that and the DOE/NRC will be all over you. It’s pretty-trippy — it’s like a battery, but it’s nuclear.”. Jul 6, 2010 #3 wil3. Merlin walks over to a shelf in one of the racks covering the entire back-wall of the basement. I’ll give them a try! I do exactly that to make alpha detectors, and alphas are much more easily blocked than betas. 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 should of used blue….. the spectrum emits more photons. If I get a chance I’ll try it out. They cost approximately $2,200, so you can figure out the price per watt. Didn’t even occur to me that was already where he was going with that. 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. Another working prototype, created at TISNCM and LUCH, was demonstrated at Atomexpo 2017. Have you tried this with germanium? It doesn’t do any harm. With a high-voltage static charge, at least that’s the claim. It’s a nearly perfect process, because it only releases energy under stimulation, and in the event of a critical failure it immediately ceases energy production.”. 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). 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. RTGs work on a different principle. In this case photons have a little easier path to the photo-voltaic? Epoxy surely blocks light more than air does. Never tried it since apparently you can’t get radium paint anymore. 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. Much cheaper than diodes. Apart from all the RTG’s powering, you know, most of NASA’s probes and rovers? 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. There are no viable gamma ray range photovolatic panels due to their extreme penetration depth. The most prominent tritium-producing reaction in natural lithium is Li-6(n,a)H-3. Such an advanced semiconductor device will produce much higher power outputs than are possible with existing state-of-the-art devices. 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. His only puts out about a microwatt. You may not need one for your next electronics project, but we are sure you will enjoy his project. A Betavoltaic cell is a device that uses a radioactive source of beta particles and a semiconductor p-n junction to generate electricity. After getting rid of the plastic containers, he sandwiches the vials between two small solar panels. 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. Based on the betavoltaic and alphavoltaic effects, a 4H-SiC micronuclear battery was demonstrated. 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? Or at least provide a popup asking for why you are reporting it, with the option to cancel. Would using less viles together be more efficient? Just make sure the betavoltaic nuclear battery casing is more than a couple of millimeters thick — and don’t drop it. “Betavoltaic cell?” he asks, questioningly. They then convert the *heat* itself into electricity using thermoelectric elements (peltier elements). An electrode stack is inserted into the resulting form to create a pouch cell. 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.  X Research source If you don't … Well, tritium decay also emits a neutrino, but good luck capturing that energy. The DVM I use most reads up to 2A before shunt needed. 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.”. 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. Those tritium keychain lights aren’t even legal in the US, technically. Those vials can be bought separately on ebay. Probably best to point solar panels at the actual Sun. Hmm, so 1.23 µW over 15 years equals 0.16 Wh. Like if you need something that can work at -100 celsius. D. No, it wouldn’t, it’d be massively impractical. Merlin’s device isn’t perfect though — it won’t self power indefinitely after it has been initially activated. Could a deadly mushroom help battle cancer?
