Clickbait BS: "If approved for use in devices like smartphones, future generations of the battery would ultimately remove the need to ever charge them, company representatives said." The battery is around a cube centimetre , a mic

I have a compliant : sometimes there a proliferation of anti-scientific posts, in example I can mention those related to the "50 years nuclear battery", I remember particularly one from techradar.com that was especially misleading

It's a bad idea for many reasons: - you are spending hundreds of millions for a prototype , on paper all works but in reality to build a reliable submarine you need peoples, experience, tests etc, to avoid something like this: https:

Following your reasoning an airplane can't be hijacked because it's difficult to operate: in reality you only need a gun to operate anything, in right circumstances.

I guess like you do for airplanes: the fact a plane can fly don't make it immune to hijacking. Example: you wait the sub is in the port, is moored, etc

PS: NASA , I really want to watch the mission live on TV, like my grandfather, so please don't make flying pigs.

I agree, this reminds me RFC 1925 ( https://datatracker.ietf.org/doc/html/rfc1925 ), that states: "With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure

P.s. Reading patent details: "to prevent the at least one radiation from having any wavelength that is outside of the range can be provided or which can be substantially harmful to cells of the body". What means "substantiall

the answer is no, I was reading the linked documents and: 1. yes UVC of that frequency kill virus but they don't provide results about human safety, the say "potentially": "Germicidal ultraviolet light, typically at 254

1. absolutely no, the article talk explicitly of "phones and drones"; 2. No, it's related to "phones and drones", I've explicitly written that this device make sense in niche application, microvolt application

I think you are trolling, but, in case I'm wrong, I explain the concept in other words: modern phones need a charger able to provide current to the phone battery in order of Amperes (A) the one is on my desk now is 5A and can charge th

It's not matter of skepticism, it can't work and it's matter of science, it doesn't work both as generator to "recharge" the battery (at microwatt scale it needs years ) and as generator to directly power &quot

P.s. More critical thinking is required before reposting this kind of article, those are, anyway, all very similar: computer generated mock, no test, no prototype, no scientific documentation, no peer reviews. Only a before-unknown company

No really, no. It's the same to declare that you have a box of matches and burning them it gives you a substantial help to warm up your house in the middle of winter. "which measure less than a coin at 15 x 15 x 5mm" , if you

"The compact battery uses 63 nuclear isotopes to generate 100 microwatts and a voltage of 3V of electricity through the process of radioactive decay" So the battery produce 0.1 mW or 0.0001 W: what "phone or drone" works

I'm wondering why there is no measurement, no data about the radiation detected. All in our environment is a little bit radioactive, it's called background radiation : https://en.wikipedia.org/wiki/Background_

Are you sure of that ? I knew that the competent jurisprudence or "forum" is that of the user, or everyone could circumvent the law using "offshore" companies to track people in regulated countries (i.e. EU). I was readi
