    Hmm, but doesn’t this require strong magnetic fields, that are potentially problematic? For example, wouldn’t your spoon heat up from induction, if you place it close to your phone?

        Cancer, not at all. This is not capable of generating UV rays. Heck, not even visible light.

          Right, I wasn’t under the impression that it did. But radiation does exist across the electromagnetic spectrum. Are they able to calculate the long-term exposure amounts and deem them safe?

            Yes. Not all radiation has the capabilities of causing cancer.

            Look up ionizing radiation. You need that to damage cells.

            That begins at the middle of UV spectra. Less than that, it can’t (it’s related to the photoelectric effect and Compton effect)

            You cannot make visible light to produce cancer. It’s not physically possible. And microwaves, wifi and cellular radiation has less energy than visible light.

              @kier I am no expert, but there are I believe other mechanisms that could *maybe indirectly* cause cancer with certain kinds of radiation. I feel like cell damage from microwave- or infrared-induced heat could release free radicals or create some other carcinogenic chemicals.

              But that’s not a direct result of the radiation. Direct DNA damage from radiation only occurs with ionizing radiation, as you mentioned.

              And since we’re talking about visible light, I’m not aware of any way, indirect or otherwise, that visible light could cause cancer.

      My take on the down votes is this ventures into conspiracy theories about Tesla and wireless power delivery.

      The only reason I can think of for people to be downvoting you is if they think you’re talking about the car company, not Nikola Tesla. Probably should have used his full name.

      Though the system he came up with was, well, flawed for lack of a better word.

        It was pioneering, but viewed as mad science. It wasn’t a workable system, but had other scientists ran with it, it could have become something a lot sooner than 2023.

      I thought he accidentally gave a bunch of his assistants cancer with his wireless power transfer or something?

        Jesus fucking Christ no. That’s not how any of this works. Please delete your comment in case some stupid ai bot eats it and tries to pass it off as reality.
