Containing 'electromagnetic pollution'

A group of researchers is working on cleaning up electromagnetic pollution by containing the emissions with a thin coating of a nanomaterial called MXene.

Thanks, I know someone who is researching and going to give a presentation on this topic later this year.

Thanks for info on MXene, MaXine. (Sorry.)

A leaner lighter Faraday Cage is sorely needed, so this is good news.

As well as inter-device shielding, maybe MXene could also confer some solar flare protection if there's a Big One.

Or just protect us from sunburn when a walk in the sun fells so good. I'd buy that. But, I don't think that's what they are talking about. Seems like every time we improve something we find we've created another problem. Microwaves? Overhead wires - heavy ones. Wind farms for birds to fly into. Even picture windows to injure birds. Same on stores to injure people.

Progress marches on. I mustn't be a pessimist. By the way, what is a Faraday cage?

Basically what this new stuff does. It blocks electromagnetic fields. A solar flare can cause intense EMP events, electromagnetic pulse, at the earth's surface, as happened in the "Carrington Event" of 1859. Some important electronics is Faraday caged already (defense stuff, especially, as one might expect), but a lot isn't. A huge EMP, caused by a CME, a coronal mass ejection from the sun, could fry electronic chips in cars, computers, phones, servers, etc. And severely harm transformers in our power grid. And don't forget our friend the H-bomb, which also unleashes a huge EMP, indeed that was one of the tactical scenarios during the Cold War, that an ICBM could, at the right altitude, detonate and take out most of the circuits in the continental US.

Cheering stuff, eh.

Well-put, Biv. Fact: We are a people who tend to wait until a tragedy hits before we act. Conclusion?

Hi Viv,

Thousands of years ago we used rocks for weapons. Then Clubs, Then Spears, Then Arrows, then Canon Balls/Guns, then explosive Shells, and now the Atom is unleashed. This natural escalation of weapons will occasionally lead to tragedies of an escalating nature/magnitude.

Conclusion?
We are doomed...lol.

Best wishes,
Dave :^)

I won't argue with that. Voices crying in the wilderness. But it does make me ask again. Are you sure we want to start over? Do you really thing we'd change our ways? How do we change our "how to do it" philosophy?

Hi Viv,

There is hope. It's a race between figuring stuff out and a doomsday scenario. See the other thread for more detail (Naming Stuff).

Best Regards,

New novel looks at what happens afterr a massive CME strikes Earth.

BTW, the Future Tense channel has a lot of interesting bits on emerging technologies and their effects on society....
