What's the most fascinating structure or object you've been inside of? in c/[email protected]

The steam tunnel system under that big midwestern university. Once in, it led underneath most every building on the campus. There are many other mysteries hidden in the underground -everywhere-.

What happens if you leave your phone off the hook? in c/[email protected]

Wow. I can't believe it took me so long to learn about that. And no tour needed. Interesting, thanks!

E-Scooters become more affordable for low income riders in c/[email protected]

That's a lot cheaper than the laughable $1 + 45 cents per minute Lime is charging for their bikes where I live... $28 for the first hour. HA HA

Federal Appeals Court Finds Geofence Warrants Are “Categorically” Unconstitutional in c/[email protected]
[–] [email protected] 11 points 1 week ago* (last edited 1 week ago)

A geofence is an imaginary boundary around a location. If police get a 'geofence warrant', they can request a list of all phone#'s (and so their owners) that were in that area for a particular period of time. The court ruled this is too invasive for innocent people in that area.

Thanks for ruining the joke in c/[email protected]

That is one of the drawbacks of not having to carry a dictionary around ... ever again!

It wasn't that long ago that the 'It Gets Better' movement showed up. (Dan Savage: https://www.youtube.com/watch?v=7IcVyvg2Qlo )

It's still out there! (More info here, e.g.: https://itgetsbetter.org/

Being also old, I decided only to be on the death lists of people that didn't just want something from me. So, it may go unnoticed.

California lawmakers negotiating sweeping package to speed up solar, wind energy in c/[email protected]
[–] [email protected] 3 points 2 weeks ago

Legislators this year already are trying to tackle the rising costs of electricity.

Considering CA's widespread use of the now-cheapest sources of electricity, it's more than ironic that costs to consumers are rising. Somebody needs to take a -very close- look at that.

Another question for CA: are data centers required to be carbon-neutral or else ? Will they thriving on the savings created by people driving EVs? Will their demands result in higher prices for everyone?

Hmmm. Where can a person learn the facts about this ... 'agenda' ?

Scientists Propose Lunar ‘Noah’s Ark’ to Preserve DNA of Endangered Species in c/[email protected]
[–] [email protected] 8 points 3 weeks ago (4 children)

For very long-time, high-probability safety, the surface of the Earth is constantly being re-shaped. Whole mountains can disappear in a few million years. Floods, earthquakes, ice, weather alone.

Why Is the Oil Industry Still Thriving? in c/[email protected]
[–] [email protected] 10 points 3 weeks ago

Because you can fool some of the people all of the time, and all of the people some of the time ... and they've been at it for a very long time.

Svalbard's a 'seed vault' only, there must be something for extinct animal species. Another question I thought of: if stored on the moon, who among the finders will know enough to even know that they're looking at? let alone to make purposeful use of it?

This Incredible Tool (preventing insolation) That Our Ancestors Used To Keep Cool In The Summer.

Yeah, they cost money. So does installing air-conditioning. But they use no energy ( that'd would be bad for fossil energy-producers).

An experiment doled out money to homeless people in Denver, no strings attached. Here’s what happened. (coloradosun.com)
 

They were separated into three groups. Group A received $1,000 per month for a year. Group B received $6,500 the first month and $500 for the next 11 months. And group C, the control group, received $50 per month....

And ... no surprise ...

While the report is focussed mainly on the U.S., its detailed perspectives, timelines and responses apply widely.

Neutrinos: The inscrutable “ghost particles” driving scientists crazy (arstechnica.com)
 

We haven’t pinned down the masses of any individual neutrino, and we don’t even know which ones are heavier than the others. When it comes to our ability to collect raw data, neutrinos present a triple threat: they’re incredibly lightweight (even the electron weighs over 5 million times more than all the neutrinos combined), they shift their identity as they travel (and their rate of flavor oscillation changes as they travel through different substances, so there’s no one-size-fits-all solution), and they barely interact with anything in the first place...

The world’s largest fungus collection may unlock the mysteries of carbon capture (arstechnica.com)
 

Soil is a huge reservoir of carbon. There are around 1.5 trillion tons of organic carbon stored in soils across the world—about twice the amount of carbon in the atmosphere. Scientists used to think that most of this carbon entered the soil when dead leaves and plant matter decomposed, but it’s now becoming clear that plant roots and fungi networks are a critical part of this process

Energy buffs give small modular reactors a gigantic reality check (www.theregister.com)
 

With a few SMR projects built and operational at this point, and more plants under development, the Institute for Energy Economics and Financial Analysis (IEEFA) concludes in a report that SMRs are "still too expensive, too slow to build, and too risky to play a significant role in transitioning away from fossil fuels."
