yeah, since efficiency is usually a measure of how much energy is lost to heat, should be 0% vs 100%... but, marketing.

I also doubt they are using aerogel or cryostats insulation to surround hot bricks. (or maybe that's why 1 container costs $9M?)

Matt (and team) from Undecided almost never approach their videos with a critical eye. Many startups' claims can be debunked with high school physics, but they just present everything as-is and with good production value. I consider their channel more entertainment than education, but still interesting to see some of the ideas out there.

Ok. I like the concept….thermal mass as short term heat storage/release is a well established science.

Sadly calling bullshit when they claim converting electricity to heat is 100% efficient. Nothing is 100% efficient.
They also claim 98% efficiency “pulling the heat back out”…unbelievably high.
Noticeably missing were heat loss rates, both for capture and storage over time…both expected to be extremely high at temperatures of 1500C.

The second system boasting 80% efficiency (but why burning wood?) is more realistic, but the only 3% heat loss per day at 500C temperatures claim is not. No insulation I’ve ever heard of is that efficient.

Recycling industrial manufacturing heat seems smart, but I think they need to be honest up front about the real world expectations and uses. If it could cut the energy needed to bake limestone or melt steel in half, that’s great…please don’t imply it could cut it by anything approaching 97%. That makes me not trust it at all.

I see….they have a much different definition of “solved” than I do.
I think that word indicates the completion of a solution to a problem.
They mean simply beginning to address the problem, sometimes just agreeing there IS a problem.
Don’t get me wrong, all these are *quality steps in the right direction, but very few were actually solutions by any stretch.

For instance….#18 is a local concern.
This is far from the first time Klamath River dam removal has been scheduled for “next summer” only to be delayed time and time again. This has stretched out for so long that a few species of salmon the removal was supposed to save are no longer detected in the river. Multiple drought years and heat waves paired with mismanagement and neglect have spawned multiple full river toxic algae blooms making the water poisonous even for swimming, lots of dead dogs, lots of dead and sick wildlife, millions of dead fish.
It wouldn’t surprise anyone if new challenges to removal are started based on that alone, further delaying removal until all strains are gone.
20 years ago the Klamath was a world class salmon river, today it’s often closed to fishing even for native tribes that subsistence fish to survive.
I hardly consider another new projected project START date for the multi year 4 stage removal project to be “problem solved”. After that part is finished, massive river long restoration STARTS. If that can be successful at all, it takes decades and mountains of cash.

Sorry to be a Debby Downer.

Get that dog some booties.

"If your dog spends a lot of time outdoors — whether in summer or winter — investing in dog boots is a good idea. Paws are sensitive to extreme heat, extreme cold, and sharp particles such as ice shards or sticks while hiking."

Today terrorist Trumpists “took credit” for the terrorist acts over the weekend across the nation, cheering them and hoping they did maximum damage to America. Also their communications about their plans to attack power grids were discovered.

In N Carolina they have all but said they were the ones who shot up the power grid, “we know why the power is out” “god works in mysterious ways. (Wink)” putting thousands in the cold and dark for days during a winter storm….and their digital communications planning it support that. Apparently this was done to disrupt a local drag show scheduled for 7pm Saturday, right after the sub stations were shot up causing millions in damage and freezing over 36000 people in their homes without heat or power.
In Florida militant Trumpist terrorists attacked drag shows with violence.
In Ohio they attacked drag shows and gay clubs, shutting off power, blocking all access in or out, taunting them with another mass shooting while dancing to YMCA (because you’re too stupid to know it’s a gay anthem about loving public gay sex….or more likely because y’all love public gay sex while you scream how hate it….that’s much more Republican.)

More death, destruction, and debauchery by the now publicly anti constitution anti democracy anti America terroristic Republican Party.

It’s ok Bob, I know you likely blocked me after you lost the election despite your still posting questions to me. You aren’t adult enough to stand behind your statements or hold a conversation, especially while every prediction you made in the last year fails to materialize and you lose your shirt while the right loses its clout, because you are nothing but an anti American troll…and likely really 14. I don’t expect you to have the testicular fortitude to respond….but you deserve a daily reminder of the anti American terrorist your messiah Trump has turned you into.

Firstly, there are many different methods for human composting, including just burial in a biodegradable box without preservatives. At cemeteries, plots might be slightly more expensive because they’re more spread out, but beyond that it’s the same cost as any burial.
But yes, I would absolutely pay the minor difference in cost to not waste resources (both my nutrients and the gas burnt). I have no heirs.
I would much rather be a tree than a toxic plot of grass. I think anyone visiting me would be happier with that too….but it’s much more about the environment than people for me.

Again, because this one method is costlier doesn’t mean it has to be. This method is really partial cremation. I would consider something more like this….

https://www.popularmechanics.com/science/environment/a34054806/living-coffin-helps-bodies-decompose-faster/

Or less. Those cost less than most coffins.

People used to just go in a pine box and they composted quickly…none of these preservatives in the body and steel coffins designed to last centuries, that’s insanity to me and I want none of it.

Unfortunately the land fill would be a rotting cesspool of decaying bodies if people could toss bodies into dumpsters. Maybe consider donating to science, then they pay for your disposal.

Edit: this reminds me of the above ground cemeteries in New Orleans that (according to our tour guide) use the natural heat to naturally cremate bodies then they just push the last remains to the back of the tomb and reuse it.

ok, I get the frog thing (other magicians have done that). and the whole box of nails were trick nails (Jimmy didn't have a magnet or pour water in the bowl), but I don't understand how they got the entire audience to end up with the same card?
at least 1 would have not followed the instructions correctly...
could be the whole deck was activated by body heat (to change to 5 of hearts), hence the pocket or sitting on it?
Notice Jimmy put in his outer jacket pocket and didn't have it on the whole time - maybe that's why David didn't ask him to look at it at the end?

Truly there should be a helping hand to bright students who can't get a scholarship, loans to to to higher education.


I was poor student , didnt care about it got low grades. -- A year of washing dishes made me think find a white collar job. Dad refused to pay / help. I ended up getting student loans.

Dads motto -
IF you want something bad enough you will find a way.

Dad was a HS grad and was writing quotes for Navy Nuclear and many other million $ bids. Smartest man I know.

Paid my way through Penn State, slept on the floor, no heat 1/2 year ---- but I did it . Paid back my student loans and I am a better person for it.

higher education should place a finical burden on you - You will work harder because you can't afford to fck around.

That being said college / universities are over charging and raping students more and more every year.

? do college charge more because they know that the student can get the loan? I think so.

I think If you drop the amount a student can get in loans I sure tuition will drop to that level --- Supply and demand.

Lol.
Reasontv, the network of the insanity from Stossel, with the stated position that “free market and deregulation is the solution to any and every problem imaginable”. That’s the best you’ve got!?! Then you’ve got NOTHING. You actually complain that CNN isn’t trustworthy, then you post from Reasontv!?! Er mer gerd! 🤦‍♂️ why not just post Beck or Jones?

They completely misrepresent what the report, and climate activists, and politicians have said with bad editing and lies here, no surprise, you posted it, it was guaranteed to be DISHONEST nonsense propaganda.

Land temperatures reached 1.3C above pre industrial norms in 2020. Every prediction made has come true well ahead of schedule. Temperature rise is accelerating, it’s not the flat straight line nor a slowing rate like they showed but an increasing curve. The last 7 years were all in the top 10 hottest ever, the last decade had 9 of the hottest ever, and we are experiencing a global drought never seen by modern man….but according to you, nothing burger, totally normal, chicken little.

https://www.iflscience.com/nine-of-the-top-10-hottest-years-ever-all-occurred-in-the-last-decade-62232

There is one thing I agree with, the “12 years to stop climate disaster” notion (not what the science says btw) is wrong. We have -20 years +-. The CO2 we put in the atmosphere today will effect climate for hundreds to a thousand years, the nitrous oxide for about 120, methane around 10. We have reached the point where natural emissions will soon take over, adding more than humans ever did. Scientists estimate that’s at 1.5C, but every estimate they’ve made public has turned out to be optimistic in the extreme, so 1.5C is almost certainly wishful thinking and 1.25C is more likely the threshold. We can both mitigate the effects and slow the rate of change, but at this point staying below 1.5C is a pipe dream no one is actually even working towards.

I think the reality is that, using current models, assuming no surprises or feedback loops, we have (now 8 ) years before the adding these greenhouse gasses in the atmosphere will carry us well beyond 1.5C above “normal” with no additional emissions needed….not that we will definitely hit 1.5 by 2030 but we will be able to coast there even with zero emissions.
I know, math and science together, way too hard, better to just listen to the oil spokesmen who say “it’s a hoax, pay no attention to the cities reaching 130F, the unprecedented heat globally, the rapidly melting (or melted) glaciers that historically provide drinking water for 1.9 BILLION people, or the never before seen by man extreme global droughts, they’re all normal and natural and why are you still talking about it?”.

No surprise, one more undeniable, in your face disaster you simply deny exists….like Covid, Jan 6, Russian election interference, -3.5%gdp, Trump terrorism, etc.
Can we have your name so when the global food supply is insufficient we know who’s family to deny food?

Crop failure by 2030!?….oops, try 2022.
Unprecedented drought and unheard of global temperatures right now. Massive crop failures worldwide, and more just not being planted for lack of water.
We aren’t on the road to global catastrophe, we are knee deep in one. Thousands if not tens of thousands will die This week in Europe as a direct result of human caused climate change. Over 1500 died in Spain and 1000 in Portugal from heat just in this one event, over 4200 across Europe….so far. Crop losses will multiply that exponentially.
We are on the downhill ride into mass extinction and we already ripped our brakes out and pulled the steering wheel off and are arguing over how hard to stomp on the accelerator.
If the ecological cost of burning gasoline was included in the price, it would be well over $10.

A car would be a perfect place to shelter:

1. The windscreen blocks UV light.
2. A car isn't going to collapse on you.
3. The car has actual shock absorbers to absorb the ground shock.
4. The car isn't innately flammable and even has a thermal barrier in the paint, metal and insulation.
5. The car has a radio.
6. The car is mobile and can (to whatever degree roads are passable) get you out of danger.
7. The car has a trunk to hold containers of water safely (double-safely if they're inside an ice chest inside the trunk)
8. You can sleep in a car.
9. In any circumstance in which a car was destroyed by the blast/heat, you were fucked anyway.

When your grasp on reality is broken, you can be convinced of any nonsense.

I wonder how this man profits from spreading this misinformation.

So you know, bob. Oil isn’t made out of dinosaurs, it’s made up mostly of decomposed diatoms, algae, zooplankton, and other microorganisms, transformed under heat and pressure.
It is a finite resource.
If we burn it all, it’s CO2 emissions alone would cause an estimated approximately 200 ft of sea level rise (and likely near total planetary extinction).

PS- shouldn’t it be “The oranges of oil falsely defined in 1892”?

the rub of "good guys w/guns" is the "good guys" requirement.

if the argument is "those that can be proven to be responsible, safe, and sane can own guns" then why fear the 'proof' part of the equation?

it's in their motto!

'bad guys' helping 'bad guys' get guns is bad guys, bad guys...whatcha gonna do?

plus

the idea that teachers/school kids can be expected to keep the doors closed - turn on the a/c or the heat up and just see if YOUR home doors are kept shut!

more fantasy from the infanticidally idiots. as if the uncompromising are themselves 'compromised'.




just think...this song is 30 yrs old...and it doesn't raise an eye brow now...
