You only have to be able to see ~ 5 ft to play golf well. If you see the club contact the ball, it has a chance to go straight, and you get to see the sparks.

The titanium end cap looks like it worked ok. No visible evidence of the Home Depot bolts holding it them to the hull.

"Blamed by some, hailed as heroes by others, those involved with Fukushima Daiichi face a deadly, invisible threat — an unprecedented nuclear disaster." Sound like a movie pitch. Oh, wait. Different, when you know the end before it starts. Physics isn't fiction, it's an absolute. Excellent subject matter, Chernobyl 2.0.

Probably posted upthread, but always fun to watch the true meaning of FAFO.

RIP Professor Goodenough. "John B. Goodenough, professor at The University of Texas at Austin who is known around the world for the development of the lithium-ion battery, died Sunday at the age of 100. Goodenough was a dedicated public servant, a sought-after mentor and a brilliant yet humble inventor. His discovery led to the wireless revolution and put electronic devices in the hands of people worldwide. In 2019, Goodenough made national and international headlines after being awarded the Nobel Prize in chemistry for his battery work, an award many of his fans considered a long time coming, especially as he became the oldest person to receive a Nobel Prize. “John’s legacy as a brilliant scientist is immeasurable — his discoveries improved the lives of billions of people around the world,” said UT Austin President Jay Hartzell. “He was a leader at the cutting edge of scientific research throughout the many decades of his career, and he never ceased searching for innovative energy-storage solutions. John’s work and commitment to our mission are the ultimate reflection of our aspiration as Longhorns — that what starts here changes the world — and he will be greatly missed among our UT community.” Goodenough served as a faculty member in the Cockrell School of Engineering for 37 years ..."

Renewable Energy Saving Texas' Ass Right Now
PTINS replied to Horn Under a Bad Sign's topic in Daily Texan
I haven't been here since the freeze, just came by to get the pulse, and offer an opinion ... So, the Energy Vault will store energy produced at $X cost, and redeliver 80% of that energy back into the grid, when energy costs are higher, $Y cost, with $Y >> $X). The underlying premise being that the cost savings ($Y - $X) will offset the 20% energy lost in the transfer, as well as the capital and operating & maintenance costs of the facility. Okay. Newtonian physics; energy cannot be created or destroyed, and ... you can't even break even. They (one of you money guys) need to co-locate these energy vaults at container ship offloading sites; the cranes already have the containers way up in the air, just load them in a facility, harness the gravity generated energy, load the containers on transports, rinse & repeat. Maybe adds a day or two to the supply chain. Yesterday was an unremarkable weather day for summer in Texas, play ol' hot with a lot of sunshine. Peak renewable energy production was ~ 48.9% of the total (~ 28,000 MW), occurring ~ 9:30 in the morning. Peak demand occurred ~ 78,400 MW around ~ 5-6 pm, with renewables production of ~19,400 MW making up 24.8% of the total. The rhetoric and the raw data (from Texas anyway) don't quite support each other, as the peak renewable production (9-10 in the morning) is out of phase with the peak demand (4-6 in the afternoon). At least on this particular day, the lowest wind production occurs during the 4-6 pm peak demand period. This surprised me; all my younger days spent driving 500 miles a week across west Texas taught me that the wind picks up later in the afternoon. I would not expect that the wind gets high enough to "cutoff". Doug may be a good follow, but for my first reading, he has an agenda. There may have been "high levels of fossil fuel outages", but the net effect is those outages had zero effect and the incremental power demand during the normal daily profile was met with increased fossil fuel production, including the offset attributable to renewable production decreasing during the day. I support whatever energy source that can can improve the cost and reliability of the overall system, but masking the true cost/benefit of each contributor through rhetoric, credits & subsidies only blurs the picture and benefits individual producers at the expense of consumers. I know some of the larger renewable producers earn significant tax credits, which they apply to their oil & gas production, for which they end up having a zero tax obligation. That is the only way they can monetize their renewable credits, playing by the rules, and not paying taxes. -
WTF? Why do my posts all have double images/text? Operator Error? There used to be a tab to preview before I post? What happened? Can you increase the amount of time you have to edit a post? Thanks for all that you do!!!

I owe y'all for the off topic pics. By bad, Olga is from xxxxxx, in the sanskrit pants. Ella (RIP), is from Ukraine, in the blue. Master class w/ Doug Swenson. Ella's core is the only core from Ukraine that should be exposed. Ella & J helping me with my stiff ... back. Master class w/ Brian Kest. Going away luncheon. My yoga friends are my best friends. The manager kept bringing me drinks. #1 all time, any where, in all my born days. Peak yoga for me, age 54, 2010. Trail Ridge Road, Mountain National Park, Colorado, elevation 12,000+ ft, above the tree line. I was the only tree standing during a lightning snow storm. Had this part of the Park to myself. This is my Karma. Namaste, and Slava Ukraini!

Well, today was like a punch in the gut. After not being here for most of the past few days, I did my speed read last night/this morning to get halfway caught up. Thinking the Russia implosion (the word of the week) was in progress, I fired off my reunion post. Apologies. I should have read a few more pages. So, does Lukashenko come back to Belarus, or does Pringles bring his army with him and rule, or what?

They became my favorite people last year, but only because of my own ignorance. The clues were there, I just didn't bother to connect the dots. Chernobyl, and how so many Ukrainians were screwed at every level by the Soviet Union. Seeing the Antonov 225 (Mryia), along with the Ukraine Blue SU-27 escorts at OKC in 1990. Sevastopol being so prominent in every Clancy-ish military/spy novel I read. Olga, my yoga teacher from Ukraine. Crimea; (i) just cause I like the way it sounds, (ii) when i learned Moscow was 400 miles north of North Dakota (no wonder they're always pissed off), and (iii) 2014, I was so pissed that all the US did was hold our breath until we turned blue. The way the Ukraine people represent, in every way, in every situation, over and over. Dmytro Kuleba: Ukraine has one crucial factor on its side: "Historically, Ukraine was unfairly under-appreciated, and I regret it took a bloodshed and a devastating war for the world to realize how cool we are. And we will always be cool. But it just took you too much time to realize that." They became my favorite people last year, but only because of my own ignorance.

I'm calling this on myself ... Came in last night, 20+ pages behind here, and haven't looked at Titan since Friday night. This year, I took the steering wheel on our Family Reunion, a celebration of a Land Grant family from the Crown of Spain in the 1750's. Yesterday, the 2023 Edition, 300+ relatives, 20 briskets & 150 lbs of Elgin Sausage. Nailed it, with the guidance and effort of a lot of people. Happy for my 93 year old mother, and her siblings and cousins. Proud of our long history of Service & Family. For me, Volodymyr Zelensky has surpassed Winston Churchill as my favorite human in history; for the way he led us, not just the US us, but the entire free world us, by standing up to aggression and fighting, against the odds. He is by no means the first, but damn if his 'nads don't get bigger every time you see him. Agree 100%. This board know's it. The world will realize it in the months ands years to come. The ripples will reach far and wide, and for a long time. Gotta give Ol' Joe President Biden a ton of credit. He showed his Leadership of the Free World by herding a bunch of misguided cats (Dem's & Rep's) and got them to agree to turn the ship in the right direction. Starting with simply sharing information with everybody, allowing each of them to make their own judgements about right and wrong. Who woulda thunk that being open and honest might work? “Thank you for coming,” - Zelensky “More importantly, how are the children?” - Biden The humanity of Joe Biden, resonates with every decent man, woman & child in the world. Witnessing the compilation of karma and Darwinism and Fuck Around & Find Out displayed by Russia and Titan, and the Surly catalyst of unharnessing the collective knowledge, understanding, insight and humor of the many contributors, is the most rewarding and enjoyable reading of my not so young life. Well done. TLDR My Grandmother's family, one of 8 families at the reunion. Mom w/ the long white hair in the middle.

The ideal gas law ... is the equation of state of a hypothetical ideal gas. I know, ... no math. PV=nRT, where P, V & T, the variables, are the Pressure, Volume and Temperature respectively, and the "n" and "R" are constants, (PV=T); So, if the volume is fixed, for any increase in pressure there will be a proportional increase in temperature. Basically, if the pressure increases from atmospheric pressure (14.7 #/in2) to ~ 6,000 #/in2, there is a 400+ fold increase in pressure, which results in a proportional increase in temperature, the "heat of compression." Spoiler. Don't read any more. Eyeballing the pictures, the volume of air in the capsule would compress from the actual internal space to a volume a little bigger than a 5 gallon bucket. Envision a syringe the size of the capsule being instantaneously injected into a 5 gallon bucket, and in the process momentarily jumping to ~ 4,000 ° F (???), ... or, don't.

"CAPCOM - GOLD - Ah, yeah, Jim. Could you check your CO2 gauge for us? JIM LOVELL - Yeah, Houston. We were just looking at that. Our CO2 measurement has jumped four notches in the last hour. FRED HAISE - That can't be right. I went over those numbers three times. CAPCOM - GOLD - Jim, that sounds about right. We were expecting that. JIM LOVELL - Well, that's very comforting to know, Houston. What do we do about it? CAPCOM - GOLD - Jim, we're working on a procedure down here for you... Do you copy? FRED HAISE - Oh, Christ. JIM LOVELL - All right, Houston. We're standing by for those procedures. FRED HAISE - Christ, I know why my numbers are wrong. I only figured it for two people. JACK SWIGERT - Maybe I should just hold my breath." Seems like I read that the 96 hours was for 4 people. There are 5 lucky winners today.

Nothing but red flags for me... Did they bring extra AAA batteries for the controller? The pressure at a 13,000 ft water depth is ~ 5,800 PSI (pounds per square inch); Not unlike an F150 pickup balanced on your big toe. A pressure hull made from 2 dissimilar materials, carbon-fiber and titanium, that expands/contracts w/ pressure & temperature changes, at different rates, and that are mechanically joined together by a third material. Why the Titan wasn't safety classed? Marlene Lenthang The missing submersible Titan wasn’t classed by an independent group that sets safety standards, as most chartered vessels are. OceanGate said in a blog post in February 2019 that Titan wasn’t classed because its technology was so new and their innovation “falls outside of the existing industry paradigm.” It said there’d be a “multi-year approval cycle due to a lack of pre-existing standards.” Classing usually checks if vessels meet standards in buoyancy, number of life rafts and hull materials, the blog post said. OceanGate said that while classing has a safety value, it is “not sufficient to ensure safety.” On other words, "... we're going to do something that's never been done before, so it doesn't have to meet any kind of existing safety standards ..."

Hondo, I "responded" to your post, but my comments were not directed at you. Apologies. I read about 5 pages of comments before yours, and with my alcohol induced wisdom, let it fly ... So, a 60+ year old man kicks you in the ass, and you go to jail for doing something about it? The more I think about it, the more I like it. Ok, sorry. Still, someone ragging on DC & EK? They didn't make an error or a bad decision that led to a "hit", they never saw the ball. They're kids playing a game. EK has 40+ career infield hits and has patrolled CF as well as anybody, and DC had as complete a year as any player I've seen in almost 50 years. It clearly was not our destiny to win. Nuff said? I agree you need hitting, timely hitting. But Pitching & Defense still rule. Quinn Matthews made a good hitting Texas team look really bad. LBJ made Miami look bad. A pitcher can get in a groove and control a game like nobody else. Some aspects of the game change. Aaron Judge puts up big numbers, but Jose Altuve and Alex Bregman put trophies in the case. Knowing the Stanford pitcher hadn't pitched much this year, I expected our guys to take some pitches. Nope, went up their swinging. I'm sure Gus was cussing from his grave. I did notice, going into the conference tournaments, only 2 SEC team had winning records on the road, with 4 in the Big 12, including Texas. The SEC will be fun. Brutal, but a lot of good athlete's showing their stuff.
