Random / Great book
« on: November 28, 2020, 10:13:12 PM »
This is one of those listen to it on audible, then read it, then listen. Lather, rinse, repeat kind of books.

Sean Carrol--the Big Picture. What a mind. I confess to getting a bit distracted when he runs on about the limits of theist arguments. I've always taken a weak (non-mathematical) Bayesian approach to trying to understand life, the universe, and everything--so I don't need much help with questions about god. I thought that was all bullshit from the time I was about ten--maybe younger. But everything else is pure gold.

Get it, listen to it or read it, be a more complete human being.

Random / Researchers say ADHD is a good thing. Wow, no shit...

I've just read three papers that kind of stunned me--like everyone who has it didn't already know that. Yes, folks get pissed at us when they discover we aren't doing what they wanted us to. Sorry about that. Probably what you wanted was boring. Pick it up a few levels and you have my complete attention...for a few minutes anyway.

As probably anyone who has spent more than ten minutes talking to me knows. I'm somewhere on the light end of the Asperger spectrum, and asshole deep in ADHD. I don't make funny noises or twitch, but if you want me to do something you need a bit of patience. I'll get it done, I always do, but the timeframe is not under my control, and certainly not under yours. Teachers don't like that. I flunked physics in my senior year of high school and won second place in the national science fair--in physics.

When I bump into a fellow "neurologically challenged" sufferer the communication is instant. Doesn't matter how old they are, what sex or race. We can talk--if we can get the words out fast enough.

So no, I have never considered it a handicap. It seems odd that someone does, but then someone is paying for this research. I get the need to understand a little more about the function of the human brain, but it still feels odd that people think a little Aspergers and ADHD are anything but a good thing--it's like someone feeling sorry for me for being tall. I'm not insulted, it's more like: What?!?

I went to Parris Lake today and leaped off this thing in every way possible. I actually did pretty well and got some long rides, but every ride but the last one ended with a giant splash. Note to self--wear the wet suit. I trunked it, and spent most of the drive back with the heater on full blast, melting the vinyl in the truck. WTF was I thinking???

I bought a lightly used Takuma/something efoil today. I was at SanO hanging with talldude, Capo, and cowboy when I got hold of the guy selling it and arranged to meet. That meant I had to leave to go pick it up, and the line to get back in looked to be at least an hour, so I went to Doheny.

So okay. this is going to take some time. First, these things are insanely heavy. With the battery in place it's a challenge to carry it. I lugged it to the water and was thrilled to be in a few inches of water so I could float it. If you release the dead man switch while you're moving the nose buries and I eject vigorously. I got to my feet fairly soon and was able to drive the thing around off the foil, then I gave it the boot and popped it up. Did a few porpoise moves, then buried the nose at speed and bounced off the water. I finally managed some long runs, this thing gets rolling very soon, very fast. My longest run was probably 150 yards and most times I crashed it was because my finger slipped off the dead man. When the motor stops the fun ends about a tenth of a microsecond later.

Still, not bad for the first time and I can see that this is going to be a lot of fun. One more thing to do in the water.

Sorry I disappeared guys, I would have come back but that line was ridiculous.

Model Y will be better if you can get one, but ultimately my surf vehicle (and everything vehicle) will be the cybertruck. They can't build that soon enough for me. It has everything I want in a vehicle, including the ability to load motorcycles without a separate ramp, lots of lockable storage, 4WD, 500 miles of range. monster inverter, compressor, and towing capacity. Not to mention stainless steel construction. A stainless steel surf rig? What could be better?

I met a very strange, very rich dude years ago who had two Ford F150's with most of the bodywork and all of the fasteners replaced with stainless steel. No idea what that cost him, but it must have been ridiculously expensive. He just didn't want his stuff to rust. His family owned most of Irvine, CA, so he could afford it, but the cybertruck will be much better.

That will certainly help. All these wings flex a lot which changes the aero aspects dynamically. In a lot of ways, it's remarkable that they are as stable as they currently are.

I've been wondering what was holding up Lithium battery recycling since it's obviously important and certainly a high potential margin operation. Lots of green money looking for someone to do it at scale. It turns out there has been a lot of investment and major projects underway, a bit under the radar.  JB Straubel, who was Tesla's CTO and a co-founder of the company, stepped down in 2019, and went off to found a company called Redwood, to do exactly that at a gigafactory scale. Interesting tech, and of course all the green funds are putting money into the venture. They've built two substantial recycling plants as a large-scale pilot that have a larger scale and broader reach than the recycling facility Tesla built in Nevada. I get the Evannex newsletter but somehow missed this one back in August.

It's an obvious way to close the loop on what will become a tidal wave of recyclable batteries over the coming decades. All the useful materials are present after use in many times the concentration with almost none of the waste material of refining from ore, regardless of the state of the battery. There are successful examples of closed loop manufacturing already--lead acid batteries are mostly made of recycled materials--99.3% of LA batteries are recycled and 80-90 percent of the lead and plastic in new batteries come from recycling. Lithium batteries have far more valuable constituents and should be nearly 100 percent recyclable including the shell and possibly the insulators. 

It's an absolutely necessary element of shifting to storage as a major piece of meeting energy requirements. And the money side is obvious, 50 to 75% of the cost of a battery now is materials. In the early days it was manufacturing labor and capex, now that's shifting quickly as highly automated manufacturing comes on line.

Heading to SBJ tmrw to pick up my Waydoo Patroller from a guy who used his twice, and decided he's just gonna stick to surf foiling.

Stoked to say the least, since I'm not only getting a good deal on it, but also don't have to wait till the end of December, beginning of January until their next container comes in, as was going to be the case to get the longer 31" mast I was looking for that they're currently sold out of.

EDIT: Pono, I'll be down at SanO Thursday (if I can sneak out on turkey day) and Friday with it if you want to give it a should have my cell# to text to confirm.

Cool, I'll plan on Friday for sure and probably try to come Thursday as well.

Dihedral provides stability by increasing lift on the low wing when a wing is tilted relative to the center of gravity. Lovely when you're flying level. How often does that happen with a foil wing? Never would be a good guess. Still, in many cases it makes the wing more stable, but if the righting movement shifts the center of gravity (which it does often with a foil wing) the righting effect changes and even reverses, so the wing hunts.

To see an example, hold the wing over your head and hang your weight steadily down--the wing is stable. Now tilt it a tiny bit and don't put as much weight on it. If the dihedral is working as it should it will wobble all over the place, "correcting" for CG that is constantly shifting as the wing wobbles.

The common fix is a little washout in the wingtips. Washout makes the wing stall at the root of the wing before the wingtips by reducing the incidence angle of the wingtip relative to the root but also stabilizes the wing as it wobbles around by reducing lift of the lower wingtip. But there is no complete cure, any time the CG can move around the dihedral will try to correct.

Oh, and Pono, I can get you test rides on Waydoo, Lift, and Flyte while you're in SD.

Cool. How and when. Have truck, will drive.

In my opinion, the biggest benefit of new toys, including SUP, is that you can use them at the places other surfers can't or don't, and my general rule is to take full advantage of that. In Maui I frequently violated that rule since SUP surfing at Kahana is simply so good, but even there I tried to find places that worked for me that weren't popular--which generally meant moving as far to surfer's right as the waves permit. Sometimes that just attracts other surfers though, once they see you getting waves, like surfing at Ho'okipa at Lanes--which I swear you'd rarely see a surfer even on crowded days until the SUP surfers started using it.

It's not some sort of moral position for me, I just don't like surfing with people who aren't my friends.

Foiling is 10x better for that than SUP. I'm never within 20 yards of a surfer--more like 100--even at SanO. the closest I get to anyone is the sit-down guys because they're looking for the same kind of waves we are and are relegated to the same stretch of crap surf--which is perfect.

I figure eFoils are 10x better than surf foiling for the same reason. No possible reason to be in a lineup. About the same level of solipsism that wingfoils offer. Wingfoiling has to be the perfect sport for loners like me. I'll get one sooner or later-probably later, though this year is a great excuse for getting one. As I'm typing this I'm wondering "what the fuck was I thinking?? I'm in the fucking desert, 2.5 hours from the beach. There are lakes. Why didn't I buy an efoil?"

What a moron. We move to Solano Beach in a week, so it probably doesn't make sense now, but I think my timeframe just jumped way ahead.

Hmmm, I should probably send Alan an email about that, though he'll figure it out quickly enough. I made a breakaway drogue leash years ago after being dragged underwater for a ridiculously long time by my F18 after I got tagged on a Maliko run. A light nylon drogue connected to the second leash plug pulled into a thin nylon sock (just a tube I made out of the drogue material). It was held parallel to the leash with rubber bands, with the sock connected to the leash. When the breakaway connector pops the leash is released and the sock got pulled off the drogue. I fiddled with it for a few weeks and gave up--too unreliable to be counted on, and in the surf all the drogue did was pull the board away backward at high speed.
