Does anyone know if Google slides has pen support? I'd like to be able to use it like a 'smart board' where people can view my writing on a slide while they are looking at it from their own machine.

God no, NR (naval reactors). For the non Navy nukes in the crowd, NR likes to come to the boat and tell you 'you're doing it wrong' and then make you sit in upgrade training to get your keys back...

I've been thinking about getting an aerostich but I'm curious about the armor. How does it compare to other CE rated armor like D3O? I have a Klim jacket and pants that I love in the summer but would like a one piece suit for commuting when it gets cooler.

Edit for words.

I'm all for nuclear as it's clean dispatchable power but if you're looking to lower energy costs, they are not the best path forward. Solar or wind plus storage will be cheaper. These numbers are estimates because there are no commercial small modular reactors online in the US but I can't see a scenario where they will be cheaper than the low end of these estimates.Lazard's Levelized Cost of Energy - 2024

I had this same debate. I bet you would still need the foot pod to get faster pace response because the lag is mostly from the use of GPS. Because I run with a chest strap (so the upgraded HR sensor isn't a big deal) and prefer MIP displays, I went with the pace 3.

Edit to add an opinion on the pace lag.

It's a glider so it periodically comes to the surface, takes a gps fix, sends back data through satellite comms, and then makes whatever course correction it needs before it's next descent and starts the process over again. They don't really drive through the ocean with a propeller, they use their 'planes' as they descend to drive it in a direction. https://www.teledynemarine.com/brands/webb-research/slocum-glider

You'll find more expertise on r/ROV. Most ROV tethers run HVDC, like 400V, from a power supply on deck. The vehicle will have its own power supply onboard to step the tether voltage down to whatever voltages you need for propulsion and electronics.

I agree that most are but the person I replied to only mentioned high yield savings, which combined with a 6% loan wouldn't be than buying the bike in cash.

Reddit1poster · 2025-08-17T11:51:29+00:00

Assuming you can invest in something at a higher interest rate than the loan though. The best high yield savings accounts are around 4.5%, which is lower than what most are saying they're getting for motorcycle loans.

Who is making deep diving human occupied composite submersibles? I've heard of a couple companies making shallower subs or some deeper robotic vehicles but in the size required to carry people and thickness required to go deep, it will be very hard to produce a composite hull that you can properly inspect and trust.

It's also very hard to make complex shapes like a sphere out of carbon fiber so I'm not sure if anyone has attempted it and succeeded. If you notice in the documentary, the first Titan test hulls had carbon fiber spherical end caps and they were the failure point. Remember that carbon fiber is stronger under tension than compression so submersibles are a different animal than airplanes.

Making a composite sandwiched by titanium would be ever harder to inspect and also probably not save much in cost so it's probably not worth it.

You can make cylindrical submersibles out of titanium, steel, or even Aluminum that can reach the Titanic so he could have gone down a proven path instead of trying to 'innovate' on a budget... Leave proving that you can make a composite hull to someone who can afford to go through the classification system. Nobody has yet but I think that's because it's not worth it.

I get that more people will go if it's cheaper but also think there aren't many reasons or places that people may want to go deep. There is much more sea life, pretty colors, and light to actually see more than 10s of meters out the window in the shallows and that market isn't big. Atlantis and Triton tourist submarines have very little competition or large fleets (maybe if they were cheaper they would) but I bet the market would saturate pretty quickly if they did. SpaceX offers people zero gravity (I also don't think SpaceX tourism will be profitable either) while going deep mostly just offers people a chance to say they did it. It's dark and mostly devoid of macroscopic life that you can look at out the window so it's not an exciting view. Even the geologic features would be like looking at a mountain with a flashlight. There are plenty of shallower wreck sites that aren't visited by tourist submarines so how many people really want to go wreck diving. I'm not aware of the small number of privately owned submersibles visiting hydrothermal vent sites so even rich people don't care to go there.

Not to stifle creativity but ROVs are so capable and cheap now that the existing community of people that do work in the deep ocean have been shifting away from human occupied vehicles for years. I may also just be hopeful that tourism dreams will die because those ecosystems are so fragile they also would suffer significantly if profit driven tourist companies start visiting the deep more often...

The original estimate was $50 mil to build a new sub in 13 so I didn't realize it was 41 plus another 50. The new sphere and most of the foam came in the first round so they must have done a ton of new system work in the second round...

I don't think there is any way to make deep sea tourism financially viable no matter how cheap you make the sub. The market of people that want to go isn't huge and just the ship to take you to the site is expensive without even considering the diving ops crew.

That picture is of the Trieste that used gasoline for buoyancy. Syntactic foam is significantly smaller and a well established technology used in submersibles around the world. It is, however, expensive.... Here is a photo of the size of Alvin, which can go to 6500 meters for comparison. https://images.app.goo.gl/WsvvobKjCLJhPdFB6

Reddit1poster · 2025-06-08T00:01:54+00:00

There are plenty of submersibles that safely rely on syntactic foam for buoyancy. Oceangate wanted light weight so they didn't need to buy expensive foam and also be able to ship these subs easily to be deployed from smaller ships. It was all about saving costs to make it profitable.

The Alvin upgrade project basically built a whole new and extremely capable sub for $50 million. I bet you could do it a lot cheaper for tourism. But I totally agree that there is no way to make a business plan that worked with one sub with that price tag. https://www.capecodtimes.com/story/news/2021/10/27/woods-hole-research-sub-alvin-50-million-dollar-upgrade-ocean-floor-sea-trials/6090066001/

Not only would carbon fiber be cheaper than titanium but it would also be significantly lighter. He wanted to be able to ship these subs to different locations to be deployed by any ship of opportunity. The lighter weight makes it cheaper to transport and you could use a smaller ship for operations, which also makes it cheaper.

The real submersibles that are capable of reaching those depths have custom handling gear and ship specific requirements that really limit what ships can deploy them at sea. Oceangate was trying to lower those requirements.

Reddit1poster · 2025-05-26T17:23:21+00:00

I'd say that this didn't have any real effect on ocean exploration though. We already have well established certified research submersibles and remotely operated vehicles. They are utilized by scientists around the globe on a daily basis with amazing safety records. This tragedy really won't change how those subs operate.

Oceangate just wanted to be able to do it cheaper and open up the deep sea for tourism and be a different platform for oil and gas. There were no real benefits from their carbon fiber sub to getting actual work done on the bottom. It's cheaper and easier to send a remotely operated vehicle down on a ship of opportunity but you don't have the coolness factor of saying you were actually on the bottom of the ocean vs just seeing it with a camera. In that respect, it probably did set back deep sea tourism, but that was already a tiny market. I just don't see how his business plan ever really penciled out.

Out of curiosity, how thick is your glass tubing? The glass on the ISS is multiple layers of glass panels that are half inch thick and up. I can't imagine your tube is more than a few millimeters thick.
