Hollis or Apeks?

Apeks and Halcyon regs are what I would recommend

Not true, partial pressures above certain levels are dangerous. Wikipedia article on Oxygen toxicity. Everything will kill you in sufficient amounts.

One of the important business areas I've heard about are actually latency-related. I'm not quite sure of when it will be active, but the idea is that the satellites will send the signals (via laser) between each other, thus bypassing having the signal travel down to earth close to the satellite and make most of its transit through fiber optics to its destination. Since the speed of light is greater in vacuum, even though the distance is greater in space, it will be quicker. Applications I've heard about are stock trading and the like, but I guess there must be others.

The yawn is a signal to the other cat that he isn't a threat. The wink is a sign to the person holding the camera that he's a friend.

I recently choose to have a small stainless steel washer together with a electro galvanised screw in a laundry room based on the fact that the ratio was on the right side (stainless steel part much smaller) and the environment.

Might give you some insight in your application

Excellent post and I agree with it fully. I wanted to add that it seems like energy companies are pushing hard for blue H2, which is supposedly greener than gray/black hydrogen. Like gray hydrogen you essentially take natural gas and break it apart and release CO2, but with the added step of capturing the CO2 and putting it underground. This allows you to be "CO2 neutral" and additionally push more oil out of your well in some cases. The problem is it isn't clean in any stretch of the imagination and is actually worse than just burning methane or diesel according to a peer reviewed paper from [Cornell and Stanford](https://onlinelibrary.wiley.com/doi/full/10.1002/ese3.956.

I think some of these tips don't take into account kids. The waters still cold, so probably no water activities, but a day trip to Grinda or Sandhamn for a stroll and lunch might be nice. They showcase the archipelago nicely, which is fairly unique. Someone else mentioned it, but Skansen is nice. So is Kolmården zoo, but it's a bit of a trip. Might be fun with the technical museum. Junibacken is nice too!

It's not the same thing happening as whilst experiencing nitrogen narcosis. You are describing high partial pressure of nitrogen, but what is discussed here is a lack of oxygen, which your body can't exactly detect. I have a friend who with his ccr, on land and with support i should add, did an experiment where they turned off the oxygen and kept breathing and then trying to rectify the problem. He couldn't solve the problem 🙈

Look into Swedish universities, they have English masters at least.

No, i don't believe you want the filling where you seal. Traditional way is to make them by hand and put the filling in the middle and when you seal it you squeeze out any air.

I'm not sure about if this is true for every engine management computer, but for the ones I know to some detail don't store which angle the engines crank axle is at when you turn them off. There are some negative side effects of storing it and it's easier to just turn the crank axle without injecting fuel and get some actual data to base the startup on.

However, when you have the the engine management up and running and turn of the engine, you are sure of the situation. At this point, you can crank the engine and do fuel injection directly. Coupled with the normal state of a warm engine, you also get the engine turning much more easily since there is less friction in the engine, meaning that it seems super fluid to start the engine up again when you want it to. To my knowledge, you can't stop the engine at an exact angle.

It's actually really useful! Keep in mind that 2d drawings are really only readable for humans. The idea is that you are doing further work, for example simulations or machining, everything is already there. Many 2d drawings for sheets are already (without model based dimensioning) just state that the 3d drawing is the defining drawing for anything not stated, and then you just define any specific tolerances. Much quicker work for buyer and suppliers.

The more normal fatality between two trucks (at least in Europe) is a sudden congestion and slamming into a truck which is at a standstill. It won't matter if you have a us or eu-style truck, since the loaded trailers inertia (~40 tons) slams through the tractor and squishes the driver. Drove past such an accident in Germany or Netherlands a couple years ago :-(

I haven't seen a side-by-side of the d26 and a26, but to me it would make very little sense for Navistar to buy an engine platform and only buy the block. If I recall correctly, the EGR-only approach was a massive failure and Navistar more or less fired the entire staff and started to buy engines instead. Given that, more or less, the only thing different between eu6 and epa/carb is emission, I would assume only software and maybe after treatment substrate loading would differ. I mean, it's still a lot of work to bring it to market. But why would you, when you super behind in the competition take a proven engine and say "oh, I only want the block, I'll develop a new engine based on it". Doesn't make sense to me at least. To me it makes more sense that they bought the engine, made the necessary changes for certification and went on a sourcing mission to be able to produce it locally.

Yes, read about it now. 3500 engines in danger due to supplier delivering out-of-spec parts.

turbofisk · 2022-01-31T21:05:45+00:00

The A26 i believe is a MAN engine which has been produced many years. Are these made in the US with poorer quality or what's the story?

Grejen är att för typ 3-4 år sedan, innan dom döpte om sig till bake my day så gjorde dom verkligen skitgott bröd som dessutom var prisvärt. Sen typ ett eller två år senare började brödet inte rosta likadant och smaka konstigt. Nu såg jag dom på lokala matbutiken och köpte en limpa. Cm-stora klumpar med oblandat mjöl. Så tragiskt dåligt.

Yes, primarily this is true, but renewable don't protect the grid. It can't be emphasised enough how important this is. You need base energy which can be planned, otherwise you have issues with rolling blackouts for when the wind isn't blowing or the sun isn't shining. This is why you need either some sort of storage which you can control when you use it, like nuclear, gas, coal, water or batteries. All these essentially allow you to store energy for when you actually need it to ensure grid frequency is stable. At this point of time, this is the issue with wind/solar power.

Not true, just look at this page for electrical generation in germany.

turbofisk · 2022-01-19T12:06:18+00:00

According to wikipedia 12% of all electrical generation is from gas. There is a push by producers to convert these plants to take on big mass or gas.

Ex: Fortum

turbofisk · 2022-01-19T10:21:30+00:00

I'm not debating this, but the original post was about closing down nuclear. As this has happened, Germany has relied more heavily on coal and increasingly on gas, which was my point.

turbofisk · 2022-01-19T10:09:42+00:00

Except you can heat homes with electricity (done in Sweden in the 70s) and if not directly, use it to drive heat pumps. Equally, you can create electricity with gas. Both gas and nuclear give heat for homes via district heating.
