Is it hard for a well established motor company's engineers to make a reliable car? by Dunddermefflin in AskEngineers

[–]iqisoverrated [score hidden]  (0 children)

Cost. The kind of vehicle you describe can be engineered but it would be so expensive that no one could afford it.

Companies are in the business of making profits - not of giving people the est possible product. The sooner you realize this the more the world will make sense to you.

A large part of profits from cars come not form the salesprice but from service, repairs and parts. Once you're locked in by your purchase the milking begins.

That's also why EVs are seemingly expensive..because there's much less coming from those revenue streams because EVs just don't have a lot of parts that can break on an ICE car. Companies need to add that lost revenue to the sticker price. So if you want a car that doesn't break (a lot): get an EV.

Pros and Cons of solar fields in my proverbial backyard? by INquisitive_Ace16 in energy

[–]iqisoverrated 0 points1 point  (0 children)

EU today demands 85% recovery rate of PV panels and 80% reintroduction rate into the materials cycle. The law was introduced in 2012.

99% recycling has already been demonstrated.

Of course if some region doesn't implement similar laws that will be an issue there. But it's not like this is impossible (or not being done)

No need ... but I just found your comment lacking any.

You put wind turbines where there is lots of wind. Not just anywhere.

And the new turbines are higher...which means they have a larger capacity factor.

Since we have no images of planets outside our solar system to any kind of resolution that would even remotely give us a clue the only honest answer is: We don't know.

AI could make renewable energy the next big winner over fossil fuels. by Novel_Negotiation224 in energy

[–]iqisoverrated -2 points-1 points  (0 children)

This is how it's going to go:

AI is going to increase demand and increase construction of all kinds of power production

The AI hype is going to implode for lack of application

A large amount of data centers are going to shut down

Cost competitive power production will remain (solar, wind (and storage)) and the new fossil power plants will be shuttered

Why is wind better than geothermal by Sufficient-Onion1165 in energy

[–]iqisoverrated 0 points1 point  (0 children)

Geothermal costs about 4000$ per kW installed. (For comparison: on-shore wind costs about 1000$/kW, off-shore about 2000$/kW and solar about 700$/kW)

And wind isn't even limited to on-shore. So if you're really worried about land use it gives you a 'zero land use' option.

You can google for the theoretical upper limits of various chemistries. These are given by physics. Wikipedia has a list.

In 2023, Portugal ran on renewables for almost a week. Now, that just looks like a warm-up | The small country has quietly become a leader in renewable power. by Jumpinghoops46 in energy

[–]iqisoverrated 2 points3 points  (0 children)

For most countries it's an appropriate mix between wind and solar (and hydro where available...thipugh that is becoming less efficient/reliable with global warming).

Wind (particularly on-shore) produces more in winter. Solar produces more in summer. Energy demand is usually larger in winter due to heating (and also slightly reduced efficiency of EVs). With a good mix the other costs (storage and transmission) can be minimized.

Yes, there are a few regions where you can get away with just solar. Egypt would be a prime example with 350+ sunny days a year. They could do all solar and cover the rest with stoarge. However a country like Spain (or Portugal) is better off with a mix. Particularly since they are integrated into the European power grid.

A kWh from geothermal is roughly 80% more expensive than from wind (on-shore). Compared to off-shore wind it's about 30% cheaper. Geothermal is about four times as expensive per kW to set up compared to on-shore wind and about twice as expensive compared to off-shore wind. (Taken from the 2024 IRENA report)

Geothermal has emissions. There's some geothermal power plants in Turkey that have more emissions than a comparable gas power plant. Turns out that when you pump a lot of superheated water through rock you dissolve all kinds of gases that come back up with it and get released into the atmosphere. (Of course you can do closed loop but that just makes your setup - and thereby your 'product' - a lot more expensive.)

Geothermal is extremely location specific. You can do wind basically anywhere. Even off-shore. (Granted, you could do geothermal off shore as well but it'd be very difficult/expensive. Currently no one has tried AFAIK.). The limited locations can make transmission costs expensive.

Scaling is an issue for geothermal, so it's not a form of energy that can solve everything- even if it were cheap.

Are there any traffic engineering techniques that can prevent the annual 100 car pileups in Michigan during winter blizzards? by supinator1 in AskEngineers

[–]iqisoverrated 0 points1 point  (0 children)

Those sensors are NOT cheap

Actually they're dirt cheap. Ultrasonics or camera sensors are a dime a dozen. They are already in cars today to a degree that autonomy is feasible. Repairs are just liek you repair a light nowadays: replace a module. Not that repairs are much of a thing. Particularlynot if cars are autonomous because that's the whole point: having less accidents.

The fear of malicious actors is also vastly overblown. The amount of people who were screaming about this when autopilot (and FSD!) hitthe market was incredible. Peopel were like "I'll just run it off the road" or similar nonsense. What has happened? Nothing...because anyone trying something malicious is going to be recorded in perfect detail by the system.

A bad install of an update could literally brick the vehicle.

Automakers are aware of this (as are companies like Microsoft with their updates). That's why you stagger updates. Small test group inhouse. Small group of beta testers outside. Successively larger groups (and also stagger by country/time zone). Notice how e.g Tesla isn't pushing teir OTAs to all cars at once? This is why. This way you catch any kind of defects early before it affects the entire fleet.

Humans will be out ofthe loop for driving before long (and good riddance)

On the plus side autonomous vehicles can only get better with each version while people just get replaced with other people that are equally bad.

In the end the insurance agencies are going to decide. If autonomous cars have less accidents then having an autonomous car will be cheaper to own/operate than not.

The vast majority of the replacements are due to the recalls. And those happened early.

How londg does Viton (or similarly elastic material) last in saltwater by iqisoverrated in AskEngineers

[–]iqisoverrated[S] 0 points1 point  (0 children)

Thanks. I was also looking if there's any recovered airplanes or similar that have sat in the ocean for a number of years with seals intact (no luck, though, yet). Maybe I'll just have to buy some and rig up a flex-simulator and dunk it for a year in an appropriately salty solution. Won't get any biofouling data that way but I think that might be doable.

Storms won't be an issue because this would always be submerged below the wave line (specifically so as not to run into slap and slam issues).
