Comment Have you ever seen a car shredder? (Score 1) 98

The problem is, it's going to take a number of years before EV batteries actually need recycling. Even after 10 years, many are still good enough for EV use. And after that, they are often useful in other places like home power storage or grid batteries. And this isn't recycling the cells, this is reusing the cells - taking the cells out of an EV and putting them into use in another application directly. So it might be 20 to 30 years before enough volume of EV batteries are scrapped.

There are already several companies that want to scale up their recycling, but they just don't have enough used batteries to scale.

Heck, even when an EV is written off and scrapped, the battery is often snapped up as it's still valuable - even damaged people extract and use the cells for other purposes, or rebuilding EV batteries.

So yeah, here's part of the issue. Car shredders. Crushed cars don't just get dumped into big pits of molten steel, crushed cars get shredded with large high speed hammermills and the component materials - iron/steel, aluminum - get separated out by magnetic and eddy current separators. The rest is called Auto Shredder Residue and ends up landfilled. It's all the copper and the materials that used to be glass and plastic dashboards and o-rings in Macpherson struts and stuff like that.

If you haven't seen ASR, it's a relatively fine grain, probably mostly under 0.5", and with modern cars, it's mostly plastic.

If you drop a Tesla into a car shredder (the eventual fate of most cars), I think the batteries will end up as ASR. And then you're trying to separate cobalt battery components from the old stuffed toys left in the back seat.

How do we shred this better, and why are we not already doing this with municipal waste? Hammermills have windage losses and crazy internal wear. Low veolcity high torque machines need even worse maintenance. Robots to disassemble cars seems like a good idea, until you've actually worked in an automotive wrecking yard and seen that cars often no longer look like cars....

There's a world of difference between sheets of drywall attached to a frame with fasteners and a stack of drywall on pallets.

As far as composite woods, almost all new construction is done with at least some LVL or similar lumber products, it's stronger, cheaper, and more uniform than the fast growing pines that are otherwise used.

Manufactured homes have historically been real low end products, fortunately today there are companies out there making better products, I remember watching a this old house episode post-Sandy about a lady in NY or NJ who had her replacement home brought in as a manufactured home and it seemed to be at least as good as your average home builders workmanship and probably most importantly it didn't look like a double wide.

Interesting, despite what TFA says this is what I get on your results:
Amazon Basics "Featured from our brands"
Energizer "Sponsored"
So, not only do they have the right to move products around just like every other retailer on the planet, but they're actually transparent when they do so unlike say Walmart where you get zero explanation for why something is on and endcap, at eye level for the intended buyer, etc.

You might not be aware of this but cars now implement Carplay and Android Auto over WiFi Direct to transport video, audio, touch information, etc.Because of this the implementation of WiFi protocol, WiFi Direct, and Android Auto/Carplay protocols matters to people who want to use those features.

Nope, there's no monthly fee for basic functionality, you can pay for full remote admin (vs dashboarding which is free) and for a protection service which does cloud backups and includes a device replacement service. Neither of those are required, the monthly fee goes to offset their costs for running servers in AWS or whatever cloud they are on and to provide a recurring revenue source plus it's a hardware replacement plan. Personally I've had zero reason to pay for either service, though with the zwave migration service of the protect offering I might do that in the future if my setup becomes complex enough (right now it's 3 zwave devices, so definitely NOT worth the fee).

Um, they did a paper after the Tesla semi was announced and redid their calculations based on the .35Cd that Musk mentioned, suddenly cost was the primary barrier, with a target of $150/kWh for the pack (something Tesla has already achieved based on estimates derived from model differences).

Musk has said recently that the 300 mile semi will have a 500kWh pack, based on the 167.7Wh/kg of the Model 3 that puts the pack weight at ~3.3 tons, the fuel tanks on a typical semi are about that when fueled. Even if you double that pack weight for the 500 mile semi you're still in the same range as the drivetrain with fuel for a long haul semi, I wouldn't expect significant cargo penalties vs traditional tractors.

I get protecting trade secrets and preventing working with existing or prospective clients

Except non-competes don't accomplish either of those. The first is covered by an NDA and the second is covered by a non-solicitation agreement. I will gladly sign either of those if they are correctly crafted, but I will never again sign a non-compete unless it covers 100% of my salary and benefits for the duration of the agreement. Having been screwed by an overly broad agreement and a petty former boss once I will never put myself or my family in that kind of risk.

It's not that I don't expect politicians to be swayed by big corporations, it's just the fact that they're so cheap to buy that bothers me. I mean you're representing several hundred thousand to 10's of millions of people, you should cost more than a couple thousand dollars of schmoozing to have your vote swayed.

There we go. Heavy water, the ultimate in pricey bottled water.

Move over, Perrier. This one's got kick!

It's neat that we can taste the difference, and if bottled water suppliers can mass produce it as a beverage it will surely reduce the operating costs of some types of nuclear reactors.
