Varies widely across country and the type of thing you're recycling. People are so extreme with recycling, it's either "recycle everything!" or "it's a scam, just chuck it all in the garbage"
I’m relatively sure that electronics are not recycled properly anywhere. At best some of the metals are extracted (hopefully not by mixing the ashes with mercury).

Regular trash is already stored safely.
The great pacific garbage patch disagrees.
I'll assume good faith here and that you were simply unaware of the origins of the so-called great garbage patch, but in future discussions I think it would do your arguments some credence not to bring up ocean plastics in response to discussion about landfills.

People have been stealing and killing other people as many years if not longer. That doesn't mean you cannot do a bit of legislation and obtain some positive results against that. I think not banning the cigarette and non reusable vape is the wrong solution but banning smoking in lots of public spaces has improved the situation, maybe not to curb consumption but at least non smokers can breath a little. I wish it wou…
> People have been stealing and killing other people as many years if not longer. That doesn't mean you cannot do a bit of legislation and obtain some positive results against that. This thread is/was about prohibition of smoking. I was making the point that tobacco/nicotine is a drug that has positive psychoactive effects, that's why people use it. People seem to have this misconception that smoking is just some thi…
I was suprised to see recently that ban on smoking is still not enforced in some bars/club playing music in Germany. It was like a blast from the past to me after living in countries that implemented that strict ban much more seriously for years.

If you believe Lumafield, 8% of low-quality lithium ion batteries have a mechanical defect that can sometimes lead to a short circuit. Is this person really brave, or just unaware of the risks? https://www.lumafield.com/article/finding-hidden-risks-in-th...
He put a fuse on every individual cell and on the overall unit, so I would say he was reasonably cautious (although he deployed a bunch of high-voltage exposed wires at the end of the video, but we can assume that was just a tech demo).
This shouldn't be surprising since a vape is a safety critical device. Primarily because the temperature control has to be precise and you have to solve a surprisingly large number of control problems that can arise in real life. For instance, if you overshoot the temperature the amount of toxic by-products can increase sharply. You can also cause parts of the vape to disintegrate, and then aspirate things you really…

Tax CEOs of vape companies the percentage of their vapes that their company doesn't physically retrieve from customers to be recycled ...
A completely ridiculous and nonsensical proposal I can only assume was said in jest.

How close are we to smart dust I wonder? How small can we make wireless communications?
> How close are we to smart dust I wonder? How small can we make wireless communications? There's two limiting factors for 'smart dust': power (batteries are the majority weight and volume of this vape), and antennae (minimum size determined by wavelength of carrier wave). I believe you can fit an NFC module in a 5x5mm package, but that does externalize the power supply.
RFID is historically powered by one of three methods,
one of which is completely wireless/battery-free.
For these devices the microcontroller needs to be super cheap. Microcontrollers like the Puya PY32 Series (e.g., PY32C642, PY32F002/F030) can cost in the $0.02 - $0.05 range for the kind of many-million volumes applicable for disposable vapes. These are 32-bit ARM Cortex M0 MCUs, running at a 24 MHz clock or similar, some with 24 KB of ROM and maybe 3 KB of RAM! To put into context: this is 3x the ROM/RAM of the ZX81…
Which is why when folks nowadays say "you cannot use XYZ for embedded", given what most embedded systems look like, and what many of us used to code on 8 and 16 bit home computers, I can only assert they have no idea how powerful modern embedded systems have become. Now that it is a pity that when people talk about saving the planet everyone keeps rushing to dispoable electronics, what serves me to go by bycicle to w…
Bicycling, transit usage, and switching to lower-carbon food sources significantly reduces your CO2 footprint. Your example influences others in your community, though it may not be personally apparent.
