Shameless plug: we're building a repairable e-bike battery where you can use your own cells at https://infinite-battery.com We worked on a very sturdy casing, with some specific features to release pressure and limit the fire event propagating cell to cell, you can check it here https://www.youtube.com/watch?v=v0NXXfCA2CY

I payed 1$ in July 2024 to reserve a launch-day discount. I never received any emails from Gouach after the receipt. You moved from Kickstarter to you own website. Are you actually shipping to costumers? I was super excited back then about your product and company, but the rebrandings and lack of communication made me wary.

Yes we are since a few months! Your email might have got lost? Please send us an email at contact@gouach.com with your details!

Are these rated? My local bike shop won't sell anything without that specific safety rating. I forgot the exact number. I've seen that more and more common lately

Yes! We have the EU certification and are undergoing the UL certification, it should be complete at the end of the year!

That’s pretty cool, but it took me quite a while on my phone to figure out what I need. Been doing e-bikes since 2007. Also, the little plus next to the shop was confusing to somebody that had a beer. I think your product is hot, thanks for making something that the world needs.

Thanks for your feedback! Would appreciate any tip you have in making the website more clear, please send us any feedback at contact@gouach.com !

Please also cite where he allegedly said that it's a doomsday event before you put up the strawman and debunk it with "look even this guy changed his mind" Edit: The only concrete thing I've found in trying to seek through your tedious video links for 10 minutes (idk why I'm spending my time on this but here we are) is the claim that, instead of living healthily, we'd be "constantly dealing with the human and financi…

Sorry, I didn’t double check indeed. I posted the wrong TED talk from him, see [1] at 4:21. There he says we need to limit climate change by limiting population growth. I think this is quite a hypocritical stance from someone who flies private jet all year. [1]: https://youtu.be/JaF-fq2Zn7I

New strawman! Now it's no longer "Gates changed his mind on it being an existential crisis" but "Gates wants population control"

The source again doesn't check out. He says:

- the formula at ~4:21: more people use more energy (I think that stands to reason)

- you hear laughter as he then says "one of these factors [in the formula] will have to get pretty near to zero". It seems exceedingly obvious to me that the next slide being about the people term of the formula is either a joke (and recognised as such by the other listeners) or a mistake about switching the slide too soon. If this is your evidence that Bill Gates wanted to solve climate by eradicating populations, it's going to need to be backed up somewhere else, preferably also by actions as he has put a lot of his money where his mouth is, that shouldn't be hard to find tangible evidence of

- 4:47 mentions how much we could reduce population growth by e.g. offering condoms and pills to people that otherwise don't have access to them, and by offering vaccinations to people that can't afford them (since better survival of parents causes lower birth rate)

As for whether it's hypocritical that he flies jets (to an unspecified amount), idk, if I could offset my emissions to negative a gigaton per year then I'd also feel like I'm doing my bit. It would still be better if he didn't fly, I can see how one calls him a hypocrite for that part and perhaps even agree, but in this context it seems like yet another angle to this argument seemingly designed to hate him no matter what he really says and does

If you have the space for it, just put it outdoors 5' from anything flammable and you're good to go. This is not a hobby for folks in apartments unfortunately. I've had one of my DIY ebike batteries short and fail spectacularly at near full charge and was able to push it with a broom out of the garage into the driveway before any damage was done. Now I have a bench with wheels that I can take into the driveway for in…

Sounds like it’s also not a hobby for people with neighbors.

At least not neighbors likely to be alarmed when their neighbors run out of their garage at odd hours of the night, pushing a flaming cart and screaming "fire!"...

Tiny standards in legislation (I'm looking at you EU) around the e-cig designs to ensure simple battery recycling would solve this. Then you make the consumer pay for the battery separately and you are done.

A simple deposit might fix this. Many countries already do this for glass bottles and cans. You get the money back when you return them for recycling.

Also could work for other e-waste (phones, tablets, etc.). For some goods like washing machines, this is already common. Extending that to other product categories might be doable.

It does put some additional work on shop owners that have to pay back those deposits and collect them. Which means additional bookkeeping and some mechanism that ensures they don't end up in the negative on deposits for goods bought in another shop. And of course the extra deposit means prices go up as well. Even if you get it back at the end of the product life, it is extra cost.

Vapes being thrown away casually on the street has a bigger underlying problem of littering not really having any consequences. Some people just dump their trash wherever and it's just considered normal (by them). Some big fines would be appropriate here in my view. It's negative behavior. It's easy to know when you are doing it wrong and pretty much inexcusable. The only reason people do this is that they are being sloppy and don't really care. If you are caught red handed dropping your trash where you shouldn't, it should have some consequences. I'm not a fan of the nanny state but this is an area where I wouldn't mind people being corrected quite a bit more than they currently are. I don't think this should be that controversial.

Several European countries already have disposable vape bans.

> Never ever consider doing something like this. Unless you're a hacker, and you like hacking on stuff, then by all means, read through all the warnings and please do consider doing similar to what OP did, it's a lot of fun and you'll learn a lot!

Eh, as a hacker who has wasted time on a lot of dumb stuff I would encourage people to not follow absolutely every obsession you have and think of the opportunity costs of new projects you take on.

As a hacker who never wasted a single minute of my life, yet did a lot of dumb stuff, I'd say your mindset is what's getting in your way, not the amount of dumb stuff you've done :)
