Plenty ( https://plenty.ag ) is trying to scale hydroponics using plant science and automation. (I worked here till a few months ago.) Indoor agriculture is going to supplement our nutrition needs in the future. Plenty is focusing on flavor as its selling point, and after eating Plenty produce, everything else seems like eating cardboard.
Why'd you leave--just curious?

I can agree that the view of whether something is helping or not could be subjective. That's not necessarily true about the infrastructure. The estimate I saw said if all the gas cars were replaced with electric ones then the infrastructure would have to double or triple depending on how much off-grid equipment is adopted. I know my house would need an upgraded connection to handle a 50amp charger. I'd probably need…
I was actually thinking about the long-distance transmission lines, but that's a good point about potentially needing to upgrade local lines. As a non-EV owner, I can't discuss much but I was under the impression that you could just plug in to a normal wall socket for a slow charge. I suspect that you're referring to the Level 2 quick charging station. If that's the case, that would certainly impact you depending on…
Good news is that we are nowhere close to the breaking point, but the numbers in the article are way less than if all (or even half of) cars were replaced with EVs. It should take a long time to get to that level of adoption anyways.
At least for me, I would want access to fast charging options, whether in homes or at dedicated stations for trips. The 8 hour charge is great for daily usage though. I wonder how that time can hold up as the range gets longer (increased capacity with same 15 amp wall plug).

Sort of, the runoff ends up in the ocean, which would be a global concern too.
Wouldn't that depend on how far inland the mine is? Certainly, mining operations tend to pollute groundwater, but I wouldn't expect that a mine that's more than a few miles inland would significantly pollute the ocean via runoff.
I don't know that I would use Telsa as an example. Sure, they are replacing fossil fuels with renewables, but I see this as trading one dirty commodity for another. Lithium mining is environmentally damaging and the impact will likely get worse as demand increases. So maybe a step in the right direction, but definitely not a true solution.
Fair. But I do think "better = good". It fits my main query of 1. Well funded 2. Trying to solve meaningful problems
Say you worked in a software development organization that was dysfunctional, shipped updates 3-4 times a year and had lots of infighting/political battles between teams. A vendor came by talking about a new development process with a cool tool touting amazing features - do you think buying into this process plus tool is going to solve your organizational problems? Is tech the right tool to attempt solving societal p…
My general guess is that anything actually worthwhile will have little to no private funding behind it.
Global heating. Racism. Soil extinction. Fascism. Disenfranchisement. Inequality. Female disempowerment. etc.
I guess there is government cheese for global heating. Not sure how much useful work would be done outside of government-run and/or -funded laboratories.
And anything that could potentially start out as being at least notionally-well-intentioned will come around to being not that.
My general thinking at this point is I have to find or help to create a small, well-organized group of people who start a not-funded social movement that will oppose almost everything most philanthropists and investors and do-gooders actually care about.

isn't this what governments ought to exist to do? "promote the General Welfare" is within the first 30 words of the Preamble.
Promote - as in cheerlead, facilitate, protect - not as in, well, try to do by forcing participation.

Tesla is actually a good example assuming that you believe that lithium mining is better than coal mining or at least an equivalent problem. Tesla's utility-level batteries (MegaPack) make wind and solar projects more economically feasible since any excess wind can be stored instead of being sold at negative rates when its not being used. These batteries will allow the replacement of many coal-powered generator plant…
It isn't a matter of belief - lithium mining hardly qualifies as mining environmentally compared to other methods including oil wells and ore mining of various methods. There is a lot of misinformation and FUD involving Lithium Mining. It involves brine pools in salt plains. Water usage is the only real concern. Not to be ignored but it won't leave any superfund sites, cancer hotspots, turn rivers dead but colorful w…
It's probably a step in the right direction, but I'm looking forward to supercapacitors or alternative battery tech.

At CIONIC, we're tackling how to overcome disability through precision bionics. Whether a diagnosis at birth (Cerebral Palsy, Spina Bifida) or an acquired disease or impairment (Parkinson's, issues resulting from a stroke), we're engineering sleek, wearable solutions that will provide comprehensive analysis and precise augmentation to enhance human performance, restore physical function and increase independence. Che…
This looks cool. Why do you think this hasn’t been done before?
