It is very simple: the big corporation that made them, owns them. They have the scale and tech to do decent refurbishment and/or recycling. It is simply done and ~swapping batteries is much faster than charging them. Standards exist and are used for scooters.

Cardboard is great! i use it to keep the weeds down, as it composts. Amazon's is much better ... any other box requires a very laborious removal of plastics and metals.

Good design may not have made up for the "wealth inequality" aspect of ancient bike production ... but it could have surmounted the issue of bad roads: The Rungu 3-wheeled electric bike seems to be well suited to rough, off road, conditions:

i get around the almost ubiquitous usage of the "more" page design by: 1) going to end of page (END button) 2) clicking 3) repeat until there is no more mores

i only have to move mouse once, as the END button scrolls to the next more at the same spot. Thus it is a rote typing on two alternate keys repeatedly.

It would be nice if there were a JS button doing all automatically.

Great review! Yes both the review and the recent article i cited mention the use of hot and/or/both cold sources to boost efficiency. with high grades of both one can approach 100% Even low grade (AKA heat pump type) sources boost well.

Much simpler would be join the scooter scheme of ~swappable rechargeable batteries ... a ready made standard that could then work for any vehicle up to a car

By forcing ownership of batteries outside of consumers effective recycling could be much more effective too. Right now there is a huge cost, almost a planned obsolescence, when a EV's battery degrades ... as is inevitable with current tech.

Much better than batteries or gravity storage mechanisms is liquid air storage. It is not for small scale sites, but the bigger, the more economical, it becomes. As an OTS (off the shelf) solution i do not know why it is not used more...

Liquid air storage offers cheapest route to 24 hour wind and solar

Genesis is but one example of an oral folklore. All cultures had them (before writing ... which invented forgetting, ref Socrates). i would not at all be surprised if their cladogram is pushed back in time to when we shared the earth with other Homo species

If they could get over their proprietary dreams and just ~swap, instead of charge, the batteries it would be a lot faster for the users, would shift the recycling to entities that can do the job AND almost instantly build the needed infrastructure...

Well to increase safety one can use a fuel like ~methanol with a regular ICE, no need for electric conversion or reformation, just a new carburetor! i was suggesting NH3 because it is much more dense and involves NO carbon at all. Like i said farmers regularly deal with NH3 ... so it can be safely handled.

Those languages where the tensor/array is the fundamental unit: such as the APL family. J and K have optimized builds using AVX.

Haha, not so bad as loss of H2 containment (as seen IRL in Norway) ... and of course farmers deal with it every day.

How 'bout Ammonia fuel cells?

i would still like to know what "controlled experiments" exist. Has anyone done the studies to show it is not worth the while, eg that it does not remove carbon? Although just not removing carbon does not say seeding is not beneficial, carbon neutral aqua culture would be quite beneficial.

There are some natural experiments: the Sahara feeds the Amazon, and the Gobi feeds the Pacific ... Perhaps more directed seeding would be more beneficial. We will never know unless we actually study, or try.

i would be interested in what/where those "controlled experiments" were... my understanding is that even experimenting is a no no in the field of geoengineering. Versus reflective schemes this actually "removes" carbon and is thus is a net gain, not merely a partial temporary cover. It also increases biota -- exactly the opposite of what humans tend to do, we are now in a major extinction event. Increasing biota on land is very hard and unlikely, but this easily increases it in the seas where it is badly needed. It is also easily titrated - one can stop/in/de/crease adding Iron and Phosphorus at any time.

A form of geoengineering is seeding Fe and P into appropriate places (good currents) of the ocean. This kickstarts aquatic life and removes carbon fast ... and as a by product creates whole new fisheries. It is fast and cheap enough that small countries and multimillionaires (and up) can do it as a DIY solution to climate change ... so why has this not been done, forcefully? There seems to be tremendous social opprobrium! A ~proof of concept has already been done.

Never could figure out people who actually wanted an internal PSU ... i thought big tech forced them on us for reasons of their bottom line: Ie as planned obsolescence. Eg one could easily make a svelte "phone" with a 30 second capacitor and Qi power transfer... Such would not wear out, letting one choose, swap, power backs/cases. Bigger things might standardize on wired connections like USB-C to cheap 18650 packs.

Easy to digest food for us ... is also easy to digest for bacteria, so they can forget about us and go straight to the source: https://phys.org/news/2019-05-overfed-bacteria-people-sick.h...

>Bicycle brings you to public transit. Problem solved

EVehicle brings you to public transit. Problem solved OW known as Park&Ride

>I have seen an equally shocking occurrence on a bike.

Yes, as a pedestrian in C in the 60's i was hit by a Cliffe on a bike ... going the wrong way on a one-way street, mind you. We, as a species, need to integrate more with others: We are not our bodies etc, we are the world

This is a shift from car centricity to a transport centricity for roads. Looking back in time we had one from horses to trolleys to cars. Now we could be beginning to see them in a broader light. Transport is growing now to include all kinds of electrified (and Rapid!) transit, eg scooters, ebikes, hoverboard... When i lived in Cambridge, ell before the concept of a protected lane, bicycling was commonly known and utilized as the fastest means of transport: the pinnacle of sneakernet.

>Russia has long expressed support for Assange. Russian Ministry of Foreign Affairs spokesperson Maria Zakharova said in a Facebook post after the arrest that "the hand of 'democracy' squeezes the throat of freedom."

Fair. Real time reportage:

>According to the Guardian, after it started to seem in recent weeks that an arrest might be imminent, big UK broadcasters had formed a "pool" arrangement to take turns staking out the building. If something happened, the footage would be shared among the pool members. >That effort appeared to have been abandoned when the arrest failed to materialize. The BBC, ITN and Sky News did not immediately respond to requests for comment.

>It was a moment that global news organizations were desperate to show their audiences. Yet it wasn't captured by leading UK broadcasters like the BBC, Sky News or Independent Television News (ITN). >Instead, the only media organization with video of the controversial moment was an obscure outfit called Ruptly. Ruptly, which has carved out a niche for itself by recording events around the world and selling the footage to other broadcasters, is a subsidiary of Russian state-backed media outlet RT. >Founded in 2013, the operation is headquartered in Berlin

AWS is by far the market leader in cloud ... this is a good reason to switch to its main competitors: Azure & GCP. They only got to be No! by network effects, not by being better.

Historically it was spreadsheets that killed (financier) interest in APL (which was going gangbusters at the time). They were much easier for this crowd. APL does actually work for non numerical stuff. There is the famous example of OS360 being written in a couple pages of APL code. The model was actually used at IBM and at the time was heavily used there. Iverson went on to shepherd J, a much sophisticated language. K, another much modern offshoot, in the mean time has taken over the financial (trader) world.

i have the additional requirement that it survives my death ... which rules out anything one has to pay for, or ping every x months, and self hosting (even ones house disappears on ones death).

The solution i have found so far is GitHub Pages. It seems the website, though static, can be arbitrarily deep and large.

The main transport issue the US faces is sprawl. NO one vehicle, certainty not EVs, can solve that -- it is a system level issue. However i do believe that the last mile problem can be solved ... making the solution of the overall problem soluble by (public) transit (on steroids).

The last mile issue could be solved with AV's (autonomous vehicles). Eg Ubers Jump could be outfitted to be an AV and transport Americans to a (usably frequent!) transit point. AVs could be made to work much easier (ie a shorter timeline) in the low density scenarios sprawl has produced, and which now make Public Transport infeasible.

Try looking for "third thumb". A DIY project where a guy got input from a toe to control a motorized second "thumb" on a hand. AFAIK no one ever made a project of it ... but ones feet are a vastly under utilized resource and could be re purposed quite readily. Eg why not control a virtual twiddler? Or indeed a "hand prosthetic".

Heh! Ifn i had it to do over i would prolly say FarceBorg. Not only do they encourage their users to make a Farce of themselves but they actively try to assimilate the web, and indeed the internet (the Basics).

There exists (or DID exist, before Google snatched up Marc Levoy and made the Pixel cams) open source cameras.

Levoy called the academic exercise he pursued the Frankencamera. (Look it up, a big thing at Stanford). Nokia took him up on it and produced an OTC "smartphone" ... before the iPhone.

i still have a N900 and it works: replaceable batteries do wonders!-) Runs unix etc. Open source camera software.
