We only need solar energy at 1 dollarcent or eurocent (it will get much cheaper still!!) and a little batteries for the convenience of using electricity when the sun does not shine.
In the north and south you need more solar panels in the winter than in the summer by a factor of 50. But that pays it back in summer when you have a squanderable abundance of free and clean energy. We can store that surplus energy in purifying drinking water, melting iron ore or aluminum [5], melting reusable plastics or purifying silicon ingots.
Storing surplus heat or cold in the ground is another luxury, because it is more expensive than 1 dollarcent or eurocent solar running a heatpump.
Wind and hydro are also more costly than solar so they are another luxury with worse environmental costs than pure solar cells.
We need to build Enernet, a peer to peer electricity net and internet between all buildings with power routers. for around 100 dollar per building. You buy and sell your house surplus solar electricity to the neighborhood where it can be stored in car batteries. See my Fiberhood white paper [2].
I don't understand the wood argument. Isn't it widely accepted we need to do burns to manage forests? Wood is a short-term cycle of carbon. It releases when it burns but frees up space to capture it right after. When people live on rural plots and trees fall, should they burn for heat (and lessen needing other energy sources) or let it decompose and cause the same thing? It's not the same as extracting deeply embedded carbon sources that won't make it to the atmosphere if untouched (fossil fuels)
Wood and plant burning requires a longer nuanced answer than the Hacker News format allows. Humanity must not cut forests or grow plants unnecessarily. If you must use wood to build a house -(there are better and cheaper materials in terms of energy and climate change enhancing emissions, see for examples Amory Lovins book Reinventing Fire or his lectures on Youtube) - then first grow those trees in a place that has no natural forest. And then do not burn the wood after you demolish the house. Do not use wood from forest, humans should let the forest manage itself.
Same with clearing the underbush of Meditaranian and hotter climate forest to prevent forest fires. If humanity had not managed those forest (grazing animals, building roads, harvesting) in the first place than there would have been no buildup of excess material that sustain wildfires past its natural rate.
The trick to forest management is allow or create small, frequent burns that clean up dry, overgrown understories. Nature does this without our help and some species even depend on it. If we interfere with this, eventually there's a big fire instead that levels the place.
Morphle here. Thanks for mentioning our work [1]. We still seek funders and students we can teach.
We build on the shoulders of the generation that built Smalltalk but just retired. There is a huge amount of documentation, science papers and talks on how to implement it all.
We are starting to implement the final step: An autonomous European secure operating system running a hierarchy of Virtual Machines (message passing parallel bytecode Smalltalk, Lisp, Erlang) and Qemu VMs with a modern GUI in less than 30.000 lines of source code that can be fully understood by a single person.
We improved our hardware to a manicore European Morphle Engine processor architecture that can run microcode, bytecodes, X86, Arm, Risc-V and other Qemu supported processors faster than the native chips.
We have some funding from Ukrainian drone innovators that need cheap computer chips manufactured in Europe, not controlled by the US or China.
We hope the European Autonomy movement away from US Big Tech clouds, operating systems, surveillance and chips with political kill switches and backdoors built in will fund our operating system and app software.
The Potsdam university (near Berlin, Germany) and Hasno Platner Instute [1] has been actively teaching and researching Squeak Smalltalk for decades. Same in Buenos Aires and several other places. Science papers every month for 5 decades, under many names besides Smalltalk. Weekly online conferences, presentations.
This lecture Alan aimed at this particular audience, the computer science (programming) students at University of Illinois, where they programmed the second browser, the second broken wheel 20 years after Alan and Dan had showed them how do do it better.
Dan Ingalls implemented most of Alan Kay's invention of the personal computer, in the following demo's he shows how to fix the webbrowser's broken wheel a bit.
The Lively Kernel would be another way to fix html but retain the web. Two demos says it all:

The Web is not HTML (and it's not JavaScript). It's URLs. It's a machine-readable graph of clickable references on cross-linked Works Cited pages. It's certainly not Smalltalk-over-the-Internet, and it's not trying to be (at least it wasn't when TBL created it).
The biggest problem facing the Web in the 90s and still today is that everyone who saw it then hallucinated TBL describing an SRI-/PARC-style application platform because that's what they wanted it to be—including people like Alan Kay—who then perversely go on to criticize it for being so unaligned with that vision.
It is both surprising and unsurprising (given this reaction) that the industry managed to make it all the way through the 90s without Wikipedia showing up until after the crash.
I will not invest any time in improving badly designed software. You can't fix a broken wheel. Your HN newsreader app tries to improve the broken wheel. The least you could have done is make the comment edit field WYSIWYG, make it modeless, see what the text will look like while you type, not after you click update or when you click edit in the tread reader.
Your code is just a very limited webbrowser. The webbrowsers, html are a very broken wheel. Alan Kay, the inventor of personal computing, explains why https://youtu.be/FvmTSpJU-Xc?t=961

Paul Graham should not have based HN (Hacker News) on the web and html but on WYSIWYG, then you would not have had to fix it with your app.

Warning! Badly broken user interface, I wouldn't trust these programmers to get the end-to-end encryption right.
On the second screen of the app there is already an infuriating bug: they ask to give your work email because than you go hire in priority on their invite-only waiting list. So you type in your email again and again and again, alternating between all your emails, but you keep returning to the form asking for your work email. You check those emails to see if they send you something to activate your account but nothing. Exasperated you try the only other button, sign up with private email instead. Guess that works, because you leave the infinite loop. But than zilch, nada, nothing.
Had no problem finding and downloading it from the AppStore; then again, it's been ten hours since you posted, so maybe it has only just popped up in the last couple of hours for people in the Netherlands.
Yes, we must. It is so rare to see someone saying this in public. Thank you for this simple clarity.
Stop burning everything! Fossil fuel, wood, plastic, garbage, paper. Stop making methane.
