  • Assumption:

    Someone crams a 300 watt solar panel onto the roof of their EV and manages to integrate it into the charging system so that it’s pretty efficient to use that power.

    Numbers:

    One hour of good sunshine on the 300 watt panel = 300 watt-hours (Wh).

    Average EV energy usage : 200Wh per kilometre these days. Maybe a little more, maybe a little less, depends on how and where you’re driving.

    Result:

    One hour of perfect sunshine hitting the roof of your car equals 1.5 kilometres of extra range, or you can drive your car in a steady-state fashion at a 3-5 kilometres per hour because an EV is more efficient than the average usage at lower speeds.

    Conclusion:

    Probably better off increasing the storage capacity of the battery as a full day’s sunshine will get you about 10 kilometres of range.


  • You need silicon.

    The earth’s crust is about 25 percent silicon. Sand made out of quartz like desert sand is about 50 percent silicon. Beach sand is usually mainly calcium carbonate from shells and it doesn’t contain much silicon at all. Volcanic beach sand is more likely the same as the earth’s crust so 25-50 percent.

    So as long as you refine your sand/gravel/rocks/lava so that you’re left with pretty much pure silicon, you’re good to go.


  • i like how the answers are the exact same generic unhelpful drivel you hear 20k times a month if you’re…

    Searching for a solution to any problem on the internet.

    There are a million ad- laden sites that, in answer to a technical question about your PC, suggest that you run antivirus, system file checker, oh and then just format and reinstall your operating system. That is also 90 percent of the answers coming from “Microsoft volunteer support engineers” on Microsoft’s own support forums as well, just please like and upvote their answer if it helps you.

    There are a million Instagram and tiktok videos showing obvious trivial, shitty, solutions to everyday problems as if they are revealing the secrets of the universe while they’re glueing bottle tops and scraps of car tires together to make a television remote holder.

    There are a trillion posts on Reddit from trolls and shitheads just doing it for teh lulz and Google is happily slurping this entire torrent of shit down and trying to regurgitate it as advice with no human oversight.

    I reckon their search business has about two years left at this rate before the general public regards them as a joke.

    Edit: and the shittification of the internet has all been Google’s doing. The need for sites to get higher up in Google’s PageRank™ or be forever invisible has absolutely ruined it. The torrent of garbage now needed to ensure that various algorithms favour your content has fucked it for everyone. Good job, Google.


  • I work in OT. The number of “best practice” IT mantras that companies mindlessly pick up and then slavishly follow to the detriment of their mainly-OT business is alarming.

    Make your own damn best practice that suits your business best, don’t copy and paste something from a megacorp. Sure, include elements from megacorp’s best practice if they are applicable, but don’t be a slave to the entirety of it.









  • I can read and skim documents for salient details at 500 - 800 words per minute.

    And then someone links me to a twelve minute video on YouTube where 800 words are spoken in total , 300 of those words are “um,so”, and all we’re looking at is either the narrator , or possibly a static slide with a few paragraphs on it… and also an inset of the narrator, narrating.






  • Similar things have worked in countries that aren’t so under the thrall of the mighty corporation. I recall some guy in … Russia? who struck out and reworded a bunch of penalty clauses for a credit card offer he got and mailed it back to the bank, which accepted it and issued the card. Cue much hilarity as he racked up a bunch of charges and then got it thrown out in court. (Actually, here’s a link.. They eventually settled out of court for an undisclosed sum.)

    Anyway, I live in Australia so my response to all these kinds of attempts at removal of my consumer rights is a drawn out “yeah, nahhhh”
