  • 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.

    I prefer the H.G. Wells The Time Machine style of time travel , where you affect the flow of time instead of a discontinuous jump.

    You’re still attached to your current location, things just happen faster (in forwards or reverse). It also means that time travel takes time, which can be a handy plot tool.

  • 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”
