    Counterpoint: blinking lights are in fact installed on airplanes both large and small. Red beacon lights blink, and so do high intensity white strobe lights. The variation helps identify the source of lights against a busy city skyline at night (that must be an aircraft we’re looking at) and serves to call attention against a sea of steady lights in the background. It’s very easy for the airplane to blend in otherwise. Even some racecars pulse their brakelights automatically to draw the attention of fellow racers. Finally, as a driver in sometimes poorly lit areas compounded with a rather avid local bicycling culture, I have found that bicycles equipped with rear-facing red blinking LEDs really help distinguish the bike against the background. The best setups had a light on the back of their helmets as well, which does the most to aid depth perception.

    Is every well thought-out response going to be met with the “AI” sneering accusation from here on out? Some people really are thoughtful, knowledgeable, and have enough empathy and concern to share their expertise with the world. I find this attitude here is yet another flavour of anti-intellectualism. LLMs got their plagiarised material from real people, after all.

    There’s definitely an interdependancy there, but don’t discount the incredible complexity of some cool civilan tech: James Webb Space Telescope, Mars rovers, ISS, the old Space Shuttle. Even mundane things like ocean-based oil rigs are chock full of amazing engineering.

    The home battery provides a backup source of limited power if the grid goes down, like a giant UPS. If one also has solar panels and/or wind generation capabilities on site, they have access to distributed domestically/locally sourced energy that isn’t subject to things like embargoes, war, and other supply issues that can affect traditional energy sources. In an off-grid application, that battery is the only way to use these sourced of energy when it’s night or the wind isn’t blowing. Unfortunately, these capabilities are more expensive than utility-scale grid power which can leverage economies of scale. An EV is able to inject many different sources of energy into the task of transportation, depending on how and where the electricity is sourced. This is an excellent way of diversifying the energy input portfolio instead of putting all of one’s eggs in one basket. Nuclear, hydroelectric, wind, geothermal, solar, natural gas, and coal come to mind. An ICE has much less choice and is therefore more beholden to economic fluctuations and vulnerabilities. I see a range of used EVs and PHEVs with costs equivalent or less to traditional ICE vehicles in my country. Certainly cheaper than many SUVs and pickups at least.
