Hyperlon

That's what Ed Edd and Eddy live on.

I'm calling bullshit on that. Here's an article from motortrend showing it has a towing range of just about 100 miles. I've seen that backed up by numerous other tests. https://www.motortrend.com/reviews/ford-f150-lightning-electric-truck-towing-test/

I've seen references to the ICE getting 9-10 with a 23 gallon tank. That's more than double the range with a refuel time being an order of magnitude faster.

Batteries in trailers would help. However now you have a battery to tow, which would still have an impact both because of stopping and going and the DOE estimates for each 100lbs extra weight in your vehicle, your MPGs gets a ~2% reduction. Additionally I would not recommend strapping a battery to a boat trailer unless you are sure it was waterproof. Even then it would make it sink into sand easier.

You do what you want. But I'll make my infrastructure decisions based on my edge cases. Others will as well. Sometimes those edge cases are important to people.

Trailers have a habit of cutting the range by 66%. Someone I know has an EV and tows their bikes to a nearby city. They have to charge mid trip in both directions. That's unacceptable to me and a lot of others. I'm fine with a vehicle with 300 miles of range. But 100 miles of range to tow a boat? I wouldn't make it back without a recharge. Probably two charges because charging stations wouldn't be anywhere near the lake in rural areas. So in that scenario I would have to give up boating for an electric vehicle because I'm not about to do that.

This isn't like the consequences of adding a water filter means you now have to change a water filter every year, this is something that would turn a vacation into something unenjoyable. Meaning it's a decision that would make you give up that type of vacation if that's your only car. It's a sacrifice not an inconvenience.

I'd rather not refuel in -20F weather on a single trip. Add in a trailer and a road trip becomes a charging trip with intermittent driving.

Idk man, I'd be pretty excited if that were me.

I like the potential of the outside but it looks like they are using it as a billboard rather than a cool visual. It also needs a night mode.

Cave houses are where it's at.

Yeah, I've done something similar with ~120 wifi bulbs for a light show that responded to music and that worked fairly well but I doubt it would have worked with more than a few hundred.

If they were hardwired yes, but zigbee with millions of bulbs?
