I agree. But installing a waterboiler on a roof right above a shower is a lot simpler and probably still cheaper, for example in a camping hut situation, so off grid

But t solar boiler can still be useful in some cases. Where heated water in “solar” on the roof is used immediately for shower etc.

The efficiency of an EV SUV will never be anywhere near the efficiency of an (electric) bicycle. Motor and battery efficiency also improves for bicycles. The bicycle will always need only a fraction of the resources, in materials, electricity and occupied space.

It embeds the existing dominant individual, resource-wasting mode of transport even deeper into the culture (and urban planning). That makes it a negative for urban environments. Bit different story in very sparsely populated areas.

haha didn’t think of that yet. The “thank you” from trump to Qatar, Bahrain, Arab Emirates, Saudi Arabia, Jordan: quite a few of the members got fucked over very quickly with the generous gift of regional instability!
