They have a few in the transport museum where I used to live. It's really eye-opening to see electric cars casually lined up next to steam powered ones -- and all the notes pointing out how the electric ones are better.
It was always just battery life and weight getting in the way. So, there probably isn't an alternative present out there with all-electric vehicles because that problem was just too hard to solve fast enough.
@katemorley Back in the 1970s when photovoltaic panels weren't very efficient I wanted to install solar water heating panels on our roof but the local authority refused planning permission saying that they would be aesthetically inacceptable because brown tile roofs were the standard in our neighbourhood. Now everyone has solar panels on their roofs. How things have changed !
@katemorley Some good detail on this and we are not sure on how it works exactly.

I am stunned! Unbelievable
and so awesome!
@katemorley Fascinating! The article also shows very well with the named years, how WWI and WWII killed every scientific development. Wars are an immense throwback.
@dan Before, they had even e-cars. The historical problem: fuel was a lot cheaper. And WWI was driven by cheap fossile fuels. Without them, people had not been able to install killing on an industrial scale. This industry was more important than individual cars (until Ford ... another story). @katemorley

Oh, thank you!
@katemorley Enjoy this bonkers article by Bellingcat researching the origin of that photo.
An inventor poses for a photo alongside his creation, then disappears.

@katemorley @BlumeEvolution @Ollivdb How do you plug such solar pannel to an AC grid? If you don't connect it to a grid, what does your electrical installation looks like, and what can you do with it?
My point is that solar panels are part of a system, and it's the system overall performance that defines if and how it'll be used.
@sstrader @katemorley So, according to Bellingcat, the photo is in fact not from 1884.
@sstrader @katemorley Bonkers. Thanks for posting this.
@katemorley
Two things:
My grandfather built a solar heater for his swimming pool that he and his son dug and built themselves. It was a grid of copper pipe along the back fence that recirculated through the pool. 1950s, not 1800s, but still... and prior to the 1965 Johnson report that laid out the risk of CO2.
I know you! (Not in person, just WWW) You taught me CSS tricks for expandable trees with neat graphics years ago.
@miermont @katemorley @BlumeEvolution
You totally missed the point
Pre-evolution... happens with everything we believe to be "advanced" technology, yet it's ancient.
Resonate something, with the correct vibrations it gets hot or breaks without energy released as heat.
Photoelectric, Einstein, wasn't the first time it was realized; most all concepts were thought of already.
