Sorry, but who, except the odd American, has *empty space* next to anything that belongs to him? ;-) --[[Special:Contributions/162.158.89.199|162.158.89.199]] 20:47, 4 December 2017 (UTC) | Sorry, but who, except the odd American, has *empty space* next to anything that belongs to him? ;-) --[[Special:Contributions/162.158.89.199|162.158.89.199]] 20:47, 4 December 2017 (UTC) | ||

And really, if it moves, just keep the diesel engine in it, or switch to hybrid if you can. Batteries that are charged from power plants running on fossile fuel are an ecological nightmare. And car batteries are usually charged overnight, when solar panels are dead. --[[Special:Contributions/162.158.89.199|162.158.89.199]] 20:54, 4 December 2017 (UTC) | And really, if it moves, just keep the diesel engine in it, or switch to hybrid if you can.

:You are right that charging batteries from power plants running on fossile fuel doesn't really bring any ecological advantages ... assuming the engine operates close to optimal parameters. Most cars doesn't operate near optimal parameters inside city, but do on highways, hence hybrid. Also, it is much more ecological to have batteries charged by nuclear power plants. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 04:15, 5 December 2017 (UTC) | :You are right that charging batteries from power plants running on fossile fuel doesn't really bring any ecological advantages ... assuming the engine operates close to optimal parameters.

::Ja, Germany here. Our whole politics from left to right has this obsessive-compulsive nuclear-power-blows-up-and-poisons-everyone problem, so we're switching them off. --[[Special:Contributions/162.158.89.133|162.158.89.133]] 07:49, 6 December 2017 (UTC) | ::Ja, Germany here.

: I always thought of the main advantage of electrical battery powered cars (instead of petrol or Diesel powered ones) was not so much the immediate ecological improvement, but rather that (once they are the norm) you don't need to convince EVERY SINGLE CAR USER to get rid of their old car and get a new one (Like you have to do now, when you invent engines which use less fuel or something). Instead, when you change the overall energy production of a country (hopefully to something more sustainable and envronmentally friendly), the cars will just passively follow.

:: I think the main motivation for moving to electric vehicles is that it largely moves the pollution away from where people are. (From the energy production, anyway - particulate pollution from brakes, tyres, etc. is a whole other matter...)[[Special:Contributions/162.158.34.4|162.158.34.4]] 09:10, 6 December 2017 (UTC) | :: I think the main motivation for moving to electric vehicles is that it largely moves the pollution away from where people are.

I think that the reference to solar panels on roads in the title text could also be talking about the disaster that is solar roadways. | I think that the reference to solar panels on roads in the title text could also be talking about the disaster that is solar roadways. | ||

− | The reason that you don't want to put solar panels on something that is hot is not because hot things use more power. It's because the efficiency of solar panels decreases as a function of temperature: See here for example http://news.energysage.com/solar-panel-temperature-overheating/. This is why solar panels on a road are not a great idea (among other reasons).
