Toyota Motor Corp said Saturday it is conducting trials of a vehicle powered by a hydrogen engine in Australia, making it the Japanese automaker's first such test of the environmentally friendly car on public roads toward its commercial use. In the trial from late October through January, a specially modified…
Wat? You sure understand what hydrogen is?
A fuel that is notoriously hard to contain and usually produced using fossil fuels, using inefficient production methods that waste electricity.
Anyway, the commenter you’re replying to is more referring to the pollution from tires and the noise.
And the death. Don’t forget the animal and human cost of everyone having a car.
What costs do you mean?
The animals and people killed by vehicles. The environmental impact those animal deaths can have.
Well, it’s either one or the another. While the energy loss is relatively high when using electricity, it’s not a problem when you have an oversupply of renewable energy, actually it’s even beneficial as it provides a storage for otherwise lost energy.
But regardless of the production, it generates no pollution when consumed by a vehicle. You know, like clean air in cities.
And of course, hydrogen won’t solve tire pollution nor associated noise (albeit I guess it should be more silent that fossil fuel one) but it’s still environmental friendly compared to what we have now.
Sprawl itself is also pretty terrible for the environment.
And it’s hard to build sprawling towns that don’t rely on cars, and hard to build dense towns where everyone drives everywhere.
