Older. probably, and 2-stroke which necessarily burn some oil and
produce blue smoke. Another reason why I like my 4-stroke Ryobi.

I think that not seeing or smelling any 'exhaust' doesn't help us
remember we are still producing pollution.

The same reason we (had to) deal with the London smogs, are now
dealing with 'other' pollution in the same place (and similarly around
the world) and make domestic gas smells so we are reminded it's there.

It's the same thing with electric machines of course, assuming they
aren't only using generation techniques that don't (directly) burn
fossil fuels, it's just that the pollution is even further out of
sight (and so further out of mind).

It's like when we 'throw something away', where is that exactly and of
course 'most people' don't care as long as they don't have it any
more. ;-)
