Pros and Cons of Ventilation and Exhaust Systems

Meet up for a beer sometime.

where should I pick you up

Calling someone who has studied environmental protection and has it in their title unqualified is more than presumptuous!

At least I live my views and save the planet more than one ton of CO2 per year!

I do my trips to work by bike and of course without electric assistance; travel time 40 minutes each way...

There are simply too many of you, you are right in the middle of the hamster wheel and don't even notice it...

Hard fate.
It's okay if you like the storage. It does have its use, just not an economic one. If you want it for idealistic reasons, go ahead. But also think about disposal and where the lithium probably comes from.

By the way, hamster wheels generate electricity wonderfully.
I don't see any titles in Tapatalk. I also wouldn't know what that would contribute to the matter, because apart from meaningless phrases you haven't shown anything so far that suggests qualification.

PS: By the way, I am a licensed singing bowl therapist and still know more about the profitability of photovoltaics than you.

Children...

Give batteries another 10-15 years, then the ROI will look different.

And the discussion about cars isn’t worth it. If individual mobility beyond the bicycle is needed (not everyone lives within cycling distance of their workplace, sometimes cargo transport beyond the capabilities of walking and cycling is necessary, the frail mother needs to be driven to the doctor, etc.) the question of economic viability simply doesn’t arise.

Then it’s binary: mobile? YES/NO

I’ve always said, if YES, you buy a used car, maintain it, drive it until it’s scrap, and then buy another used one. Wasting resources on a new car... uh, having to be used, that’s really unnecessary.

Regarding lithium: there is plenty of it, easily accessible, and it can also be recycled excellently.

At the current pace of technological development, it may be that in 15 years the battery discussion will seem as if from another planet.

( Wasn’t the topic here something else before? )

You only think you know more!

We were not talking about the profitability of photovoltaic systems, but about their storage.

And my tone was from the beginning, it doesn’t pay off or only very late!

I analogized it to the automobile and conveyed the equivalence of meaningfulness.

I am aware that one must not criticize the Germans’ favorite child; the holy grail must remain untouchable!
