We signed up for a service last year that uses only electrified/battery powered devices (as opposed to IC engines), mainly just for the green aspect of it. But I'll be danged if they're not also like a third the volume of the gas ones! The first time they showed up, my wife saw a dude walking back and forth behind a push mower (looking out through the closed window of her office), and she thought he literally didn't even have it on yet. That's how much quieter they are. I think that's a damn good balance. Dudes with reel mowers and rakes are gonna be out there for like two hours every time they come; very not interested.
I mean, I'm sure humanity pumps that much water, in aggregate. If you look at every pumped system everywhere in the world, it's no doubt many times Niagara.
Now, doing it all in one place, like that? Yeah, for sure, that's tricky.
I love how you typoed "rentalars" where presumably you meant "rentalcars", but they saw your no-typing ass coming and it redirects to the correct site.
