My oldest has a robotic, self operating battery operated lawn mower that does it for him. Kinda like those auto vacuum cleaners. He enjoys it,, and says it does pretty good on his grass as long as it doesn't run into anything that stops it,, like a big tree limb or a high centering something.
I own a lot of battery operated tools that are wonderful. Makes my jobs a LOT easier for an old guy.
But,, when you look at the big picture,, and truly educate yourself on all this "go green & get rid of gasoline & oil operated machines,, I can't help but question several things.
EV's. Our current power grid,, can't handle it. Period. And we do not have the charging stations all over the country that could keep up with the demands of travel. Then there is the down time of charging. A gas engine operated vehicle can be refueled in a few minutes, and continue on it's travels quickly. Electric,, I've studied how it can add several hours to a longer road trip.
And what happens when a power grid area is overloaded & they have to shut it down. Now you have stranded people in that grid.
And the power grid system. What kind of system is used to generate power for the grid? Coal? Gas? Nuclear? Solar?
Then there's the actual batteries. The impact upon the environment to manufacture them from all I can find is huge. Plus,, what happens when they are dead & need disposal? Once again, an environmental impact that will affect things.
Let's go a bit further. What about all the farm tractors that need diesel or gas to work? Or the big heavy tractor trailers that haul all our goods daily all over? Battery operated machines like that will need HUGE batteries to even consider moving.
I'm all for doing things to make the world a bit better. But be realistic about it. There are MANY things we can do to reduce emissions, and cut out a lot of pollution. We've done a lot of good in the last several decades with recycling, or other things. But when you develop one kind of power,, look at HOW it has to be built, and what is the waste or excess, and especially the efficiency.
I know that battery powered items are here to stay. But the entire world,, not just the USA has to truly look at the overall effects of everything.
