A road built and maintained by taxpayers is much cheaper (to a shipping company) than building, maintaining, and operating a railway. Making taxpayers responsible for the infrastructure you use is one way to make your business much more profitable.
Yes, but that’s all subsidized by taxpayers, so it’s more expensive overall but cheaper for YOU.
It’s not a loop, there’s a fresh towel roll and a dirty towel take up roll and it only rolls on one direction. You changed it when the clean roll ran out and washed the dirty roll.
The towel is not a loop. When you pull down you get fresh towel off of a roll. The used towel goes onto a different roll and when the clean roll is used up they change it and wash the dirty one. They are geared together so the amount hanging down is pretty constant but sometimes they got out of sync and the “loop” was either huge or so tight you couldn’t really dry your hands.
I have no idea what you are trying to say. Batteries have an environmental impact, but so does fracking for natural gas. You have the impact up front making a battery, but charging it with renewables does not have continued environmental impact. But if you use gas, you’re going to have to use an awful lot of it over that time period to offset the clean power you’re able to use when you have a battery. And that gas has a very high environmental impact, continually, over that entire time period.
I didn’t say batteries have NO impact, but they have less impact than continually mining and burning fossil fuels.
You make the batteries once, and the pollution due to production is spread over the 10-15 year lifetime of the battery. During that time gigawatt hours of clean power sloshes in and out of them. This in contrast to having to produce enough gas to make all of those gigawatt hours once, then throw the gas away as co2 and get more, along with the attendant pollution.
