No, they don't. This isn't "feel-good technology". We're talking about saving the ecosystem and providing for posterity.

There are no ifs, ands or buts about it, we have to return the energy we borrowed and rebind the carbon in our atmosphere. It doesn't matter if thereisnospork doesn't see the utility in this, it doesn't change reality. So again, the energy is not being wasted. It's being used. Just because there isn't a net 0 expenditure doesn't mean it's a stupid idea, that sounds like a Conservative talking point waiting to happen.

No, we are talking about effective ways to save the ecosystem, and this technology is effective in the same way a unicycle is. It works, but only an idiot would propose investing in unicycles over bicycles or scooters or electric cars (etc.) to green up urban transit. Don't be that idiot.

So energy is only meant to be used for powering our frivolous lifestyles but we aren't allowed to store it for later use while simultaneously fixing our atmosphere? Lol okay.
