Why would the operating costs be higher?
Father; husband; mechanical engineer. Posting from my self-hosted Lemmy instance here in beautiful New Jersey. I also post from my Pixelfed instance.
Why would the operating costs be higher?
Ah you’re right. Assuming an energy density of 160 Wh/kg that’s still almost 12,000kg. That much hydrogen contains about 400MWh.
A 240 tonne battery? That’s almost 240 tonnes less payload. They should make one that runs on hydrogen or ammonia.
This is how Willy Wonka’s Great Glass Elevator worked!
Cool.
I prefer “Yankees”.
Thank you!
Mechanical engineer here self-hosting my own Lemmy and Pixelfed instances in a Yunohost VM on an old Ubuntu box. It just feels better being my own admin.
I finally started on a project to improve the flowerbeds in front of my house. I removed the arborvitae and whatever was growing on the ends, replacing them with chaste tree shrubs. I also planted a line of bee balm in front. Hopefully they all take!
HB really requires hydrogen, which typically comes from fossil fuels. However, with some policy changes the hydrogen for ammonia production could come from GHG free sources instead.
Isn’t this the case for most of the ammonia based fertilizer used in all types of farming?
Doesn’t hydroponic farming already solve the weed problem without herbicides?
I think Yunohost is great. It was easier for me to set up that trying to figure out Docker. I run a few sites including AdGuard Home as well as personal Pixelfed and Lemmy instances with it in a VM on an older Ubuntu box. That said, I’m stuck on Lemmy 0.18.2 without pict-rs because the update script to the latest version available on Yunohost (0.18.3 with pict-rs) is broken. Oh well!
Ah, thanks!
Thanks!
One more reason that transitioning the car fleet to BEVs is a bad idea.
It’s crazy to me that policy makers insist that electricity generation has to be profitable. Just nationalize it. We could have a surplus of greenhouse gas free thermal power not only for electricity, but for heating and steel, fertilizer, and vehicle fuel production for years by now. Instead we have to wait to figure out how to satisfy investors and keep electricity just scarce enough.
Is this really still true about images federating in Lemmy? In any case, I think the problem can be avoided by disabling pict-rs.
Something to keep in mind is that trains don’t need tires.
I meant apart from the hydrogen fuel costs. It’s not obvious to me why the labor and maintenance costs of hydrogen powered mining vehicles wouldn’t be greater than that of the battery powered versions and the attendant charging/battery swapping equipment.
