A Steam-Powered Battery Charger Seems Really Practical [Gadgets]
You read that right. It’s a steam-powered battery charger. Yeah, this is something we can picture everyone building on their own. Before you go and ridicule these people with emails they’ll probably never read (because they’re insane mountain people), the charger doesn’t charge your standard AA batteries. It charges a 48V battery bank. You know, to power their house. |
