Submission + - Japan's silent submarines extend range with lithium batteries (nikkei.com)

AmiMoJo writes: The world's first submarine powered by lithium-ion batteries was launched on Thursday. The submarine can reach speeds of roughly 20 knots and displaces 2,950 tons. It will be delivered to the Japan Maritime Self-Defense Force in March 2020. Batteries are recharged by the energy generated by Oryu's diesel engines. The vessel switches to batteries during operations and actual combat in order to silence the engines and become harder to detect. The lithium-ion batteries radically extend the sub's range and time it can spend underwater.

I use both in case I get a call while driving. My car's gps system in there is great, reports traffic, reroutes automatically and the updates are free. The problem is the address entry, it is a pain in the ass if you're going to a place you haven't before. The features in Waze are getting better and better so it is my go to. So why the hell don't they just put Waze in cars?

I have played them all and I think SimCity 3000 is my favorite. The new one is a bit too ridiculously complex and 2000 is a bit too simple...and the sims nagged the hell out of you. With the new one I'm constantly having to deal with shit. I don't mean a bunch of stuff shit, I mean shit, sewage. Constant problem. I don't like dealing with poo in real life, and definitely don't want poo in my games. I guess it's realistic enough.
