It's not the same. This is the MIT press release https://newsoffice.mit.edu/2015/solid-state-rechargeable-bat...

This really should be the link for this whole thread. First, it has some actual interesting details. Second, it hasn't been round-tripped through Google Translate.

This looks amazing. I wish the app was available to us foreigners as well.

I am about to buy an iPad for the first time, and I thought "this would be a great app, cool!" and clicked on the store link.

So annoying that it's US store only - why do devs do this, anyone know?
