At first it sounded amazing but then when gazing at this number it struck me suddenly - isn't this like an energetic equivalent of 0,5 ton of TNT ?

So if I rephraze this statement to "I cannot wait when I will be able to store half a ton of TNT in my garage" this whole premise starts to sound less and less appealing.

(especially since there was a electric scooter battery explosion in flat near me which killed someone)

now the display can directly serve ads!

(Like, firmware? Or is this more like an all-in-one type computer but the 'computer' part is equivalent to a Raspberry Pi/Arduino/etc [So - programmable, but somewhat minimal?]?)
