i got a solar charger the other day. i can't believe how effective it is. in strong sunlight it charges as fast as the wall. free power from the sky. incredible.
what tech has really blown you away recently? are you still capable of being impressed in the futuristic times we live in?
I think blockchain technology has impressed me most. It's revolutionalized the global financial sector with ideas and a possible second generation Internet through its decentralized network.
