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?
The technology that impressed me the most is the salt water powered plant. It is designed for a fishermen who doesn't need to get an electricty to power a lamp but saltwater. It is an invention of a filipino designer which her objective is to help people which incapable of getting electricity from the power plant.
