Best Invention of 2014 (Kuala Lumpur)

What in your opinion has been the best or the most useful invention of Protected content far?

I will say a trash can that moves by itself to catch your trash! ha! the most interesting invention :D. No not really.

For me, its this simple invention that can save many lives on battlefield- XSTAT, a pocket-sized syringe filled with Chitosan; a substance that helps to stop bleeding and fight infections.

What's your say?
