The 2 best new products or inventions that most people don't know about are...

 When I think of best new products, I think of products that solved a problem we previously thought was not possible.

Examples:

• Use an umbrella in windy weather, and you know how pointless the umbrella becomes. A relatively new umbrella, called Senz stormproof umbrella,  can withstand wind speeds of 100+ km/h.

• Alfa is a cardboard bicycle made 100% from recycled materials. Amazingly, it is both waterproof and fireproof. The inventor, Izhar Gafni, and his business partner ERB has an ambitious goal of manufacturing these bikes for $9 to benefit people in the third world.
