Touch rugby sounds about as crazy as no-hands basketball, but leave it to some Kiwis to make it happen. Rush Rugby is both a product and a sport, developed and promoted by the new company PlaySmart. Tackles are made by a high-tech version of two-hand touch, where sensors on opposite sides of a player's shirt must be tagged within a short time period for a player to be down. The shirt lights up and makes noise when a player is tackled.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.

Umm, touch rugby has been around for years, it's a fun way to play a game without the risk of getting your clothes dirty, and it's safer when space is limited, such as playing in a garden. The Kiwis just brought some tech into it.
