Nathan Ball who made this battery-powered rope ascender (and needle-free injection technology projects) that’s making its way around the news sites agreed to answer questions from MAKE readers, so post up your questions in the comments and once we get a enough good ones we’ll pass them along and post the questions & answers back here…

Pictured here –

Nathan Ball, hangs 50 feet in mid-air from his battery-powered rope ascender, a device that can raise more than 250 pounds at 10 feet per second. Ball is the 2007 winner of the $30,000 Lemelson-MIT Student Prize, an award that recognizes students at MIT who have demonstrated remarkable inventiveness.

The Rope Ascender created by Atlas Devices is a powerful new tool that enables “reverse rappelling” up buildings and other vertical surfaces at unprecedented speeds.
