The Jet Pack is a straight forward, direct approach to making someone run faster. After conducting testing using a load cell and electric golf cart, I found that there is a specific thrust to body weight ratio that works best. Clinical tests have been performed and the jetpack has demonstrated increased running speeds up to 20mph and significantly lower a runners heart rate. The jetpack makes it 33% easier to run based on Vo2 (oxygen consumption). Stay tuned in the near future for an awesome episode of Tech Toys 360 featuring the 4MM Jetpack!
