Britain's 'Iron Man' has unveiled his newest suit...

all powered by electricity

Location: West Sussex, England

(SOUNDBITE) (English) RICHARD BROWNING, FOUNDER OF GRAVITY INDUSTRIES, SAYING:"So the electric version is really, I suppose, a physical manifestation of our desire to constantly push the boundaries of what's possible. It is right on the margin of what's possible because of energy density and batteries. And yet we've actually managed to go and get it to work today. Honestly, 24 hours ago, it wasn't really achieving what we needed. And we put our money where our mouth is and actually demonstrated it live to people. So it's the beginning. As battery technology gets better and better, it will get better and better and we'll see where we get to finally."

The current batteries can get a human airborne for a few seconds

compared to the four minute flight time of the jet fuel-powered model

Gravity Industries has demonstrated their jet suits to the Royal Marines

to test how the product can assist in military operations
