Again same goes description goes to this role, was imagining male american adult but all may apply.

This video isn't a tutorial video though, it's more of an introduction video to engage the audience.

Make sure it is just that - engaging

Imagine really cool visual effects going round a globe and music from something like tron legacy. Get the tone serious with a slightly epic hint (but don't go theatre on me), perhaps try something more corporate and try something more epic so I get a feel between the 2.

If the above doesn't help, try these directions: 

Imagine your in an intergalactic board room meeting about a pending alien invasion and you are trying to sell some new technology that will help defend you against the aliens, as you speak to the boardroom some giant cool holograms of the globe etc materialise behind you. Keep it cool though but I want to believe that you know what your talking about.
