Helium Back Pack
Alot of people these days back pack all over the world and tons of people join camping expeditions and challenges such as eco challenge which require you to carry your ten tonned bag pack all over the country. This can be energy comsuming.

Here's an idea i thought about. Attach a mini helium baloon on the top of the bag pack. The force of the baloon going upwards will help lighten the weight of the bag pack. The bigger the baloon, the more weight it will take off.

Only problem is that you'll need to carry gas tanks around to fuel the balloon. I also thought of creating a back pack with pockets which are filled with compressed helium maybe it'll help? If left unattended... their back pack may end up in another country.

Any ideas anyone??
