Jet packs

In these two videos you see a jet pack(wiki) used for personal transport.

Apparently, this jet pack is powered by a stream of high velocity air resulting from the combination of two substances (hydrogen peroxide and another substance).

It seems that this means of energy storage could be applied with far greater efficiency for transportation in things such as a velomobile as a power assist. Or it may be suitable as a power assist for a moped as power assist.

Thoughts?
