Drone toys have short battery lives because of the
energy
required to keep them aloft. Lighter-than-air devices
seem to
make sense to address this, and that's probably a big
reason
why helium drone toys are baked (although
unfortunately
uncommon). Helium is expensive, though, and such
toys
either require the user to get their device filled from a
third-
party vendor or deal with the complications of getting
helium
shipped with the toy. Proposed is a drone toy that
includes a
water electrolysis kit so the end user can fill or refill the
air
chamber with hydrogen. The gas needn't ever be
compressed
very much at all.

The excitement factor is going to drop if a blimp is attached
to those racing drones. Although, birds do have hollow
bones for weight reduction. |

// The gas needn't ever be compressed very much at all. // |
|

The whole point is that , unless required to maintain structural integrity i.e. a blimp, the gas is at atmospheric pressure; that's certainly the case in a classic dirigible. |

[8th], if you //fill or refill// the zep //at atmospheric pressure//, you'd
need to be rather patient, no? It doesn't need to be pressurized in the
gas bag, but your filler bottle would probably want at least a couple of
PSIG. |

The storage containers would be HP, but the pressure difference to get the gas into a bag need only be a few Pascals. Zepp bags were "atmospheric" and indeed had vent valves, so that if the ship rose above its pressure altitude, the gas could vent to prevent bursting. |

If the "Low Hydrogen" status light comes on when the wall-wart is plugged in to recharge the batteries, inject a cc or so of water into the H2O port. |
