Are you not familiar with helium dirigibles? They were safe, efficient, and fast transcontinental transportation in the 20s' and 30's. Especially in and from Germany.
Until the US banned the export of Helium, Germany had to switch to Hydrogen.
It's not a stretch to transfer that technology to much smaller scales, even down to the individual.
a personal zeppelin seems impractical for the run to work or 7-eleven but it does solve the problem of taking a zip line uphill...
