Good question. You can make one of these EHD devices yourself, commonly
called "lifters", to test this. Do a web search on: "lifters" and "power
supply" for the many explanations online for how to make them. My guess is
since it's the intense electric fields that is creating the ionization they
will still work in high humidity or rain. Note also the EHD effect also
works with liquids.

Finally, nanotechnology can now fulfill its potential to revolutionize
21st-century technology, from the space elevator, to private, orbital
launchers, to 'flying cars'.

Abstract
Peter Thiel of the Founders Fund once famously said, "We wanted flying
cars,
and we got 140 characters."But nanotechnology now does make possible the
long desired flying cars. It's a different propulsion method though than
propellers or jets however. It's propulsion by electric fields known as
electrohydrodynamic propulsion (EHD). It works by ionizing air then using
electric fields to propel the charged air molecules rearward, thus
producing
thrust. It's quite analogous to the famous space ion drive of NASA. EHD
has
been known at least since the sixties. Its problem is, as with ion drive,
the thrust is so low. So far the EHD craft have not been able to lift both
themselves and their power supplies. The ones made so far leave the power
supply on the ground and connect to the craft through power cables. But
the
equations of EHD suggest the thrust for the power required gets larger for
thinner ionizing wires. In fact if the wires are at the nanoscale then
this
important thrust-to-power ratio can be a hundred times higher than for the
craft constructed so far. This would be enough to lift the craft and the
power supply. This research is to prove what the mathematics suggests.
Note
that if it works then all propeller and rotor driven craft become
obsolete.
Also, intermediate range automobile travel would be taken over by the EHD
craft, so a large proportion of carbon-emissions would be eliminated,
replaced by this zero-emission travel method. In regards to space
propulsion, since EHD is so similar to ion drive, using components at the
nanoscale may also work to improve the thrust of ion drive. This would be
important to shortening the flight times of spacecraft using such drives.
This is important not just for robotic spacecraft but also satellites that
use such ion drives to reach their final GEO destinations. As it is now,
the
ion drives used have such low thrust it takes months for such satellites
to
reach GEO, resulting in millions of dollars of lost revenue to the
satellite
companies. Being able to increase the thrust of these drives would reduce
the flight time, and therefore reduce this lost revenue.

Do they work when it's raining / in humid environments?
