Nanotech now has the capability to make the space elevator and private 
orbital launchers possible.
It now also makes possible the long desired 'flying cars'.
The purpose of this crowdfunding campaign is to prove it.

Flying cars have been around since well before WWII but the lack of
wide spread adoption has nothing to do with materials and everything
to do with economics and regulatory approvals.

Repeating nonsense does not make it true.

As a physics guy, you might like this. Sharp points are known to more easily 
create corona discharge and also more intense ones:

Corona discharge.
[Quote]
When the potential gradient (electric field) is large enough at a point in 
the fluid, the fluid at that point ionizes and it becomes conductive. If a 
charged object has a sharp point, the electric field strength around that 
point will be much higher than elsewhere. Air near the electrode can become 
ionized (partially conductive), while regions more distant do not. When the 
air near the point becomes conductive, it has the effect of increasing the 
apparent size of the conductor. Since the new conductive region is less 
sharp, the ionization may not extend past this local region. Outside this 
region of ionization and conductivity, the charged particles slowly find 
their way to an oppositely charged object.
https://en.wikipedia.org/wiki/Corona_discharge

The same is also true for very thin wires, a fact well-known to electrical 
engineers by Peek's Law, https://en.wikipedia.org/wiki/Peek%27s_law . So for 
ultra thin wires such as nanotubes would the same thing be true? A key fact 
is it has already been confirmed for nanotubes in regards to sharp points:

Why are carbon nanotubes such excellent field emitters?
by Jean-Marc Bonard, Jean-Paul Salvetat, Thomas Stöckli, László Forró, André 
Châtelain
http://www.foresight.org/Conference/MNT6/Papers/Chatelain/

This *strongly* implies this will also be true in regards to ultra thin 
wires such as the nanotubes. But that's it, that's the game changer. Once 
you have that, you get the conclusion the force produced using nanowires, 
i.e., wires at the nanoscale, would be enough to lift the raise the lifters 
and their power supplies. For the equation showing the thrust for the 
lifters is simply:

F = i*d/k,

i the current, d the distance between the emitter and collector, and k a 
constant for air known as ion mobility, k=2*10^-4 m^2/(volt*sec) at STP, 
with all variables in MKS units.

Therefore the thrust to electrical power ratio is F/P = F/(i*V) = d/(k*V). 
See for example this published paper:

On the performance of electrohydrodynamic propulsion.
Kento Masuyama, Steven R. H. Barrett
Proceedings of the Royal Society A
Mathematical, Physical, and Engineering Sciences
Published 3 April 2013.DOI: 10.1098/rspa.2012.0623
http://rspa.royalsocietypublishing.org/content/469/2154/20120623 [full text]

So you see if you can get V small, you can get high thrust to power ratio. 
But you can't just arbitrarily set V small. V has to be of a size to 
initiate corona discharge, i.e., ionization, around the wire. Then that's 
the key point: with wires at the nanoscale Peek's law suggests, and 
experiments with nanotube sharp point emitters implies, that you can get 
ionization at just a few hundred volts, a hundred times smaller than with 
the voltages used now, which thus would correspond to thrust/power ratio's a 
hundred times higher than those attained now.

Note also you don't need nanotubes to confirm this. It can be confirmed by 
using any nanowires, such as used in microelectronics for example.

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

A 75 kW aircraft engine is a tiny engine.

The power has to come from somewhere.
