Santos Disambiguating "HAWT" Oh, ha-ha, Loyd, in his haste, omitted mass as a
performance factor, which he well knew essential, as an avid kite
expert himself. Loyd decided conservatively to only include what was
first calculated. Even more absurd, his turbine-on-a-wing concept was
nothing but a calculation short-cut. He was appalled that it got taken
literally the boy-geniuses of GoogleX, but
was too shy to contradict (as I did from 2007-on, predicting "cannot
possibly succeed").
A close reading of Loyd shows he believed in
simple classic kites, just was not ready to do the math rigorously, and
then never got around to it. His paper then slept for 20yrs, hardly
noticed.
Had Loyd not cut those corners, Google might own
the sky. We even had to stop them from secretly
trying to privatize airspace in the US Congress.
Rebelling from the inside of the Joby-Google AWEC circle, I was the
whistle-blower to the aviation communities (AOPA, EAA, FAA etc.). The
skies remain open under the old "Freedom-of-the-Seas" legal principle.
AWE belongs to everybody!
Sorry Max, overlooked the "HAWT" question in the
haste to reply to substantial points. For decades HAWT has only meant
Horizontal Axis Wind Turbine, in wind tech (just as VAWT means Vertical
Axis Wind Turbine). This is standard usage for surface-based wind
turbines, but we sometimes use HAWT in context of AWES mechanisms.
A funny aspect of AWE has been how various parties
attempted or succeeded in naming things. GoogleX's venture, Makani, now
defunct, tried vainly to re-coin HAWT to mean "High Altitude Wind
Turbine". Because Google wrongly dominated Search results, they could
somewhat redefine terms at will, but conventional wind experts have
never wavered from original standard usage.
Joe and I have coined more terms in Kite Energy
than anyone, even "AWE" itself. The FAA would even have adopted "AWE"
officially, but that acronym was already in use in the FARs. We settled
on "AWES" for FARs use. As lexicographers of AWE, we can generally
identify the origin of every novel term-of-art, and settle best-usage,
and continue to recognize and coin AWE terms as needed.
There are several other orphaned AWE
coinages out there, like Loyd's "Lift" and "Drag" modes, which he
personally disavowed to me. These terms continue to muddy the water.
Loyd was in a hurry when he knocked-out his classic paper, not
realizing it would be taken so canonically.
