But we only have your word on the working device.  To put it bluntly, your
credibility is in question.

For example, let's put the 10km 30 degree road into perspective.  One of th=
e
longest climbs of a road over a relatively short distance I'm familiar with
is US 34 as it climbs west from the plains over the continental divide in
Rocky Mountain Natitional Park in Colorado.  The highest section is locally
known as Trail Ridge Road.  It used to be the highest continuous paved road
in the world.  I don't know if it still is, but it must be near the top of
the list.

Out of curiosity, I checked it with Google Maps to get the elevation and
DeLorme street atlas to get driving distance.  I took the section from abou=
t
where the plains end and the mountains begin (that happens quite abruptly
there) to the Trail Ridge Road high point.  According to the two sources I
cited above, the length is 43.6 miles.  It starts out at 5078 feet and ends
at 12150 feet for a total rise of 7071 feet.  The start and end points are
at (40.4130 N, 105.1689 W) and (40.4111 N, 105.7318 W) in case anyone wants
to verify my figures.

7071 feet / 43.6 miles =3D 3.07%.  That's a pretty decent grade for a real
road to sustaiin for over 40 miles.  3.07% grade means a up angle of
AcrSine(.0307) =3D 1.76 degrees.  There might certainly be a few steeper
roads, but one with a angle of 30 degrees, which is 50% grade, is really
really hard to imagine.
