Magnet powered lights

There was this one guy promoting a magnet powered light that flickered
once per revolution of the wheel. This looks like a much improved
version, with 28 magnets near the hub in a continous circle to provide
a steady light.

Whoo hoo! A dynohub without the hubshell!
Oh, except it generates vastly less power, which is why it will (or at
least should) have vastly less drag.

I don't believe that flashing lights, other than turn signals, should
be used on roads. I find them as annoying as a pedestrian
intermittently blowing a police whistle for safety. I have seen
bicycle groups with a rider blowing a police whistle in the days
before HID flashing lights during daylight hours.

I don't believe HID lights can be operated in flashing mode.

(FWIW, I object to flashing /front/ lights also.)

Since this model has a 4 minute stand-light it probably has a steady
light mode (no flashing) because of a capacitor, not because it has 28
magnets.
The Magtenlight system seems to have all the disadvantages of the
Reelight system without its benefits of being cable free. Choosing the
Magtenlight over any cheap Shimano hub dynamo is just doesn't make
sense.

It has one apparent advantage over hub dynamos, which is not a small
one for most poeple. It doesn't require a wheel to be specially built.
