Bat Conservation International was founded in Austin, Texas, where kPower is based, so we have a particular interest in the Bat, as “Bat Capital of the World”.
Again, faster more-aerobatic AWES wings present the greatest inherent danger to Birds and Bats, demanding the greatest mitigations. Its hoped by kPower that large slow kites will not present any serious danger to Bats. Slow kite wildlife advantage extends over conventional wind turbines, not just fast AWES.
It seems bats are a serious issue for AWE flying in 1000 m altitude easily…
In terms of conspicuity of AWES Systems and also when considering the human environment such as in
How about when we have a flashing light on a looping AWES…
Does it have to be a regularly timed flash or…
Having the majority of light flash visibility above the top surface of the AWES and only at the top point of the loop… This would likely have no effect on the ability for air traffic to spot the kite yet would also reduce the impact on dark sky environmental enjoyment on the ground.
There needs to be continuous conspicuity for looping kites, not just the deceptive illusion of a top station-point. The novel danger is aerobatic trajectory where the unit dives at high speed into another altitude-airspace. Hard for birds to adapt as well. Blame the design not the victim. Its harder to design a beacon that only flashes at zenith.
Also, Kitepower’s recent breakaway dragged a tether in Valkenburg that was apparently charcoal grey, perhaps the least visible (but most fashionable) color in the Netherlands. Best practice going forward, especially for single-line AWES, is high-visibility tether colors, for less danger when dropped/dragged across roadways, etc. See Old Forum for more.
