Makani Power         
It appears that material assets will be up for auction at end of March and beginning of April:

Makani had intended to develop a 5MW version of its architecture (M5), hoping for a competitive unit-plant compared to HAWTs. Tallak can be certain that engineering scaling laws greatly prevented the M5 from development. Makani announced missed milestone after milestone during its 13yr run, due to well-understood aerospace challenges scaling up and automating aircraft.

Public measured comparison of Wing7 and M600 power curves would surely reveal severe square-cube scaling losses in efficiency, and that Makani likely will only share those power curves with Shell, who itself is under Google NDA, no doubt. The most experienced observers do know what happened. ~300M was plenty to prove informed doubts correct.

It seems very unlikely Shell let all Makani workers go, while intending to continue M600 development. It is time to spend money across all AWES architectures for systematic fly-off. Let the surviving M600 fleet be a part of that.

Google AWE Big Fail; who knew? "Right Stuff" aviation community, in 2009, on early AWES Forum.

Parties on heavily-censored New Forum seem not to have predicted Makani would fail, and are expressing shock and dismay. Aerospace and kite experts knew better, from the start (2007), and the failure was baked-in in 2009. Google has credibly shown to non-experts that safe reliable high-complexity AWE is decades premature, wildly dangerous and expensive, and will not scale well.

Low-complexity Open-AWE remains on-track to prevail at industrial scale on a ~2030 timescale, based on Critical Path and TRL metrics. Venture capitalist censorship of critical engineering perspectives still prevails in AWEurope conferences, and the new AWES Forum, but the field will only move upward, as losing ideas and ventures are relentlessly vetted.

=== Early AWE Forum Archives ===

Senior Boeing Engineer, Chris Carlin, chimes in with Dave Santos, on how Makani would never make it, just a day after they disclosed the losing M600 architecture in 2009. Open criticism as shared with dozens of aviation, kite, and aerospace pros.

Off hand I must agree. Why carry the generator and wiring up in the air when you don't need to. Minimizing weight and equipment aloft has to be a primary objective.

King of AWE (Airborne Wind Energy) hype, Makani Power is finally revealing its top-heavy technological approach to nonspecialized audiences while actively withholding key information about safety & reliabilty of its designs from the better informed AWE & aerospace community.
What are they hiding? Low MTBF, severe scaling limits, high flying weight, & nightmarish handling scenarios are just a start. Then what's up with "routine" test flying in Maui? Sweeeet, but surely not too smart or sustainable. But, hey, its Google dollars.
While poorly funded, its probable that the global open-source AWE folks have the better solutions & Google/Makani's deep-pocket VC hack gamble to go it alone, in secret, will prove mistaken. Lets hope open science wins by sheer brain power & nobler culture.
Stay tuned....
