Australian Air Born Wind Energy Bought by Google
Timeline to SuccessSaul Griffith an Engineering PhD from Sydney co founded Makani power in 2006 with two others Don Montague and Corwin Hardham who has sadly passed away. It was kick started with a grant from Google’s Renewable Energy Cheaper than Coal fund (Rec).They set out to take a new approach to wind. They based their tech on a little known paper written in the 70s that described a new method for getting power from the wind, using a kite.According to Saul’s presentation at a TED talk, a free flying wing will sweep through more air in the same amount of time than a traditional turbine blade generating greater energy output.He talks about the limit to the height of traditional masts being unable to extend much further, though the higher you go the more wind you get.Saul moved on in 2008, but by 2013, they’d managed to build a 30kW prototype model that was capable of hours of unmanned flight. The small generators are located on the wing itself, and transfered to the ground by a tethered cord.It wasn’t disclosed how much Google paid, but they’d already put over $15m into the business thus far. Their initial goal was to be cost competitive with traditional wind, since the Google acquisition it’s unclear whether or not they are continuing in that same direction.Could you see 6MW turbines with wings the size of the spruce goose flying over offshore locations in Australia?Mentioned in this podcast:Makani PowerTED TalkYoutube Video of FlightThe top wind farmsMacathur: $1.9MLake Bonney II: $860kWaubra: $750k

What is really behind the 20% power price spike in Queensland?
Welcome to Episode #1, inside this week’s podcast:How much money revenue did all wind in Australia generate this week?What is really behind that 20% power price spike in Queensland?Mentioned in this podcast:Dean Spaccavento from mistervint.com where you can see wind usage as it happens.The big question:Do you think ENERGEX is experiencing the “Death Spiral”? Leave your comments below, and I’ll read through on next week’s show.Show Notes$6.6M wind farm revenue was calculated from the following wind farm locations:'BLUFF1': "SA1", 'CAPTL_WF': "NSW1", 'CATHROCK': "SA1", 'CLEMGPWF': "SA1", 'CNUNDAWF': "SA1", 'CULLRGWF': "NSW1", 'GUNNING1': "NSW1", 'HALLWF1': "SA1", 'HALLWF2': "SA1", 'LKBONNY1': "SA1", 'LKBONNY2': "SA1", 'LKBONNY3': "SA1", 'MACARTH1': "VIC1", 'MTMILLAR': "SA1", 'MUSSELR1': "TAS1", 'NBHWF1': "SA1", 'OAKLAND1': "VIC1", 'PORTWF': "VIC1", 'SNOWTWN1': "SA1", 'STARHLWF': "SA1", 'WATERLWF': "SA1", 'WAUBRAWF': "VIC1", 'WOODLWN1': "NSW1", 'WPWF': "SA1", 'YAMBUKWF': "VIC1"It was for the week between (Wednesday) 5th June and (Tuesday) 11th of JuneCorrectionIn the podcast I mentioned that the wind industry earned $6.6M, but I left out Woolnorth. Somehow it wasn’t on the list. Including that rather large wind farm brings the total to $6.9M
