Checking evaporation rates…
Each day really does give a new outlook on the ‘water on the surface situation’. Yesterday it all looked bad (wet!) but today was looking very encouraging, with much more area revealed from under the waves!
We did some experiments with salty and pure water to check evaporation rates and it looks like we are loosing 3-5 mm per day in these conditions, which is great news. If this continues at the same rate we should have a mainly dry surface in under a week. Fingers crossed! In the meantime we are finishing the last few technical details on the craft, electronics, etc.
Hi,
I found out about you just a few minutes ago, there’s a photo of Greenbird on the ‘today in pictures’ page on bbc.co.uk !
The very best of luck with your records, you’re the eco-friendly ‘Thrust SSC’ !
Good luck to you,
all the best,
Nick
P.S. Ecotricity, could you set up over here and teach the Aussies how to do Solar/Wind, they haven’t got a clue !

Not only a picture, but a complete interview ;o)

Anyway: Good luck with the new craft, I think your idea om adding weight in stead of using dynamic downforce must be an advantage, as the dynamic downforce inevitably will cause drag – and weight is not that big an issue, it only affects acceleration ;o)
With respect to the evaporation og the lake: I do remember an old article about the Bluebird speed record attempts in Aus – and having the water gone was not enough to get optimal friction conditions – it needed to dry up quite far below the surface to work. Dont know whether the same applies for you, but one would think: The dryer the better ?
Regards a follower of your quest for quite some years now ! ;o)
