That's good news. The project is refined.
Being hooked up with a club launching balloons stratospheric I think there is still consumption to decline.
- The camera unless it is high definition with lots of gadgets seems to consume me too much.
so the camera I chose 2 a micro cam that consumes 150mw and another 250 has 300w it is bigger and heavier but the interest is that it embeds a system of adjustment of the white for the against days and ca ca interest me
I would like to find a cam in high definition but must have a screen cappable to display it and a transmitter that can also transmit it briefly c galere I believe that to make beautiful pictures there is only the device foto

yes so I do not know exactly how its led the anteien of probe brooms nor mem what mass they can ship nor what modulation they use but I doubt to be able to make an anteine directive light enough to replace the anteine quard'onde original I will do a directive on the receiver is not a problem but hey I do not know if it will be enough
the links on the transmitters that I found

yen has another that only 100mW output and 100ma (we divide by 2,5 the conso but by 5 the power is not a good forward)

Obelix wrote:Voila for the conso. For the platform, I look rather for a hollow plane containing buffer batteries (Li-Po) and wind turbines on the top of the board. This concentrator for wind turbines placed at the top end.
For wind turbines taking a surface of 300 x100 mm and a wind of 5 m / s we should get to recover a half Watt (60 ma / 12 V).
so for wind turbines I'll see I have several constraints
- the assembly must allow to accept shear in the layers of air (wind direction different to the height of the mobile than that at the kite) without moving the camera: for that I have 2 choice be I I put it below with a joint or I put them elsewhere on the line it's possible but I must at this moment forget the upward movement or I bridle the wind turbines on the line above the camera but at that moment must I study how it behaves
- the assembly must be light and make a concentrator to accelerate the wind artificially it is on a mat fixed to the ground but on a kite line it will lead a very important aerodynamic drag I have to test to see how it behaves anyway I will do it in fabrics stretched on carbon rods. Without concentrator I should have 6 micro wind turbines which is about 150mm diameter which is a total if I do not dig 0.42 m² I have not yet understood the calculations to arrive at the power depending on the size of the wind turbine but if i do a report on your calculation i get 5.6W for 0.42m² I had to feed me somewhere at the same time the micro turbine manufacturer advertises 60W for a 10 turbine rack with 10m / s

I will have that 6 ca will have 18w (under 5m / s) no? or the la I am confused me
good go just knot the cortex for tonight!
a plus and thank you for all your comments it's cool!
