Foil Pouch VAWT Barrel Turbine (Solar Hot Air Balloon)

Thin copper metal foil barrel super hot air balloon with surface triangle pouches, tethered via central pipe axle to ground generator, self-floating with hot-air starter and continue to float with solar heat, wind profile rectangle area A=2rh, hot air volume V=pi*r^2*h. The copper metal surface outside can be torched/burned to black, making it a thermo-couple sheet, being able to generate direct current from the solar heat. Typical balloon size r=5m, h=20m, A=200m^2, V=1570m^3, wind power 40W/m^2 at 4m/s, power P=8kW at 4m/s, wind power P=½qv^3, where air density q=1.2kg/m^3. Can be used a wind catch tower when 4-point cable tethered in place, also as solar heat and rain water mist collector. Hot air density 0.9kg/m^3 at 100C, 0.27kg/m^3 at 1000C. Copper melting point 1100C, density 9g/cm^3. Can be made a hot-air floating wind catcher fast deploy balloon tower with outer double layer air compartment.
