SOLAR POWERED BOTTLE BOAT - air drive propeller

Following on from his Action Man inflatable conversion, James gulped down 4 Sainsbury Apple & Blackcurrant drinks to give him a floating base.  He then bent 4 metal rods to form a frame, which he (hot) glued to the bottles, then to a piece of corrugated plastic.

Using another propeller from the Model Aerodrome in Seaside Road, Eastbourne, James took the remaining good solar panels from his action man conversion (some panels had not survived submersion and rough treatment) and put these on the roof.  A solar motor was slung under the parasol roof, giving enough clearance for the propeller and bingo, another floating test bed.

James attends Hawkes Farm School, Hailsham, East Sussex.  Teachers are now explaining about sustainability and pollution under the Agenda 21 programme.  James wants to be an astronaut.  His sister is building a Windmill, hoping she can make it generate electricity to sell to the National Grid.

 By thunder it works - but it's a bit slow - click picture for fast boat

The small air propeller is not generating much thrust, so James fitted a much larger one - seen below.  Even so it seems the boat could go faster.  The next thing to try is a water propeller.  But how can this boat be adapted?  See how a propshaft is fitted in the next phase of blackcurrant bottle boat.

A larger propeller is fitted but it's still slow
