John Cocks, engineer comments... Effectiveness There are no test results to demonstrate that the system works. Magnets may not be necessary because water pressure should close the opening. The mechanism proposed to raise the platform to release water may not work. Durability Diagram indicates sturdy materials User-friendliness Concept is user-friendly Communication It's hard to read handwriting.   By Joe, Blake, Brandon and Baden John Cocks, engineer comments... EffectivenessThere are no test results to demonstrate that the system works. Magnets may not be strong enough to hold the hatch shut. The water might empty before the magnet can hold the hatch shut. Not clear how the foot pedal works. Durability Two legs would not be stable enough. User-friendliness Concept is good but the actual operation may prove challenging Communication It's hard to read handwriting.   John Cocks, engineer comments... Effectiveness There are no test results to demonstrate that the system works. Not clear how the foot pedal opens the tap. The filter will be effective for keeping out leaves and other material. Durability Insufficient detail to assess durabity. User-friendliness Concept is good but the actual operation may prove challenging. Communication It's hard to read handwriting. John Cocks, engineer comments... Effectiveness The whole idea is very good but the engineering of it may not work and there are no test results to demonstrate that the system works. Using a small amount of water at a time is a good concept. I'm not sure how the cup will tip or how the funnel system works. Durability Durable materials have been selected. User-friendliness Simple user-friendly idea is good but the actual operation may prove challenging Communication Good scheduling of materials.   Dr Norris comments...
