This is a brief summary of the comments, ideas and lessons learned in the mid reviews on March 9th 2009.
-2 optional ways to deal with the electricity produced by human power:
A. Storage in 'Main Local Batteries' - A battery for each activity zone (Advantages: 12 Volts DC power, the same electricity produced is actually used for the park's facilities. Disadvantages: loss of electricity due to heat&friction in the transfer between batteries and facilities)
B. Sell the electricity back to Con-Ed (obligatory for them to buy it- enforced by the law) and then get electricity for the park's facilities through the Con-Ed Grid. (Advantages: No switch between electricity sources, no energy loss for heat, friction, etc. Immediate output according to demand, use of 120V AC power - versatile facilities to be use in the park. Disadvantages: Use of 120V AC power with human, especially children facilities, no immediate direct sensation that electricity produced is the same being used for the facilities)
-Equipment for elders: Possible usage of the 'Hebop' mechanism with benches or park seats for people who can't use the sport-designated equipment of the 'Hebop'.
-Equipment set-up: In the set up and location of each activity zone, it is possible to provide activities for other family members - such as exercise activity (that generate energy) in the vicinity of the children playground. Think about the formation of each activity zone in relation to what are the desired results.
User immediate feedback:
Differential feedback- different feedback between different user-population (playgrounds, gyms, etc.). For children- Halo effect, spreads out the more they make an effort.(LEDs)
Electricity Cost Analysis:
Show viewers actual numbers - how much electricity a real park consumes monthly, how long children use each piece of equipment (merry go round, seesaw...). Make a comparison of how much electricity HeboPark would make in order to fulfill the actual demand.
Psychological and Social Aspects:
-Who earns the electricity the park consumes? (from who's bill is it deducted from?) the government? city of New York? Con-Ed?
-Who pays for the park construction and infrastructure? (the government? city of New York? Con-Ed? communities?)
-How do people feel when they get back the electricity produced by them? which is their preferred form of receiving it back? Do they need graphic feedback of the 'Electricity Story' - how it produced in the park, what is its route? etc.
Hebop- the pedaling station:
Investigate more forms and organic (mathematical-supported) shapes for the pedaling station form.
-Present a "cost analysis" like sheet: Contact Con-Ed and analyze 'the numbers' of actual existing parks + a comparison with the potential of Hebopark.
-Determine final form of the "Hebop".
-Determine the way to harvest the electricity (batteries/sell back to Con-Ed)
-Final proposals for user feedback for each activity zone.
-Continue building prototype for user testing.
