We seek ideas for capture, transfer, switching and storage of electrical lighting discharges as a potential alternative energy source. The four subsystems will be judged separately and a portion of the award will be dedicated to each subsystem. Solvers are eligible to address one or more of the subsystems for the award on each. This is an Ideation Challenge so your creativity and experience qualify you to participate in this Challenge. Responses are expected to be about 2-3 written pages not including figures, however there is no strict limit on length. Read more.

The Rockefeller Foundation is providing support to this Seeker for the design of a low cost water treatment system based on solar radiation and titanium dioxide (TiO₂). It is part of the Global Giveback Innovation Challenge Set. A prototype design will be required using known proven technology supplied by the Seeker. Read More.

Challenge Reward: $15,000 USD

The Rockefeller Foundation is providing support to this Seeker for the design of a new rainwater harvesting storage tank for use in a wetland Region in India. It is part of the Global Giveback Innovation Challenge Set. The tank needs to be affordable by the local people and have a capacity of 6000 liters. High water table, flooding, differential settlement and acidic soil are just some of the issues to be overcome with the proper design. Read More.

NASA is looking for a novel engineering mechanism for a compact, effective aerobic and resistive exercise device. They are not looking for you to design the complete device, but just the engineering mechanism that could deliver the proper resistive and aerobic motions for exercises in space under very limited or zero gravity. There are very specific size and space requirements. Read More.

As we go deeper into space and spend more time on the International Space Station (ISS), missions become longer, requiring packaged food to be stored for longer periods of time with even greater restrictions on size, weight and waste disposal. New food packaging technologies are needed that have adequate oxygen and water barrier properties to maintain the foods' quality over a 3 - 5 year shelf life. The new packaging must have improved barrier properties, remain lightweight and be compatible to sterilization processes and proper disposal. Read More.
