SunPram is a floating mobile platform for solar panels.

The idea is to make use of the microporosity of the Nike Grind material and make a floating structure upon which solar panels can be placed.

Solar cell parks on land are well-known. The problem is that they occupy land. 

Floating Solar panel parks are gaining popularity as they don't take up land. However, they are not mobile as they are fixed with anchors.


Large floating structures in alternative materials are well-known. During WW2, pykrete, a mixture of water and woodpulp that when frozen was stronger than plain ice, was invented. 

Developed as part of Project Habakkuk, pykrete was slower-melting than ice and would not sink. The idea was to use the material to make a floating structure to be used as an aircraft carrier.

We propose to make a large reinforced structure based on Nike Grind granulate being held together by a binder (similar to concrete). 

The resulting SunPram can be towed to any location where extra electricity capacity is needed (like after the storm in Puerto Rico in 2017). It's plug'n'play and batteries in the bow.

Obviously, a flatter version of SunPram can be used for stationary floating solar cell parks.

Which Nike Grind materials will your idea utilize?

  • Rubber Outsoles
  • Rubber Flashings
  • Rubber Granulate
  • EVA Foam Injection Scraps
  • EVA Foam Flashings
  • EVA Foam Sheets & Blocks
  • EVA Foam Components
  • Laminated EVA Foam
  • Laminated PU Foam
  • Mixed Apparel Textile
  • Mixed Footwear Textile
  • Footwear Fiber "Fluff"
  • Full Grain Leather Scraps
  • Split Leather Scraps Coated
  • Synthetic Leather

How specifically will these materials be incorporated into your solution?

We can use all Nike Grind types with some degree of closed porosity (total density lighter than water)! The Nike Grind can be applied in layers using a combination of technology from sprayed concrete (so-called shotcrete) and insulation of double walls with e.g. stone wool. The binder and the Nike Grind are mixed in the last minute and then sprayed on in layers or on an existing structure. Some process redesign and optimization of equipment for the manufacture of large structures such as SunPram is expected.

Please include a visual (can be either 2D or 3D) representation/prototype of your concept. (required)

What is the current stage of development of your idea?

  • Research & Early Testing

Describe your target market. Who will benefit from your product?

The market presently use mobile containerized diesel or gas powered generators to generate electricity. Consumers will benefit from not burning fossil fuels. Further, the problems with particle emissions and noise are eliminated.

How will you scale your idea? Please describe in detail your plan to scale your concept.

Build a small SunPram and learn from that. Then build a bigger pram and learn from that. The biggest obstacle is to get someone to patiently finance "moon shots".

How is your idea innovative?

The concept combines different existing technologies in a new way.

Tell us about yourself and your team. What is your background and experience?

An individual problem-solver.

Please describe how becoming a Top Idea will support the growth of your concept.

We hope that Phil will call Elon.

Hi SunPram ,

Great to hear from you! Could you please provide more content for the submission question, "How specifically will these materials be incorporated into your solution?" How might you begin to turn the raw Nike Grind materials into your final product? What might that process look like step-by-step?

Additionally, to be eligible to advance on to the next phase of the Challenge, please complete the entire submission form. We see you have multiple questions that are unanswered and want to sure you are set up for success.

With the deadline fast-approaching at 5:00 p.m. Pacific Time, please ensure all of your final updates are completed by then.

Excited to learn more!
