What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Building on the success of the Silver Balloon Solar Cooker and Solar Balloon Energy Kit, we have developed the Silver Balloon Solar 2.0. Its new quick inflate and deflate valve makes the Silver Balloon Solar 2.0 more convenient and user friendly than ever. It is an ultra-light weight, ultra-compact, ultra-portable, high efficiency, and cost-effective solar energy product now with quick inflation and quick deflation features.

At under six ounces, the Silver Balloon Solar 2.0 is perfect for backpacking and camping. Its compact size allows you to stow it easily in a glove box, bug out bag, or even your pocket.

Silver Balloon Solar 2.0 can generate temperatures approaching 400°F making it ideal for cooking, heating, and water purification. 

In overcast conditions The Silver Balloon 2.0 can significantly increase the power output of PV panels. On a sunny day, it can bring one cup of water to boiling within 15 - 20 minutes.

 

Key advantages:

Ultra-light, Ultra-compact, Ultra-portable.

Easily stores in a backpack, boat, RV, or glove box.

Durable 21st Century laminated Mylar construction .

No emissions or pollutants.

No fire hazard.

Efficiently concentrates sunlight.

Zero carbon footprint.

Multi-functional: cooking, heating, water purification, PV enhancing.

Cost effective and manageable to send large quantities to people in need or to a developing country.

HOW IT WORKS:

 

The compact Silver Balloon inflates to become a powerful optical concentrator. Because its design utilizes non-imaging optic principles, it creates no focal point at the exit. Sunlight is therefore concentrated into a small area, but not to a single point. This design generates significant heat without the risk of fire. All light collected in the larger end of the balloon is concentrated at incident angle of 2Φ which magnifies light at the small end of the balloon. The concentrated sunlight at the exit ranges from 4 to 10 times the intensity of the sunlight intake at the larger end of the balloon. The cookware, foods, or water at the small end of the balloon will be heated or cooked efficiently by the concentrated sunlight. 

The material, similar to Mylar, was specifically developed for this application.

Our Priorities Behind the Design:  

  • A vision to create an Ultra-light, Ultra-compact, and Ultra-portable solar energy system that can easily travel with you, and provide an efficient resource available in a crisis situation to provide safe water for drinking and warmth.
  • Create the best design and use the best materials. Based upon our research, the inflatable structure constructed from a specially developed plastic film is the most light weight, most efficient, most stable, and most cost-effective design.
  • We demanded that the finished product was efficient and fast. It must be capable of reaching high temperatures quickly. We understood we needed a mechanism to efficiently collect and concentrate sunlight. Our design funnels and concentrates sunlight 4X to 10X internally. The temperatures beneath the cooker can exceed 350°F (176°C) – a highly efficient heat for our target applications. It's easily capable of bringing one cup of water to boiling in 15 - 20 minutes on a sunny day.
  • Safety. The product needs to be absolutely safe with no fire hazard. Our non-imaging optical design (the funnel) concentrates sunlight to a small area, not a point. It will not start a fire. There is no concern about eye injury or sun burn.
  • Stable in windy conditions. The three dimensional inflatable design is very stable in windy conditions because the wind is flowing around the balloon instead of penetrating the structure. We also provide two anchoring options to meet the challenge. 
  • User friendly. No assembly required – simply inflate and point in the direction of the sun to create energy. With the quick inflation and quick deflation features added to the Silver Balloon Solar 2.0, users can set up and take it down in just a few minutes.
  • Durability. Replace the weaknesses and vulnerabilities of cardboard solar cookers. Eliminate components made of glass or mirrors that can permanently break; No metal parts or screws to rust, bend, or break; No cardboard to crease or to succumb to moisture; No plastic to break or plastic coating to ruin the taste of your food. A system that is easily repairable if the need arises.

SCHEDULE

1/1 - 3/31/2017, Product design. Prototype.

4/1 - 4/30/2017, Develop new tooling. Sourcing materials and parts.

5/1 - 5/31/2017, Initial production.

6/1 - 6/25/2017, Testing. Make adjustment as needed.

6/26/2017 -   Start to send out rewards.

History:

  • We tried to use cardboard to make a solar concentrator. The material is not very durable.
  • We tried to use reflective plastic foam. It is very difficult to stabilize the structure.

We tried to design a pop-up concentrator. It is not very light weight, compact, and efficient. More importantly, it not only funnels and concentrates sunlight, it funnels wind as well. It is difficult to stabilize in windy conditions.

  We have done many tests to optimize the inflatable design.

 

 

 

 

And finally we found the best combination of efficiency, durability, cost-effectiveness, and portability --- Silver Balloon Solar:

Now with your help, Silver Balloon Solar 2.0 will not only have the quick inflation and quick deflation feature, but also be much more user friendly.
