Description:

The Sun Juicer is a parabolic solar cooker assembly kit. 

  •  It's extremely compact when not assembled, making it very convenient for storing in small spaces compared to other bulky parabolic solar cookers. 
  • It's light weight and volume make it particularly exceptional for transporting and shipping (individually or in bulk).
  •  Not only It is easy to assembly but it is completely manual, no tools are required. 
  • It's able to accomplish basic cooking needs, for one to two people at a time, fueled only by the energy of the sun.
  • It can use  a variety of pot and pans  without the need of special heat resistant plastic bags to contain them.
  • All of this that make it ideal for using in your backyard, camping, education, and to have stored away together with your emergency kit.

Background:  

I've always been fascinated with the many ways we can harness and take advantage of the sun's energy. The benefits of using solar cookers are being adopted throughout the world. The box or panel type are widely used due to their practicality and low cost. The parabolic styles are known to be more efficient, but in many cases bulky and expensive. I have tried to gather the advantages they all have to offer combined into one which is highly efficient, inexpensive, very compact and light weight. My experiences with a variety of computer design software allowed me to draft and model the initial designs. My skills in model making and fabrication gave me the ability to build a prototype and experiment with many materials. I diligently test and retested looking for design flaws that I was able to correct. After many designs and prototypes I finally came up with this patent pending design, that I proudly named The Sun Juice, since we'll all be juicing is the sun! Preliminary designs and prototypes.

Preliminary designs and concepts.

 Specifications:

Size : The Sun Juicer: 39” wide, 29 high, 16” depth 

Approximate gross weight : 635 gr = 1.4 lb

 Dish: 26” diameter , 7" depth 

 Kit size in bag: Approx. 19” x 8” x 1”

 Features:

The Sun Juicer is an extremely lightweight and compact solar cooker.

The parabolic dish is made out of a highly reflective heat resistant Mylar coated with aluminum oxide.  

It has a simple to assemble structure that supports the dish, and stove top, it will allow you to easily position align and adjust your solar cooker to the particular position of the sun through most of the day. Tips and guidelines will be provided in the manual.

The stove top allows you to use small and medium household lidded pots and pans (preferably black in color or as dark as possible).

Does not require special containers or heat resistant bags. 
The recommended maximum capacity of 3 lbs. the recomended pot or pan should not exceed 8" diameter.  
It comes with a simple instruction manual and user guide for building,  positioning, maintaining and basic care.

Uses:
The Sun Juicer can  boil, fry, grill, and steam, just like a stove top, for 1 to 2 people at a time. 
It takes approximately 35 minutes to boil 2 cups of water on a clear sunny day.

For example:

It fries 3 eggs in about 8 minutes.

There are other factors that will vary cooking times, such as time of year, time of day, weather conditions, and proper usage. It won't be as fast as as other cooking methods, but certainly cleaner and in many cases the only alternative at hand.

Besides cooking, The Sun Juicer, will allow you to light a fire in about 1 minute, and can also be used as a light projector.


Assembly:
One of the most unique qualities of The Sun Juicer is it's easy assembly method. It will allow basically anyone to have an affordable parabolic solar cooker with out the hassle of a big bulky  system.
The only tools needed to assemble The Sun Juicer kit, are your hands,  
It comes with a complete step by step manual that will guide you thought the assembly of  your solar cooker. Links to online videos with tutorials will be available as well.

The Team

 We are a husband and wife team. We have worked on a myriad of projects together.
 I'm Hannie Goldgewicht, a professional artist. I bring my organizational skills, business sense and expertise to Leo's design and technical abilities.
Leo Gotlibowski is the visionary behind this project. Besides designing and prototyping he will be involved in every aspect of the production. Together we have been very successful in bringing many projects to completion. Please check out my links to get a sampling of some of our joint projects.

 Production:

 All our working prototypes have been handmade and proved to be  successful and functional. They have been used and tested for over a year.  
  The Sun Juicer on a one on one basis. We have already 
  Since our first campaign we were planning on outsourcing most of the production. That meant minimum quantities and extensive tooling cost. In our quest to not give up with this project we tried an approach that would allows us to manufacture most of the components ourselves.We have since started  a small production and we are extremely happy and excited with the results. Now we do not need to rely on those third parties, so we can start with a smaller production and at the same time ask for a lower goal.  Your pledge will help us purchase the machinery need to do just that.  Of course eventually we will like to get to the point of  mass production. But for now,we just hope to get this rolling.



Funding
By pledging for  your very own Sun Juicer or one of our other great rewards , your support will help us  move forward with manufacturing The Sun Juicer. 
The funds will let us set up our first production run of Sun Juicers. Our goal will help us cover setup costs for producing the components, materials, hardware and packaging. 

This ongoing process will aid us not only to bring this project to fruition but hopefully to be just the first of many solar projects. We hope you will be a supporter of this new environmentally friendly technology. We are hoping to create awareness with a community of like minded people. Join us in this very worthwhile endeavor. We look forward to sharing with you up dates and new products, that are already on the drawing board, for years to come.
Besides pledging you can be apart of this movement by sharing in social media, talking about it with your friends, and spreading the word. Every little bit helps!

Fulfillment  and Timeline

- We are maintaining a realistic time-frame for scaling up production.
- Dividing production into batches: instead of trying to get all out by one shipping date, we'll start with smaller runs (for the limited edition and early birds), followed by two batches at a higher capacity. This will let us manage manufacturing and fulfillment at a manageable scale and pace.


September- Production of all components begin.
October- limited edition are ready to ship out. 
November - Early bird production is ready for packaging and shipping.

December- First Batch is ready for packaging and shipping.

January 2015 - Second batch is ready for packaging and shipping.

Safety an disclaimer:
This model and size of The Sun Juicer is most useful in warmer climates.
Weather conditions like temperature will influence how and what you cook. The user guide will contain tips and suggestions as to how maximize its potential. We can not guaranty that The Sun Juicer will work at its full potential in cold weather. Its been tested at 50 degrees Fahrenheit with excellent results. 
It is not intended to be used in windy conditions. But it can be used  if placed in a secluded area shielded from the wind.

We have designed the sun juicer to be as safe as possible but like anything that involves the sun rays, some precautions and care should be taken into considerations. Do NOT look directly at the sun or at its reflected rays. Use of eye protection is advised. 
The Sun Juicer was designed to reflect the sun rays into a specific focal point and to diminish the amount of sun rays that diverge. Always take precautions to not look directly into to focal point. 
When cooking, even though no fire is present, the stove top will reach extremely high temperatures. Take the same precautions and care as you would with any other cooking method.

All the prototypes shown in the video and photos are fully functional and tested. Details and materials used may change in the final development and manufacturing.

The future of the Sun Juicer
As mentioned before, the design of the Sun Juicer was conceived to have the especial characteristics needed while maintaining a low cost. Ultimately an increase in production quantities will help  lower these costs even more, making it more accessible to people around the world. 

This is what I dream of. We hope that with your help and support  we will be able to kick start this dream of making parabolic solar cooking affordable to all and to offer The Sun Juicer to world organizations that have the possibility of disturbing it where it is most needed.

Thank you for your attention, interest, and support. I look forward to sharing this journey with you!


Risks and challenges

The biggest challenge I face in bringing this project to fulfillment would be delays in the shipment of the materials or machines needed.
The Sun Juicer has few components so it is not necessary to deal with many distributors. In any case we have lined up various suppliers.

I see no mayor problems in production and deadlines, but to be on the safe side, I am allowing enough time to complete the initial production run.

I have contemplated different technical and manufacturing approaches to tackle issues that we might come across as well as changes that might improve the final product. These different approaches will be decided depending on the quantity to be produced.
