WHAT OTHERS ARE SAYING ABOUT GoSun:
- Tree Hugger - "It is absolutely brilliant for a number of reasons, and is going to change the way we think about solar cooking."
- Grist - "We’re usually pretty skeptical about Kickstarters, but we can’t resist fangirling a bit about this one."
- Inhabitat - "This uber awesome tube stove can cook delicious meals without using a lick of fuel – in just 20 minutes."
Fast: Cooks a meal in as little as 20 minutes, utilizing every drop of sunshine
Portable: Pre-assembled package, deploy in seconds, weighing less than 4lbs
Versatile: Cook what you want and how you want. Bake, boil and fry; if there's sun, you're good to go.
Fuel Free and Clean: No burning charcoal embers to dispose of, no open flame to worry about. When you are done cooking, just fold up your GoSun and go.
Summer or Winter: If there is sunlight, you are cooking, even after a snow; plus, the wind won't steal your heat
Keeps Food Hot For Hours: Our evacuated tube technology is in essence a giant thermos. This means that when spotty clouds arrive, the tube will remain hot and steadily cook between sun-breaks. Plus, it keeps your brownies warm for hours until a late night snack.
Designed for simplicity, durability, and mobility, the GoSun offers a convenient, user friendly package for our fast paced lives. The GoSun is as simple in principle as it is powerful, effectively retaining 80-90% of all sunlight that is caught in its footprint. The technology relies on the principles of parabolic reflection, evacuation (for its insulating value) and the Greenhouse effect, to make the most advanced solar cooking device to date.
The GoSun will passively work its magic whenever the sun is shining. Water can be heated and hot meals can be prepared with a little patience even on the coldest winter day. A vacuum between two layers of tough glass prevents the outside ambient temperature from transferring into the inner cooking zone.

How to use the GoSun (45 second video)
Why solar cooking?
Traditional grilling is a lengthy, tedious process involving dirty and bulky equipment. Grills are rarely portable and, when they are, they typically involve handling extremely hot and messy equipment. Nothing in today’s market is eco‐friendly, efficient, innovative or stylish. The existing solar ovens are insufficient for today’s fast- paced lifestyle; they are too big, too slow and not user friendly.
That is why we developed the GoSun Stove!
Our analysis comparing the GoSunStove to portable and stationary propane grills, charcoal grills and camping stoves shows the GoSunStove ranking most desirable based on capacity, ease of use, cost, speed, style, safety, and versatility.

What we will do with the money:
We are a perfect project for KickStarter, because we honestly need this money to set up production, thus meeting minimum order quantities. We've put a ton of time and money in at this point and we're prepared for the exciting road ahead. Your backing gives us what we need to put the gears in motion.
Tools, Labor, Materials and Shipping: 77% of funds To bring you the GoSun Stove at a reasonable price, we are producing in China - where over 90% of the world's evacuated tubes originate. We're using high quality materials and tooling up with expensive jigs, dies and formers. Adam Moser, our Chinese Liaison, is committed to working with our experienced manufacturer who respects both the product, their employees and the environment.
Empowerment Program: 11.5% of funds We are committed to empowering others with our game changing technology. In coordination with a number of international partners (including Sonlight Power, Friends of Belle Riviere, Global Alliance for Clean Cookstoves) we aim to first educate, then provide a version of the GoSun especially built for the needs of the developing world. The GoSun Empowerment Program is committed to spreading this technology in a socially, environmentally, and financially sustainable way.
Market Development: 7.5% of funds There is a great opportunity for this innovative cooking technology but we will have to get the GoSun in front of people to share the light. Barriers to this new school solar cooking such as recipe modification and conforming to a tubular shape will have to be addressed through our media and on-the-ground presence. We'll be attending events, producing videos, gathering data, tackling problems and training GoSun Ambassadors to facilitate the switch to cooking with the sun.
Educational Material: 4% of funds The children are the future and so is renewable energy. We are going to develop products and curriculum to meet national educational standards for classrooms - 3rd through 8th grade.

Social and Environmental Benefits:
- Gender Equality and Women's Rights - less time and resources spent gathering fuel and making fires, increasing time for education and development
- Environmental Sustainability - by reducing the need for wood and charcoal, the GoSun will slow deforestation, soil loss, desertification
- Indoor Air Quality - by eliminating much of the need for indoor cooking fires, the GoSun will reduce smoke inhalation, the second leading cause of death globally
- Renewable Energy Access and Education - the GoSun is often the foot-in-the-door for a more solar fueled life
- Energy Security - off-the-grid, self reliance, independence
- No Child Left Inside - getting outdoors to stop Nature Deficiency Disorder
Where are we now:
The GoSun team has created over 30 prototypes over the last few years of development; most have been put to the test and critiqued by peers. We have demoed the GoSun Stove to several large gatherings (Bonnaroo Music and Arts Festival, Ingenuity Fest, Hacker Faire, etc.) in front of thousands of people; many whom ask "how much?" and "where can I buy one?"
We've been building the GoSun in small quantities by hand, and we cannot keep up with the interest. Recently having developed our best designed and replicable model, we've developed relationships with a manufacturer in China. We are ready to pull the trigger on our first production run and will be boarding a plane to China directly after this KickStarter. While there we will set up quality control and assembly operations.
STRETCH GOALS: For all backers purchasing a GoSun Stove or better once funding goals are met - Please share to make these a reality!
For the FINAL 48 HOURS of this campaign we will DOUBLE the amount of GoSun Stoves for the Empowerment Program = We Sell 5 - Then Gift 2!! Watch the Video (90 seconds)

THANK YOU FOR GIVING US THE GO !!!
Risks and challenges
We may have to work through some kinks in the international shipping department. Costs are variable, so we'll do our best to communicate with you regarding customs, delivery dates, and additional expenses that may apply.
We are sending a glass tube via standard shipping methods and we could have issues with damages. The tubes are made of a tough glass and we are designing a sturdy cardboard box to handle the dings in route to you. If your tube breaks, we will send you a new one with minimal S/H fee.
We've built over 30 prototypes by hand so we're very familiar with the process, materials and tools needed. We don't anticipate problems with our manufacturing partners, but we will inspect and perform quality control measures before the product reaches you.
When working with people in need, we will have to carefully transfer this new cooking technology. The GoSun Stove is very new and we have proven its performance. Along with our non-profit partners, we will work to educate and integrate this technology where the market is interested and capable.
No. Thanks for the vacuum between two layers of borosilicate glass, the outside will stay cool while the inside is blazing hot. This enables the user to move or adjust the tube at any time.
All of our GoSun products come with an appropriately sized cleaning scrubby to make it easy to remove food residue or grease from the evacuated tube cooking chamber. Keep in mind, most of the mess stays within the cooking tray which is very easy to clean anywhere. As long as you haven't made a major recipe error, the GoSun does not need to be cleaned after each use.
Yes, however the MINI was designed to be a testing device and the stand does not adjust for vertical orientation. You should be able to tilt it onto of rock or book very easily.
We have thoroughly tested the GoSun in all kinds of environments and conditions. We typically travel with an infrared temp. sensor and keep notes with a time stamp. If it is not humid, the sun at high-noon in the summer is about as hot as it gets, it doesn't matter where you are (below 40° N Lat). We've recorded temperature slightly above 700°F with an empty tube!! The 550°F cooking temp was recorded with a wired thermistor while roasting almonds.
Our intl. shipping costs are being examined and we hope to have a more specific cost for each continent. Shipping costs drop when the number of units increases, so please share our campaign with your friends.
During this initial phase of the Empowerment Program we plan to conduct several user-centered participatory design workshops in the developing world to hear directly from the market affected. We plan to create a GoSun Stove that is built of cheaper, more readily available materials using regional resources. This method should enable us to make the GoSun Stove significantly less expensive for these markets.
