What is the Hobogrill Project?
The Hobogrill is small, light weight, durable, portable, practical, environmentally friendly and highly effecient charcoal bbq cooking apparatus that can be made from recycled materials and is itself 100% recyclable. It operates on just 2 charcoal briquets (~90 grams) per side and you can cook on both sides.
There have been many models and prototypes. This project rewards the HG2 Series. Consisting of the HG2 and the HG2-Deluxe. Specifications listed below.
After full filling all the rewards, I will release instructions as open source under the Creative Commons 3.0 License for non-commercial purposes and requiring author attribution to the Hobogrill.org Project for anyone in the world to be able to build their own Hobogrill.

Environmentally Friendly Benefits
- Reduces landfill space by reducing/eliminating waste
- Minimizes carbon emissions by minimizing the fuel required to cook
- Increases awareness of recycling
1. An estimated 100 million steel cans (soup cans, coffee, vegetable, etc) are discarded every single day in the United States alone. This amounts to 36.5 billion cans per year. These cans are taking up massive volumes of landfill space. The hobogrill.org project teaches people how to safely and effectively extract the contents of the can and repurpose the can into a practical portable grill.
2. Most everytime someone uses a conventional charcoal grill, there is wasted charcoal. The charcoal is wasted in the form of unused heat from excess coals, or wasted in the form of impartially consumed charcoals which remain in the grill and are many times discarded in the ground or worse yet into a garbage can where it will end up taking valuable space in a landfill. The Hobogrill HG2 series eliminates this problem by only using the minumum amount of charcoal.
3. Free charcoal. If one is a true hobo, they understand the purpose of traveling light as well as economizing. Anyone can scavenge the grills at a public park for unburnt charcoals and use them to power the hobogrill.
My Journey to Create the Hobogrill
I wanted to create a portable camp stove that I could use while living full time out of a book bag. I recognize that hot food will be required to turn the romance of traveling the world into reality. The store-bought options were limited, heavy, bulky, and proved impractical for book bag living. So after a little brain storming and some experimentation, I came up with the Hobogrill HG1 Prototype in July of 2012.
After thoroughly testing the HG1-Prototype, cooking for my friends, wearing it around town, abusing it in marine environments (to test its durability), I wanted to make some modifications. I decided that the grill surface area and volume needed to be increased slightly to create a more satisfying portion size. Also, in the spirit of eliminating waste, I wanted to find a can with liquid contents so the contents could be extracted without damaging the can and the contents would still be fit for human consumption. Hence, the HG2 series was born.
The HG2 Series proved to be the perfect size. However, for the hardcore back pack bag traveler there was one convenience that had to be addressed still: quick access to sanitary storage for cooking and eating utensils as well as to manage the necessary accessories such as matches, condiments, etc (ie the "mess kit/tin"). I wanted the new addition to keep the grill lightweight and quickly and easily collapsible, and still be able to made from recycled materials. So I looked to the classic Altoids [sized] tin container and made it mount the side of the grill and collapse inside with hinges. The mess tin being a metal casing also helped protect the contents from rogue flames/heat. I refer to this model as the HG2-Deluxe.
I made a few accessories for the HG2-Deluxe model such as a folding fork and I cut the handle off a pastry brush for basting which are still under the testing phase and therefore will only be included in limited quantities with the HG2-Deluxe Super Kit at the $99 reward level.
What will the funds be used for?
The funds will be used to purchase resources (supplies to build the grills, make tooling/jigging, drill bits, cutting discs, etc) to full fill the rewards and as well maintain the website and content upon the full fillment of the rewards. A portion of the funds will go to facilitate further research and development.
Production Plan and Process:
The prototypes are currently made by hand which is a time consuming process. The only way to make all of grills to meet the reward deadlines is speed up the process through making jigs and special tooling which I have done already to speed up the manufacture of the prototypes. I have limited the quantity of the rewards and set conservative and realistic deadlines to ensure that they can be manufactured and shipped within the estimated delivery time.
I can further increase the manufacturing speed by using CNC automated equipment which would be a viable option provided the campaign were to reach a stretch goal.

Risks and challenges
The greatest challenge for this project is to streamline the production process enough to manufacture and deliver the rewards by the estimated deadline. I am well aware the logistics of fulfilling a great volume of rewards and dealing with potential delays from suppliers. To manage this I have set realistic/conservative estimated delivery dates.
Also, because of the unique nature of this project, there is another design challenge to be met for the how-to build a Hobogrill HG2 instructions to be usable by the widest range of people world wide. Due to the wide variety of resources available or unavailable (mainly tools/rivets/paper clips) to people in different parts of the world, some methods may be more feasible than others. The challenge here would be deciding which variations of making a hobogrill would help the most people while keeping a construction plan simple and straightforward for everyone else.Learn about accountability on Kickstarter
Upon the completion of the reward full fulfillment I will be releasing the plans for the Hobogrill HG2 series under the Creative Commons 3.0 BY-NC license. This means that it will require author attribution to the Hobogrill.org project as well as limited to noncommercial use/production of the grill.
I will be working quickly and diligently to deliver all of the backer rewards. So, hopefully, this date will likely be much sooner than originally anticipated.
The cans for the body of the grill will be new externally fresh cans. I will be repackaging the contents of the tin cans for later use and cleaning out the cans in preparation to make the Hobogrills.
There will be no aluminum cans used as I personally do not want to handle other people's used items where they may have directly put there mouth -- hence for sanitary purposes this part of the Hobogrill will be brand new made from aluminum sheet metal.
The bicycle inner tube carrying straps available for the Kickstarter Editions will be thoroughly cleaned and inspected before being transformed into carrying straps.
The hardwood dowel used for the handle will be brand new, as well as the bolts, rivets, hinges, nameplate and grill grate cooking surface.
The theoretical maximum amount of energy which can be harvested from 90 grams of charcoal is 1592BTU = 0.626hp = 466 watts.
These numbers were calculated from the United States Energy Information Administration (eia.gov) statistic of 19.51MBTU's per short ton of coal.
