If you have invasive plants growing in your area, it is possible to change them to briquettes. These can be used for burning/cooking or for planting seeds – just fill the hole of the dry briquette with fresh soil and seed or young plant. In the urban space of Teren in Ljubljana, there are a couple of species of invasive plants: paulownia, fallopia and ailanthus/tree … Continue reading Briquettes made of invasive plants

We are lucky to have a place like the experimental playground Teren, launched by Prostorož, where we can develop projects that can not be done indoors or in other, more controlled spaces. We designed the original briquette press together with Richard Stanley from Legacy Foundation. They are responsible for many new briquette projects around the world. This one has been lying around making briquettes for … Continue reading Making briquettes in Teren

Heated with Holey biomass briquettes, the Hot Bench makes a cold wintery day a pleasant hanging-out time: warm up your behinds! Continue reading Briquette bench

Step by step guide of how to reinforce the stove with a soft wire. Continue reading Wired stove

You can ‘bake’ your clay stove at home – with making a so-called PIT FIRE – the original method for baking clay.  It dates back nearly 30,000 years ago. Your stoves need to be as dry as possible (to prevent cracking), so try to use any method on disposal to dry the clay properly. After the stoves have been drying indoors for 2 weeks, we laid … Continue reading Baking stoves in a pit fire

You can make your stove without any special tools (like plastic pipes). You need: clay (a mix of clay and sawdust and water) flat surface like wood cartboard paper your briquettes Start with making a paper template where you will form the stove. If you have 10cm briquettes, the stove should be 20cm wide and 30cm long. Form a 3-4cm thick clay base.      … Continue reading Making with no tools required

Tube stove is the most simple design for a briquette stove. It is not as efficient as Holey Roket, but still achieves a great output, using the hole of the briquette as an extension of the combustion chamber – the flames are centered to the middle of the pot just like with the Holey Roket. Making of the Tube Stove ..is even easier than the … Continue reading Tube Stove – can the simple work?

Metal pot holders can be made to help us use our stove longer and easier: – to prolong the life of the ceramic stoves – an angle of the top part provides a firmer hold – enables using smaller pots on the stove       Industrially made stoves often use cast-iron holder in one piece construction, but this is an alternative design that can be made … Continue reading Metal pot holders

Inexpensive brass wire was used to reinforce the ceramic stove construction. As we know, every ceramic liner breaks during cooking due to temperature differences in the monolith construction. Wire prevents the stove from falling apart and even if the stove is fully broken, it does not reduce the efficiency. The stove is now very durable and can be used for much longer time! Thank you … Continue reading Reinforce the stove with a wire

Some stoves tend to break during cooking due to big temperature differences in the stove’s body. There are some stoves already existing on the market that use the same principle of pre-cutting, so we tried to do it on the Holey Roket as well! Here are some basic steps of how to cut and bond the stove if you cut it AFTER the stove body … Continue reading Pre-cut the stove to avoid breaking

Joshua B. Guinto (Specialist, Sustainable Village Technologies, Tagsibol Development Enterprises, Phillipines) conducted a project to build a char-making stove, that can use briquettes or other convenient organic fuel. Please download a full report here : The Holey Roket Stove and BioChar Project     Objectives of the Project This project hopes to – Determine the technical performance of the stove prototype. – Determine its char … Continue reading Char making pocket

  Our friend, Mr. Joshua Guinto started distilling Barikolkol – wine from nipa plant, a kind of palm that grows in the murky mangrove forests. Barikolkol is the local name for the wine that comes from the sap of the nipa.                Joshua engaged with the wine distillers in the town of Vinzons. With a Japanese JICA volunteer, he … Continue reading Barikolkol wine distilation

Marcel Westdijk posted photos of introducing the briquette technology and Roket Stoves in Salima, Malawi; thank you Marcel! Here is a few words from him: I started designing a stove, based on Rok’s design, with a local tinsmith. I once used this stove with our nightguard, who cooked his sweet potatos and his tea on it, using two briquettes only. Normally it would have costed … Continue reading Mrs. Chizenga from Malawi

We’re happy to publish roket stoves by Joshua Guinto from Philippines! Amazing different designs from Joshua – here in the shape of a fish, truck and a human face!     Here is a printed advertisement for Holey Roket briquette stoves, please click to see a bigger image!   Here are some interesting words from Joshua: It is a mixture of clay that i have in stock. … Continue reading Great progress in Philippines

Thanks to Paul Rippey and Isaac Owor from Kampala in Uganda for providing these images! Continue reading Holey Roket in Kampala, Uganda

The Holey Roket stove type was adapted to the existing stove in Chad. First, drawings were sent with adjusted dimensions for burning briquettes. First prototype was made and was working with longer briquettes (app 6 inches in length). Briquette support was needed due to a larger combustion chamber and to allow the ashes falling in the box below. Due to lower-powered briquettes, more feeds were … Continue reading Metal Holey Roket stoves in Chad

In March, 2009, briquette research was pursued in Kampala, Uganda, as an extension to the Partnership for Clean Indoor Air (PCIA) conference. Ugandan biggest manufacturer of fuel-briquettes out of waste organic material Kampala Jelitone Suppliers Ltd. was in need for cooking-stove designs.   As briquettes resembled wood-fuel, more than any other existing fuel, we initially used the model of a Rocket stove design and modified … Continue reading Nguvu Stove

Mdula – a sustainable modular cooking stove solution for the local environment (Chembe village in Malawi), was developed in collaboration with World Wildlife Fund for nature (WWF) from Finland which initiated the briquette project in Malawi in 2001. Their work with introducing biomass broiquettes is addressing many critical environmental problems in LMNP (Lake Malawi National Park) like deforestation and soil erosion. The stove concept is … Continue reading Mdula Stove

It ranks with the very best of the ideas on display, solving a habitual problem in Malawi as part of a potential project for WWF (the World Wide Fund for Nature). It combines traditional basic methods with new design thinking at zero cost.
