Briquettes made of invasive plants

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

Making a stove with a slab method

It is possible to make a ceramic Holey Roket stove rolling out clay in a slab form; a thick layer of clay wrapped around the pipe used for making briquettes. It is a very clean and fast method, especially if you are not used to sculpt with clay. You will need: pipes, cut in 45 degrees, 1pc 30cm – height and 1pc 20cm – length … Continue reading Making a stove with a slab method

Making briquettes in Teren

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

Reinforce the stove with a wire

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

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

Mrs. Chizenga from Malawi

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

Great progress in Philippines

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

Metal Holey Roket stoves in Chad

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

Nguvu Stove

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 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

Research, WWF Finland

Our research in cooking stoves issues was initiated in 2003 by World Wildlife Fund for nature (WWF) Finland as a collaborative project with the Product and Strategic Design Department of University of Art and Design in Helsinki. The project research was a collective effort by 5 international students, Heidi (Norway), Dan (Romania), Duncan (UK), Terro (Finland), Rok (Slovenia) and supervised by Simo Puintila (Finland). Our … Continue reading Research, WWF Finland
