Roquetinho is an application of the Batch Rocket design, that has proven to be outstanding efficient and incredibly clean. Initially it was meant for Portugal, where wood burning is a common form of space heating but technology is poor – with many inefficient and dirty wood burning appliances.

But also in other countries the Roquetinho design is very well applicable. It is relatively simple, cheap, and very efficient. The hope is to make Batch Rocket technology available to as many people as possible and for the lowest possible price.
