There is a new front in the fight against climate change: the use of natural gas in commercial buildings and homes. While there is still much debate on the subject, the consequences could affect everything from heating systems in skyscrapers to stoves in suburban homes.
That is why more and more people are using rocket ovens nowadays. Most of our household energy requirements are for space heating and water heating or cooking. These make up a significant portion of our monthly consumption. Rocket ovens are an example of appropriate technologies that address these needs, cost you next to nothing to build, and just a few sticks to run. They are super-efficient and burn clean.
In some countries where wood fuel is scarce, rocket ovens help save lives. And they’re easy to build, too. You may not need it now but you can sure use one in times of emergency.
So why not make your own and reap the benefits of having a rocket oven?
