Plant Observatory
of Weather Adaptability
for Resilience.

It is predicted that by 2050
the weather of London
will be like the weather
of Barcelona...

people could start growing the food they grow nowadays with their future predicted weather for 2050?

we could empower individuals and communities with data that could help them address climate change?

we could shorten the technological educational gap with low-cost DIY STEAM education tools?

we could teach and learn about climate change effects into our food systems in a more practical way?

POWAR is made under the philosophy of being a Distributed Design which can be easily manufactured in almost any maker space in the world by following the instructions. It is also open to collaborations, modifications and experimentations made by people connected to the project through different networks, in order to improve it, make it better and more accesible for the rest of the world.

All of the POWAR process is documented in this webpages and external resources, in order that everyone can access to the documentation, download it, and build it as they want. The more people that builds and improves the POWAR, the more benefit the project will generate to its community of users..

It has been created under a Creative Commons license "Attribution-NonCommercial-ShareAlike 4.0 International" (CC BY-NC-SA 4.0). Which permits the copy or modification of the prototype, while giving attribution, for non commercial use.


POWAR is made 70% out of sustainable wood and other materials like PLA, and basic electronic components. By being able to be manufactured locally, with mostly local materials, POWAR drastically reduces the carbon footprint of its production. This also has a reduction in transport and materials cost. Also, in the future it can be adapted to be solar powered and to feed the plants with rain water.
