Planet Paprika Proyect at Unidos!

Leave a comment

Last Saturday, I discovered Unidos association in Lille, France!


Its very active members already made a lot of solar energy projects in Latin America: solar showers in Bolivia, solar cookers in Peru and Chile, and solar lights soon. They fund their projects only with private donations, thanks to events that they organize in France, like for example football matches.


I had the opportunity to present Planet Paprika Proyect during this event organized in Macondo cafe in Lille. I also exchanged a lot about project management and solar technology with Unidos.




A very pleasant day!


Solar dryers at Alternatiba!

Leave a comment

On Saturday, September 12nd, I had the opportunity to present the 2 types of solar dryers we made in Normandy in public. I had a stand at Alternatiba village of Evreux (Normandy), where about 3000 visitors came besides rainy weather!



People were very interested in the 2 systems, they looked at the photos, read the pannels, wondered what there was inside the pots (dried fruit!)… And I could five them explanations and talked to them about the project in Peru.




The day was a great experience!

Undirect solar dryer

Here are the photos taken during the building of the undirect solar dryer with thermal solar pannel. Soon will be published more explanations about it!

  1. Put dried fruit into a bowl of water to rehydrate them.
  2. Mix eggs and sugar to obtain a fluffy mixture. Melt butter and add it to the preparation. Add baking powder and flour to obtain a thick mixture.
  3. Add dried fruit and some water used to rehydrate them. Mix the preparation.
  4. Put the dough into a cake dish.
  5. Melt small pieced chocolate in double boiler. Spread melted chocolate over the cake.

A solar dryer in the Alps!

Leave a comment

September 2014, I’m building another solar dryer in the Alps, South of France. The design is the same as the one in Normandy, but the use of recycled materials triggers once again the adaptation of the original structure designed by the Solare Brücke association. This 2sqm dryer didn’t cost anything to the producer, who managed to make order in his materials storage 😉


The producer wants to use his solar dryer for plants drying. So, he suggests to cover the part where we put the products to avoid direct exposure to the sun. It seems that this doesn’t have impact on temperatures (we couldn’t measure it).

The 5W solar pannel we used was recycled from an installation for electric fences. We first tested it on a 12V and 0,25A fan taken from a computer.

The plastic cover we used has already been used, so it’s quite fragile. To avoid plastic cover manipulation, we decided to change the inner access of the dryer. The air outlet of the dryer can now be opened just like a door with hinges. Little taps are used to close the access and a cotton material avoids insects penetration. So now the plastic cover is entirely fixed on the structure.


Loose products are placed on a rack raised so that air can flow on both sides. The producer noticed the benefits of nettle drying in September / October – when the plant is matured – to make nettle tea in March when it’s needed in the fields, to prepare next agricultural season.

The Planet Paprika Proyect website has changed! It has now a complete project description, from prototype building to results. It also presents a new project for which we are looking for volunteers and funds, so feel free to contact us!

Dried fruit!

Leave a comment

New season for solar dried fruit production has begun in Normandy! We started our tests on pears, apples, strawberries and cherries. Results are satisfying, particularly with apples and pears, and dried cherries are perfect to replace raisins! However, dried strawberries got a bad aspect and strange texture. Once rehydrated, we’ll have to taste them!
