INTRODUCING now in 2016 by SUNplicity, LIBERTAD400 the Portable Solar Cooker by Alain BIVAS (France)

Many years of solar cooking experience have led to this new concept which combines many unique features. 

All metallic, it may be the safest parabolic cooker, designed for surround non burning heat, will cook mostly on top and not stick to the pan.

The SUNplicity cooker takes just one minute to set up with no need for tools or special skills. It can be used anywhere, even on a small balcony. A coloured target makes alignment with the sun simple, and helps you to plan your cooking time. The shape of the mirrors allows you to safely leave your cooking unattended. The specific shape of this mirror can cook for almost 2 hours without turning the cooker. You can set the cooker slightly ahead of the sun's position, and let the sun to do the cooking. During cooking, the mirror remains cool. This prevents spills from drying and sticking – simply clean with a damp cloth or soft sponge.

A unique magnetic system allows the mirror to turn backwards in case of sudden wind, keeping the pot safely stable. We recommend that the base is weighed down with stones or bricks for extra stability. Unlike with other solar cookers, sunglasses are not required, as all cooking can be done from behind the cooker. The pot is safely centered away from the edges of the parabola. This protects children (and adults) by making it hard for them to touch anything hot by mistake. The cooker broils without burning, which makes tasty gourmet cooking very easy.

The cooker converts 65% to 72% of sunlight into heat which is very efficient (photovoltaics only convert 17.5%). The mirrors are made from the best quality aluminum layered with 2 nanolayers of ceramic for durability and maximum reflectivity (over 90%). All the elements are made of non-corrosive metals, which gives it a long lifespan. It is designed for intensive daily use. It can be stored away for a long time without deteriorating. The cooker is also designed with easy recycling in mind. 

When you've finished cooking, the SUNplicity cooker folds up just as quickly to a compact  50cm X 30cm X 4cm slim. This means it is highly portable, and can be stored in a much smaller space than other solar cookers. 

Specifications:  Weight: 5 lbs  Dimensions when folded: 50cm X 30 cm X 4 cm Dimensions when set up: 85cm in diameter Output: around 400 watts in full sunshine. Feeds: 2-3 people.
