What is the improvement made to the solar concentrator of terrace ?
The innovation allows the concentrator be accessible from inside the building, which was not possible before.
How is the concentrator integrated to the building ?
In climates without cold season, the cooking plan is placed ahead of a south-facing window. When the window is closed, the use of solar energy does not heat the house.

And for cold weather climates ?
The cooking plan is protected by a bay window, then it is inside the building, and accessible whatever the weather.
Below, two views of the bay window from outside and from inside.
What is the interest of this innovation ?
The concentration of solar radiation allows the use of solar energy for cooking, with a high energy efficiency, while using a simple technology, easy to maintain and recycle, unlike the use of solar cells, with low efficiency, with high technology and very expensive.
When there's no need to cooking, the concentrated solar energy can be used to heat the room or a hot water tank...
It is in areas with regular sunshine that this technique is most effective.
A possible construction technology is similar to that of parabolic satellite antennas used for television: a stamped sheet metal, motor axes controlled by an electronic card.
Whatever the region, cooking directly on solar energy represents a strong user experience, a bit like using direct fire in a barbecue.
