US-based designer, Michael Jantzen has unveiled his Solar Winds Coffee House structure, which is to be powered by energy harnessed from the sun and wind.
The structure will feature a huge vertical axis wind turbine mounted on top, along with an array of photovoltaic cells.
The coffee house will house a geothermal heat pump which ensures structural temperature control and an option to gather rainwater.
The central cylindrical portion of the cafe will have a large skylight and natural ventilation system and will feature a central counter and serving area with tables and seating around the perimeter.
The north-facing deck will be shaded by a large undulating roof made of seven large ribbon-like canopies and will feature additional tables and seating.
The structure will be constructed from sustainable materials, but as yet no location has been named.
