The electrical engineers invented a plant that just needs a piece of land about the size of half a tennis court and sunny weather to toast up to 50kg of coffee an hour. It doesn't need any gas or electricity, but just sun rays concentrated by a set of mirrors on a rotating steel basket filled of fresh coffee grains.(AP Photo/Andrew Medichini)

The electrical engineers invented a plant that simply wants a piece of land in regards to the dimension of half a tennis courtroom and sunny climate to toast as much as 50kg of coffee an hour. It does not want any fuel or electrical energy, however simply solar rays concentrated by a set of mirrors on a rotating metal basket stuffed of contemporary coffee grains.(AP Photo/Andrew Medichini)
