PROBLEM TO BE SOLVED: To obtain the heat of convergence of high temperature by a small- sized device. SOLUTION: The device is provided with a guiding means 46 for guiding the sunlight to a convergent lens 11 and, therefore, the convergent lens 11 can be installed near the ground. Thereby the whole device is easily made small in size and handling thereof is facilitated. Moreover, it is not the convergent lens 11 itself, but the guiding means 46, i.e., first and second plane mirrors 31 and 39, provided apart from the convergent lens 11 that is displaced in following the movement of the sun. Accordingly, the focus can always be set at the same point and thus the heat of convergence of high temperature can be obtained with case. |
