Cost saving of snow-and-ice utilization by introducing innovative sheets, light tents and snow cannons

在多雪的寒冷地区，为清除积雪投入了大量的人力和费用。雪丘具有作为冷能源的潜力。他们可以通过规划储存和分配的应用，为提高日本能源自给率和粮食自给率做出贡献。为了大幅度降低冰雪利用中最大的问题——冰雪储存成本，本研究验证了创新床单和轻型帐篷的有效性。此外，为了扩大利用面积，进一步稳定能源供应，验证了利用室外冷空气产雪的雪炮引入效果高。

A great deal of labor and expenses are cast into removing the snow in the snowy cold districts. Snow mounds have a potential as the cold energy resources. They can contribute to the improvement of the Japanese energy self-sufficiency ratio and self-sufficient rate of food by planning the application to storage and distribution. For the purpose of large reduction of the snow-and-ice storage cost that was the biggest problem for the snow-and-ice utilization, this study demonstrated the effectiveness of innovative sheets and light tents. In addition, it was verified that the introduction effect of snow cannons which produce the snow by using the cold outdoor air was high aiming at the enlargement of the utilization area and further stabilization of the energy supply.
