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

在多雪的寒冷地区清除积雪需要投入大量的劳动力和费用。雪堆具有作为冷能资源的潜力。它们可以通过规划在储存和分配中的应用，为提高日本的能源自给率和粮食自给率做出贡献。为了大幅降低冰雪利用面临的最大问题--冰雪储存成本，本研究论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，验证了利用室外冷风产生积雪的雪炮引种效果较好。

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.
