| 中文简介: |  建筑物的供暖，通风和空调约占全球能耗的15％，但是由于窗户效率低下，与建筑物相关的能源损失了约20％。与生产和使用这种能源有关的温室气体排放量极大地促进了气候变化。有解决这个难题的方法吗？从与通过窗户损失能量有关的物理原理开始，我们将描述我们可见的透明，红外反射，热超绝热材料的发展，这些材料可以替代或翻新低效率的住宅和商业建筑的窗玻璃。通过许多演示，我们将讨论细菌如何辅助这种异常透明的透明气凝胶的生产，以及以食品工业和啤酒麦芽汁为废料的原材料，从而使这种智能窗户的价格非常低廉。 |
| 课程简介: | Heating, ventilation, and air conditioning of buildings account for about 15% of the global energy consumption, but about 20% of this building-related energy is lost because of inefficient windows. Greenhouse emissions associated with producing and using this energy contribute substantially to climate change. Is there a solution to this challenging problem? Starting from the physical principles associated with energy loss through windows, we will describe our development of visibly transparent, infrared-reflecting, thermally super-insulating materials that may replace or retrofit the inefficient windowpanes of residential and commercial buildings. Using many demonstrations, we will discuss how production of such unusual transparent aerogels is aided by bacteria, with the source materials in the forms of waste of food industry and beer wort, to make such smart windows highly affordable. |
