The first big slide took place in a theatre in Paris in the 1790s after the Revolution. After waiting for a few minutes in total darkness with the eerie background music of a glass harmonica, the audience begins to see various shapes appear in the sky, which appear to be light and shadow patterns floating and gliding through the air. These ghosts are pale and lifelike, and can talk, shout, and cry. One of the ghosts is a bleeding nun, first coming closer and then gradually moving away. Later slides involve the ghosts of recently deceased public figures, who are said to have been summoned by the power of science. Because that's how these shows are marketed: it's an intersection between science and religion, faith and enlightenment. They're scary, but they're also hilarious.
Glass is probably the most overlooked material in history. It is essential to our lives, even more important than plastic. To me, a world without glass is even harder to imagine than a terraforming Mars (which most scientists agree is practically impossible). Without this miracle all around us, you wouldn't be able to use a touch-screen phone, turn on a glass light, see from a window, wear glasses, or enjoy a drink from a glass bottle on your bedside table. You won't be able to receive email, phone calls or access the Internet.
In recent years, the state has introduced a number of policies to encourage the development and innovation of the photovoltaic glass industry. Industrial policies such as Notice on carrying out the fourth batch of smart photovoltaic Pilot Demonstration Activities, Guiding Opinions on Promoting the development of the energy electronics Industry, Notice on promoting the coordinated development of the photovoltaic industrial chain Supply chain, Matters related to promoting the healthy development of the photovoltaic industrial chain, and Action Plan for Accelerating the green and low-carbon Innovation and Development of electric power Equipment provide clarity for the development of the photovoltaic glass industry. The broad market prospect provides a good production and operation environment for enterprises.
