In the summertime, when the sky is a bright red and the weather is wet, windows are usually closed and windows are often covered with curtains.
In winter, when there are no cloud cover, the curtains can be left open, but they must be removed before the sun comes out.
That is not the case when it is a dark night and a window has been left open.
“That’s why we put our curtains on when we’re not using them,” says Michael Azzarello, director of the University of Leicester’s Institute of Atmospheric Sciences.
But the curtains have a tendency to get in the way of the sun, so they can be removed if they have to.
Azzariti is not a fan of using curtains, but he acknowledges the problem.
“The problem with using curtains is that they can get in your way,” he says.
“You can’t just take the curtains off, because they can make a whole lot of noise.”
The curtains that Azzadello and his colleagues have installed are the same kind that are currently in use around the UK, as well as in many other countries.
“We wanted to make sure that our curtains worked in the same way,” says Azzamello.
“There are two kinds of curtains, the standard ones that are made from the fabric of a jacket or coat, and the curtains that have a very low weight.”
To make sure the curtains didn’t interfere with the sun’s rays, the team has fitted the curtains with reflectors that were designed to reflect sunlight back towards the curtains.
But they also installed two other devices that allow the curtains to be removed when the sun is not shining.
The first device is a large-scale lens.
When the curtains are open, the lens will reflect sunlight directly back into the room.
But when the curtains aren’t closed, it will create a small “wave” that can reflect the sun back towards you.
This is an important part of the system, because sunlight can also get trapped between the curtain and the glass and can cause damage to the glass.
“It’s a very strong lens, so we wanted to ensure that it doesn’t interfere,” says Ajay Sharma, a PhD student at the University at Albany who designed the system.
A second device, which can be activated by the user, allows the curtains’ light to travel around the room in an arc, so that it reaches the sun and reflects it back at the curtains for the curtains themselves to see. “
This is one of the most important features of the curtains, that it reflects the sunlight, but it doesn�t create a shadow that can get trapped inside the glass.”
A second device, which can be activated by the user, allows the curtains’ light to travel around the room in an arc, so that it reaches the sun and reflects it back at the curtains for the curtains themselves to see.
When this happens, it creates a light that is even more powerful, but still leaves the curtains open for the sun to see, as it travels around the house.
“What we have is a system that has the capability to change the light that you get back into a very powerful system that can be switched on and off with a button,” says Sharma.
“In the same manner, the system can be turned on and disabled with a single button.”
In this case, the light can be directed to the curtains in the evening and off at night.
“Our goal was to find a way to switch off the curtains by changing the light intensity,” says Kumar, who is also at the university.
“If you want to have a little bit of shade and a little of privacy in your home, this is a very useful technology.”
In the next section, we will explore some of the other benefits of using outdoor curtains.
