reflector

Their innovative method includes incorporating artificial ground reflectors, a simple yet powerful enhancement.

The team engineered a series of these 3D reflectors strung together to form a "tunable transmission line."

Not only do they produce precipitation and provide shade from the sun, they also act as large reflectors that prevent the radiation of heat from the Earth -- commonly known as the greenhouse effect.

Snow and ice are good reflectors of the sun's energy hitting the Earth's surface and this helps to keep the Earth cooler.

Using a reflector and colored gels, I captured Storm in front of the textured paper, creating this image.
