Making reflector mirrors from spinning bubbles.

In summary, the conversation discusses the possibility of using a spinning technique to create parabolic shapes in space using liquid metal or bubbles. It also considers the challenges of using ordinary metal or water to create bubbles in a vacuum environment. Images were not part of the conversation.

I heard about a technique where mercury or some other liquid is spun in a dish until it assumes a parabolic shape. Would this work in space? Could a flat membrane of liquid metal do just as well? It could be liquified by an electric current and start out flat like soapy water in a bubble wand.

If we then spun the ring and accelerated the whole thing along at 1 g to simulate gravity could it assume a parabolic shape? If so then switching of the electric current could preserve it as it cools and solidifies. I'm wondering if this might also work with spinning bubbles. Couldn't we then make incredibly thin yet huge reflector mirrors in space well beyond the influence of gravity?

Ordinary metal might not be elastic enough to make bubbles out of. Water isn't flexible enough to hold the air. It requires soap before a thin film of the liquid can be made to surround a pocket of air. In space there is no air at all so bubbles might only form in a pressurised cabin area. I don't know if a bubble could hold shape with air inside it and vacuum outside but would be interested in knowing.

Why can't I post images?
 

FAQ: Making reflector mirrors from spinning bubbles.

What is the purpose of making reflector mirrors from spinning bubbles?

The purpose of making reflector mirrors from spinning bubbles is to create a lightweight and highly reflective surface that can be used in a variety of applications, such as solar panels, telescopes, and laser reflectors.

How are the bubbles spun to create the mirror surface?

The bubbles are spun by using a specialized machine that generates a thin film of soap solution and spins it at high speeds. As the soap film rotates, it forms a spherical shape and the surface tension causes it to become highly reflective.

Are these reflector mirrors durable?

Yes, these reflector mirrors are very durable. The soap film used to create the mirror surface is incredibly thin and lightweight, making it resistant to damage. Additionally, the spinning motion helps to strengthen the surface tension, making it more durable.

What are the advantages of using spinning bubble reflector mirrors?

One of the main advantages of using spinning bubble reflector mirrors is their high reflectivity. These mirrors can reflect up to 99% of light, making them more efficient than traditional mirrors. They are also lightweight, low-cost, and can be easily produced in large quantities.

Are there any limitations to using these reflector mirrors?

One limitation of using spinning bubble reflector mirrors is that they can only reflect light in one direction, unlike traditional mirrors which can reflect light in multiple directions. This makes them more suitable for applications where unidirectional reflection is needed, such as solar panels.
