Product Information

Full details

This Solar Radiometer is designed for those who appreciate unique desk decor and a visual demonstration of physics. Its key benefit is providing a captivating display as it spins in sunlight, making it an excellent conversation starter or gift. A primary caveat is its fragile glass construction, requiring careful handling. The product features rotating vanes activated by light energy, housed within a glass bulb, and comes in a yellow color family.

FAQs

How does the Solar Radiometer work?

It works based on the principle of radiative pressure. When light strikes the dark sides of the vanes, they absorb more energy and heat up more than the lighter sides. This causes air molecules near the dark vanes to be expelled faster, creating a thrust that makes the vanes spin. The black vanes are pushed away from the light source.

What is the size of the Solar Radiometer?

The approximate size is 14cm x 7.5cm.

Is this product suitable for children?

The product is recommended for ages 14 and over due to its glass construction and the care required. It is not a toy.

What type of light is best for making it spin?

Direct sunlight provides the best results. Strong artificial light sources like incandescent or halogen lamps also work well, but LEDs may not be sufficient unless very powerful.

Can I clean the inside of the glass?

The glass bulb is sealed, and the inside should not be opened or cleaned. External cleaning with a soft cloth is sufficient.

What does the yellow color refer to?

The yellow color family refers to the overall aesthetic of the product, likely the color of the base or accents, as the main functional part is the clear glass bulb and the vanes.

Troubleshooting

Vanes are not rotating.

Ensure the radiometer is placed in sufficient light. Direct sunlight or a strong lamp is usually required. Check that the vanes are not obstructed or stuck.

Rotation is very slow or erratic.

Light intensity may be too low. Try moving the radiometer to a brighter location. Uneven light distribution can also cause erratic spinning.

The glass bulb appears cracked or broken.

If the glass is damaged, discontinue use immediately due to the risk of injury from broken glass. Contact the vendor for a replacement if applicable.

Pros and Cons

Pros

  • Visually demonstrates physics principles in action.
  • Adds a unique and engaging decorative element to any space.
  • Serves as an excellent conversation starter.
  • Makes for an unusual and memorable gift.

Cons

  • Made of glass and therefore fragile; requires careful handling.
  • Performance is dependent on light intensity; may not spin in low light conditions.
  • Not suitable for young children due to breakability and age recommendation (14+).
  • Does not serve a practical function beyond demonstration and decoration.

Setup, Compatibility & Care

Setup: No assembly is required. Simply place the Solar Radiometer on a stable, level surface where it can receive adequate light.

Compatibility: This device is compatible with any light source, but performs best with direct sunlight or strong, focused artificial light. It is not electronic and requires no power source other than light.

Care:

  1. Handle with extreme care as the glass bulb is fragile.
  2. Clean the exterior glass surface gently with a soft, dry or slightly damp cloth. Avoid harsh chemicals or abrasive materials.
  3. Do not expose to extreme temperatures or direct impact.
