Transparent Radiometer

Product Description

The transparent radiometer, also known as the light mill, was invented in 1873 by chemist Sir William Crookes. While weighing minute quantities of samples in a partially evacuated glass chamber this celebrated British chemist observed the scales moved when exposed to sunlight. With some refinement the vanes were made to rotate using this remarkable photoelectric effect.

The radiometer itself consists of an airtight glass bubble with vanes inside which are mounted on a spindle in a partial vacuum. The vanes themselves are black on one side and polished metal on the reverse.

When you expose the radiometer to light from the sun intense artificial light, the vanes rotate. The reason for the rotation has been a cause of much scientific debate. However you will be captivated by this device, watching as it spins with varying intensity depending upon the brightness of the light that falls upon it.

Designer’s Atelier

Originally a scholar devoted to the study of philosophy and history she paid little heed to her childhood habit of rearranging objects let alone envisioning a future as an award-winning designer with a devoted international clientele. When her years of study left her restless with their lack of practical application a chance distraction of redesigning an old house was nothing short of a great awakening. She realized that interior design was a living philosophy noting that the arrangement style and colours of a room has a direct influence on its inhabitants. What she had overlooked as a compulsive habit now transformed into an all consuming passion revealing an almost uncanny instinct for balance and a brave use of texture and materials that others were quick to take note of. After a stint working for the famed Andrew Martin design team she procured a coveted internship with interiors icon Kelly Hoppen. With the quiet assurance one only sees in those who have found their life’s mission Dagmar had a growing client base before even finishing her design course. Awards began to pile up. She attracted the attention of Sir Terence Conran and Philippe Starck who judged her worthy of second place in the One to Watch Mydeco competition which aimed to discover the UK’s most promising designers. BIDA Design Review magazine showcased her as runner up in the Il Tempo Abitare competition. Most recently she was one of three winners in Homes & Gardens magazine’s competition sponsored by renowned interiors brand Sanderson in their search for a designer who could bring English style to a 21st Century interior. Working both residentially and commercially and with a product line that sells internationally Dagmar prides herself on her approachable manner with clients and has committed herself to creating design experiences that work from the inside out to restore one’s energy and reflect one’s own personality lifestyle and good health over following any trend.
