welcome to sundownloader
Sundownloader is an exciting new patented invention: a fixed mirror that always reflects light downwards. It has no need for lenses, moving parts, motors, wires, power, or controls. It is just a mirror, and it is always on when the sun is on.
The mirror’s curved face is precisely engineered to follow the curved path of the sun as it passes through the sky, and the patented curvature takes into account the differences between the short days of winter and the long mornings and evenings of summer.
No moving parts. No wires. No motors or controls. It is stationary, and it is always on.
No matter where the sun is in the sky, a sundownloader always reflects sunlight downwards. Any time, any day, any season
The mirror's curved face follows the curved path of the sun across the sky, and takes into account latitude, season and time
Australian Patent No. 2015376131. Further patent applications pending in many locations including Europe, USA, Canada, Russia, India, NZ & China. Priority date 09/01/15 WO 2016/110669
A Sundownloader directs sunlight to where it can be most useful. It moves where the sun shines from one place to another, reducing waste and improving efficiency, continuously at a running cost of zero
There is no net increase in solar energy absorbed by the earth and no net warming effect: the energy is simply moved to where you need it.
Public & private buildings
A Sundownloader brings an entirely new perspective on how light can be managed and directed effectively and efficiently. Architects continually look to include natural light in their designs. Light brings warmth and heat, which must be managed, and the sky also brings other kinds of weather, which must be controlled. Natural sunlight is often the casualty when these concerns conflict. Sundownloader resolves these conflicts
Greenhouses are usually orientated along a North-South axis, presenting their long sides to East and West. Industrial-scale greenhouses are built in blocks, and low-level light in the centre houses is obscured by plants in the outside houses
Sundownloaders could add a precious couple of hours of sunlight a day. If artificial lighting is used to enhance sunlight, then substantial savings might be possible
- Sundownloader enables growing of fruit, flowers and vegetables in dark corners or shadowed garden areas or courtyards
- Sundownloader can bring much needed sunlight to lighten dark basement apartments, extending sunlight intensity and lengthening available sunlight hours in the day
Alleys, courtyards, sunken gardens can all be enhanced by simple, inexpensive static sundownloaders
Our latest project
domestic residential courtyard, vancouver
A domestic block in Vancouver, which has minimal sunlight in the courtyard. Our virtual modelling has identified the optimum size and location for the Sundownloader to be positioned in order to achieve additional sunlight illuminating the courtyard.
The Sundownloader's curved face follows the curved path of the sun across the sky, and takes into account latitude, season and time
the future is HERE
The world needs greener sources of light and energy for a sustainable future. It needs cost effective methods to feed the ever increasing populations.
With Sundownloader, the future is here!
