Solar powered car vent lowers temp efficiently

There are still several scorching days of summer ahead.

A solar powered car ventilation system called Kulcar is hitting the U.S. market to cool things down inside vehicles nationally.

Sonray Technologies’ new Kulcar product offers an efficient dual chamber fan design that continuously circulates clean, fresh air and expels hazardous fumes from inside parked cars to keep them cooler. It is strictly solar operated and is capable of venting 45 cubic feet per minute, eliminating the uncomfortable hot air lurking in cars on sweltering days.

Kulcar’s convenient size and design allows it to be easil y mounted on car windows, providing a cooler and healthier vehicle and ride.

Kulcar completely replaces the air inside an average sized car every 90 seconds, reducing vehicle temperatures by up to 68 degrees and providing a more comfortable ride home from work or to pick up the kids. It’s beneficial both to human health and the environment, and is useful for conserving fuel and energy. Kulcar eliminates the need for temporary car fans, tinting, sunshades and sunlight reflectors.

Kulcar is now available on for around $100:

The solar powered car window fan reduces scorching in-car temperatures by up to 68 degrees.

About VOCs: There have been many studies of the types and levels of VOCs in established and new buildings in developed countries, summarised in recent reviews (Brown et al. 1994; Brown 1999). It has been commonly found that 100 or more VOCs can be detected in buildings, covering most compound types such as alkanes, aromatics, aldehydes, ketones and ethers. In established buildings, individual VOCs were generally at concentrations below 50 µg/m3, with most below 5 µg/m3. A measure of the total VOC (TVOC) quantity, total VOC (TVOC) defined as all VOCs in the boiling point range of 50–260°C (WHO 1989), had a mean of 200–1,100 µg/m3, reflecting the large number of VOCs present. VOC concentrations were much higher in new buildings, with TVOC concentrations up to 20,000–40,000 µg/m3 occurring in extreme cases. Recent measurements in some established and new Australian buildings (Brown 2000) have been consistent with these past findings.
