A solar chimney or photovoltaic-powered fan can be used to exhaust undesired heat and draw in cooler, dehumidified air that has passed by ambient Earth temperature surfaces. Control of humidity and condensation are important design issues.
PDRC surfaces can be integrated with solar energy plants, referred to as solar energy–radiative cooling (SE–RC), to improve functionality and performance by preventing solar cells from 'overheating' and thus degrading. Since silicon solar cells have a maximum efficiency of 33.7% (with the average commercial panel reaching around 20%), the ...
The refrigerant was developed by the DuPont/Honeywell company and is more expensive per pound than R-134a. R-1234yf can be found in late-model cars and is not cross-compatible with older R-134a or R-12 systems. Of the three refrigerants, R-1234yf is the best for the environment with the lowest global warming potential number which is about a three.
Solar cars have been designed for solar car races and for public use. Solar vehicles must be light and efficient to get the best range from their limited captured power. 1,400 kg (3,000 lb) pound or even 1,000 kg (2,000 lb) vehicles would be less practical because the limited solar power would not take them as far. Most student built solar cars ...
The Quiet Achiever, also known as the Holden Solar Trek, was the world's first practical long-distance solar-powered car powered entirely by photovoltaic solar cells. [ 1 ] The project was promoted by adventurer Hans Tholstrup , with the Australian-made car developed by Larry Perkins and his brother Garry; [ 2 ] and sponsored by BP .
Solar Roof Package: includes Navigation Package equipment as well as power tilt/slide moonroof along with a solar powered ventilation system that uses an electric fan to help keep the vehicle cooler when parked under the sun by venting the interior's heated air with the outdoors.

Forty percent of an IC engine's energy is lost through exhaust gas heat. [7] [8] Implementing ATEGs in diesel engines seems to be more challenging compared to gasoline engines due to lower exhaust temperature and higher mass-flow rates. [9] [10] This is the reason most ATEG development has been focused on gasoline engines.
