A team of researchers from the University of California, Los Angeles (UCLA), has developed a solar-powered electric vehicle (EV) that can travel 64 kilometers (40 miles) purely on solar energy, without the need for charging. This innovative vehicle, called the SPARK, uses a Photovoltaic-Thermal (PVT) system to convert sunlight into electricity and heat, which powers the vehicle’s electric motor.
The SPARK’s PVT system is designed to optimize energy conversion, with photovoltaic cells generating electricity and a thermal absorption system harnessing heat. The vehicle’s solar panel covering is made of a flexible, lightweight material that can be adjusted to optimize energy absorption.
The researchers tested the SPARK on a 64-kilometer course in Los Angeles, with the vehicle starting from a fully charged battery. The vehicle’s solar panels generated an average of 1.4 kW of power, which powered the electric motor to propel the vehicle at speeds of up to 50 km/h (31 mph).
The experiment demonstrated that the SPARK can travel a significant distance purely on solar energy, eliminating the need for charging. This has significant implications for the development of sustainable transportation, as it reduces dependence on fossil fuels and eliminates emissions.
The SPARK’s design also has potential applications beyond transportation, including powering outdoor equipment, such as camping gear or smartphones, in areas where electricity is scarce.
The researchers are continuing to improve the SPARK’s design and performance, with plans to test the vehicle in various environments and climates. They are also exploring the potential for integrating the PVT system into existing vehicles, allowing them to travel longer distances on solar power.
The implications of this technology are far-reaching, with the potential to transform the way we travel and use energy. As the world transitions to a more sustainable and renewable energy-based future, the SPARK and similar innovative technologies are expected to play a critical role in reducing our reliance on fossil fuels and mitigating climate change.
