Solar power is versatile and readily available almost anywhere. The explosion of solar panel technology has not only made it possible to power homes and enterprises with abundant, clean power, it has opened new horizons for smaller scale applications such as gadgets and consumer goods. Integrating innovative design, utility, and often extreme portability, these are some of the incredible solar-powered products that have sprung from the solar revolution and challenged the boundaries of invention.
The world’s first solar-powered sports car
The Immortus by Australian start-up EVX Ventures is said to be the world’s very first solar-powered sports car. The car is covered in a shell of solar panels measuring eight square metres and powered by a lithium battery. The car features special ‘solar racer’ tyres that minimise rolling resistance, and the car can clock speeds of up to 160 kilometres per hour with battery power. With just solar power, the car still manages to reach an impressive speed of 80 kilometres per hour.
The Immortus weighs just 500 kilograms, less than half the weight of a standard sedan. The low mass-to-power of the car and its aerodynamic design has its manufacturer describing it as ‘a car of practically infinite endurance’ that has no fixed range that theoretically can be driven forever.
Solar-powered beach mats
University student Antoine Sayah invented the Beachill for a class project when asked to invent something useful and environmentally friendly. The result is a lightweight mat with a five-watt solar panel and in-built fridge that keeps your drinks cold. You can also charge your phone while you relax on the padded mat, which comes in a variety of colours. Shortly after posting his idea on his Instagram account, Sayah attracted attention from buyers all over the world and sold dozens of prototypes for $150 each.
MIT researcher Daniel Nocera has invented a potentially revolutionary storage technique powered by water and sunlight. Inspired by the photosynthesis process of plants, the Artificial Leaf uses solar power to create hydrogen and oxygen from water. The resulting gases – chemical fuels – are then stored in a fuel cell for later usage. The ‘leaf’ is actually a solar cell made from silicon, and it does not need any external parts to work. It starts generating power when placed in a container of water and exposed to sunlight. Nocera expects commercial applications within a few years.
Although still in the testing phase, SolarWindow is a new and promising product that could allow glass-based structures such as office towers to capture solar power from windows. These solar windows are coated with a transparent film lined with tiny solar cells capable of generating solar energy. Made from polymers, the film can be applied at room temperature.
Wireless solar keyboard
If you like to be mobile while you work, Logitech’s wireless solar keyboard can free your from both wires and batteries. The thin (1/3 of an inch thick) keyboard features 2.4GHz wireless and gets power from both outdoor and indoor light, so you can choose to work inside or in the great outdoors.
