While our students here in Nigeria are busy dancing shaku shaku, following up BBNaija and so many unfruitful ventures, their counterparts around the world are making a great impact to make the world a better to live.
Emerging from the prototype vehicles lab (otherwise known as PROVE Lab) at California Polytechnic state university, a group of students has created the first vehicle designed only to break the solar-powered land speed record. the solar car is named ‘dawn’ and is designed to reach 65mph without any battery.
The vehicle, which is the result of two and half years of work, was designed using hundreds of hours of simulation, with some wind tunnel testing for the aerodynamics. The entire vehicle produces only a few kg of aerodynamic drag and is powered entirely by a 2kW solar array, which means there are no batteries used in the car unlike other solar cars designed for races across America or Australia.
The vehicle has no steering wheel, and getting in and out of the car involves the top half pitching up and forward, like the hatch to a science-fiction creation. The team chose 605 individual SunPower solar cells to create their array – The same that were used to fly the solar impulse II aircraft around the world. these are similar to the kind that is often seen on rooftops around the world and are fairly inexpensive technology in 2018.
Every part of the car was designed and built by students including the software. Most of the car’s construction is aerospace-grade carbon fiber, meaning that even with a driver the vehicle weighs less than 200kg in total, allowing it to rest on high-performance bicycle wheels rather than conventional vehicle tires which would produce more resistance. a special flap on the upper surface (hidden by solar cells) will deploy if a sensor detects the car is starting to take off the ground at speed and will kill the lift to keep the car on the ground and the driver safe.
