Our planet has been continuously being polluted by the human beings with all the machines that have been invented in the last century. The most used devise that humans use is for sure the car that as we all know emits carbon dioxide thus polluting the environment.
People have become aware of the ongoing pollution and its side effects and because of that they are trying to find some greener ways in order to help the planet. Hence, in the 1980s the idea for fuel cell cars was highly promoted, especially when their system got physically shrunk to fit into a normal car, not the back of a van. In addition to this, they had to be made affordable and the access to fuel everywhere reachable. In time these obstacles have been overcome, but they were still not massively driven by people. The reason for that was that they were not considered very efficient.
Rasa – The New Fuel Cell Car
Rasa made a difference in the use of fuel cell cars as it is more economical and has a more efficient hydrogen distribution system. The company Riversimple, founded by Hugo Spowers, have created the car and its system that made this type of car more reachable to people.
Hugo Spowers is a former motor racer and mechanical engineer of race cars, who 15 years ago got the idea to build a hydrogen-powered vehicle, and thus stopped working with internal combustion engines. He wanted to eliminate the carbon emissions and for that reason he hand-built an aerodynamic car which weighs only 580 kilos, 40 kilos more than the battery of a Tesla Model S car.
The model Rasa is sophisticated vehicle in engineering terms, where the fuel cell supplies the electrical energy that is created when hydrogen is combined with oxygen. The car runs on electrical energy and emits only water. It has the capacity to run for around 300 miles on a tank of just 1.5kg of hydrogen. The hydrogen is compressed to 350bar, not like the conventional industry use of 700bar. This means that it uses less energy, so it saves your pocket and takes care of the environment.
In addition to this, the car has a motor in each of its four wheels thus allowing driving and braking. The recovered energy from braking is being stored in ultra-capacitors. A carbon tub keeps the weight down, while a honed design cuts drag.
What is most important is the fact that the CO2 emissions are significantly lower than any other electric car that is on UK’s mix of electricity generation. Namely, the CO2 emissions (even if the hydrogen is being synthesized from natural gas) are about 40g/km. So, this makes Rasa as green as it can be.
Hugo Spowers focused on saving the planet after he quit being a motor racer and as a result of that founded the company Riversimple. He is well aware that for his plan to work there has to be made a huge change in the traditional system. He reported to Topgear:
“Dinosaurs weren’t replaced by better dinosaurs. Each of the changes demands that other things be changed. The whole system must change, in one leap. “You can’t cross a canyon in two jumps.”
The future would be that the drivers will pay a monthly rental fee to Riversimple that would include depreciation, maintenance and, fuel. In order this plan to be fulfilled the next step is building charging stations for users so that this type of car becomes more attractive to drivers. Hydrogen cars and battery-powered electric vehiclesare our future if we are interested in lowering CO2 emissions in the world.
The Rasa car pollutes less and depletes fewer resources, and that is something that we should consider closely.
