DESIGNING THE LOCAL CAR

There is a story about the original design brief for the 2 CV.  It was written in the 1930s when much of France was still rural farmland and in the brief it was stipulated that
2CV “it should be a car that you can drive across a ploughed field while it’s loaded up with trays of eggs, without breaking the eggs”.  This idea touches upon something important to us all. It’s about having a car that becomes part of the way we live.  At Riversimple we have been busy designing that car.  We think of it as a local car.Continue Reading..

What’s special about a Hydrogen Fuel Cell?

At Riversimple we think of hydrogen as an energy carrier not a fuel.

Petrol and diesel are primary fuels – you can dig them out of the ground – but if you think of hydrogen as a fuel you can make the wrong choices. In the past, some car companies invested a lot of time and money designing cars that burned hydrogen. Due to the quantity of gas required, the engineers also experimented with super-cooled liquid hydrogen, but there were numerous problems and the designs were dropped at a fairly early stage, mostly without reaching the market.

Riversimple at the National Exhibition Centre

At the beginning of November, Team Riversimple were to be found at the National Exhibition Centre in Birmingham.

The annual Advanced Engineering Show has acquired an international reputation, attracting and demonstrating the latest developments in engineering. We had Riversimple’s Alpha Mk2 rolling chassis (the entire Hydrogen car minus external body shell) on show and it certainly attracted plenty of interest.

 

 

At present the design of the body shell is being kept under wraps, but from the point of view of the engineer it is the nuts and bolts of the interior that really fascinate.car-2

This is the culmination of fifteen years development at Riversimple. Designing around hydrogen fuel cell technology has allowed us to re-invent the car for the modern world. We have four electric motors, one in each wheel and these motors are also the brakes – recovering over 50% of kinetic energy when braking. There are super-capacitors to store this energy and the recovered energy is fed back into the system to provide 80% of the power for acceleration. The primary power source is a relatively low powered hydrogen fuel cell ( 8.5 kW) housed in a beautifully constructed framework of lightweight composites.

Our overall design gives us a groundbreaking efficiency and range, many times better than inserting fuel cells into conventional, heavy, vehicles. This also means it will be agile and fun to drive, and with a massive feel good factor, as we strive towards zero cost for the environment.

THIS IS WHAT IS POSSIBLE – Mobility as a service

New technology tends to come on to the market at a high price. Over time, and as production becomes established, the price falls. But with giant corporations turning out 300,000 cars per year per automobile plant to cover capital production costs, what hope is there for a radically different car in today’s global market?

Re-inventing the car

The petrol car was shaped by and to a certain extent contributed to the shape of the 20th Century. This was a time of rapid and sustained change. Pioneers of the first combustion engine, the first Bentley, the first Mini and the first Ferrari were working against a back drop of horse-power, steam power, the discovery of oil, the industrial revolutionContinue Reading..
