RIVERSIMPLE RASA IS UNVEILED

We are team Riversimple. This February we are proud to present the first production prototype of a revolutionary hydrogen fuel cell car from Wales – Riversimple Rasa.

Not so long ago, Rasa looked like this.

LCVPrep1

This is the ground breaking powertrain, built in Wales.

The new car reflects a simple idea that was first mooted in the 4th century BC by the great philosopher and scientist, Aristotle. It is the idea that something new begins, not with predetermined structure and characteristics, but with a blank slate – tabula rasa – moment of potential.

We set out with a blank slate, to design a car for the world in which we now live, shaped by the best technology available to us and answerable to our most pressing concerns. We set out to build a local car that will take people on their local journeys, in the way that they wish to travel, at a cost that is affordable – and without leaving a heavy footprint of air pollution and environmental degradation. To do this we selected a still evolving, but incredibly promising and safe technology. This is hydrogen fuel cell technology.

We are a small, multi-talented, hard-working team of engineers and designers. Riversimple is headed up by company architect Hugo Spowers and supported by some big thinking business experts, without whom we would not be in this position today. As independents, we can tell you it has been no mean feat.

Riversimple Rasa is a wonder … Great to drive, safe to drive, fun to drive, light in every respect of the word, quick to refuel, and with a super strong framework of carbon fibre.

On the day that a lively crew arrived to film Rasa in action on the roads for the first time, the sun came out across the Welsh mountains – creating the perfect backdrop. At no extra cost.

Now that you have seen the car, we hope that you will join the Riversimple movement

FROM COMPLEX TO RIVERSIMPLE

Behind the excitement surrounding the forthcoming launch of the Riversimple Fuel Cell Car, are a specialised team of engineers, designers and business professionals. We are real people, working through a pivotal time for Riversimple, each with different skills and experience to bring to the table.

At the moment, everything is focused upon bringing new (disruptive) fuel cell technology to market, but the Riversimple Mk2 is part of a bigger picture – the changing requirements of day to day transport and the nature of the business model that underpins it. Riversimple’s purpose is “to pursue, systematically, the elimination of the environmental impact of personal transport”. Everything we do – the design of the car, the structure of the business, the people we work with – is in pursuit of this goal.

We have attracted some top talent

HAPPY NEW YEAR FROM RIVERSIMPLE

2016 is a significant year for Riversimple. Back in October we ran our first test of the Mk2 at the Royal Welsh showground in Builth Wells.

LIGHTER ELECTRIC CARS

When you stop to think about the wide range of cars on the market today, from gas-guzzlers to electric cars, it’s clear that design choice can have an enormous effect on how much fuel the car consumes, how this will affect performance, and what impact it will have upon the environment.

We have designed the Riversimple Mk2 to be extremely fuel efficient with ultra low emissions but at the same time fun to drive and with a great range.

Fundamental to the great spec of our new car is lightness. Continue Reading..

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..
