Advancing Technology From water-cooling to the self-driving car by Roger Moroney O nce upon a time the only way to cool an engine was by using the air. And of course designing fins around the barrels to spread the heat and drag cooler air closer to the cylinders within. And basically it worked except in extreme climate cases (like crossing Death Valley in mid- summer) I am sure there would have been, shall we say, issues. But air cooling was the way it was until the arrival of basic radiators and liquid-cooling systems aboard machines like the early Scotts. Yep, fins were effectively the way to go, and even the GP outfits chose to use Mother Nature’s wind despite some building machines with a line of six cylinders across the frame. I can remember some of the early two-strokes when they adopted radiators, and the niggles they had. All part of the growing process I guess. And I also remember the sensation on the streets called the Suzuki GT750 — a three-cylinder giant of a thing which had a radiator up front which appeared the be the size of a small garage door. For the very early 70s, the GT750 was a real eye-opener... the first Japanese motorcycle to hit the shelves with a liquid-cooled powerplant, and it accordingly drew taglines like the “waterbus” and (rather unkindly but given the size of it) the “Water Buffalo”. It was a breakthrough in cooling and year-by-year, factory-by-factory, the radiators took centre stage on the cooling landscape. Today, they are simply accepted... and when I see a finely restored old air-cooled unit parked up I usually stop and take a look. All part of the thing they call evolution and advancing technology. A thing I suspect, and fear, is getting just a little out of hand in the world of four wheels. It costs a lot of money to pursue technology and develop new systems and test them and refine them, so manufacturers 88KIWI RIDER have to make cost cuts somewhere to allow them to do that. So something has to go (apart from another 30 jobs as another robot is bolted to the floor). And it appears that something is a steering wheel. For cars that do not require a driver do not need steering wheels...although maybe they’ve bolted one in the boot beside the spare tyre just in case there is a solar flare or a global hacking strike with ‘Made in North Korea’ written all over it. Now I realise I am labelling myself as a bit of a Luddite here... one of those people who does not embrace rapid advancements of technology and job-swallowing automatons, but I am not only suspicious of self-drive cars but I am afraid of them. We who spent all our riding lives up at the front end all know what it’s like to ride pillion. I was a dreadful pillion passenger. I wanted the control grips thankyou very much. A bit the same in a car. I was not designed to be a passenger. Only aboard a bus or an aircraft or a boat am I comfortable with the notion of having someone else do the thinking, equating and driving. The big players in the automotive world are at it though and several are now involving time frames in their development and those times are not far away. However, I was delighted to read recently how a kangaroo threw a huge spanner into the development process, because it seems the sensors on the test self-drive car, which was being run through its paces in the otherwise isolated outback of Australia could not determine how far away this potential barrier was...b ecause it keep hopping on and off the ground and it therefore could not get a fix. Marsupial 1, Automotive Technology nil. This is where motorcycles win because you can’t have a self-drive one... you just can’t. They need a pilot, therefore they will become the saviour of the human race. I can see the scene from 2031 now... A silly looking car with three bored and grim-faced people strapped inside it... all on iPads, or whatever, and all being taken to their destination by a robotic system which has caused the extinction of the driving licence. But the riders going by on their motorcycles will have cheerful faces. Because they can stop when they want to and they can actually beep the horn when they want to. And blip the throttle (just a little) at the Stop sign. Motorcycles 1, Automobiles nil.
