Why does a boiler need such a complex fan? Once water is boiling sending steam up the stack will cause a draw. However the problem with advancing technology is working out is it safe, if you fit anti-stall technology to an aeroplane and a fault can cause the plane to dive into the ground it is clearly not safe.
So with power steering how do you insure in 20 years time it is still safe? The only way is some self diagnostic software which alerts driver, as with the ABS warning light, you would need a power steering warning light. Unless with a failure you can still steer the vehicle.
English is one of the problems, my son has bought a new boiler for his central heating, if it was to do as the name suggests he would say it was faulty. There is a tendency to call new items after the item they replaced, some times with an extra word, like electronic transformer, or electronic ballast but neither are anything like what we know as a transformer or ballast.
Keeping up is hard, but also knowing about old technology, teacher asked class "there are two types of transistor anyone know what they are?" son answered "field effect and bipolar sir." told wrong it is NPN and PNP, to which son bust out laughing, maybe not best response.
When I saw teacher son had already told me, and teacher had still not realised his error, when enlightened he said that must be some thing new, but actually the field effect was invented before bipolar but bipolar was perfected before field effect.
So was not even a case of keeping up. However I had not heard of a FET until 1981 so reasonable excuse.
