Comment What exactly? (Score 4, Insightful) 379

"It's not Amateur Night on Planet Earth anymore, things have gotten terribly, horribly real,"

Poor people are living longer, earning more, eating more, all over the world. There are fewer large wars.Sure there's a few existential problems around, but you are living in a very successful century so far as homo sapiens is concerned.

" Our current best estimate is that 100% of global warming is caused by human activity. [realclimate.org]"

Gosh, that is quite hilarious. Presumably you have heard of Ice Ages large and small and the Holocene optimum. Why has natural variation in temperatures ceased just because we are on the scene?

I'll assume you are going to claim fossil fuel burning is a large part of changes since 1880 (I would), but if you look at HADCET you'll see that recent (since 1880) spikes in temperature change are not unusual in rapidity or amplitude over the few hundred years of that data. Now I realise I am using HADCET as a proxy for global temperatures, but its a damn sight better than a few trees.

100% wow. 100% he he hee. Thanks, you've cheered me up no end, the chicken littles really are just plain silly

Comment Funny numbers from a mechanical engineer (Score 2, Informative) 805

Last year my taxable income was $190000. You can buy shares in my employer. I wouldn't.

So, 16 years ago I paid a year's pay at the time (85k) in cash for a solid, but unattractive, house in a working class, decent suburb.

Three years ago, after I got a lot of pay rises, because good real engineers are well paid, I paid 300k cash to have it knocked down and a new one built. That is now worth 600k.

So which of you dummies in the IT game can't figure out how to do that?

Meanwhile, I bought a weekender. For cash. But that was mainly to annoy you lot.

That's quite a can of worms you've ripped the lid off. Superficially, yes, you are right.

But the reality is that ~half of electric power is generated from coal, not hydrocarbons. (as an aside In my opinion burning hydrocarbons in powerstations is dopey, oil and natural gas should be reserved for uses where their extraordinary energy density is most useful, basically aeroplanes and the like,)

The consequence of burning coal is that for many many many regions worldwide, an EV actually produces more CO2 than a similar sized diesel or petrol car.

Sorry about that.

Your description of the mechanical path is correct, but most manufacturers who care still allow the driver to sense some of the torque being applied to the steering axis of the tire. That is to say, if I plot unassisted SW (steering wheel) torque vs latacc, compared with assisted torque vs latacc, the EPAS removes a large, but not all, the torque, even when parking which is where the most assistance is used.

Various companies do intentionally or unintentionally get rid of all the Mz (torque on the tire about the vertical axis) feedback to the driver.

Of the other forces/torques on the tire it is reasonable to say that most manufacturers tend to try and eliminate steering wheel torque as a response. For instance, torque steer, single wheel bumps, braking on unequal mu surfaces, should all ideally be isolated from the SW, although I must admit in the latter case I don't mind a bit of feedback via the SW.

Comment Re:Define "Fully" automated (Score 1) 278

Can I perhaps guess you haven't worked on a real farm for a full week? Every single manual task is designed to be the limit for a healthy person, for example grain is hefted in 50 kg (112 lb) sacks. How many 50 kg sacks can you shift in a day? great cos that is your job. Those neat little straw bales are about 15 kg (33lb), you need to stack 40 of those so the hydraulic clamp can pick them up. Now there are some reasonably cruisy bits, sitting in a tractor listening to the radio while ploughing or whatever. That is of course the easiest job to automate.
