of downstate Illinois is actually Red. Cook county from which "Hot" Rod Blago is a Democratic Machine product, does not represent in any meaningful way, the rest of the state. Yes, there are some isolated "Blue" areas around the University towns and the St. Louis Metro East, but look at the map below. See this article in the Chicago Sun Times. See also the 3-D map.
Blagojevich's main interest here appears be to position himself for national office. He ran on a platform of "It won't be business as usual." He was right. It's worse! Downstate state workers are being laid off while others are being hired in Chicago. Family and friends make up a large proportion of the higher paying jobs and appointments being handed out. It's a blatant power grab by the "Chicago Democratic Machine". The mayor's office in the capital, Springfield, was won by a Democrat with a large war chest provided by Chicago interests. And so it goes.

I've got two of them. One is a Swiss Army Quartz which steps one sweep hand movement per second. The other I've had since 1969. It's a self-winding Rolex Explorer that still looks great and keeps good time. Of course it's entirely mechanical. Its sweep hand makes several small steps per second. I paid $157 for that Rolex back then at at duty-free shop in Gibraltar. I saw one that sold for $4000 on Ebay a few days ago. My eyesight isn't all that good anymore and I like the high-contrast black face and silver/green hands on both of them.
At one time I worked for Texas Instruments and still have one of their LED completely digital watches. They were a total pain, IMO.

Over in the Tampa / St. Pete area and have done both kinds of drives. We put in a couple of very nice German-made AC drives at one of the big hotels in St. Pete Beach, but renovated the service elevator and kept the existing DC motor, replacing the MG set with our own SCR drive. I did renovation DC drives at the VA hospital there, too. We're out of that market now, though.
I agree that the major elevator companies (Kone, Schindler, Otis and ThyssenKrupp) are doing a lot more AC drives now on new construction and on jobs where the whole installation is replaced. The smaller regional company that I work for does a LOT of renovations where the existing DC motors and machines are perfectly useable with a new controller and SCR drive.
Regarding the shunting of excess energy, we put in an AC vector drive last week on an old freight elevator in a department store building. The previous setup was using the two-speed, 8-pole, high-slip, AC motor and gave a pretty rough stop since it was levelling at 50 Feet per minute whild full speed was 100 FPM. With the vector drive on the high speed windings of the old motor it's as smooth as a baby's bottom, BUT when going down with a full load, there are dynamic braking resistors that are dissipating about 1KW and thus making a lot of heat. It's actually less efficient than if it was a full regenerative DC drive with a DC motor where almost all the excess energy is returned to the power line. At least that's how the DC drive that we manufacture from the ground up works.
Give my regards to your dad. In our company his job is called an adjuster and the guys who do that are the top mechanics. Everyone of them I've worked with are very sharp and a pleasure to be associated with.

If you are talking about brand new elevator installations, it may be true that VVVF is in the majority, I don't have actual data for that, but if one looks at the whole current installed base, DC still rules for traction. The lifetime of an elevator motor and machine combination is extremely long, especially if it gets even basic routine maintenance on the bearings and brushes. I have installed modern regenerative solid-state DC drives on elevator motor/machine setups that were originally installed before the great depression of 1929. Within the past 5 years I have seen elevators that were installed before 1900 that are still being used in their original configuration with the original motors and controls. No, they don't meet current safety code and are not allowed for passsenger use, just moving materials.
While powering a DC motor from a motor-generator set seems archaic, there are still lots and lots of them in use. I know about this as the company that I work for is in the elevator business and maintains a great many such elevators here in the MidWest.
Back to the subject of regeneration -
The power company doesn't get pissed since the regenerated energy is returned in phase, both through the motor-generator sets and the solid state drives. We certainly don't want to have large resistor banks to dissipate excess energy and it's definitely more energy/cost efficient to do regeneration. Those elevator machine rooms are hot enough in the Summer without having an electric heater in them.
"Do the Right Thing. It will gratify some people and astound the rest." - Mark Twain
I wasn't referring to AC motors in my original post, but rather DC motors. I apologize for not making that clear.
The use of AC motors in elevator applications is increasing with the advent of cost-effective AC vector drives, but the majority of presently installed traction (cable driven) elevators use large DC motors (up to as much as 150 H.P.) which definitely function as generators virtually as well as they function as motors. At least that's what I was taught when I took my motors course in Electrical Engineering school back in the 60's.
In our shop we have a test setup for our solid state DC motor drives that has two 40 H.P. DC motors connected back to back with one of them being a generator with its armature connected to a resistor bank serving as a load for the motor being driven. We adjust the mechanical load by selecting different configurations of the load resistor.
BTW, I'm an Engineer with an elevator manufacturer.
"Do the Right Thing. It will gratify some people and astound the rest." - Mark Twain
has nothing to do with the mechanical brakes other than that it takes some of the load off them.
Remember that any DC motor can work equally well as a generator. In regenerative braking, the motor becomes a generator providing mechanical resistance to slow the vehicle and the energy produced is fed to the energy storage device, either batteries or super capacitor where it can later be recovered and used over.
Actually this is fairly common practice in certain types of traction (cabled) elevators where the motion of the elevator car, say, up in the case of an empty cab with counter-weights heavier than the cab, actually pushes power back into the 3 phase power lines. There are no big resistors needed to consume the energy produced when the drive motor becomes a generator. This is efficient in terms of energy consumption.
Mechanical brakes on elevators are normally set only after the cab is electrically stopped and held at floor level.

As I've said so many times before, when are the media companies going to realize that the shift has happened. I'm sure the buggy whip manufacturera bemoaned the advent of the high-tech automobile and might have even wanted to outlaw them or require that all automobiles, by law, have to sport a fully functional buggy whip, but it didn't happen that way.
Big media, instead of plugging the dike with thumb-like legal shenannigans, should be expending their efforts in finding a new business model that will actually work instead of pissing off their paying customers. The march of technology is relentless and people are resourceful. It's nothing but a losing game for RIAA and MPAA to try and stop it. Wake up, folks.
