I dont think toyota is going to release 3d models of components and assemblies of their cars from the 80s/90s
I would REALLY like them to.. its a nice thought, but its not going to happen.
unless someone gets a car, takes it apart, turn all components into 3d models and assemblies, and sends those CAD files away to be made by a CNC company.
send CAD file to CNC company instead of 3d printer $$$$$ for 4 cylinder engine block
profit?
people hail these 3D printers as something new. CNC lathes and milling machines have been doing this for decades. its just the materal is diffrent. you DO know you can send a cad/3d model to a company and they will make parts for you out of plastic/stainless/titanium, without inventing the words "3d printer"
I think the only problem we have is with petrol prices being too high due to supply reducing as time goes on.
if a replacement fuel is avaliable, with near infinate supply, then thats great!
I, personaly dont care about "global warming/climate change and the topic of greenhouse gases". if England gets as warm as the south of France, and the 10mm "rising sea levels" are offset by using seawater as a fuel, then I call that a 100% success.
well what do you expect? these devices use microcontrollers and are limited by size of memory in the chips. its not allways possible to secure to the Nth degree, so one must analyse the risk of the hardware provided. dont connect them to a public network. at most. connect the ethernet to a windows PC that can recive emails, but is not connected to the company LAN.
PLC hardware must remain hardware modules from 20 years ago, so its no good putting in the latest and gratest microcontroller in every year, if it breaks compatabilty for that RS232 card the company made 20 years ago.
in other news, dont send unterminated strings over TCP ethernet, i.e. without carriage return, to a toshiba robot. It will crash the controller in the robot and stop the process.
in further news, dont fill up your gas tank with water, dont hit your spouse and dont drive on your sidewalk.
I agree, thats not how you do it,
But wasnt stuxnet expoliting the functionality of a windows PC talking to a CPU? a la prodave.
AB PLCs come to mind, there was a website going round that explained if you password protect the PLC and then tried to unlock it later, the password would be send back to compare against in the programming software. They probably fixed that, but next time im on a PN-DP site, im going to try to find the easter egg HTTP site on the PN CPU!
its entirely possible to run an entire nuclear power plant from the control rod insertion to button that opens the front gate off a single Siemens PLC, e.g. their S7-400 with a big CPU. off the CPU comes Profibus which can go directly to input sensors, pnumatic valves, HMIs. The profibus is quite a safe thing, becasue it is just RS485 underneath. The new thing that siemens is touting is profiNET, which as the name implies is just the profibus protocol over ethernet.
with control systems running off ethernet is fine, but siemens also do DIN mount 100mb/s ethernet switches where anyone can plug a laptop in and stop/start/upload more code to the entire network with their prodave application.
As an actual control systems engineer who uses the Siemens Simatic range of PLC/HMI/Servo drives, it doesnt take a two year old who knows how torrents works to download the WinCC flex HMI programming software, throw together a few screens with some built in clipart of pumps and generators and claim he has hacked a city's water supply... or uranium plant, or Area 51 air con system..

I think another fundamenal problem is why does one need the entire western world need such large ammounts of processing power on the move?
Do the goverment know of an upcomming energy crysis?

get CAD file.

V8, not G8.
as soon as possible, hopefully.
so thats the fuel problem solved then
they are also known to weigh nothing.

I think he means 60+ years to build another 10,000 nuclear plants
