The components we are installing have chips in them, but we don’t worry about what chip because the manufacturer of the product keeps it working the same way. The modicon quantum Plc uses the pentium 166 chip and was released in 1994 and I can still buy it today from Schneider although they encourage new installations to use a newer product. I am sure I will still be encountering old quantum Plc in the field when I retire, the platform will have a 50 year lifespan.
Even when a line of controllers is end of life the manufacturers provide an upgrade path to their newer product line.
You have drawings that show how it works and a supply of spare parts. When it stops working people can figure out why using the drawings and then fix or replace the broken or worn out components.
25k seems excessive, but 10% of a years anticipated revenue might be appropriate.
It is not unusual to have to but up a bond in order to bid on a contract.
the building was saved and moved instead of being torn down in order to preserve architectural heritage. From the outside the building doesn't look special.
Giving a grant to an existing company with a long history of technical excellence and delivering products to build a new product and a factory for it means jobs that don’t go away. A power plant built creates jobs to run it for as long as it exists.
On the other hand All construction jobs are not permanent - they finish building the project and have to move on to the next one, if it is the factory for the power plants, the power plant itself, the next power plant, or something else.
18 million pounds is a lot of money, but it’s a pittance compared to what tech companies are raising from VCs. In relation to the size of tech companies and the size of investments in them, 6000 jobs and the kick start to an industry for 18 million pounds seems like a bargain to me.
It’s 6000 jobs, generating electricity without producing carbon, sustaining an industry and construction and manufacturing know how, and creation of a product for export. These seem like worthwhile pursuits to me and a good use of public funds.
The cost of the property reflects the value of the rents, the cost of financing, property taxes and maintenance. Rents are probably not that out of wack with the landlords costs. If the landlords revenue does exceed costs you could see it as either money the landlord needs to save for future major repairs like new roof, new appliances, payment for their labour, return on the down payment invested, etc. if you can’t beat them join them and if you can’t join them then maybe it isn’t quite so easy and cut and dry.
There are little air strips all over the place you could land at and then instead of having to figure out a ride to your destination which can be difficult in rural areas you can drive.
A Canadian study linked the illness symptoms of Canadian and American diplomats in Havana to heavy use of the pesticide used against mosquitoes for Zika virus.
It sounds like they changed the settings on the protection relays synch check function to allow it to close the generator breaker with the generator out of sync. Or maybe they added a phase shift correction factor to the voltage transformer inputs so the relay thought the generator was in sync when it wasn’t. Either way changing some settings that allow a machine to be destroyed is ... not an achievement. Engineers all over the world put great care in to calculating and identifying the relay settings that will protect the machine instead of allowing it to be damaged. Uploading incorrect settings is like intentionally missing a basket in basket ball, it’s not very impressive.
I am sure generators have been connected to the grid out of phase and had their shafts broken before. I have seen a colleague accidentally jumper out the entire sync check circuit and we would have closed the generator breaker had the breaker’s close coil not been burnt out (the reason for the errant troubleshooting).
It is concerning that destroying this diesel generator was even necessary. Maybe they needed some good video to get some funding.
Now on the other hand if they somehow hacked the relay then that’s a problem. Older relays just had serial ports but new ones have Ethernet and you can send settings by ftp, and things I remember from bbs days like Kermit
Or zmodem or something. Not ssh yet anyway.
So yeah it is easy to do damage, you can shoot insulators or transformers with a gun or you could release a thousand squirrels or snakes and that would cause outages too.
One power plant was great it just never seemed to have any electrical problems. Someone went to update the relay settings after it has been operating for years and found out no settings had ever been uploaded to the relay!
I would be interested in reading one of the studies in which the default was set to an inferior product and people stayed with the default despite there being a superior competitor and nearly zero effort required to switch.
i'm not arguing that it's bad to pay to be the default. If the default service is worse than another people will switch to the other service. People install all kinds of apps on their phones, they can switch the default search engine too.
are your advantages that prevent industrials from installing their own cogen know-how and economies of scale in project management, procurement, frabrication, installation and commissioning? I wouldn't have thought a company like fortis would ignore 7MW for 30 million * however many compressor stations they have that are near the distribution lines.
I got a Synology 218. It does checksumming like zfs to guard against bit rot. and I didn’t have to spend any time wading through how to’s and blog posts to make it work, “just works” out of the box
