The Laxey substation of the Manx Electric Railway is one of the last mercury arc rectifier installations in the UK to have been doing its original job on its original site. There are very few left at all, let alone a complete working station. Now decommissioned, its survival is in the balance and we need support for this great old piece of British engineering before the powers that be decide to scrap it, as has been threatened. Engineers and non-technical people alike have been fascinated by the mercury arc for nearly a century - please sign the petition before next week's meeting to help ensure that such a great example is saved for future generations to learn from and admire:

If you're interested in the technicalities of mercury arcs, there's a page about one of mine here:

Excellent - keep it going while you can! Alas none of the recs under my wing are original installs, they are ones I've pulled out and saved, I would love to look after one still doing real work.
 
It's owned and operated by one of our clients, I will be there in September and can get you a couple of photos if you like. There's a possibility unfortunately that it maybe nearing the end of its working life, as next year there is talk of an upgrade of the DC power system of the particular installation but I will keep in touch and let you know.
 
You and Tony could maybe fire it up, I'd love to see one working! :)
Every day is a mercury arc day here! I have one rigged up most of the time, not always the same one. When we get the museum going we will have half a dozen - the biggest is 1400A output at 250V DC. We won't be running that at full power while I'm paying the bills though. There's a few places you can see them working, e.g. Internal Fire Museum and Laxey... Oh cr*p, you can't see one working there any more.
Get signing...
 
Would you like me to ask our client what their plans are with the unit if its decommissioned? Would you be interested in it at your museum? I can't quite remember what output it was but I'm pretty sure its a couple of hundred amps.
 
A few pics - that would be me with the ECC. Used to power a 30t gantry crane amongst other things. The little Nevelin is part of a fully regulated battery charger for a 240V lead-acid secondary lighting battery that was in a large London building. I've had this one powering all sorts of things!

A perfect marriage - mercury arc and fairground ride.The bulb could be displayed in the ride centre so the riders can see it light up as the ride pulls away. Actually, don't give me ideas, I've enough to do as it is.

Archy it is getting on slowly, there's a balance to strike between working to raise funds and sorting all the stuff out and shunting it into place. Had hoped to hold our first open day this year but time is slipping and I have too much work on. Had some fantastic donations recently and it's been as much as we can do to pick them up and put them in the stores ready. Next year, for certain, and rest assured there will be mercury arcs ablaze when we open.
