Re: Replacing the oil in a oil-filled lopty
Quote:
Hello Guy, I did a meta-analysis of secondary copper (scrap) across the United States and focussed on one particular rogue plant, called Chemetco. During my research, which spanned ten years, I discovered that the USEPA (Federal United States Environmental Protection Agency) were calibrating their emissions estimates for smokestack dioxin and PCB production, based on the figures given to them by this rogue plant. I used to work in copper refining (as an insider, before I became the investigative journalist on this case) and saw exactly what went into the furnace. It was everything from 99.9% purity copper, to bronzes and brasses, residues from brass production, and industrial and domestic waste, such as PVC covered wire. Smelting at 1084 degrees centigrade does not destroy Dioxin. If the residues aren't caught by an effective scrubber system, it does straight up the smokestack. From there, rather than dispersing locally, it can 'grasshopper' its way, rising and falling with the carrying air currents, across a vast distance - thousands and thousands of miles. My research discussed how dioxin from this exact plant, plus others similar, when it was produced in US copper smelters, tended to coalesce in Nunavut, in the Canadian Arctic (Nunavut has now been returned to the first nations). Once it reached there, it was bio-assimilated into lichen, and then from there, into the reindeer eating the lichen, and from there into the human food chain - reindeer meat is a staple food item. For a period, the dioxin was found to be at teratogenic levels in breast milk. The lead scientist on this was Barry Commoner. I researched the Chemetco criminal case and prosecution over many years and have the most detailed study of it made to date. Chemetco can't be defamed now as the company is wound up. But the EPA described them as 'intransigent violators.' They constantly lied and greewashed their way through things. For example, they loaded their furnaces with tons and tons of PVC covered cable, as well as computer and electronics scrap, way above the levels the self-reported to the EPA. Long story short, incineration at 1000 degrees does not destroy dioxin.

Re: Replacing the oil in a oil-filled lopty
I quite agree about the pollution hopping over weather systems.
There is a rubbish fired power station in Newhaven that is relatively new. It only produces visible "smoke" in cold damp weather this being a sign of acid fumes causing condensation in the plume. I have seen this while driving along a near by road while traveling to visit friends. On a couple of occasions the plume has sunk over the channel and rolled back in land along with sea mist causing many complaints in near by Seaford. |

Re: Replacing the oil in a oil-filled lopty
I suppose those syringe and bung kits for refilling inkjet cartridges might work for refilling these LOPT's? I have a Murphy here on the roundtuit pile with a slightly weepy LOPT.
Very brave to drill into the LOPT though, wonder how much clearance you had!

Re: Replacing the oil in a oil-filled lopty
That is exactly what I use Kevin.
Winding some insulation tape around the drill bit allowing just the depth of the can to penetrate. The Murphy types leak at the top through the wire entries and the sealing rivet. Much easier to drill and seal the bottom. John. |
