Biosphere 2 Lung

Biosphere 2 Lung

As Biosphere 2 is a self contained and airtight structure the air inside would expand and contract on warm and cold days which could cause the building to explode or implode!

Two lungs were built to cope with this effect. One of them is pictured above. As the air in the building warmed up the black lung would expand and the roof of this room lowered. When we were there they opened an outside door to ventilate the room and the roof slowly fell. It was quite a sight to see and the draught out the door was enough to make it hard to be heard over the whine.

More on the Biosphere 2 lungs here and here.

Biosphere 2 needed something like a bellows, a lung!
Biosphere 2 would heat up like a greenhouse and cool during the night and during cold, cloudy days. The expansion and contraction would subject the rigid steel and glass structure to enormous pressures as the air inside expanded and contracted. On a hot day, pressure would push out. On a really cold day, Biosphere 2 might implode.

Bill Dempster, Director of Engineering Systems, had an inspired solution, and in time Biosphere 2 got a pair of lungs, or “variable expansion chambers”. The two lungs took the form of graceful hemispheric white domes which protected the liner from wear and tear of the Sun. Both domes, 150 feet away from Biosphere 2 had underground air tunnels connecting them to the main structure. Inside each tank and connected to each tunnel, a gargantuan synthetic rubber membrane with a circular metal top moved freely up and down on a cushion of air.
As air inside Biosphere 2 expanded from the Sun’s heat, it flowed through the tunnels and into the lung, raising its top. As air cooled, the lungs deflated.

Rainbow Umbrella

Rainbow Umbrella

A child opens a rainbow coloured umbrella outside Cork City Library last Saturday. Rain threatened most of the day so it was a good idea to have an umbrella with you, just in case.

Phil is blogging the photos he took, and posted about his trip to Cork too.

High Street, Bantry

High Street, Bantry

High Street in Bantry, Co. Cork is one of the main streets in the town. It was a gorgeous day when I walked around there and shot this high contrast photo on one of it’s corners.

Biosphere 2

Biosphere 2 lies in the dusty hot desert in Arizona. It was originally designed as a self contained “world” where scientists stayed for an extended period of time. After going through the tour, there’s no way I’d volunteer to spend my time inside. It must have been very difficult being cooped up in one building. The Wikipedia page on the project has a lot more detail about what went on there.

Anyway, the building is very striking to look at, especially as the day was fine and interesting clouds added to the scene.

Cock Pit Lane, Cork

Cock Pit Lane, Cork

I wouldn’t be surprised if you didn’t know where Cock Pit Lane was, or if you had never heard of it. It’s a small lane off Cornmarket Street, Cork.

I was fascinated by the slight change in meaning of the English and Irish names. The Irish name, “Lana Troid Coileach” literally means, “Cock Fight Lane”, a much less politically correct interpretation I’m sure you’ll agree. I don’t think the name changed in recent times because the only hit for this lane in Google is a PDF file listing O’Shea family members. Apparently William Shea, a publican, lived on Cock-Pit Lane in 1795. Pity there isn’t any more information.

This wasn’t shot yesterday at the photomeet, but I will be posting more of yesterday’s shots during the week!

A brass band played in front of Cork City Library today and I made this shot while waiting with Phil and his brother Christopher for Damien to appear.

We didn’t make it to Robodock in the end. I was busy and exhausted with a sick baby all morning and I think I’m lucky I managed to get into town at all! Nice to meet up with everyone, including Donal later on in The Newport.

Baby Adam is feeling much better after a lot of care and nursing. Doctor says he’ll be right as rain (and we get enough of that these days!) by Monday. Phew. Poor fella is really suffering.

Electronic waste in the countryside

Electronic waste in the countryside

Last February we spent a weekend in Bantry where I made a couple of very nice shots when I drove into the hills surrounding the town. The area was so nice that I wandered up the road on foot a few yards for a better shot of this lone tree. I was disgusted to see the beige boxes of a PC and monitor lying half hidden in the tall grass of the bog.

Perhaps I should have climbed down and retrieved them but Adam was asleep in the car and we were miles from anywhere. I didn’t want to risk slipping and hurting myself. It’s such a shame those electronics weren’t recycled at the local dump. I wonder what Gardai would find if they looked at the drive in that PC. I wonder if they’d care?

Tomorrow – AJ tried booking Robodock tickets for himself but could only book for the 12 noon show. I thought we could pay at the entrance but obviously it’s popular and booked up. Maybe the bad weather will keep people away but I should be there before 3pm! Keep an eye on my Twitter account for updates!

Must pack WordPress stickers and badges, stickers and badges, stickers and badges…

If you’re wondering, the image above mirrored, otherwise the logo would be backwards!
