  • BP Oil Disaster Rant (Baz Studios) 2010 These are my thoughts on the current BP Offshore oil disaster. If you agree, leave a comment. With enough comments, we can force them to act. The Alberta Tarsands look very good compared to this crisis! Lets all work together to stop offshore oil drilling once and for all. Stopping all offshore oil is the only solution. Lets make a difference together. Lets save the planet together. You can make a difference. We can all make a difference together. How many Offshore oil wells need to be shut down? All of them! It's never a good day to die! We must Plug these offshore wells and permit life to servive! Here's a way to plug the wells: To prepare a wellbore to be shut in and permanently isolated. There are typically regulatory requirements associated with the P&A process to ensure that strata, particularly freshwater aquifers, are adequately isolated. In most cases, a series of cement plugs is set in the wellbore, with an inflow or integrity test made at each stage to confirm hydraulic isolation. Bleedoff Line: A section of manifold containing the valves and piping necessary to bleed off pressure from a vessel or system. Bleedoff lines may be exposed to widely fluctuating pressures. They must be adequately secured, and consideration must be given to safe handling or disposal of the resulting fluids.

  • Rice Hull Ash Today we're experimenting with rice hull ash and road base. We're using a small measuring device so we can get about 10% rice hull ash. This is what rice hull ash looks like. It's hulls from rice that's been burned. It looks like ash from a forest fire. It's a natural pozzolan which can make the soil harder. We're going to start off with about 10%. I'm adding it in thin layers and tamping it. This will simulate an earthbag. Okay, it's pretty solid, just like you would tamp an earthbag. The idea is to use rice hull ash in replacement of cement. That big bag over there was only $3.60 and, of course, cement is much more expensive. Now we're making a second test block with no burned rice hulls, no ash, just the road base so we can compare the two blocks. We're just adding a little earth at a time, the same consistency, the same amount of moisture we put in earthbags. Just spread it out in thin layers. You notice the plastic on the tamper so it doesn't stick. So here's our finished rammed earth block with no ash. We'll see how they compare after they dry. This one had a little more moisture and seems like it's stronger, but then again this one has ash, which should add some strength, so we'll see. I noticed this was crumbly when I took it out of the form, which means it probably had a lack of moisture. Some people may think this is just earth, it can't be strong. But this is rammed earth, which can last thousands of years. You can learn more on our earthbag website. But just ...

  • Hempire Materials: Application of Hemp and Lime Plaster Ireland: Brendan Kelly is the plasterer in this video. Brendan Kelly's lime plastering has previously been featured on the RTE program, "About the House" (www.rte.ie This is Brendan's description of the work: I did a small job for a couple near Kinvara, Co. Galway, Ireland. They had blocked up a door in their house. While this is a very small job, the video demonstrates very well how easy the application of the Hempire plaster is. The door was blocked up using Heraklyte shredded wood boards. Because these boards need to breath, a lime render was necessary. Hempire lime/hemp ecoplaster was used for several reasons: a) as can be seen from the video, it is relatively simple to apply by "spraying" using an air compressor, and a high quality finish can be obtained relatively easily b) it has improved water-proofing properties (over sand/cement renders) c) it has a high thermal insulative properties (I have worked on several houses where they used this product solely for it's insulative properties) "Hempire Building Plaster is a unique ready mixed plaster made from the chopped stem of the industrial hemp plant and reacted with lime and pozzolan in a novel process" "Hempire Skim Plaster is a unique ready to use plaster made from finely classified stem of the hemp plant and reacted with lime and pozzolan in a novel process.It has been specifically designed to float over Hempire Building Plaster to give a perfectly smooth finish.

The Romans used natural pozzolans to build structures that are still standing today. The Colosseum , The Water Aqueducts and others. If the Romans had used a lime based concrete instead of a Pozzolan based concrete, you would not be seeing those structures today.
