What's The Greenest Insulation? It's Getting Harder To Decide Every Day Screen shot from Youtube video What's wrong with this picture? It is in a video promoting Ultra-touch denim insulation, showing an installer pushing a full-size batt into an irregular cavity. Either the insulation isn't going to work because it is compressed or it is going to pop the drywall right off the wall. The installer also isn't wearing a mask, even though the company's material safety data sheet recommends an OSHA approved air mask. Even though I got seriously schooled by an Ultratouch distributor at a home show last year, I still have problems with batt insulation; it is rarely properly installed around electric wires and other irregularities and does not seal as well as sprays. Post consumer recycled jeans are not good for the chemically sensitive, for whom this is a prime product. More on Denim Insulation:What's The Greenest Insulation?

The first use of wood gasification dates back to 1870s, when it was used as a forerunner of natural gas for street lighting and cooking. In the 1920s, German engineer Georges Imbert developed a wood gas generator for mobile use. Second World War The technology became commonplace in many European countries during the Second World War, as a consequence of the rationing of fossil fuels. A network of some 3,000 "petrol stations" was set up, where drivers could stock up on firewood. In 1942 (when the technology had not yet reached the height of its popularity), there were about 73,000 producer gas vehicles in Sweden, 65,000 in France, 10,000 in Denmark, 9,000 in both Austria and Norway, and almost 8,000 in Switzerland.

Using suphp To Secure A Shared Server The challenge with securing a shared hosting server is how to secure the website from attack both from the outside and from the inside. PHP has built-in features to help, but ultimately it s the wrong place to address the problem. Apache has built-in features too, but the performance cost of these features is prohibitive. This has created a gap that a number of third-party solutions have attempted to fill. One of the oldest of these is suphp, created by Sebastian Marsching. suphp: Running PHP As A Specified UserInstalling suphpConfiguring ApacheSome BenchmarksOther ConsiderationsConclusions suphp: Running PHP As A Specified User Like Apache’s own suexec, suphp is a solution that allows PHP to run as the user and group that owns any particular website on a shared hosting server. suphp consists of two components: mod_suphp, an Apache module that replaces mod_phpsuphp, a setuid binary that replaces Apache’s suexec It relies on PHP/CGI having been installed onto the server first.

Tour of the First PassivHaus in UK Photo: B. Alter This lovely looking Victorian house in west London seems deceptively straightforward except for a tiny plaque on the front door. It notes that this is the second house in the UK to reach PassivHaus standards. And that is no mean feat. Last year Lloyd outlined the challenges of bringing high environmental standards such as PassivHaus to this heritage house. Photo: B. Tom Pakenham, creator and owner of Green Tomato Cars ( a green mini-cab firm) has renovated this house to PassivHaus standards. The year long conversion is finished now, and as can be seen, it is a beautiful, light and airy house and a showcase for people and architects wanting to have a green home. The essence of PassivHaus-ing is insulation. Edward Borgstein, an engineer at Green Tomato led a group of architects (and one non-technological person--this TreeHugger) around the house and outlined the steps of the renovation in great detail. And what a job. Photo: B.Alter: Heat Extractor Photo: B. Photo: B.

Vortex Filters Organic Fertilizer Dispensers | The Urban Farming Guys transcription of “Vortex Filter DIY — Organic Fertilizer on Demand” video..by The Urban Farming Guys.. These guys right here are our vortex filters. Retail, they’d be about $4,000 apiece…DIY version, about $100..You might be able to do it for cheaper. We’ve got a 55-gallon drum, with a cone built into it, down into a shower drain. Out here, you can pull off your fertilizer every day for your garden. I’ll show you about that. We’re pulling off a pretty incredible fertilizer. Stage One, you wanna settle out as much of the solids as you can before you send it to your mechanical filter so you don’t have to change your filter pads all the time. Stage Two, whatever solids sneak by get caught in four filter pads so that the only thing left to filter now is the ammonia. Stage Three, is the biological filter. Stage Four, the plants use the nitrates & send it back clean. & you can do this on a much simpler level. Alright, we make our vortex filters out of 55-gallon drums.
