Scientists Create Bacteria that Lights Up Around Landmines

TreeHugger - Mon, 11/16/2009 - 16:00
Photo via Reisendame A stunning 87 countries around the world are still littered with undetonated landmines, and their impact is devastating. Tens of thousands of people are killed or injured by mines every year, and they pose a grave threat to ecosystems and wildlife. But an unexpected solution may be on the way--scientists have developed a special kind of bacteria that actually begins to glow in the presence of landmines. Read the full story on TreeHugger

Pumping CO2 Underground to Extract Geothermal Energy

TreeHugger - Mon, 11/16/2009 - 13:47
Photo: Wikipedia, Public domain It Could Work We usually hear about pumping CO2 underground in the context of carbon capture and storage (CCS). But there might be another use for that CO2 in the field of geothermal power. It hasn't been proven to work yet, but some money from the Federal stimulus funds has started to flow to 9 projects that want to test this out. The idea is: "Carbon dioxide that's cycled through hot regions kilometers underground can efficiently bring heat to the surface, where it can be used to generate electricity. The likelihood is that the process would leave lots of ca... Read the full story on TreeHugger

SF Green Festival 09 - Canvas Dreams Offers Honestly Green Web Hosting Services

TreeHugger - Mon, 11/16/2009 - 10:10
There are a lot of options out there for green web hosting. In an effort to green up an energy and resource intensive industry, some use carbon offsets, some sign up for green power plans with power companies. Canvas Dreams, however, is one web hosting company that goes farther than most to be as eco friendly as possible. They shrug off even the thought of carbon offsets and instead go to the root of the problems - green power, a smal... Read the full story on TreeHugger

Ice Could Be Key To Storage of Renewable Energy

TreeHugger - Mon, 11/16/2009 - 09:38
75% of our electricity goes into buildings, and much of that runs air conditioning. The entire system is built to try and cope with the peak loads that come in summer. TreeHugger has covered ice storage systems before; they simply make ice at night, when electricity is cheaper and it is cooler, so it is easier to make, and then run air conditioning during the daytime when it is hot and electricity is in short supply. This can knock the peak off the demand curve and significantly reduce the need for new power plants. But we learned In the Calmac Booth that it can have another significant benefit: It can act as a battery for wind power.... Read the full story on TreeHugger

SF Green Festival 09 - Silo Ink Reduces Printer Waste, Saves 80% on Ink Expenses

TreeHugger - Mon, 11/16/2009 - 08:15
For most people, empty ink cartridges unfortunately head to the trash bin, or if we're lucky, to the reclcying bin or back to the store for recycling. But few people refill cartridges, which is one of the most efficient, green uses. Silo Ink isn't a bottomless ink cartridge, but it's about as close as we can get. The giant cartridges not only reduce waste and are refillable, but will save you 80% on the cost of ink. ... Read the full story on TreeHugger

SF Green Festival 09 - Rentalic Creates Profit Around Community Rental Service

TreeHugger - Mon, 11/16/2009 - 07:25
Community based product service systems are an excellent green product service system allowing a lot of people to use one item when they need it, rather than everyone purchasing the same product only to use it once a year. But what about creating an income based on sharing your stuff? Rentalic is a person-to-person renting service where anyone can hop online and rent their stuff - from parking spaces to holiday decorations - and bring in a little cash, while the renters can get access to things they nee...

SF Green Festival 09 - Flushable, Dissolvable Doggie Doo Bags

TreeHugger - Mon, 11/16/2009 - 06:45
Out on the market for only a few days, Dog Flushies from Absurd Doggie Products made a debut at San Francisco's Green Festival. Plastic bags for picking up puppy poo are a fast selling product, but they aren't usually good for the environment, so the idea of bags that dissolve in water is kinda of appealing. And, the company is putting out a product that is essentially a flushable toilet for outside so you're not traipsing through the house to the bathroom with a bag full of something smelly. Still, we aren't convinced that these are a silver bullet for the problem of "biodegradable" bags. ... Read the full story on TreeHugger

Getting The Awful, Yet Practically Essential Lead Out of Gadgets

TreeHugger - Fri, 11/13/2009 - 12:05
Lead ingots via Wikipedia Lead is unfortunately an important component in electronics, especially when it comes to piezoelectronics. We're mostly familiar with piezoelectricity when it comes to concept devices - things that can generate a charge based on pressure being applied to them. But it is used in a lot of common gadgets, such as phones with touch screens. But the best compounds for piezoelectricity are lead-based, and lead is something we all want to see phased out of electronics... Read the full story on TreeHugger

Greenward Ridge Vent Turns Your Entire Roof Into a Solar Collector

TreeHugger - Fri, 11/13/2009 - 07:21
Sometimes the most impressive products at Greenbuild are the most innocuous and boring looking things; last year I thought the best of show was Agriboard, a SIP made from straw. This year I spent some time trying to figure out this ridge vent for a standard shingled roof with tubes running through it, thinking that there wasn't much surface area on it and it isn't going to do much. Then I realized that all of the heat in an attic runs through the ridge vent and this thing turns your entire roof into a solar collector. ... Read the full story on TreeHugger
