An electric tea kettle that boils exactly as much water as you need — not two or three times as much.
It would be nice if more manufacturers paid attention to the details like this — it takes a lot of energy to boil water.
This is how it works: The internal reservoir holds a full capacity of water ready for use, while the measuring button allows any quantity – from a single cupful to full capacity – to be released into the separate chamber for boiling.
The result? Exactly the right amount of water every time you boil –and no more waste.
If you avoid boiling 6 cups of water a day, this adds up to 1.2 KWH per day, or 430 KWH per year and 900 lbs of CO2 if your electricity comes from a coal powered plant.

Biogas- and water treatment plants are now able to produce electric power from biogas and deliver it directly to consumers over the grid. A revolutionizing micro power plant, the XRGI, has been developed and approved to produce electricity from biogas, and this gives new opportunities for the biogas- and water treatment plants.
With a guarantee for effect and low service expenses Biogas- and water treatment plants now can produce power to cover the plants own consumption and supply the grid with 100 pct. CO2-neutral power.
“The technology is now so mature that power production from Biogas- and water treatment plants is very interesting – both economically and from an environmental point of view. XRGI has been designed to run at least 30.000 hours without any repairs, and service is only to be done every 4.000 hours. This gives extremely low operating costs. ,” says Bjarne Bogner, CEO of EC Power, the company that developed the technology behind the XRGI-systems.

New biofuels technology developed by North Carolina State University engineers has the potential to turn virtually any fat source – vegetable oils, oils from animal fat and even oils from algae (possible also human left-over fat) – into fuel to power jet airplanes.The technology – called Centia™, which is derived from “crudus potentia,” or “green power” in Latin – is “100 percent green,” as no petroleum-derived products are added to the process. Centia™ can also be used to make additives for cold-weather biodiesel fuels and holds the potential to fuel automobiles that currently run on gasoline.
NC State received provisional patents to use the process to convert fats into jet fuel or additives for cold-weather biodiesel fuels. The technology has been licensed by Diversified Energy Corp., a privately held Arizona company specializing in the development of advanced alternative and renewable energy technologies and projects.
