Greener Gadgets Conference: Design Competition

One of the highlights of the Greener Gadgets Conference was, of course, the design competition. Last week I gave descriptions of a few of the online favorites, but last Friday, a winner was chosen.

Four designs were selected to battle it out through audience applause: The Power Hog, Tweet-a-Watt, Laundry Pod and viagra from india Indoor Drying Rack (as would be expected at this conference, the decibels were measured with an iPhone application). The Tweet-a-Watt designers walked away with first place and $3,000; Power Hog came in second and the designers received $2,000 and finally, Indoor Drying Rack came in third and the designer received $1,000. The Laundry Pod designers received a gift from one of the conference's sponsors, but didn't officially place.

So what's the Tweet-a-Watt? What does it do? It is actually a rigged Kill-a-Watt electricity meter that plugs into any outlet and publishes daily updates on buy cialis no prescription your power use to best prices on viagra Twitter. The judges and audience agreed that knowing your friends were watching your energy consumption was a great motivator to conserve. The major detail that set this device apart is it's great! cialis testimonial the fact that it is already a working, Twittering gadget, publishing the buy cialis us design team's electricity use as you read this. The team also made it an open-source project so anyone who wants to start Twittering their kWh, can do so. You can see the Tweet-a-Watt after the jump.


Clock On Bottom, Garden On Top

The Timeless Garden by Francesco Castiglione and Tommaso Ceschi is a clock that runs on mud. To be precise, compounds in the mud react electrochemically with metal terminals in a recycled plastic container used to house the mud and grow small plants such as herbs and grass. The Timeless Garden therefore eliminates the need for a wall plug or batteries.

Frankly it seems like a lot of work in order to get an eco-friendly clock even if the indoor plant produces oxygen and absorbs CO2. But at the very least, you'll know when it's time to water your plant.

Capturing the Power of Whirlpools

An Austrian engineer, Franz Zotlöterer, has developed a new method for small scale hydropower by creating a whirlpool that avoids many of the problems typically associated with hydroelectric generation.

In terms of levitra 100 green power generation, solar and wind get much of the attention. Hydropower is as green as wind and solar in terms of limiting emissions, but some of the ecosystem disruption associated with large-scale hydro have taken it off the table as a choice for good green power. However, smaller scale hydropower options can provide electrical power and provide additional benefits to the waterway.

The original idea behind the vortex was, in fact, not power generation, but water purification. A vortex in the water serves to natural cialis efficiently aerate the water and to aid in more rapid breakdown of contaminants.

The idea to use a continuous, strong vortex flow actually occurred to Franz Zotlöterer while trying to solve the inherent problems with water quality of the natural swimming pond he had set up in his own garden. He finally decided to build a small rotation basin to aerate the water – and it worked. He then began to viagra next day think about other potential fields of application for his aeration concept: drinking water supply, wastewater treatment, electricity generation. - Aquamedia

Instead of channeling the we use it order viagra pill water directly through a turbine, vortex hydropower creates a spinning vortex, and draws energy from the swirling water. This approach makes it possible to generate energy without completely blocking the waterway and buy low price viagra eliminates the need for much screening or filtration. Small debris is not a problem for vortex generation as it would be for a conventional turbine. Furthermore, fish are able to pass by the vortex chamber without harm. The vortex operates at slower speeds, and the large open chamber makes it possible for fish to pass even going upstream. The vortex also reduces the temperature change of viagra buy the water, and can more readily be integrated into the natural river environment.

The pilot plant only needs a fall of 1.3 meters (4.25 feet) and, with a flow rate of 1 cubic meter per second (about 265 gallons per second), produces 8 kW of electricity, enough for about 14 average European homes. A head of as little as 0.7 meters (2.25 feet) is possible for a vortex generator. The much lower rise makes it easier to locate a vortex generator on a smaller waterway, without the need for high dams and other interventions typically associated with hydropower.

The vortex system is about 80% efficient, comparable to a standard turbine. However, the vortex cannot scale as large as a turbine power plant. A vortex has a range of performance up to about 150 kW, while a traditional turbine can reach up to 100 MW.

A system that both generates electricity and helps to clean and purify the discount generic viagra online water is a great technology of the kind we like to see.

Nip, Tuck… and Fill Up?

I've heard of people going to extremes to make biodiesel, but this story has to be the strangest thing I’ve heard in a while. A Beverly Hills doctor is cialis fast delivery currently under investigation because the fat he removed from his patients was allegedly used to fuel his Ford Explorer and his girlfriend's Lincoln Navigator.

You can't make this stuff up.

Craig Alan Bittner, who has since shut down his practice and moved to South America, said his patients wanted him to use their fat for fuel. “Not only do they get to we recommend generic viagra from canada lose their love handles or chubby belly,” wrote Dr. Bittner on the website (which has since been taken down), “but they also get to take part in saving the Earth.”

Most biofuel in the U.S. currently has beef tallow or pig lard mixed in with soybeans because the animal products are cheaper to add in than pricey soybeans. Animal (and, presumably, human) fat gets drivers the same amount of best online viagra mileage as regular diesel, but it needs to be processed more than vegetable-based biofuel.

Besides the visit web site canadian healthcare fact that using human fat for this purpose is a crime (under laws that probably few of us knew existed, using human medical waste to fuel cars is illegal in California), experiments such as these don’t exactly help the reputation of biofuels. And even if the thought of running your car on human flesh doesn’t creep/gross you out, I would venture to guess that it would have that effect on most people. Sorry, Tyler Durden. Back to the drawing board.

Meanwhile, it’s unclear what is going to happen to Dr. Bittner. He is currently volunteering at a clininc in South America, and he maintains that all of his liposuction procedures were performed without a “single serious complication or infection”. Some question whether he could have even done what he claimed to just try! mexico cialis no prescription have done in the first place, since Lincoln Navigators don’t run on diesel…



PV Shades Give New Meaning To Word “Sunglasses”

Thanks to thin films and - in this case - dye-sensitized cells, designers can put solar panels pretty much anywhere. The fact that Hyun-Joong Kim and buy levitra uk Kwang-Seok Jeong, the two designers created the SIG (self-energy converting sunglasses) probably has less to do with the inherent brilliance of this creation, and more to do with the fact that they were looking at a pair of sunglasses one day and said “Hey! What if we put SOLAR CELLS in these?”

Still, at least they actually did it... although it would take a lot of guts to actually wear them in public, even if the things do power your iPod. They aren’t exactly Ray Bans. Also, last time I checked solar cells worked best when positioned to face the sunlight. But people don’t like to look into the sunlight, even when wearing sunglasses. Seems like a waste to make solar cells that will end up capturing so much less energy than they could in another application.
