Eco-Artist Creates ‘Puff’ Device to Monitor Car Emissions

Michael Ricciardi — Mon, 23 Nov 2009 19:04:38 +0000

Puff is attached near the exhaust pipe of your vehicle. Its color changes dynamically, visualizing the amount of pollution your car is producing. Green indicates the lowest rate of pollution, red the highest.

Modern artists have often tackled environmental and ecological issues head on, such as through incorporating litter and refuse into sculptures, while other artists (such as photo, video and film artists) have sought to document industrial waste and/or have taken strong oppositional/advocacy stances in their works.

In recent years, many artists have sought to move beyond these “reactive”, commentary, and documentary approaches and create objects and devices that serve practical purposes (if still a bit fanciful in appearance). One such artist/designer is Karolina Sobecka, whose car emissions monitoring device, ‘Puff’ , provides colorful feedback to the car owner on how “cleanly” (or efficiently) he/she is using/burning gasoline.

This author recently contacted Ms. Sobecka and asked her about this device (’Puff’) as well as her other designs, and her artistic/social/environmental goals.

GM Working On Efficient, Shape-Changing, Memory Metal Engine

Christopher DeMorro — Mon, 02 Nov 2009 23:36:13 +0000

Like it or not, at least for the near future most of us are stuck with internal combustion engine powered cars. While a lot of hype is behind future cars and technology, from electric to hydrogen to everything in between, a lot of improvements can yet be made on the ICE engine.

To that end, the Department of Energy has awarded GM with $2.7 million to develop a working prototype of a Shape Memory Alloy engine. In theory, this engine could recycle the waste heat and turn it into electrical energy, perhaps one day even replacing alternators and improving fuel efficiency.

Inflatable Bag Monsters Arise from New York Subways

Rhonda Winter — Mon, 24 Aug 2009 20:07:56 +0000

Innovative artist Joshua Allen Harris has created a menagerie of inflatable monsters that are ephemeral, whimsical and utterly delightful. All of his different creatures are made from old plastic bags, and magically come to life from the air generated by New York city subway vent exhaust.

This post contains additional media. Click here to view the full post.

Steven Psyllos interviewed Harris recently for New York magazine to discuss his inspiration, artistic process, and to unveil a new animated plastic bag beast; the video was shot by Jonah Green.

BMW to Slash Fuel Use With Radioactive Tailpipes

Andrew Williams — Sat, 07 Mar 2009 12:52:53 +0000

German car giant BMW has announced plans to attach radioactive heat-collectors to the tailpipes of future models, in a move predicted to slash fuel use and reduce carbon emissions by around 5 per cent.

The massive fuel saving is bigger than the three per cent achieved by the two current key Efficient Dynamics technologies - stop-start and brake energy regeneration.

The revolutionary technology, originally designed to power space satellites, captures waste heat transferred down the tailpipe and converts it to electricity via a radioactive ‘thermolelectric generator.’

Minneapolis Stops Idling

Philip Proefrock — Thu, 12 Jun 2008 15:46:45 +0000

The city council in Minneapolis MN has adopted an ordinance to prohibit automobiles from idling for more than three minutes. The measure is aimed at reducing atmospheric pollution, but should also be welcomed by anyone who wants to save money, given the currently escalating cost of fuel.

Biodiesel Mythbuster 2.0: Twenty-Two Biodiesel Myths Dispelled

Clayton B. Cornell — Thu, 10 Apr 2008 16:11:27 +0000

Most of us are at least vaguely familiar with biodiesel, but how much do we really know?

While biodiesel is easily the most popular alternative fuel available, it’s commonly misunderstood or misrepresented by inaccurate information. Since the most frequent question I get is, “So what exactly is biodiesel, anyway?“, I decided to write a tome covering all the basics—a one stop shop for all your biodiesel- related questions.

It’s been exactly one year since I published the first Biodiesel Mythbuster on GreenOptions.com, and its popularity made a sequel inevitable. By way of a short introduction, here’s what I wrote last year:

How Diesel Exhaust Affects Your Brain

Clayton B. Cornell — Thu, 27 Mar 2008 19:08:09 +0000

As if it wasn’t bad enough that particulate matter from diesel exhaust causes a range of respiratory problems including 15,000 premature deaths each year, new research shows that even short-term exposure to nanoparticles found in diesel fumes can affect brain function.

Nanoparticles can travel to the brain via the olfactory nerve, where they could cause an oxidative stress response in the region of the brain critical to information processing.

Researchers placed subjects in a room with either clean air or diesel fumes (similar to a busy street), and used a electro- encephalograph (EEG) to measure brain response. Subjects breathing the sooty air showed a stress response in the brain’s cortex within 30 minutes, which continued even after they left the room.
