The merits of beer have been heralded from the plays of Shakespeare to the roofs of frat houses. Almost all of us have sipped a cold one at least once (or several thousand) times in our lives. Have you ever given a thought, however, to that bottle in your hands? In a time when we're becoming more clever in creating dual-purpose functions from the most obscure of items, the beer bottle has found a new afterlife: assisting in the creation of hot water.

Sure, this probably isn't very new. With the right materials to capture heat, almost anyone can create their own hot water. This is the first time, however, that I've seen a beer bottle solar collector used so effectively. If necessity in the mother of invention, then Ma Yanjun from China's Shaanxi province is proof that a little motherly love can push you in the right direction. Yanjun came up with the idea of stringing together a collection of green beer bottles to heat water after his Mother became less than comfortable with their previous setup. From the article,

A couple of events happening this weekend came across our radar over the last few days, and we thought you might be interested

Tonight in San Diego, the newly-formed Eco-Investment Club will hold a "Greenmeet" at the Hotel Solamar (downtown). International real estate investment strategist Gary H. London, of the London Group, will be speaking about his recently-published article “Green Economics as Applied to Development." Gary will be joined by Kyle Cross and Ruben Robles of Destino Real Estate; they will speak on "Wholesaling Green Propeties."

Tickets for the event are $25 for the general public, and $10 for club members — details and ticketing information are available at the Club's website. We're especially pleased to announce this event, as Eco-Investment Club founder Yeves Perez will soon be joining the Green Options writing team!

On the other coast, in New York City, Tomorrow Unlimited will present Jennifer Leonard, a designer and writer who co-authored Massive Change, and Sarah Rich, a solutions-based journalist who co-authored Worldchanging: A Users Guide to the 21st Century in a discussion entitled "Sustaining Change." Jennifer and Sarah will explore ideas about making the ideas of sustainability sustainable themselves for the long haul. They’ll also discuss ways their own thinking on sustainability has changed since completing their respective projects. In doing so, they’ll ask questions about the role of innovative design and technology in our global future, confront the trendiness of contemporary environmental thinking, and consider the importance of change itself for the long-term viability of the sustainable movement.

Our guest blogger, Sheryl Canter, is an Online Writer and Editorial Manager at Environmental Defense.

If you have a garden, you know the climate is warming. In temperate zones, the last frost in spring comes earlier, and the first frost in fall comes later. The longer growing season may allow you to grow vegetables you never could grow before. But you also may have noticed your weeds are more aggressive, insect pests are more of a problem, and pollen plagues you all summer long. You're not imagining things!

For over 40 years, gardeners have relied on the USDA Plant Hardiness Zone Map as a guide to what they can grow in their area. But the USDA zone map hasn't been updated since 1990, and gardeners have seen detectable shifts since that time.

In 2003, the American Horticultural Society (AHS) updated the zone map with a grant from the USDA, and published a draft of the new map [PDF] in The American Gardener. Based on temperature information from July 1986 to March 2002, the map showed widespread warming, with zones edging northward.

The USDA rejected the new map without explaining why, and said they would update it themselves. Four years have passed and still they have not released a new map. But the National Arbor Day Foundation has just released one, current for 2006. Like the 1990 and 2003 maps, the Arbor Day map is based on 15 years of data. The changes between 1990 and 2006 are dramatic; the U.S. is clearly getting warmer.

Editor's note: This week, Ecotality blogger Steve Caratzas takes a look at a recent New York Times article that outlines Thomas Edison's green thinking. This post was originallly published on June 3, 2007.

The New York Times has a terrific article about Thomas Edison, and his unparalleled impact on our daily lives, as well as our current (you should pardon the pun) environmental situation.

No individual deserves more credit, or blame, for America’s voracious electricity consumption than Edison, who conceived not only that generating station but also the notoriously inefficient incandescent bulb and a slew of volt-thirsty devices.

However, Edison was also a green visionary of sorts, whose ideas about sustainable energy encompassed windmills and an energy-self-sufficient home.

Want to improve the indoor air quality in your home or office? Get a houseplant.

Plants can absorb air pollutants and can alleviate some "sick building syndrome" symptoms such as headaches and eye, nose or throat irritation which may be caused by inadequate ventilation, chemical contaminants (ie. VOCs, carbon monoxide) or biological contaminants (ie. mold, pollen).

You don't have to overdo it. One plant for every 10 sq yards of floor space should be plenty.

The aviation industry may one day be powered by algae. Manufacturing giant Boeing says that a biodiesel alternative made from algae could be the aircraft biofuel of the future.

Last month, in an 8-page document plainly titled "Alternative Fuels for Commercial Aircraft", Boeing presented their estimation of the alternative fuel sources that could 'relieve worldwide pressure on crude-oil derived fuels' and drive air travel to carbon neutrality.

The biofuel debate has largely glossed over the 'friendly skies' while high fuel prices continue to take their toll on the industry. No biofuel we have yet can step up to the plate. Ethanol collects water and corrodes the engine and lines while biodiesel freezes up in cold weather (ie: cruising altitude). Don't forget pilots' general resistance to change and a life and death dependency on reliable fuel, and aviation biofuels don't have a leg to stand on.

Editor's note: Please welcome Green Options' newest writer, Elizabeth Redmond. Elizabeth is a sustainable designer working in Ann Arbor, Michigan. Her past experiences include working with her sister Sara Snow on a Discovery Health TV series called Get Fresh with Sara Snow, where she researched sustainability and built environment content.

I asked Elizabeth to give me an "elevator pitch" of her focus here at Green Options. Her response:

Today's green products and services seem to be an eclectic collection of "lighter tread". I propose that we begin to design and interact with products and systems that encourage heavy treading, where a heavy active footprint is one step in the right direction without a half step in the other. My objective is to tell you how things work, and enable you with the information to make responsible, and conscious decisions about society, lifestyle, health, and sustainability.

More than tornadoes, hurricanes, snow, or cold weather itself, heat is the number one weather related cause of death in the United States. So urban dwellers (that means half of us in this world) beware! Much of our urban heat is due to a phenomena called the Urban Heat Island effect. An Urban Heat Island is a metropolitan zone that is warmer than the surrounding, less developed area. The EPA reports that "On hot summer days, urban air can be 2-10°F [2-6°C] hotter than the surrounding countryside”. What does this mean? It’s going to be a hot summer, but luckily we can do a couple of things to help cool your stroll down the sidewalk.

First, how does this phenomena work? It is all about the energy transfer of solar radiation to our built environment. Lets go back to high school physics and review. All you need to know is that heat from the sun (radiation) gets stored in our constructed impervious and dark surfaces such as concrete and pavement (insulators). During the day these surfaces of high heat capacity collectively act as a massive heat energy reservoir. (I.e.: concrete can retain nearly 2000 times the heat as an equivalent volume of air). Next, the heat on the surface of these materials mixes with the already hot air and you experience a hot gust that feels dense enough to chew on (convection).

I’ve recently been introduced to two artists who use large-scale installations to provoke awareness and shift public perspective on current social and environmental crises. They hit a point of synergy in two works that both feature shelters destroyed by water — one directly related to New Orleans and Katrina, and the other sparking the same associations through the archetype of Atlantis. Both artists strive to incite action towards sustainability and social justice with a visual jolt to the system. Takashi Horisaki: A Latex Replica of a NOLA Shotgun House, Post-Katrina When artist Takashi Horisaki left his native Japan, he moved to New Orleans to spend his first three years in America earning an BFA at Loyola University. He left before Katrina ravaged the area, and returned in 2006 to discover “how seriously those of us living outside of the victimized area fail to grasp the reality of the tragedy suffered by New Orleans and the lethargic pace of recovery.” So he decided to help outsiders get a better perspective by creating a sculptural replica of a condemned house in the Lower 9th Ward. This is a continuation of a series Horisaki calls Social Dress (this one being called Social… (more)
