I won’t give too much away but I have to give props to former NYC firefighter Kevin Shea for taking an arm-chair idea and running with it. I find it especially funny that his neighbors just don’t get it and actually detest the idea. You can be sure though they would be the first ones knocking on Shea’s looking for refuge or help. Special thanks to the crew at Science Friday for bringing this story to light! Watch the video below and then share your thoughts. Would you live in a geo-dome? Do you have an unconventional home that is easy on the environment and your pocketbook?

The piece of technology Zhang has been toiling away on is called an “anaerobic phased solids digester”.   This type of machine is already in use at wastewater treatment plants and livestock farms around the nation, breaking down the sewage into usable gas.  Zhang has apparently improved the technology to allow the use of more wastes like food scraps, yard clippings and animal manure.  It also apparently cuts the processing time in half and produces hydrogen and methane.  Other systems apparently only produce methane.  That would be a true energy revolution, just like bio-diesel.  Can you imagine the food scraps we don’t eat and animal manure being turned into a fuel for our car?  That would be truly amazing.

UC Davis estimates that about 5 million tons of food scraps go into California landfills every year.  If one ton can produce enough energy for the average day at 10 homes, that year’s worth of food could power 50 million houses for one day or 130,000 houses for the entire year.

If you’d like to read more about Zhang’s system, head over to the website of UC Davis.

I’ve known for a long time that my new mower was not going to be gas powered. I get tired of listening to the almost constant hum of gas powered lawn equipment here in southwestern Indiana. To top that off, the air quality here is already poor since we’re surrounded by several very dirty coal-fired power plants. Just this last week we had two ozone warnings with local officials urging people to avoid fast food drive-thrus and trimming their lawns. The warnings certainly didn’t stop most people around here from doing what they wanted to do and spewing even more pollution into the air.

Originally I thought about just getting a push-reel mower. We have a fairly small front and back yard to begin with so there wouldn’t be a ton of effort required to push-reel mow my grass. Secondly, we live in a small home with a one car garage and don’t really have the room for a big clunky mower to sit around. A push-reel mower could hang up on the wall though and take up no floor space. Then there’s the idea of actually getting some exercise while you’re doing lawn work, something most people seem to try and avoid.

The last couple of weeks though, I changed my mind, thinking I would rather have an electric rechargeable mower. There’s several different versions available right now but T has been questioning just how long the batteries really last and how long it is before they won’t take a charge anymore. The prices aren’t easy on the pocketbook either, ranging from about $250 to $450.

So now I’m back to the beginning again, thinking about getting a push-reel. I’m looking for something that’s going to hold up well over time and has some decent features. The hunt is on! If you have any suggestions or a brand and model you’ve tried out, let me know. I’d like some feedback here!

A new book profiling 10 modern homes and how they're built with alternative energy useage in mind

Lori Ryker, author of Off The Grid: Modern Homes + Alternative Energy, grew up in Texas and has lived several places around the world. She now lives in Livingston, Montana and teaches at Montana State University’s School of Architecture and is a partner of Ryker/Nave Design. I recently had the opportunity to ask Ryker some questions about her new book and her thoughts on the future of sustainable living.

Q: What do you think is the biggest misconception people have about living off the grid?
A: That someone else should take the first step, that alternative energy is something of the future.

Q: You discuss how you think living off the grid brings people closer to where we live, making us more involved in how we live. Why do you think it’s important for more people to be connected to where and how they live?
A: Understanding where we live in the world and the reality of what it takes to live in that place (without the support of mechanical/big energy that creates a pseudo-environment) helps us take responsibility for the place in which we live, and the planet in general. Understanding the conditions of where we live help us make healthier and more responsible choices for environmental conditions such as clean water, air and landscapes; local food sources including plants and animals. Peter Berg coined a phrase in the 1970’s called bioregionalism, which addresses how we live in a place with particular identifiable physical and environmental features that then influence the use and consumption of local foods, materials and native plants, among other things. In the same way, living responsibly with alternative energy requires the knowledge and understanding of regions, bioregions and particular places so that we most efficiently employ the natural resource, such as sun or wind. Such a quality of life also makes us more grounded and invested in ourselves and the world.

Q: Have you found that a lot of people don’t think modern architecture and green features like off the grid living can be combined together?
A: No. I find that most people believe this relationship is normal. However, even three to five years ago this was not the case. There has been a strong and successful popular media push in the past few years to dispel the perception that living off the grid means living in the back-woods somewhere.

Q: You say the book is all about great living in great architecture. These homes certainly aren’t like the earth ships of the 60’s and 70’s are they?
A: No, but every once in a while I drive by an earth ship style place and think to myself, they are still quite sophisticated in their energy use and ability to connect people to the place in which they live, even if they do not appeal to everyone. I would argue that earth ships are also a “style” of architecture. An architect or designer could use the same materials and strategies of an earth ship today and arrive at a vastly different form of expression.

Q: You talk a lot about resource extraction and what you call “dirty energy”. What do you think it will take for people to understand how big of an environmental impact their home has?
A: A completely different way of evaluating home construction and energy use. Such as how bank loans are made, or how homes are taxed, how a builder accounts for the construction of the home and the materials used. In the meantime, we need alternative energy to become more affordable, better methods of measurement of an individual’s energy use and means to control particular components of energy use. Such as being able to separate out use of heating and cooling from media, not simply unplugging. We need more accountability. Simple things such as timers on lights and showers that are already in use in other parts of the world. These strategies remind us that the Earth is not limitless.

Keep checking back for the second half of my Q&A with Lori Ryker coming up later this week.  That’s when I’ll also post the details behind how to enter the contest to win a copy of Lori’s book.  You can get an early entry now by subscribing to my RSS Feed and then posting a comment on this article.

A new book profiling 10 modern homes and how they're built with alternative energy useage in mind

Lori Ryker’s book titled Off The Grid: Modern Homes + Alternative Energy shows that you really can live in a beautifully designed, modern home while reducing your demand for energy. The 160-page glossy, hard-backed book profiles ten homes around the globe and shows how they’ve overcome complete dependence on the grid and leave a smaller footprint on the Earth.

Through example and illustrations, Ryker shows how each technology from geothermal heat pumps, wind turbines and solar arrays, can be integrated into the beauty and design of a modern home. The homes profiled in the book aren’t straw bale homes or Earthships. They range in size from small to large and sparse to intricately decorated. If you’re embarking on a journey to build a new modern house and have considered making it more green, Ryker’s book might be just the ticket to turning your visions into reality.

Stop by later in the week for a Q&A chat with Ryker and I’ll also tell you how you can have a shot at winning a copy of her new book.

They’re goal is also set on continuing to provide safe, abundant and affordable feed, fiber and food.  The group’s new blog, just rolled out last week during their 5th National 25x’25 Renewable Energy Summit, contains a host of information about the progress toward that goal and what each state is doing to get there.  The blog also offers RSS feeds for those of you on the blogging go.

The packages would give homeowners tax credits for investing in alternative energy sources like wind or solar and for making their homes more energy efficient.  Alternative energy companies can also carry their current tax credits for an additional five years.

I think this is fantastic and a good way to encourage people to start making the move to alternative energy and maximum efficiency.  Unfortunately I feel like unless these packages were to be extended for several years, it’s not going to do much right now.  The economy is in such poor shape that who, aside from the wealthy (once again), have the money to invest in solar panels and wind turbines right now?

I don’t think the answer will reveal very many people willing to make the investment in these rocky times even with as much as it will pay off in the long run.  I hope our government realizes that this is a vital move to keep alive for several years and not just one tax season.  Do green tax breaks like this one do enough to encourage you to make the move to alternative energy sources?  Share your thoughts and opinions by posting a comment below!
