Connecting To The Grid – Good or Bad for off-the-grid communities?

gravelshoalgroup — Wed, 24 Nov 2010 15:23:36 +0000

No Name Key is a key connected by a small bridge in the Florida Keys. For years the 43 houses that are on the small island have relied on alternative energy, and, of course in Florida, there’s no shortage of sunshine, especially in the keys. Now there are motions being made to connect the small community to the grid, where it will be optional for residents to connect.

Normally, solar panels have associated batteries that the juice is stashed in when there’s an overage. Additionally, the residents of No Name Key are reliant on diesel-fed generators to power their homes. NPR just launched an article on this way of living and how it may be changed forever once the key is hooked up to the grid. Some residents feel that it will compromise the way of living on the island.

The situation on No Name Key seems oddly similar to that of an adjoining island to Nantucket named Tuckernuck. If you’re not familiar with the pristine beauty of Tuckernuck here, it’s no-man’s land. A smattering of houses throughout the 900 square acres, Tuckernuck is not connected to the grid. Gravel Shoal Group has had the pleasure of building or renovating several of the houses on Tuckernuck, and solar is a pretty common occurrence over there, as well as diesel-gobbling generators. There’s no connection to the grid, cable, gas, etc. over there. Residents of the island, however, do just fine. I’m not entirely sure if there are any strictly-Tuckernuck-year-rounders over there (it’s a hop, skip, and a jump in the summer to get over there in the nicer weather, but in the winter you are at the mercy of the weather).

On this comparative note, what are your thoughts on connecting an island that seems to do just fine without grid connection? Do you think No Name Key is at risk for over-development now that grid connection is an option for people who may have otherwise strayed from living there? Do you think the same could happen on Tuckernuck?

Windspire’s silent but awesome power

Check out our video on youtube of what the windspire unit looks like and how quiet it really is.

Of course, we don’t just stop with wind power, but this vertical turbine unit is one of our more recent project. Coming up soon = solar panels!

Magnetic Levitation Wind Turbines. Sweet.

Who would have thought – magnetic levitation wind turbines have been in production since 2006. Jay Leno’s endorsing them, so why not? The average 2.5 KW one is quoted a little over $11k.

This is pretty interesting though, and definitely worth looking into.

Until next time….

Global Baggage

gravelshoalgroup — Fri, 27 Aug 2010 13:50:05 +0000

I found this great post from Discover Magazine yesterday about a kid who found plastic-eating bacteria (yum) and thought it should be shared. Of course, the problem isn’t fully solved but it’s definitely a start. What a great idea, to utilize an existing organism to solve the plastic bag pollution of the world. Ever hear of the Great Pacific Garbage Patch? It’s bigger than the size of Texas. Birds, apparently, are known to feed their young plastic as food and of course, it results in their death. It’s filled with plastic bags, ship generated pollutants, and other fantastic amounts of trash. The plastic is the kicker though….

On Nantucket, the local Stop & Stop (our grocery store here, or one of a few at least) does not supply plastic bags. In fact, I can’t think of anything besides take-out in restaurants that provide plastic bags to clients. Most of the local shops use paper bags as well. Sure, plastic can come in handy when covering your head from the rain, or wrapping up stinky sneakers, or even collecting trash, but overall, the use of plastic on the island is a lot slimmer than I’ve ever seen off island.

Solar Highways? Yes please.

This gives a whole new meaning to the term “paving the way.” What a brilliant idea. Of course, pouring a load of concrete down requires a lot less technical saviness than laying down glass roads that are load bearing, weather resistant, etc. that absorb the sunlight for power.

But how cool? For more info, look at their website for Solar Roadways here.

Re-Cycling

gravelshoalgroup — Tue, 10 Aug 2010 12:19:11 +0000

Recycling and re-using materials is a key element to the environment’s wellfare, and we <3 anything that has to do with keeping things out of a landfill. We’ve all heard the term “reducing the carbon footprint” but this takes it to a whole new level with constructing furniture out of bikes.

We could see this one sitting on one of our beaches:

Especially since some of us here are avid cyclists, we thought everyone would enjoy this one.

Until next time.

Energy Costs

gravelshoalgroup — Wed, 04 Aug 2010 16:08:51 +0000

The past few years has seen a surge in the “green” movement, where people are becoming more and more conscious of the state of our environment and how important it is. What has us all going and motivated in many respects, are the cost saving factors. I found a great article this morning in Real Simple that talks about cutting energy costs by unplugging devices when not in use (which apparently account for a lot more than I realized) updating appliances (even appliances as new as 2000 suck more power than ones made recently)

One thing that I must admit I am not partial to is the disposal of things that suck too much power (like a big fridge, for example). Is it more worth it to keep it out of a landfill where it will take who-knows-how-long to decompose, if ever? Or is it more beneficial to keep it on the grid?

Our licensed home energy rating expert has discussed this at length with clients, what’s more worth it environmentally versus the cost-saving measures, and how that all factors into things. The truth of the matter is that each situation, household, building, etc. is different. But the cost saving ideas are there, and that’s a good thing to keep people motivated.

Until next time.

An Adult Tree House

gravelshoalgroup — Fri, 23 Jul 2010 14:31:19 +0000

Stumbling this morning – found this house in Argentina, where it’s against the law to remove trees when building in a certain town, so the house was built around the trees.

What I like most about this place is that it’s modernized. There was a house we posted a while ago that had been built into the side of a hill and of course, that’s a great design as well. But something about this house just seemed to us that it was really livable (not saying the Shire-looking house was not). There is some real tangible structure here, and I have to agree with the blogger who we borrowed this from:

There’s just something about the combination of wood, concrete and trees that I love.

Until next time.

Not all energy options are created equal

After sifting through a few blogs last week, I came across a blog that recommended a spray foam insulation by Owens Corning. After doing some homework on spray foam insulation, and discussing with our resident expert on eco-friendly and green-building, I was taken aback to find that most spray foams insulation out there contain CFCs (o-zone depleting chemicals). Of course, this does more damage to the environment, so much that, should you spray this particular type of insulation in your home. Our resident expert explains that the damage caused to the environment by o-zone depleting spray-foam insulation takes approximately 30 years to repair the effects of.

So what are the alternatives? One product we found through some of our legitimate networking sources includes this spray-foam insulation from E-Zero, which was used in a Habitat For Humanity home in Connecticut (Habitat has been going green here in Nantucket, too – which we think is AWESOME).

Another accomplished home.

Living in a community full of beautiful trophy homes (some of which are restored from homes that first went up in the 18th century) it’s interesting to find a balance between the lavishly exorbitant and the eco-friendly humble. But luckily, these days, the notion of building “green” is become more and more popular, and the building and design industry has grown by leaps and bounds over the last decade in that respect. I came across a post this morning on a beautiful home built from recycled materials, including broken glass, corks, sticks and stones.

But there was one photo in particular that resounded in my mind as similar to a project we did on Tuckernuck island. The house was an old farmhouse that we restored, but left the walls as much intact as possible. The original builders had wooden walls, and where there were cracks between the wooden boards, they’d put yet another piece of wood to block the wind that would whip through during the treacherous winter months.When it came time to bring this magnificent project up-to-date for the current owner, we left the walls intact, insulated outside of them, and shingled outside of the insulation, leaving an old, barn-like feel to the house’s interior. I saw the photo of the recycled home and thought the walls looked similar to what we would see if there was no insulation or shingling on the outside.

Here’s a photo of the recycled materials house:

And here is our project out on Tuckernuck, we painted the walls inside white:

Until next time.
