High on Aquidneck


Abbey Wind Turbine in Narragansett Bay

Some times things fall into place quickly. We'd like to think that that means they were supposed to happen or that some heavenly force is at work directing our steps. I don't know about that but it is nice to think so and sometimes things do fall into place with a rapidity that makes them seem heaven sent. They certainly did for us recently in our quest for great images in the Narragansett Bay area.

We passed the large wind turbine that has recently been erected by the town of Portsmouth on Aquidneck Island. It occurred to us that a shot from the top would help us live up to the aerial part of our name and that it would very likely be quite spectacular. I poked around the website for the town of Portsmouth and eventually found the email and name of a man who I could contact about the possibility of getting up to the top. He responded in short order and with some enthusiasm for our work and for the idea of taking a panorama from the top. He didn't hold out much hope about getting to the top however as the company that erected it still controls access and they haven't been very cooperative of late. Our idea of taking a photo from the top of a turbine was quickly tied up in a combination of governmental red tape and corporate ill will. It turns out that they're being sued by every contractor who worked on the job but more on that later.

It took a few days to dawn on me that the Portsmouth turbine is not the only turbine on Aquidneck Island. The first turbine was erected at the Abbey School, also in Portsmouth. An email to someone in the administration earned me a response from Brother Joseph. Brother Joseph teaches at the school and has been an integral part of the turbine's existence since it appeared above his head like a light bulb signaling a good idea years ago. He interviewed all of the neighbors. He asked for and evaluated bids. He "did the math" and found the funding. He watched it go up and start turning and he's been speaking about it ever since on behalf of the school.

There's a lot of good things to say. It's only been in operation in light winds for about 3 years and yet it has nearly paid back the initial investment on the part of the school. That includes some substantial grant money but no tax breaks since the school is a non profit. Without the grant the payback period would have been extended a couple of years. With a payback period of 3-5 years and an expected life of 25 years and the current value of the electricity generated at something like $200k per anum ... the book keepers are happy.

Drawbacks? Are there scads of people in the area coming down with the mysterious "turbine syndrome?" No. Noise? A pleasant swish swish. Sub Aural Noise? No one can hear it. That's what sub aural means. If a herd of elephants were passing through the area there might be a problem with sub aural noise but none have appeared of late. Are their dozens of students running around the base of the turbine with crazed looks in their eyes saying "the blades! ... please stop the blades!!" No. None of that. Drawbacks seem to amount to the fact that there are a few houses and a few buildings on campus that in the right wind and atmospheric conditions get the shadows of the blades passing their windows ... that's annoying but only for short periods of time. Don't forget: the shadow is moving. It doesn't show up on cloudy days. It disappears when the turbine turns sideways to the sun. I don't know if the whole neighborhood turns to the turbine each morning and sends a silent blessing to Br. Joseph and what he's done for green energy in Rhode Island but on the whole it seems to be thought of as a good thing.

Brother Joseph liked the idea of a high definition panorama taken from the top of his turbine. He often has to climb it but can't share the magnificent view with too many people because of safety concerns. Now with the panorama he can. We had to wait for over a week for the weather to clear in the aftermath of Hurricane Bill. The week of August 24th began with some clear air but a lot of wind. Finally, on Thursday, the wind died and the sun came out and sky turned blue from horizon to horizon. We had our window of opportunity! Three of us strapped on our safety harnesses and made the 170' climb to the nacelle of the turbine. Brother Joseph assured us that we'd just joined a select group of people that had been allowed to make the climb. We certainly felt lucky to be that high in sky.

When our pulses had returned to normal Chris took the equipment from the bag that had been hoisted to the top from the rear of the nacelle. He had it all functioning in fairly short order and Brother Joseph and I climbed out onto the roof to place the camera and its robotic mount on top. The wind was so light that we didn't even anchor it down. Chris hit the trigger. The mount spun. The camera clicked and we had our panorama. Our hope is that it'll find it's way into one of Br. Joseph's powerpoint presentations and will be projected onto the wall in front of a series of enthusiastic audiences that are interested in sharing this part of Brother Joseph's journey. What very few of them can do in reality, they can all do virtually from the safety of their chair while they learn about the ins and outs of erecting wind turbines.

Fair Journey,

Brian Shriver

Little Planet Views



The Krpano viewer provides a rich interactive viewing experience. In addition to panning and zooming with your mouse if you right click in the panorama you get options for other projections. My favorite is the "little planet view". The normal view allows you to pan thru all that is visible from a point but the "little planet view" gives you all that is visible from a point all at once. To my mind these polar panoramas are like belly buttons. You have your innies and you have your outies. By dragging your mouse in the vertical direction while in the little planet view you are able to morph between these two projections.

In the near future we plan to convert a series of the panoramas you see on Vr Journey into versions for print to be available for online purchase. Below are the different projections we plan to offer. If you don't want to wait till then or have seen one that you think is begging to be printed email us and we will convert it to the projection you desire and get it printed for you. The images below are low resolution but the printable versions are about 100 megapixels and can be printed quite large.


This is the spherical projection. It is the same image that the web page viewer uses to allow you to pan 360 and zoom. It has distortion at the top and bottom similar to the flat map of the world unwrapped from the globe.

This is that same projection but cropped.


This is the "little planet view" in outie mode.

And this is the "little planet view" in the innie mode.

Enjoy playing with the various projections and if would like it printed email us the name of the panorama and let us know which of the four options above you would like.

Fair Winds,

Chris Blake

The Fastest Indian

He was the world's fastest Indian .... or he rode the world's fastest Indian. Both phrases are correct because man and machine were one when the speedometer climbed towards 200 mph. The bare facts of Burt Munro's story strain the credulity of anyone who's ever ridden a motorcycle or participated in the development of any sort of machine technology. When the truth of the story is know, hands covered in machine oil from around the globe come up into a silent salute. The man was truly incredible and an incredible inspiration to tinkerers and backyard mechanics tweaking their machinery everywhere.

So what did he do? What are these bare facts. Burt Munro was born in New Zealand in 1899. He came back from service in WWI and bought his Indian motorcycle in 1920. It was the 627th of a series that had only been in production a few years in Springfield, Massachusetts. It had a top speed of only 54 mph off the production line. Burt began to modify his Indian to gain speed in 1926. By 1967, after 40 years of tinkering Burt traveled to his personal mecca at the Bonneville Salt Flasts in Utah and set land speed records, some of which have yet to be broken.

Here's the thing. He did it almost single handedly. He had no team of engineers and mechanics and financiers behind him. He was it .... engineer, mechanic and driver on the budget of a handyman and retired motorcycle salesman. He cast his own pistons, rods and cylinders. He designed his own aero dynamic fairing. He jiggered with fuel mixtures and carburetor settings. He modified and tuned his suspension. Then he tucked his wool pants into his socks, squeezed himself into his machine and traveled like a bat out of hell at speeds that have yet to be equaled by motorcycles that displace less than 1000ccs. It boggles the mind.

Relatively unknown outside motorcycle racing and speed record circles in his own day, Burt has achieved some fame after his death with the help of the movie industry. The movie "The Fastest Indian" starred Anthony Hopkins in the role of Burt Munro. Burt left behind a legend of skill, perseverance, and courage which typifies the ingenuity and resilience of the New Zealand spirit. But you don't have to be a New Zealander to appreciate him. Anyone who's ever stood with a wrench in his or her hand and explored their own limits and "thirst for invention" find inspiration in the story of Burt Munro and his beloved Indian motorcycle.

Fair Journey,
