Save the Bay's Vegetative Roof


Save The Bay Roof in Narragansett Bay

We took this photo in mid August near the end of the day. It's not a bunker dug into a grassy hill overlooking Narragansett Bay. It's actually a high tech and beautifully designed building which houses a world class champion of green causes, namely Save the Bay. It only looks like a bunker from this angle. It's north wall is set into a grass covered berm about 10 feet high. The roof extends upwards from there and is covered with vegetation.

It's an old idea made new. I remember a childrens' story about an old woman who had a cow on her roof. I believe it really happened! Save the Bay probably couldn't graze a cow on their roof. They might manage to nest a few birds however. Vegetative roofs have made a comeback among the green crowd and Save the Bay is certainly that. They're quite energy efficient in the summer among other things. I can't expound further without doing research so I'll have to leave it at that. If you want the full story about vegetative roofs and why Save the Bay wanted one on their new building then you'll have to visit their website and find out more.

To take this photo we set up our 40' tripod in the building's main entrance on the north side near the end of the day. Our camera was high enough to see over the top of the roof to the beautiful view looking south over Narragansett Bay. The north side has the main entrance but it's not considered the front of the building. The front faces south and looks out upon that fabulous view. How clever of that architect eh?

We intend to photograph the front of the building next .... "in the morning light" .... in October if all goes to plan. Our little sunlight study says that's when it'll be best. You'll be able to see the front of one of the most unique buildings in Rhode Island and then spin around and see their eelgrass restoration project and the dock where the mighty Alita Morris revs her engines before delivering schoolchildren to an out of classroom educational experience they won't soon forget. It's all in the plan.

Fair Journey,

Brian Shriver

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,

Our Journey

We do panoramic photographs at aerialvr.com, sometimes aerial ones. It's a strange and exciting place to be. It's a relatively new technology that's been made possible by the advent of digital technology and of course by computers and the internet. It's already so good that the "vr" part (short for virtual reality) is hardly an exageration. It will only get better.

My journey began 6 years ago when I borrowed a digital snapshot camera with the notion of participating in a local art contest. I went to a pleasant spot with a view, aimed my camera at the horizon and took 10 images spanning 180 degrees of view. I took them home and printed them out on my home computer and then manually pieced them together with the aid of an exacto knife and some tape. I framed the resulting 7' long photograph and entered my contest. I took an honorable mention, for concept mostly. It was a little rough in the way of craft but it was still a panoramic photograph: a series of images brought together at their edges to create a larger one with an extremely wide angle of view, but without the usual distortion that wide angle lenses create.

It occurred to me then that someone might be doing digitally what I had done with my knife. I typed "panorama" into the internet and found some free software that would do just what I'd imagined. I loaded the software into my pc along with the 10 photos I'd taken and my pc promptly crashed, overloaded. A friend of mine doing digital photography on a much better computer was intrigued by my project and took it on. He completed it in short order and printed it out. It hangs in my living room to this day. It's still fun to look at.

Roll the calendar to 2009 and enter Christopher Blake. Chris had started a business doing digital panoramas and aerial photography several years back. Chris saw the panoramic photograph on my wall and began to share his own enthusiasm. He wanted someone to write a blog that might attract attention in the blogosphere, some web traffic and new business opportunities. He also needed someone to share photography duties. I signed up with gusto!

Chris' journey towards aerial panoramic photography really began in the early 1990's with hang gliding. Somewhere along the line he hung up his wings but must have missed his bird's eye view and began to ruminate on how he could recreate the experience without the hazards. His first idea was to mount a camera on the bottom of a radio controlled model helicopter. He wasn't the first to do this. It was an impressive machine with several horsepower and a 5' diameter rotor but he watched a fellow enthusiast and expert pilot crash one into the side of a house after the tiniest of mechanical failures and wondered if that was really how he wanted to hoist an expensive camera into the air. He decided to try something safer.

Chris bought a high performance kite that with a stiff wind could easily lift his camera off the ground. Actually, he lofted the kite part of the way into the sky, attached his camera to a little trolley of his own design and then let the line out. The kite went up and hauled the camera up after itself. The camera was set to take a series of photos on timer and despite the swinging and swaying about one of the shots was bound to be worth the effort. It was fun but it had serious limitations.

His next purchase was a 15' helium filled blimp. He hung his camera on the bottom of that and found a gadget that allowed him to trigger his camera remote control. The blimp was tethered and would orient itself to the wind so the next step was obvious. He had to spin the camera on a mount using a servo motor. Chris put his background in airplane mechanics, radio control devices and mechanical design to work and soon had a remote control robotic camera mount hanging from his blimp. It was too heavy to fly well but a bigger blimp solved that problem.

Not a bad rig! Chris was soon traveling to scenic spots around Rhode Island to fly his blimp and take photographs. At some point the technology for stitching digital photographs together into panoramas came across his radar and the notion for Aerial VR was born. Some of his early work entailed doing aerial panoramas for developers of tall buildings who were trying to market their view. Often it's not possible to fly an aircraft of any type under 500' altitude. The blimp is an attractive option. The pay scale is attractive too for that sort of work but it doesn't come along that often and good flying and photography days come along even more rarely.

We're approaching if not a "perfect storm" of events then a series of technological events that are making Aerial VR an exciting business proposition. Digital cameras have come a long way. A digital SLR can now slam away 10 or more beautifully focused megapixels of digital imagery several times a second. They are easily remote controllable, communicating to standard laptops over inexpensive equipment designed for cordless networking. Chris' blimp supported remote controlled robotic camera mount (bsrcrcm??) takes these amazing cameras safely up into the sky and points them in the right direction. Chris' next generation of robotic mounting equipment promises to be even more stable and accurately positionable and is likely to go into use this summer.

The storm isn't over yet. One has to consider what happens next to the digital data. State of the art stitching software puts all of the imagery together into a seamless panoramic bubble, or "panobubble" as we often refer to them. The next part of the problem is bringing the panobubble to the consumer of photographic delights and getting him to step inside the virtual reality it creates around him. High resolution panobubbles are data heavy. A company named KR Pano has created a viewer that runs on a standard pc. It allows the viewer to "point" himself in any direction and to zoom in and out. Zoom out to enjoy the panoramic view from horizon to horizon. Zoom in to practically count the whiskers on that squirrel perched on a branch hundreds of yards away. So the answer to the piles of data problem is to just shovel the part the veiwer has "requested" by adjusting the pan and zoom settings on his viewer.

Another company named 360Cities has adopted the KRPano viewer and perfected the art of streaming just the "requested" data over the internet. Now the consumer can enjoy virtual reality with nothing more exotic than a standard pc with a dsl type connection. The mighty (and mightily prescient) Google has recognized the potential of this technology and backed one its best providers at 360Cities.

Where does that leave us at Aerial VR? We're not sure. We're on a quest. We're on a quest for cool. We're looking for wow and we want to share it, our cool bird's eye view on the planet. Who might enjoy this technology? Who might decide they even need it? Who might benefit from it and what will they be willing to pay for it. Real Estate developers? Real Estate sales people? The tourist industry? The professor of architecture in the classroom? The virtual tourist or the tourist industry? We're not sure where our holy grail lies but one thing we're sure of, we intend to enjoy the journey in search of it and shoot some really fun photos on the way there.
