Updates to: Raven Rocks: The
Place and the Idea We bought Raven Rocks in 1970, so today, in 2001, we have spent more than 30 years happily at work here.
For ten years or so, we have planting a reduced number of trees each spring. Don Hartley estimates we now have 25,000 to 30,000 trees growing. We recently reached the decision that, due to changing circumstances-- chief among them the aging of our group--the trees we planted in the spring of 2000 will be our last. Even so, the present plantings will last nine more years. Raven Rocks, Inc. now owns 1,052 acres.
The alternative energy dreams and plans that we have nurtured more than twenty years have come true in almost unbelievable form and degree. Within the near future, two modern wind machines will be installed here, each a prototype that will test a different approach to harvesting the energy available in winds over the full range from poor, as ours are, to high quality. Each of these innovative designs is expected to bring significant improvements in cost, maintenance and productivity. Because the sun often shines when the wind isn't blowing, photovoltaic panels (PV) that convert sunlight into electricity can complement the wind machines. We are presently near completion of the first of four large solar arrays, each utilizing 26 panels to achieve an array size of 13 x 16 feet. In order to improve their productivity, by 40% in fact, the arrays will be equipped with state-of-the-art trackers that will keep them facing the sun from the time it rises to 15 degrees altitude in the morning till it falls below that level in the evening. Most exciting, perhaps because it has for so long eluded the grasp of persons who recognized its remarkable qualities, we are already deeply engaged in work that will equip us with the capacity to produce and to utilize hydrogen. We have made ourselves availableour site, our alternative energy systems, and ourselvesas a working lab to Proton Energy Systems for their development of hydrogen technologies as a means to store the excess electricity from the wind and PV. We are ownersproud ownersof a Hogen 30 electrolyzer, made by Proton, which splits the water molecule, using electricity, into its component parts, hydrogen and oxygen. The hydrogen, stored in high pressure tanks, will be available at those times when insufficient electricity is available from the PV or wind turbines. It appears now that we are only a hop, skip and a jump away from use of this energy to move our cars. For whatever application, a fuel cell, using a chemical process, will recombine the stored hydrogen with oxygen from the air, creating electricity again! And the byproduct of this electrochemical magic? Water. Only water! back to Raven Rocks home page |
