I find myself sounding like an advocate for the parking machine I described, which is known as Safepark. I do not have any financial connection to them tho I admit I kind of like this older fellow Bill Sternad who developed it over the last 13 years. He seems like a guy on a mission to prove his mouse trap is better. Another disclaimer seems in order in light of recent comments here, I am reluctant to urge accomodation to the automobile. Many know me as an anti-automobile person. Our household's second vehicle is a bicycle (or 2 or 3 or). I like the suggestion of having a cohousing community being a node in a car sharing system. And finding alternate uses for required parking lots sounds great to me. Our household uses the driveway and garage off the alley for their intended use in the Minnesota winter but other seasons we park on the street and use them for bicycle parking, garden storage, staging area, sail boat maintenance etc. But at this time parking for cohousing is a necessity. I liked Casey Morrigan's <cjmorr [at] pacbell.net> words: > It is hard to live in the dilemma of wishing we didn't need cars, but > needing realistically to plan for their use. It is an example of how > ideals collide with reality in designing cohousing. I think making the costs of automobile use more explict - like paying for parking rather than let it be lumped in and sort of hidden in land costs - may make its real inefficiency and cost more apparent and bring the day of a more rational mix of transportation closer. Tho it is not a cohousing joke, I'll pass on the words from an interesting WW II poster that is in sharp contrast to today's policies.

The Safepark machine for 62 cars is around $10,000 per space, but is much more efficient in surface area devoted to parking.

I did not study them in detail to see how they compare. I did ask Bill, the developer of the one I described, how they compare and he said that his Safepark machine is distinguished by its simplicity and therefore reliability. It has just two hoists and four pneumatic cylinders to accomplish the stowing and retrieval of cars. Bob Morrison <bomorris [at] cisco.com> wrote: > A concern I have is that people could lose the use of their cars if > there is a long power outage. The Safepark system is designed for reliability and uses a hybrid power system which will function much like the gas-electric cars (Prius and Insight). A built-in gas or diesel generator will power a 50 KW generator to charge batteries that power the 125 hp motors of the hoist and air compressor for the pneumatic cylinders. The lowering of cars does some charging as well. The low duty cycle (low percent time lifting cars) works well with this system. Another detail that came up talking to Bill is that when the cost of land is $50 per square foot or greater building a Safepark machine would be cost effective. I've developed a bit better understanding of the machine and offer this explanation. Look at the image at http://3dok.com/carpark with this description. There is a hoist shaft at each side and room parking for 4 cars side by side between shafts (except first level) cars on a given level all move left or right together. The following diagram depicts the steps (left to right) that I imagine to retrieve car 2. (where each digit represents a car, each line represents one level - not all levels shown; diagrams show resulting state after described (in words) step). Underscore "_" represents a vacant spot: _1234_ 1234__ _234__ _234__ _5678_ _5678_ 15678_ _15678 _9abc_ _9abc_ _9abc_ _9abc_ initial 1 left 1 down 8 right _234_8 234_8_ _34_8_ _34_8_ _1567_ _1567_ 21567_ _1567_ _9abc_ _9abc_ _9abc_ 29abc_ 8 up 2 left 2 down 2 down 2 down repeatedly to bottom. (Note there may be a more clever way, that for example does not leave vacant spot between 4 and 8.) Fred -- Fred H.
