How Green is This?
August 23rd, 2008One of the conversations I overheard the other night was about a company in Israel that’s growing, out of “regular plants” - trees and stuff, furniture and houses and various whatnots. All part of the “Green Movement”, they claimed. Well, that one got me curious.
Turns out it is true, essentially. I found the source on the internet, just as the guy in the Café said. (Surprising, isn’t it, how many people - folks you’d never ever picture on a computer - are surfing the Web!) I found an article in ScienceDaily August 21, 08, titled “Eco-architecture could produce ‘Grow Your Own’ Homes.” There was a picture of a park bench built around, or integrated with, a couple (maybe 4?) trees. Actually, the bench was made of lumber like a regular bench but had trees growing in/through the ends of it. Made a pretty great shady rose-garden type thing, au natural, but not all that impressive. I’ve seen equally nifty, integrated-with-living-plants benches in grape arbors and rose trellises, even Mexican-style ramadas.
But reading on, I found hopes being expressed that were much more grandiose:
“Pilot projects now underway in the United States, Australia, and Israel include park benches for hospitals, playground structures, streetlamps and gates. ‘The approach is a new application of the well-known botanical phenomenon of aerial root development,’ says Prof Eshel. ‘Instead of using plant branches, this patented approach takes malleable roots and shapes them into useful objects for indoors and out.’” [This Prof Eshel was ½ the Tel Aviv U. team doing all his. The other is Prof. Yoav Waisel.]
Now as I read, I was reminded of something I’d seen before. There once was a California roadside attraction created in the 1920’s. I’d seen it in one of Huell Howser’s popular PBS travel documentaries, a series called California’s Gold.
A little googling freshened the details: A Swedish immigrant, Axel Erlandson started shaping, splicing and manipulating a variety of trees into all sorts of sometimes crazy, sometimes beautiful, sometimes utilitarian, and always “Wow!” shapes. After about 25 years of this he transplanted his marvels, about 70 in all, to Scotts Valley, California, and turned the collection into a roadside attraction for motoring tourists. The Tree Circus, he called it. He’s gone now, and so are some 2/3 of his trees, but the survivors have been incorporated into a “theme park”, called “Bonfante Gardens”.
My googling exercise also revealed there are dozens of other similar attempts to do what this Israeli team (and corporation) are doing, not to mention a variety of patents on tools and processes to do it. So there’s not as much new and original here as ScienceDaily or the Israeli pair think there is. They say:
“The original ‘root breaking’ research was conducted at the Sarah Racine Root Research Laboratory at Tel Aviv University, the first and largest aeroponics lab in the world. Founded by Prof. Waisel 20 years ago, the lab enables scientists to conduct future-forward and creative research that benefits mankind and the environment…” and express hopes that this “new method for growing ‘soft roots’, which could easily turn living trees into useful structures …. in the near future, entire homes will be constructed with the eco-friendly technology. An engineer by trade, Plantware’s CEO Gordon Glazer hopes the first home prototype will be ready in about a decade. While the method of ‘growing your own home’ can take years, the result is long lasting and desireable especially in the emerging field of green architecture.”
I hate to rain on anyone’s parade, but I have to at least toss a bucket or two of skepticism on this one. First, there’s obviously nothing all that new or original here. Maybe no one else is actually working on the roots, as opposed to the rest of the trees, but so what? Second, What’s so “green” or “eco-friendly” about growing a bench or staircase (as Erlander did) instead of making it out of lumber from trees you grew for the lumber? And last, maybe you could grow a whole house, but how is even that worth anything but the extra novelty? And I don’t about you but I have no interest in buying a house that I have to wait so long to have it finished that I’ve paid off the mortgage (and rented all the time while doing it) before I can even move in!
