Archimedean Energy Storage

mechanical battery“Forget batteries with complex chemistries or precision-tuned flywheels. A growing number of energy storage start-ups are promoting the idea that the most economical, most expedient ways to store power revolve around harnessing the four elements of the ancient world: earth, air, water and fire.”

Fences, Gates and Bridges

fences gates and bridges“It is authoritatively stated that the building and maintenance of the farm fences in the United States have cost more than the construction of the farm buildings. Be this as it may, while large numbers of works have been written upon rural architecture we believe this is the first publication specially devoted to Fences, Gates and Bridges.

It aims to be a practical work, showing the “evolution” of the fence from the road barrier of logs, brush or sods to the latest improved forms of barbed wire. The numerous illustrations are mainly representations of fences, gates, etc., in actual use. The chapter on fence law is necessarily condensed. The various judicial decisions upon the subject alone would fill a large volume. This little work, the first and only one of its character, is given to the public in the confident hope that it will prove specially useful to farmers and village residents.”

Satisfying the builder’s need for the creature comforts of home, it also provides tips on how to build hearths and chimneys, notched log ladders, and even how to rig a front door with a secret lock. Illustrated throughout with a bounty of helpful line drawings, Shelters, Shacks, and Shanties harkens back to the can-do spirit of the American frontier that still thrives today.”

The Full Moon Theatre

moonlight theatre

Under good climatic conditions and using specific technology, the full moon can be a powerful source of light.

Using technology inspired by solar energy concentrators, the “Full Moon Theatre” lights its performances using only moonlight. Moonbeams are collected, concentrated, and focused on stage.

The original Full Moon Theatre was built in Southern France and their plan is to create twelve Full Moon Theatres worldwide.

A Mattress that Lasts a Lifetime

mattress that lasts a lifetime

“Our mattress is worn out. We need a new one, but I’ve been dreading buying a new one. I don’t like the waste of it all: The ignoble dragging of the old mattress to the curb. The prospect of sleeping on a brand new construct of toxic foam and fire retardants… In Greece, Italy and France mattresses are made by local craftsmen, and are stuffed with 100% wool. These mattresses basically last for life. When the wool gets compressed the mattress guys will empty it out, fluff it up, and re-stuff it, adding more wool if necessary.” [1]

“The bed Mary bought was made by Signor Oldani, a Milanese bed-maker and upholsterer. He made beds the Italian way, and the way we used to make mattresses in England before the introduction of short-lived internally sprung ones.

The beauty of the mattress is that when it needs a wash, the wool can be pulled out, stuffed, in batches, into pillow cases, put through the washing machine and after drying, carded back into fluffy pile before being returned to the mattress cover.

Every few years, it needs to be re-carded, as the wool slowly compacts, says Mary. In Italy during the summer, the mattress man, il cardatore, tours Italian homes, pulls out the wool from their mattresses, re-cards it, adds some more, as the process reduces the stuffing a bit, rebuttons and then sews the mattress cover back up again. Mary submitted her mattress to this process four times.” [2]

“Totally by chance, I found two places in Paris that still make their own 100% wool mattresses by hand… It was ready two days later. They told me to come back in 10 years to have the mattress redone: they pick it up in the morning, take out the wool stuffing, clean and refluff it, put a new cover on it, and then deliver it back to you before bedtime.” [3]

The Religion of Complexity

“The reaction of most people when I tell them I’m a scythe teacher is the same: incredulity or amusement, or polite interest, usually overlaid onto a sense that this is something quaint and rather silly that doesn’t have much place in the modern world. After all, we have weed whackers and lawnmowers now, and they are noisier than scythes and have buttons and use electricity or petrol and therefore they must perform better, right? Now, I would say this of course, but no, it is not right. Certainly if you have a five-acre meadow and you want to cut the grass for hay or silage, you are going to get it done a lot quicker (though not necessarily more efficiently) with a tractor and cutter bar than you would with a scythe team, which is the way it was done before the 1950s. Down at the human scale, though, the scythe still reigns supreme.”

Scythe“A growing number of people I teach, for example, are looking for an alternative to a brushcutter. A brushcutter is essentially a mechanical scythe. It is a great heavy piece of machinery that needs to be operated with both hands and requires its user to dress up like Darth Vader in order to swing it through the grass. It roars like a motorbike, belches out fumes, and requires a regular diet of fossil fuels. It hacks through the grass instead of slicing it cleanly like a scythe blade. It is more cumbersome, more dangerous, no faster, and far less pleasant to use than the tool it replaced. And yet you see it used everywhere: on motorway verges, in parks, even, for heaven’s sake, in nature reserves. It’s a horrible, clumsy, ugly, noisy, inefficient thing. So why do people use it, and why do they still laugh at the scythe?”

“To ask that question in those terms is to misunderstand what is going on. Brushcutters are not used instead of scythes because they are better; they are used because their use is conditioned by our attitudes toward technology. Performance is not really the point, and neither is efficiency. Religion is the point: the religion of complexity. The myth of progress manifested in tool form. Plastic is better than wood. Moving parts are better than fixed parts. Noisy things are better than quiet things. Complicated things are better than simple things. New things are better than old things. We all believe this, whether we like it or not. It’s how we were brought up.”
