Wood

The 180 Stove is a simple, portable backpacking stove that relies on wood as its sole fuel. Unlike gas canisters and liquid propane, wood is a natural fuel that's available in all types of wilderness areas, making it a renewable, clean source of fuel for backwoods cooking. And since there are no canisters to buy, carry and dispose of, you save weight and space in your pack.  Read More

Earlier this week, we brought you the story of a radiologist and two violin-makers, who used computed tomography (CT) imaging to create a copy of a 1704 Stradivarius violin. The instrument that they produced was almost an exact replica of the original, as far as the shape, thickness and volume of its wooden parts was concerned. As one of our readers pointed out, however, much of the tonal quality of Stradivari's instruments was likely due to the microstructure and resonance characteristics of the wood of which they were made, caused by the growing conditions at the time. Well, it turns out that someone is working on reproducing that aspect of the violins, too.  Read More

When choosing wood for applications such as load-bearing beams in houses, it's important not to use pieces that contain cracks or other defects that could affect their structural integrity. While not quite as crucial, it's also nice to avoid flaws when building things like wooden furniture, piano soundboards, or window frames. Typically, people have been limited to visually checking the wood for such defects. Now, however, researchers at Germany's Fraunhofer Institute for Wood Research have developed a system that highlights faults invisible to the human eye, using a process called high-power ultrasound thermography.  Read More

Whether it’s the Renovo/Audi duo lineup, the just-announced Lagamorph, or one of the various bamboo creations, wooden-framed bikes (or in the case of bamboo, “wooden”-framed) are becoming more and more popular. While this is partly because of the ride characteristics and eco-friendliness of sustainably-harvested wood, let’s be honest – it’s mostly because they look nice. Unfortunately, they also tend to be pricey, with a single complete bike costing several thousand dollars. Well, if it’s just the aesthetic of wood that you want, now you have an alternative ... New Zealand’s Rob Pollock will give your frame a hand-painted woodgrain finish, for just US$1,500.  Read More

When established furniture maker Seth Deysach was invited to be part of the Object Society design show in June last year, he decided to create something special for the occasion that combined two of his passions - creating things in wood and cycling. The single-speed, one size Lagomorph bike boasts strong, elegant lines and an impressive catalog of high quality components. Now the designer is taking special orders for the wooden-framed bike, with custom options available on request.  Read More

Ethanol is the most commonly used biofuel worldwide and is made by fermenting the sugar components of plant materials, usually sugar and starch crops such as sugar cane, corn and wheat. The difficulty in accessing the sugars contained in woody biomass, coupled with criticism that the use of food crops for biofuel production has a detrimental effect on the food supply has prompted research into biofuels that can be made from cellulosic biomass, such as trees and grasses. By looking at the digestive system of termites, researchers have now discovered a cocktail of enzymes that unlocks access to the sugars stored within the cells of woody biomass that could help make it a more viable source of biofuels, such as ethanol.  Read More

There was also a time when wood was relatively cheap and plentiful in much of the world thanks to the number of trees just standing around waiting to be turned into useful things like floorboards. Unfortunately wood is neither as cheap nor plentiful as it once was, so it’s important to make the most of every tree. Instead of following the traditional line of straight-edged floorboards, Dutch company Bolefloor maximizes the coverage area of floorboards made from a particular tree by following the tree's natural curves.  Read More

It has been estimated that up to 85 percent of all wood materials (such as particleboard or plywood) contain adhesives that in turn contain formaldehyde, and the World Health Organization has classified formaldehyde as a carcinogen. Unfortunately, it’s not enough to simply avoid eating those wood products – even the fumes given off by formaldehyde have been shown to pose a health hazard. Many people turn to keeping spider plants in their homes or offices, as they help neutralize airborne toxins, but now help could be coming from another source. German researchers have discovered that by adding special minerals to wood adhesives, those adhesives themselves can help clean the air.  Read More

Using a hand saw is nobody’s idea of a good time, but one inventor is trying to at least make it a little easier. John Zimmerman, a software developer by trade, has created what he calls the Recoil Saw. Essentially, it’s just a saw – various types of saws, actually – with one or more spring-loaded impact bars attached to the blade. At the end of each stroke, the spring compresses as the bar hits the material being sawed, then releases that energy back into the following return stroke. The idea is that users can pretty much just bounce their way through cutting jobs, as opposed to having to purposefully stop and start between every stroke. Zimmerman, who admits he’s probably not the most unbiased tester, said that he has found it cuts twice as fast as a regular saw.  Read More
