Man Grows Furniture, Art From Living Trees

- Benny Powers

It’s called arborsculpture, and Richard Reames has been doing it for years. He plants trees in patterns, and uses bending and grafting techniques to form the saplings into benches, staircases, sculptures, and an assortment of other amazing living things.

I believe that if enough people put their minds to using living trees, we can learn to grow houses. I believe that if we put our minds to it, like going to the moon, there’s no reason we couldn’t all be living in houses where the walls and ceilings are composed of living tree material and there are leaves coming out of the roof. We could accomplish this in one generation. We’d build doorways and windows that the trees would grow around, and also plumbing and electrical conduits. The trees would just swallow all the pipes. We’re going to call this “arbortecture.”

A New Way to Produce Coal From Biomass

- Cam Proctor

Good news from Germany!
Markus Antonietti from Max Planck Institute of Colloids and Interfaces has devised a chemical process that converts biomass like leaves, pine cones and other plant residue into wet coal (coal + water). Biomass goes into the autoclave, a kind of pressure cooker, water goes in, too, along with a citric acid catalyst. A chemical reaction takes place and coal is produced.

The single major by-product of the reaction is water, which can be filtered off. In contrast to other biomass techniques this reaction does not generate carbon dioxide. It also gives a higher energy product, which even smells acceptable.

We underestimated this when we started. We could calculate how much energy was stored in the sugar – in the leaf material. But the first time – as you see – we had a runaway reaction, which is obviously dangerous, so we need to carry it out under safe conditions.

See Solar Run

- Cam Proctor

A Drawing of the Sun from the USA EPA siteA solar cell absorbs a small range of light wavelengths based upon the density and width of silicon crystals. Light strikes the crystals and causes electrons to propagate along the network. We call this flow of electrons electricity.

More crystals of different widths in the network mean that more different wavelengths can be absorbed and more power can be generated. Adding different layers of crystals to absorb a wider range of wavelength is one way to increase the power, but the process to spread these crystals over a surface is very expensive and energy intensive.

Prism Solar Technologies is going a different path by splitting the incoming sunlight and concentrating specific wavelengths onto a variety of cells designed to collect those specific wavelengths, yielding 25% greater electricity yields. These concentrators and splitters are orders of magnitude cheaper to produce than solar cells and increase the power of each solar cell. Oh, by the way, the Prism splitter is clear.

Super Efficient House Uses 800 Watt Hours/Day

- Benny Powers

The Treehugger website is running some good news on an ultra-efficient model home.

This house has the conveniences of a modern house, but consumes only 800Whr on average per day. Compare this to a typical U.S. suburban house that uses 45 kilowatt hours (kWh) per day. How is this reduction possible? It’s through the strategic use of ultra-efficient appliances, daylighting, and green design principles for temperature control and ventilation.

The house also automatically turns off computer peripherals when not in use.

Google Does Good

- Adam Clare 1 Comment

Some recent news about that massive search engine Google. The company has announced that it has joined a US lobbying group, the ODF Alliance, that supports the Open Document file format. Open Document is a Free (as in free speech) document format, an alternative to the standard Microsoftâ„¢ .doc format. It is nice because it allows for a more accessible document than propriety software formats.

Having Google throw it’s weight behind supporting ODF will hopefully have a positive impact on the adoption of the open file format. ODF is also supported by Sun Microsystems, IBM and Novell, among others.

Google has also decided that they want to try to save the world with their vast wealth through their charitable organization Google.org. Wired has a nice interview with the man who is in charge of this billion dollar initiative from Google.

Google makes Adsense, which we use here at ThingsAreGood.
