John Deere Tree Harvester

T-man says...

But we need lumber. There isn't a real alternative that I'm aware of. And people don't usually buy lumber to burn it or use it in a manner where it is going to decompose anytime soon. Isn't it usually used to make durable goods?

We just need to responsible in cutting it.

grinter says...

that doesn't look very good for the trees.

oh, and farming trees is a very inefficient/destructive way of fixing CO2. Photosynthetic plankton are much better at it. Besides, that wood will only hold it's CO2 for a finite time.. eventually it will burn or decompose. Ultimately, "let's cut down the trees to stop global warming" doesn't stop global warming, and leaves horribly disturbed forests, devoid of the usual diversity that we value in forests.
Here's a neat paper on using farmed plankton to fix CO2. I'm not advocating it; it's just a neat paper: link

Can you build a house with straw?

jwray says...

The reasons to not use straw bales are the same as the reasons people stopped using thach roofs & bare wood siding:

1. Millions of microscopic bugs & bacteria thrive in it.
2. It'll decompose quickly, because of those guys.
3. It's very flammable. This has caused chain reactions that burned down whole cities.

no, the meat was supposedly bad because it was such an old and tough boar, might be some truth to that, as animals generally taste worse the older they get, but hanging it up without field dressing it wasn't real bright either, as the guts will decompose and start to smell the fastest...

Top Gear - Hydrogen Powered Car made by General Motors

gluonium says...

please get a clue. you are not "extracting" energy from water to run this or any other hydrogen powered car. hydrogen can only be used as dgandhi points out, as an energy STORAGE mechanism as you will always have to input more energy into the process of splitting water into it's constituent gases than you can ever get back out of the process of recombining them into water. you put lots of energy into splitting water into H and O then you GET BACK a portion of that energy by recombining the H with the O (burning it). this is 4th grade science. to anyone who knows how the thing actually works it makes you sound daft to say the car is "running on water" or giving "free energy" just as it would sound daft to say that your current car "runs on CO2" because the plants that decomposed in the ground that turned to oil over millennia originally produced their hydrocarbons by using CO2 in the ancient atmosphere. sorry but this is the sort of thinking that physicist Wolfgang Pauli rightly calls "not even wrong".

Timelapse Decomposition of a Pig

Peter Greenaway: Windows (1974)

dotdude says...

Upvote for Peter Greenway. I rented "The Draughtsman's Contract" last.

I wonder if there are any clips from "Zoo" ("Two Naughts and a Zed") Sifters would probably like the time lapse sequences of decomposing animals.
