What is Low-tech Magazine?
Founded in November 2007, Low-tech Magazine questions the blind belief in technological progress, and talks about the potential of past and often forgotten knowledge and technologies when it comes to designing a sustainable society. Interesting possibilities arise when you combine old technology with new knowledge and new materials, or when you apply old concepts and traditional knowledge to modern technology.
My personal favourite articles:
Research shows that it’s possible to grow warmth-loving crops all year round with solar energy alone, even if it’s freezing outside. The solar greenhouse is especially successful in China, where many thousands of these structures have been built during the last decades.
For being such a seemingly ordinary vehicle, the wheelbarrow has a surprisingly exciting history.
Make a raised bed
Prepare the soil
Rhubarb prefers a sunny site and should not be harvested in the first year. Three crowns should be enough to feed a family. Once mature the crowns can be split to provide new healthy plants.
What are my responsibilities as a riparian owner?
- To pass on water flow without obstruction, pollution or diversion that would affect the rights of others.
- To maintain the banks and bed of the watercourse (including any trees and shrubs growing on the banks) and any flood defences that exist on it.
- To maintain any approved structures on their stretch of the watercourse and keep them free of debris. These may include trash screens, culverts, weirs and mill gates.
- Riparian Owners must not build new structures (for example a culvert, bridge or board walk) that encroach upon the watercourse, or alter the flow of water or prevent the free passage of fish
How do I maintain the watercourse?
a) Keep growth of vegetation (trees, weeds, reeds, grass etc) under control
b) Keep watercourses free of debris (e.g. litter, grass cuttings, and fallen trees and branches)
c) Remove excess silt

Or, a vision in a dream. A Fragment.
In Xanadu did Kubla Khan
A stately pleasure-dome decree:
Where Alph, the sacred river, ran
Through caverns measureless to man
Down to a sunless sea.
So twice five miles of fertile ground
With walls and towers were girdled round;
And there were gardens bright with sinuous rills,
Where blossomed many an incense-bearing tree;
And here were forests ancient as the hills,
Enfolding sunny spots of greenery.
But oh! that deep romantic chasm which slanted
Down the green hill athwart a cedarn cover!
A savage place! as holy and enchanted
As e’er beneath a waning moon was haunted
By woman wailing for her demon-lover!
And from this chasm, with ceaseless turmoil seething,
As if this earth in fast thick pants were breathing,
A mighty fountain momently was forced:
Amid whose swift half-intermitted burst
Huge fragments vaulted like rebounding hail,
Or chaffy grain beneath the thresher’s flail:
And mid these dancing rocks at once and ever
It flung up momently the sacred river.
Five miles meandering with a mazy motion
Through wood and dale the sacred river ran,
Then reached the caverns measureless to man,
And sank in tumult to a lifeless ocean;
And ’mid this tumult Kubla heard from far
Ancestral voices prophesying war!
The shadow of the dome of pleasure
Floated midway on the waves;
Where was heard the mingled measure
From the fountain and the caves.
It was a miracle of rare device,
A sunny pleasure-dome with caves of ice!
A damsel with a dulcimer
In a vision once I saw:
It was an Abyssinian maid
And on her dulcimer she played,
Singing of Mount Abora.
Could I revive within me
Her symphony and song,
To such a deep delight ’twould win me,
That with music loud and long,
I would build that dome in air,
That sunny dome! those caves of ice!
And all who heard should see them there,
And all should cry, Beware! Beware!
His flashing eyes, his floating hair!
Weave a circle round him thrice,
And close your eyes with holy dread
For he on honey-dew hath fed,
And drunk the milk of Paradise.

Stove fans are used to improve the circulation of heat which in turn reduces hot and cold spots throughout the home.
It doesn’t have any batteries so how does it work?
The stove fan is powered by the Peltier effect. This effect is due to a temperature difference by transferring heat between two electrical junctions.
The thermoelectric circuit is generated since it is composed of materials with different Seebeck coefficients. This is due to the junctions being made of doped* semiconductors.
In a Peltier fan the configuration is that of a thermoelectric generator.
*Doping is the intentional introduction of impurities to modulate electrical properties
RED Gardens Project, (Research Education and Development) consists of 6 family scale gardens each one 100m2 (1000sqf) and following a different methodology, or approach to growing vegetables. There is also a larger Black Plot, of about 1000m2 (1/4 acre) which is exploring issues and possibilities of an intermediate scale growing space.

Whispers the o’erfraught heart and bids it break.”
