Tasty Exhaust Fumes

BenzFor the last 2 weeks, my Mechita has been running on B30 (a blend of 1 part biodiesel to 2 parts normal petroleum diesel), blended by pouring the biodiesel directly into the tank and with no modifications to the engine whatsoever. The B30 is enough to produce a strong aroma of french fries, characteristic of cars running on biodiesel produced using waste vegetable oil (WVO) as the feedstock and certainly beats the noxious odour of pure petroleum diesel.

Ideas for Extensions to Eco Home

HouseAfter a good 20 months in my small adobe cottage at Lynedoch EcoVillage and having witnessed all manner of architecturally uninspired monoliths spring up around me as a result of a poorly planned housing development at the village, I am exploring options for an ecologically built monolith of my own. I have used a 3D modelling programme called Sketchup to present my initial ideas.

Check out the Chicken

Solar CookerSince becoming aware of their existence, solar cookers have always intrigued me. Yet I have to admit to having previously harboured a certain degree of scepticism as to their efficacy and practicality. A visit to some friends a week ago, where I witnessed a solar cooker performing some low level bean-cooking, had the effect of upgrading my intrigue to full bodied consumerism (with an ecological slant thankfully) which I acted upon...

Visit to Hammarby Sjöstad, Stockholm

TramMy participation in the Building and Social Housing Foundation's study visit to the Solar Houses in Gårdsten, Göteborg, afforded me the opportunity to catch the X2000 high-speed tilting train (an experience in itself) to Stockholm where I spent an afternoon rambling around Hammarby Sjöstad, a high income urban development incorporating numerous sustainability related innovations. I felt at times like I was in some sort of futuristic movie. Pictures that I snapped of some of the features follow...

Biodiesel Benz

MechitaThe first week of spring heralded my taking ownership of a W123 Series Mercedes Benz 300D, the icon of the veggiemobile movement. She (for she is a she) is a 1985 model with a seemingly undercounted 323 000 odd kilometres on the clock.

The Struggle Against Ourselves

Climate Change MarchAfter the hints of optimism that emerged from the UN Climate Change Conference in Montreal earlier this month, it might be apt to revisit the somewhat poignant ending to George Monbiot's speech delivered at the Climate Change march on the 3rd of December lest we forget where the real struggle lies...

Ecological Footprint

According to my ecological footprint calculation at Earthday.Net, if everyone on this planet were to to live the equivalent lifestyle to me, we would need 2.4 planet Earths to sustain us all.

My personal footprint takes up 4.3 hectares which coincides with that of the average South African. It should be noted however that South Africa is one the most unequal societies in the world (along with Brazil) with a disproportionately large disparity between the haves and have nots.

To live a supposedly sustainable and ethical lifestyle, my footprint size would have to decrease to 1.8 hectares as that is how many globally productive hectares are available per person at current population levels.

My footprint is made up as such (in hectares):

Food 1.2
Mobility 0.9
Shelter 0.5
Goods and services 1.7
Total footprint: 4.3

My ecological footprint before moving into my ecologically built home at Lynedoch was 6.7 hectares...some improvement, but still a long way to go to one planet living.
