Sustainability guru promotes lighter roads

The average temperature of central Sydney has risen 7.3% from 20 to 22 in 149 years.
Speaking to about 100 infrastructure professionals and in particular council planners from across the city, he promoted the idea of using pale gravel “so the gravel shows through the bitumen,” to make lighter coloured roads.
Mobbs said, “We could use dyes like those used in bus lanes, but paler than green or red. These were first used in the Harbour Tunnel, which was privately owned, because the owners wanted to cut the cost of their electricity bill. On streets with low traffic volumes these dyed surfaces will last 10 to 15 years.”
As the Sydney Morning Herald reported, planners have started listening to Mobbs, because he has transformed his own house into one with self contained power, water and sewerage systems.
Now he is converting his street, Myrtle Street, Chippendale, less than 2km from the centre of the CBD, so that much of the pavement is covered in mulch and supports a variety of plants including fruit trees. As well pipes have been relocated to retain rainwater and big bins to compost food waste brought on site.
