Soon the self-driving car

I think it is safe to write that everybody just hate traffic congestion which combines wastes of time, money and energy on top of being helpless. The dream of ultimate mobility offered by cars is often transformed in cities as an immobile nightmare. Given how Google has mapped the Earth and how computers have gain … Read more

Computing for sustainable water

Last week the World Community Grid announced it was launching a new project that directly caught my attention, called Computing for Sustainable Water. As the article I received in my mail stated : ” Researchers at the University of Virginia are running the Computing for Sustainable Water project to study the effects of human activity … Read more

Engineers discover self healing circuits

To Ecogeek : “ A team of engineers at the University of Illinois have figured out how to create self-healing circuits in electronics and batteries, a discovery that could lead to longer equipment life ” ” As electronics have become more complex, one small circuit failure can render a device useless, especially since it is hard or often impossible to … Read more

Great technologies for our computers

To Clean Technica : Samsung has developed a new computer that is solar-powered! The Samsung NC215S netbook it will be the first computer of its kind. The power will come from a solar panel embedded in the lid. “ Still to Clean Technica :

” a team of researchers at Australia’s RMIT have demonstrated a new, “nano-scaled” piezoelectric film’s capacity for turning mechanical pressure into electricity — bringing the  dream of perpetually-charged laptop batteries one giant leap closer to reality. “

I look forward to seeing these innovations in my next laptop or iPhone. It seems I am always recharging them… With both technologies combined, we would have virtually endless batteries.

Do computers outpace cars as vehicle of self-expression ?

As a young urbanite, I don’t own a car. Indeed, cars are very expensive nowadays – with oil costing more than 1.50 euro per liter, or $8 a gallon – and public transportation make it quite easy to ditch your car in Paris.

However, I own a computer. I believe it is making a statement about me as I carefully chose each component and assembled them all by myself.  I now have a silent and nice computer that consumes little energy on my desk at home.

Even if I wouldn’t turn down an offer for a Ford Gran Torino (pictured above, ala Starsky and Hutch) or a 1970 Mustang (sorry for the clichés), I don’t need a car, I don’t want a car.

Graphene can be produced by sugar

I once wrote that aerogel – a great insulating material, 37 times more insulating that fiberglass – can be made of rice husks, a common byproduct of the most eaten cereal in the world. Now it seems that graphene – a highly conductible and resistant material that could literally revolutionize electronics and computers – can … Read more

Recycling by the numbers

The New Ecologist proposes a series of interesting figures on recycling. Here are some of them : The recycling industry is worth $160 billion and employs globally 15 million people.

Recycling aluminium needs only five percent of the energy needed to mine and refine the same quantity of new aluminium. The top 5 recycling countries are Switzerland, Austria, Germany, the Netherlands and Norway.

20 million tons of electric waste are thrown away each year. One ton of scrap from discared computers contains more gold than can be produced from 17 tons of gold ore.

The huge potential savings of small changes

This week I read an article from GreenTech Media titled When sleep saves.  This shows that a single company is due to save $400,000 (290,000 euros) this year just by putting all its computers in sleep mode when possible.

I am amazed at how such a simple thing can save so much money. If such a thing was generalized among all companies around the world, the savings would be staggering.

Around the world, hundreds of coal-fired plants are spewing huge amounts of carbon dioxide and other pollutants for nothing. It is high time we tackle the issue.

Shuting down PCs at night could save billions

1e-pc-energy-reportAn article on TreeHugger caught my attention as it explained that half US employees – and similar figures in other countries – don’t turn off their computers at the end of their work day. The potential savings are impressive.

In America: $2.8 billion, in the United Kingdom $420 million and Germany $1.2 billion. That’s right, turning off computers at night in these three countries alone could save $4.4 billion per year.

As more and more companies are willing to cut costs and outgreen their competitors, it’s high time to switch off both lights and computers at night.
