Halt all expansion of airports, & ban short-haul flights

"The Plane Stupid! agenda has two other demands: halt all expansion
of airports, and ban short-haul flights."

We Should All Be At Heathrow Protesting - It is collective pressure on government, not consumer choices, that the world needs now.

by Johann Hari

This week, two thousand people will gather at London’s Heathrow airport with tents and sleeping bags - not to EasyJet to the beach, but to alert their fellow citizens to the Weather of Mass Destruction we are unleashing.

If you need to know why this is necessary, take a look at the world the deniers are so glibly averting their eyes from. The two countries doomed to drown by global warming in my lifetime have already begun to disappear beneath the waves. Almost half of Bangladesh is under water as you read this, following monsoons four times more ferocious than they should be. Ten million people are now homeless in the
region. In the Maldives, a series of massive swell waves stretching to 4.5 metres drowned 68 islands this spring. The residents know the waves are getting bigger every year, and soon they will swallow their homes forever...

TrashTrain Praha 1/12


This is a concept for an all-electric & human-powered logistics system for Prague... it's called TrashTrain BUT it's much more than that...

... cities all over Europe (well, Western Europe, so far) restrict (not just) delivery vehicles based on their emissions. See plan for London ... Milano will be implementing something similar starting in 2008.

Of course it is certainly not just about emissions! The most recent - and exciting - development in what I call "street de-chaosification" AND emissions-free logistics is in Amsterdam, with City Cargo . See longer video here . In Switzerland electric vehicles have been used for years in the mountains, and there are also cargo trams in Zurich.

For more innovative concepts in urban logistics check out Bestufs .

Energy Use Rant

"Lance Armstrong pedalling a bike-driven generator can
produce about 350 watts and he can probably keep this
up for about 3 hours. That is, roughly, 1 kilowatt-hour.

If Lance drives to the gym in a Prius and he travels
10 miles round trip, he uses an average of about 10 HP
for a period of 10 minutes (assuming an unlikely average
speed of 60 MPH). At 746 watts/HP, this is 74,600 watt-min:

10 min * 10 HP * 746 watts

74,600 watt-min is 1243 watt-hours or 1.243 kWh

So, in ten minutes of driving, Lance uses more energy than
he can produce in 3 hours of pedalling.

Now, if it's YOU on the treadmill, how many watts continuous
can you produced for three hours?

If you power your car by pedalling a generator to charge
its batteries, you're going to have to pedal for, say,
one working shift in order to drive 10 miles back and
forth to work. Or, you could ride your bike for, say,
40 minutes each way.

We MUST get our heads around the notion of just how much
energy we are consuming. It's truly incredible. Think in
terms of reducing your energy consumption 10-fold in
your lifetime. Even THAT is probably not sustainable.

The fix we're in is so much worse than people think it is,
simply because they think it's quite normal to put 10 gallons
of gasoline in the car once or twice a week. The energy
content of that gasoline is just incredible; only since
the start of the industrial era have people been able to
consume energy at this rate. This has only been possible
because we have been burning fossil fuels created over a
span of millions of years during the course of a century...

...Life is going to change. Get used to it. Then figure out
how to enjoy it. That's not hard. Just imagine carfree cities."
