Cradle of the best and the worst

I am on holiday with my family in Nevada and California, and while shopping for beer and clothing in Las Vegas, I was reminded of the words of Leonard Cohen:

It’s coming to America first.
The cradle of the best and the worst

Lenny’ was speaking of Democracy,  but I feel that the phrase can be extended into environmental, technological and cultural realms. And in his blog I wanted to record a few thoughts about the ‘best’ of the things I have seen.

Amidst the hyperbolic kitch of Las Vegas, we stayed in the walls of a gigantic hollow pyramid that is a truly astounding architectural and engineering achievement. For example, the elevators obviously cannot run vertically but instead run at angle along the slanted edges of the pyramid.

Housed underneath this beautiful roof were any number of gaudy distractions. But amongst them was the Bodies exhibition. I found the exhibition dignified, tasteful and astonishingly  educational. I left with renewed wonder at my body.

We visited the Hoover Dam in which the barely mentioned reality is that the water levels are running low. But there is no denying the engineering genius and boldness of the ambition behind it’s construction.

The Ivanpah Solar Power plant may be on the wrong-side of a historic divide between solar photo-voltaic and solar thermal. But the engineering is awe-inspiring: three giant towers concentrating solar energy – one resource which is not in short supply in this part of the world.

In Los Angeles we have used the excellent public transport rail system, which is easily accessible and welcomes bicycles. Over long stretches it has been built to use the inner lanes of freeways or major roads to minimise construction costs. And nearly all the buses have bicycle carriers attached to their fenders.

Many freeways have car pool lanes – in which only cars with more than one passenger may travel. Some freeways use a road pricing system –  long-discussed in the UK – in which the price to use a ‘Fastrak’ lane changes minute by minute – reaching peaks of 10 times the minimum charge at times of peak congestion. These lanes also allow fast buses to speed public transport as advertised in this excessively positive advertising video.

Of course road traffic defines LA. But driving speeds are slower in suburban streets  than in the UK’s narrower and more congested roads. In the suburban area of LA in which we are staying (El Segundo) traffic is dramatically better than Teddington.  And contrary to myth, there is excellent provision for pedestrians. And of course, California is a world-leader in legislation to control vehicle emissions.

The Hollywood Bowl

The Hollywood Bowl  is aunique cultural venue combining excellent music with the  friendly ambience of the proms and the ability to picnic as the Sun sets over the Hollywood Hills.

Culturally, the Getty Centre and Villa, the California Science Centre  (which houses the space shuttle Endeavour) and the Griffiths Observatory are among the best museums I have ever visited. And they are free.

The Disney Theatre is breathtaking and the Hollywood Bowl provides a venue for music that is unique – it felt like ‘the Proms with picnics’

The Griffiths Observatory looks over LA like a modern day secular temple to the stars.

So forgive me if I pass on reciting the sins of this resource-gobbling satan. In this ‘cradle’along with ‘the worst’, are some things that I find inspiring and well-worthy of the epithet ‘the best’. And I hope that like many Californian innovations – such as vehicle emission limits – many of these will leave this cradle and spread around the world.

And to my friends: forgive me if I forgive myself for this carbon-heavy holiday.

Rocket Boys

April 12, 2012

On a previous visit to California, I introduced my friends to the thrills of launching water rockets. On this visit, they returned the favour by introducing me to chemical rockets. It was every bit as enjoyable as water rockets with the added frison of danger, especially when launching on the beach under the flight path from LA International Airport.

Rocket Engine

The internal structure of a rocket engine. After ignition, the fuel burns and the ejected hot gas drives the rocket forward. After a delay a second charge blasts the top off the rocket, releasing the parachute. (Click for larger version)

The rocket bodies were simply cardboard tubes, but the rocket ‘motors’ are ingenious. They are built into a cardboard tube, like a firework, and contain an electrical ignition ‘fuse’, rocket fuel, a ceramic nozzle to channel the hot gases, a delay element, and a second charge which blows the top off the rocket and releases the parachute. Very clever.

If you haven’t read ‘Rocket Boys‘  or seen the movie, then please allow me to recommend them both. My experience on the beach backs up the lesson from the book: if  you have young boys and want to channel their fascination with explosives, fire, weapons and space into a relatively positive and harmless direction (upwards!), then firing rockets must be just about the best activity. By the way, despite this gender-biased recommendation, Stephanie was the only bone-fide space scientist amongst us!
