Water of Life – a balancing act

For the next few nights I am here at Hale Pohaku Hotel & Resort for Stray Astronomers, exiled from the world, civilisation and my family.

Having the fortune of living in Hawaii, we are constantly reminded every day of the beauty that surrounds us. This planet we live on is a gift and it seems that we are only just starting to learn that there’s a delicate balance in the existence of this beauty around us – delicate, as once it is gone it will be very difficult to get back.

Paradoxically, one of the things that you become acutely aware of by living on an island is that precious commodity, water. You’d think that being surrounded by water  we would have no trouble with its supply for domestic and agricultural use…wrong. “But you’re in Hawaii,” I hear you say, “the tropics, it’s always raining there!”. Yes that’s true – we have lush rain forests, waterfalls and rainbows – but it seems that almost every year we go through a drought when the scarcity if water for domestic use becomes a serious issue for many on the island. (Part of the reason for that is that many on the island depend on rain water for their domestic water)

Maybe it’s an island-thing?! I was born on another island, in the Mediterranean (aka ‘Middle-Earth’ for all you Hobbitses out there!), called Cyprus. Water shortages are a very real problem there as there is nowhere near the amount of rainfall in Cyprus as we enjoy here in Hawaii. There are times when neighbourhoods go without water for days, the local government cutting off supplies in order to regulate its use. And they’ve come up with other “innovative” methods. There are two types of water supply: clean domestic water, and partially cleaned water exclusively for use with agriculture (almost everybody in Cyprus has a their own little ‘farm’ in their back gardens, no matter how big or small). I’ve heard my dad say at the table, “They’re watering our potatoes with sewage water! How do they taste?”

Now, back to the point! At the Hale Pohaku Hotel & Resort for Stray Astronomers, the problem is more accute as the Resort is built at the 9,000 ft level on the slopes of Mauna Kea, and all water needs to brought up here by tanker. However, a very unique system for preserving water has developed. It has been around for as long as I have been coming here (gosh, that’s almost 20 years now!!) and it prevents you from wasting too much water in the shower. You’ve been awake for 18 of the last 24 hours, twelve of which you’ve spent at the summit. You only managed to get 4 hours sleep and you fall grogilly out of bed needing a shower before you start the next 18 hours. You get the mixer taps balanced just right and the water is perfect. You jump in and you’re really comfortable and you start to relax and your thoughts unwind from the previous night’s work at the telescope. Just as you get to the point when you think you finally understand what’s going on “up there” your back and shoulderes are scalded by extremely hot water coming out of the shower. From contemplating the universe in a zen-like state to 3rd-degree burns in a fraction of a second. You struggle to regain the balance but there’s no chance of getting back to that nice place. Whatever is in there regulating the mix of water has gone non-linear, chaotic. Add a touch of cold water and freezing water tries to frostbite your toes (and other bits!). Too much, go the other way! Ow, ow, hot, hot!

Soon enough you give up and get out. The shower has won and the water of life is preserved.

Mira’s birthday robot

I was rudely woken up this morning by an over-excitable young girl who has just this day started her 11th year of life. Jumping up and down on bed at 7am when I’m trying to recover from finishing a telecon with colleagues in the UK at 2am… grump!

And now that Operation ‘Get Grumpy Dad out of Bed’ is ‘Mission Accomplished’, what should we do?

Time for presents!

And what did we get?

A robot!?

And the robot itself is really cool! Introducing the Lego Mindstorms NXT :

This is the first one that Mira put together. Loaded the software onto the computer and made a simple program which sent the robot in a perfect square pattern. We’re going to have fun with this… more posts to follow on this I predict.

First post

I’ve been contemplating for a while about whether I should join the blogosphere or not, and today I thought I would just take the plunge. What have I got to lose?

What am I going to blog about? Well, that depends on how I feel at the time and what I’m recently inspired by. So I’m hoping that there’ll be a variety of things, things which interest me and maybe some of you. In the main, it’ll probably be about a photograph I’ve just taken or done something with. We’ll have to wait and see…

…let the adventures begin!
