There hasn't been many photo opportunities over the last few months, so I've put up some random photos I've taken on my phone just to brighten up the writing!
Scrabble problems
I don't quite know where the time has gone since coming back from Nepal. I've been finishing my turbine selection section of my work, and now have an idea of where I'm going mechanically. I've even submitted a paper to the World Renewable Energy Conference 2011 in Sweden about my selection method and outcomes, as it's not the usual way to select a turbine. Now, I'm modelling the turbine in a bit more detail and looking to see how I can experiment with it. Which comes to one of the frustrations I've reached. I thought I'd be doing a lot more practical experiments, but I suppose you have to do the theory first and come up with some ideas before you can test them. It's not the sitting in labs and fiddling with switches and buttons that I thought it would be. Not yet anyway.
Swappable heads on top of my computer
In PhD-land I've also been reading into the electrical side of things - how grids are made, how generators are connected together, control systems for these and so on. It's meant reaching into the deepest depths of my memory and trying to retrieve my old electrotechnology lectures. This has actually been very interesting, realising why things are done as they are in this world: the choice of 50Hz as a standard frequency in Europe, reading the history of the electrical current wars between direct (constant) advocated by Thomas Edison and alternating with Nikola Tesla and George Westinghouse beating its drum. (To read about the current wars see here). I've also spent some time looking at the National Grid here in the UK, as this can provide ideas on how to operate a remote electrical grid. There's an interesting bit on the BBC about how the National Grid copes (or doesn't as the case may be) with the peak in demand at the end of Eastenders here.

I've been doing a lot outside uni as well. I've been asked to be Deputy Stage Manager in Horfield Theatre Company's latest production, Bad Girls - the musical. I think it's going to be fun!
I went to the Ashden Awards in London on the 1st July. These are awards for sustainable energy solutions. This year there were some interesting and a wide variety of finalists. I thought it was great to see Okehampton College and St Columb Minor School, as they were spreading the knowledge amongst children, which worked its way back to their homes. The Isle of Eigg in Scotland had formed a remote grid using hydro, wind, solar and diesel which was great.
I spent a long time talking to the MD of Eigg Electric about the operation of their grid. It is a fantastic example of how renewable energy sources can be used to link up and supply communities. Although it would be great to implement similar schemes across the UK, Eigg has several advantages. They are a solid community, with everyone working to the same goal - partly due to their island location. On the mainland this sense of community doesn't really exist as much. They also accept limitations on their power - a maximum of 5kW per household. I think that most consumers wouldn't like the power being cut whilst using their electric shower if someone switched on the kettle. And also the cost of it was very high. Pico and Micro hydro is normally quoted at about $1000 per kW generation (£700/kW). On Eigg, however, the cost was £5440 per kW - and that is including the two 80kW standby diesel generators. I just don't think it's commercially viable still. Soon, hopefully, the price of the technology will reduce and maybe this shining example will be replicated all over the country and the world.
Having a lie down on Bridge Valley Road in the Midnight Walk
Last year Lynne Richards, a most wonderful woman who I had the pleasure of knowing, sadly passed away. St Peter's Hospice in Bristol supported Lynne and her family. St Peter's was organising a Midnight Walk, where women would walk 10 miles around Bristol. It seemed very appropriate to us all, as it would be on the same day that Lynne died last year, so a team of ladies from church was going to attempt it. Not to be out done, a group of men, including me, decided we would support them all by marshalling on the route. I was posted on the closed Bridge Valley Road, and enjoyed watching all the women puffing and panting coming up the road. When we returned to the finish, I regretted my previous smugness as I was tasked in cutting the tags from everyone's sweaty ankle. Karma.

It's strange how things happen, this morning I woke up with an idea. I think it may be the basis of the idea, the idea that is going to push my research into the unknown, which is where I should be heading. It's been exciting trying to write it down to understand how I'm going to accomplish it. It's going to take a long time to develop it properly, but I finally have an idea. Woo.
I'm off to Greece for a couple of weeks now, one of my close friends is getting married. I'm looking forward to the break, sunshine, and a chance to sleep.
For now
