I talked yesterday about my testing with the Viliv S10 and my 24w solar panel. Today I’ve implemented the solution as my desktop PC.

Previously (for the last 5 months) I had been using a Fujitsu U820 UMPC as my desktop. It was running Windows XP on a Intel Atom 1.6 CPU. The Viliv S10 is running Windows 7 Home Starter on the same Atom 1.6 CPU. Both solutions use a fast SSD. You can see that I have it set up to drive an external monitor, mouse and keyboard but I’m still using the screen on the S10 as an extended monitor. With the extended screen, Windows 7, quieter operation and a better USB solution (the USB bus on the U820 would often reset causing a keyboard and mouse lock-up) this is a better working solution than I had before.

I’ve just done an interview with the  HomeofSolarEnergy website which I guess will be posted soon. The best thing about it was that it got me unpacking my solar panel and thinking about a simple solar powered computing solution again.

Update: The Interview on Home Of Solar Energy is available here.

I mentioned the Viliv S10 in an article about solar-powered computers for 2010 and it turns out that it has the same 9.5v input as the Viliv X70 tablet. Having an input voltage below 12V is always an advantage and it’s even better when the X70 car adaptor works on the S10. I threw out the panel, connected it to the car adaptor and S10 and we’re away. I now have a 3G-capable, Windows 7 convertible netbook running directly from the sun.

I’d love to get out an do another Solar Computing Tour in 2010 but I’ll have to plan it carefully. Our new baby is due in March so maybe I can pull a long weekend together in late August but we’ll have to see how things go.

It doesn’t stop me thinking about solar computing though and in this post I’m going to compare a set of devices and some technologies that will be important for the job of Solar PC 2010.

Before I do that I want to highlight a few things that really haven’t changed much in the last 3 years. It’s a sad story of minimal progress.

• Solar panels – NOTHING has changed. They’re still expensive and inefficient.
• Battery Tech – NOTHING has change. They are still expensive and use the same technology as before.
• Operating system choice – Nothing has really changed. If you want to work efficiently you need to choose the same OS as you use on the desktop. Mobile operating systems have come a long way but there are still too many potential roadblocks for the average productivity user. Windows 7 is nice but compared to XP it’s less efficient which in my book, makes it the best choice for efficient and productive mobile computing.
• Screen technology. Outdoor users are still fighting the sun with LED backlights although this is a great step forward from the CCFL backlighting I used in 2007. Transflective screens are coming in 2010 though. See below.
• Weather – Ah, there’s something that hasn’t changed much either! Still, constant chaos. (Thank goodness!)
