Distance since last post: 75km
Weather: Cloudy, rainy.
Forecast: Bad for the next 3-days. Looks like I'll have to be careful!
Notes: Crashed into a lamppost while I was trying to mount my bike. No damage. Phew!

View towards Remagen (two bridge towsers can be seen at base of hill) in terrible weather.

No sun, no energy although somehow I'm managing to squeeze enough out of the clouds to charge the phone which is pretty amazing. Luckily I have enough juice on the UMPC battery and the Li-Ion battery to give me about 4 hours of computing. If I spot any sun at all over the next 3 days I'll have to stop and sap up as much as I can. Its going to be very tight. Will I have enough left for the final report in Duesseldorf?

Right now I'm in Bonn and at home with my wife. I'm only using battery power and won't be charging anything so there's no change to the plan. Apart from a long bath and a good sleep tonight ready for the last two legs on Saturday and Sunday.

When I did my first tests and calculations about the use of solar power to drive a PC I was quite amazed at the inefficiency of the process and today's 'laboratory conditions' test proves just how much room for improvement there is. It's thanks to devices like UMPCs that this is project is at all possible because I really doubt it would have worked with even a 'power saving' notebook PC.

Today I stayed at the campsite and put the Solar panel and Li-Ion battery through a 3 hours test. Its was a cloudless day with a very thin haze, 22 degrees centigrade and for reference I'm located at about 50 degrees north and 7 degrees east. The date is the 30th of August which is heading towards Autumn here in Germany. The test was done from 11:00 - 14:00 and I took the empty Li-Ion battery and charged it with the solar panel for 3 hours.

I estimate that about 1.2KW of energy hit my 7000 cm2 panel with about 660W falling on the Solar cells (3500 cm2). After conversion to electricity it created about 50w/hr of energy. Of that, about 40W was taken by the Li-Ion battery because it only uses a fixed current and voltage. It won't adapt to the power available. Due to input voltage conversions and charging losses, this left me with an estimated 30W of energy and after taking this through yet another set of voltage conversions and charging process, left me with a rather poor 18W of power. Of course this is enough for a few hours of work but isn't it incredible that so much power is wasted (or rather passed back as heat!)

I spent the rest of the afternoon trying to work out how this process could be improved and I've come up with a list of ideas that could help. I'll talk though them in the next post but right now I need to put some more cream on the back of my legs because through all the concentration I forgot about the sun and I've burned the bit right behind the knee. That's going to be really enjoyable tomorrow when I make the 70km dash to Bonn.

Here's a diagram I created quickly on the Q1b. Hopefuly it makes things a bit clearer. How would you improve the architechture?

This part of the Rhein, from Bingen, all the way up to Bonn, is really wonderful. And the campsites just keep getting better!

I'm still not 100% sure how much energy I managed to capture today but it looks like around 30W which should give me enough time to post without too much worry.

I stopped at about 10:45 and set up my solar collection point, ate my breakfast and waited. And waited. And got a bit bored! I managed to hold out until 1400 and then went for it. Nearly all the way up to Koblenz. Total distance for the day was about 61km which is really good and way ahead of schedule. I can now plan a rest day. Or rather another solar collection day!

I'm going to finish this entry now and make sure its posted before the battery runs out although right now its looking good.

Distance since lost post: 15km
Weather: Clouds thinning
Notes: I don't have much faith in the lead-acid battery. The Li-Ion battery seems to be charging much more reliably.

 Another day completed and I feel like I'm getting into a better rhythm. Checking emails and RSS on the mobile phone and creating rich journal updates with the Q1b. I only wish I had a  mind recorder because I'm thinking of some great ideas while I cycle but forgetting them when I get to a point where I could write them down!

The bike, which I've decided to call Berta (the Blue Bakers Bike) is performing fantastically well. I was a bit worried about having no gears but the fixed gear ratio is perfect for around 22km/h which, with 65KG of pack on a 25KG bike is just perfect. The thick tyres help to soak up bumps and now that I've pumped up the pressure a bit more, seem to roll without too much resistance. I even clocked 34kn/h on a straight today . Wohoo! Berta is Berta

Tomorrow morning I will cross the Rhein on a ferry over to Bingen, a lovely town that I've visited before, and then continue up the left side of the Rhein. The hills meet the rive here and so there could be an issue with mid-afternoon sun dipping behind the hills. If that's a problem I'll switch sides again but I can see from my map that the route on the other side takes me up into the hills. Not good!

Time for some sleep now. I had yet another good meal and feel like I've capped a good day!

Distance since last post: 40km
Weather: Mixed, cloudy. Hazy. Warm 20-22 degrees
Notes: Feeling really good. No aches. Pushing harder today. Cant stop eating sultanas! The hills on each side of the Rhein are getting bigger!

Winter is coming...If you take notice of the geese that is. I saw a flock flying south (following the River perhaps) this morning and wondered if they knew something that I didn't. Its was lovely and warm yesterday and its pretty much the same today. Is there some nasty weather around the corner or did they get an SMS from some Geese mates in Africa telling them to come early?

Although its been warm its been very cloudy today. Much cloudier than yesterday and yet I still managed to get some charge into the Li-Ion battery and (I think) something into the lead-acid battery. Despite that though I'm using my spare battery and thinking carefully how to use the UMPC more efficiently. Daytime use (like now!) is not the best as the backlight needs to be turned right up. That's draining an extra 2 watts compared to evening use when I can drop the backlight to minimum.

I felt very strong this morning and powered the 85KG bike/baggage combo through to Mainz in much less time than I had planned. It was really enjoyable. While the clouds where thick I kept on cycling and ended up in Eltville where the was a lovely Rhein terrace restaurant serving Spargel Suppe (Asparagus Soup.) I stayed for an hour while the solar panel and bike rested by a tree and then layed myself down on a bench for an after-lunch nap. After buying, writing and sending a few postcards I carried on the journey. The Rhein-side path was pretty bumpy and at every chance I tried to find another route but this was really the only sensible offering, the other being a trek up to the hills! Then, after about ten minutes I heard a crash behind me and stopped as quickly as I could. I looked back to see the battery packs and cables strewn across the path along with the shattered container. Shit! I gathered it all together, repacked it and then checked everything out.I think I've been lucky. Everything seems to be working still so I think it was just a warning from above to tell me not to take afternoon naps!  

Only about 20km to go until the campsite and having looked closely at my plan, it appears that I'm ahead in terms of distance but behind in terms of energy capture. I need to take longer breaks. But no afternoon naps!!

Location: Oppenheim
Distance since last post: 68Km
Weather: Hot with 50% cloud cover
Forecast: Heavier cloud tomorrow. Clearing toward Thursday.
Notes: Problem with the Lead-acid battery today. It didn't seem to charge. Will concentrate on loading the Li-Ion battery tomorrow.

Due to the cloudy weather I decided to cycle all the way through to the campsite in one stage today. I chose a route slightly away from the Rhein which had the advantage of being more direct but the disadvantage of being inland and therefore higher. Hills are not something I enjoy on the 25KG Kronan bike! The route was nice though and it took me through endless lines of grape vines (and loud, gun-like bird scarers going off every ten seconds all over the valley) that are almost ready for harvesting for wine. Every town and village seems to be advertising their Winzer (Wine) Fest!

The mobile phone I have is doing very well as my email notifier and as (filtered) emails come in I get a little beep telling me to stop and take a look. Its nice to be able to say I'm in the middle of a Vineyard' at the end of each reply! But that's about it for the mobile phone. Trying to do anything Web-like is slow and terribly inefficient. Firing up the Q1b UMPC every now and then keeps proving how perfect they are for Internet activities. There's no way I would be able to write so quickly, create the maps, review and edit the images and communicate via IM through all the protocols possible without it.

I'm camped right next to a beach on the Rhein (that's the Rhein behind me there!) and can hear the waves lapping against the shore. Every 10 or 15 minutes a huge river boat can be heard either coming down from Rotterdam or heading up from the south somewhere. Fuel, sand, containers and even the occasional passenger boat. The Rhein is a business river. I wonder how long it remains efficient compared to trains, trucks and air transport.

I haven't planned tomorrow in detail but it won't be as long a journey as today. The Lead-Acid battery I have (2.2KG worth of old technology) didn't charge well and so I'll concentrate on loading-up the Li-Ion battery. One bit of good news though is that the mobile phone charges from the solar panel even in bright daylight. If all else fails I'll have to email the blogs via T9 but I hope that doesn't happen. I still have a fully charged spare battery for the Q1b so I'm not in trouble yet!

Location: Here (just south of Ludwigshaven)
Distance since last post: 27.1km
Weather: Warm 25 degrees C. Some cloud cover.
Notes: Counted 33 mosquito bites from last night. My back got eaten. There must have been one in the tent. He's full up now!

When I arrived at the campsite this evening, the tent area was empty. About 30 minutes later someone turned up on a recumbent and, as you do, we started chatting. My 25KG bike is usually a good conversation starter!

Manfred is 63 and from Constance, where the Rhein river starts. He had just finished a 120km run and was on that last leg of a tour he started at the beginning of August. He had already been down the Rhein to Holland and was on his way back! We went for some food together and he was telling me about his career in computing and I tried to explain a little about what I was doing. Of course we had lots to talk about but I held back on saying too much about UMPCs. On the way back he was telling me how pocket PCs don't have the right OS, how the communicator has the same problem and how he wanted a small windows XP (not Vista - he still has some DOS programs that need to run) machine. When I showed him the Q1b back at the tent he was amazed and when I connected to the Internet on the spot he couldn't believe it. I passed my card over and smiled saying that I hadn't expected to be promoting UMPCs face-to-face on this tour!

I'm settled in the tent now and I can hear Manfred snoring (yes Manfred, if you read this, let me tell you that you snore!) The Q1b has about 20 min's of battery left and I'm going to switch to the external one soon.

Tomorrow I will have to see how the weather goes. If its as good as today I'll take a nice long lunch break and load up as much as I can because the forecast for Tuesday isn't as good.

Location: Speyer.
Distance since last post. Approx 30km
Temp. 25 C
Weather. Blue skies!

Awake at 0730 after a really good sleep and a horrible dream that when I got out of my tent I was in an empty campsite...with no bike. Packing up camp took a bit longer then expected mainly due to the dampness of everything and the fact that I usually get up at 0900 and not 0730. I also had to deal with about 10 mosquito bites. Damn they are annoying. On the road at about 0915.

At 10:45 this morning I pulled off the path and set up the solar panel for the first time. I haven't actually tested it with the frame yet because I only finished building the frame a day before the tour but with a few strips of velcro it folds back on itself nicely and stays well in place. Its a pain to be getting things out of the panniers all the time though.

There are literally hundreds of bikes out today. The route is well ridden and of course, its Sunday. Everyone seems happy and friendly. I chatted to a couple of bikers at a train crossing and then, 30 minutes later they passed me in the opposite direction waving and wishing me a happy journey. That really helps make it more enjoyable.

I'm riding at about 20km/h on the bike which is a steady, but certainly not fast pace. Taking into account stops I think I must average about 15km/h while riding which means 3-3.5hours riding per day. I think that will fit nicely into the plan of a morning and late afternoon ride.

The Q1b is working well here on a table in a biergarten. I was worried about the screen not being bright enough but in there shade there's no problem.

Now its time to catch up on emails, RSS feeds. See you at the next campsite.

I made it down to Karlsruhe in Germany after a quite stressful train journey with the bike and all the kit and after a short journey that turned out to be a 2.5hours trek to the campsite. I just managed to get the tent up before it got dark and I had to dive straight into the tent though because there are thousands of hungry mosquitos here.

After spending an hour trying to organise my kit inside my one-man tent (I gave up) I finally settled down with the local radio playing on the mobile phone and the Q1b lit by my USB led lamp. How nice!

The campsite here is terrible. It's right next to a factory and full of drunk people. In front of me is someone trying to play the bongos and to the right of me is a family having an argument. Mmmm. I hope it gets better than this!

Tomorrow will be the first test of the Solar kit. Will it work? Will I be sitting in my tent tomorrow evening surfing the net and writing journal entries or will I be playing cards?

Planning a busman's holiday around the weather isn't that easy. Camp set-up and break down, cycling between locations, working, keeping an eye on the weather, finding suitable places to work and charging power sources all need to be thought about. The key to success here (in our wonderfully changeable weather system) is to be flexible between 10:00 and 16:00 when there's a possibility to get something out of the sun. Outside these hours there isn't enough power in the sunlight to make it worth any effort or planning.

The original plan was to cycle during the day with the solar panel across the back of the bike however, a 25W panel is too big to lay in a useful, efficient position across the back of the bike so either I suffer with 50% energy loss or I stop when the sun shines. Having thought about it for about 2 seconds I think the latter idea is rather good and in fact, the objective of the tour is not to cycle as far as possible, its to test and learn about how UMPCs can be used and powered in mobile situations.

A rough dry-day plan could go like this.

• 0730-0830 wake up. Check email/RSS, Cuppa, Breakfast and pack up.
• 0845-1100 on the road for a concentrated 40km ride. Panel 50% deployed on bike but not expecting any usable power at this time of day.
• 1100-1600 Weather watch! If its sunny then stop and charge! Work, play, read, eat during this time. If not sunny try to get to campsite before midday in order to deploy trickle charge solution. Best charging period is 1200-1400 here.
• 1700-1900 If not already at campsite, set up tent. Find food. Shower. Food. Relax. Connect mobile phone and AA batteries for top-up from lead-acid battery.
• 1900-2100 Work (max 1.5 hours)
• 2100-2130 Prep for morning.
• 2200-2300 To bed with RSS, emails or book. Pray for sun! Earplugs in (camping by the Rhein is always noisy) and sleep...

Next job is to get the Google map started. I'm using RoboGeo to generate a live route map (here's one I prepared earlier!) with images but I'd like to merge Google 'My Map'  KML data with it so that I can build more than just a track map. If anyone has any ideas about this, please let me know.

Update: I worked it out. You can create the My Map in Google Maps by doing the usual drag a nd drop, draw etc etc. Then export the KML. Uload the KML to your web server and add the following two red lines into your RoboGeo 'map.htm' file after the 'var map' line. Obviously you need to adjust the URL to point to the KML file you uploaded.

var map = new GMap2(document.getElementById("map"));
var geoXml = new GGeoXml("http://www.solar-
umpc.com/images/moblog-30-4-07/SolarUMPCTour.kml");
map.addOverlay(geoXml);

Once you've done that, upload the RoboGeo dir to your server and link to the map.htm file.

Here's one I've just made with a previous RoboGeo route and photos and if you zoom out you'll see the start and endpoint for the tour and the current location of my bike. The great thing about it is that as you update your 'My Map' the created map changes too as it pulls in all the data from the Google servers. Wonderful!

I'm now off to do a bit of shopping. Packet soup, sultanas and muesli bars. Yum yum! create some maps!

And that is about as good as its going to get I think. Time is running out fast and a good weather window is approaching. 'Only' 20-30% chance of rain. 6 hours of sun per day. 28th, 29th and 30th don't look too fantastic but I'm afraid I'm going to have to take the risk. The Solar UMPC Tour is under starters orders!

After this blog post I will be emailing my PR contact at VIA Technologies and awaiting confirmation. I want to start on Sunday 26th of August and go through to 3rd Sept where I will finish on the Rheinufer (Rhein River promenade) in Duesseldorf and drink a huge Krystalweizen beer!

My decision was made only hours ago and I've just realised there's a lot to do in 3 days. Posting frequency will be picking up here now so stay tuned!

Frank, another UMPC blogger found this...

He blogged about it here and called it a 'European solution.' He might be right because this year has been a terrible summer. My BBQ rate is down to once a week when it should be at least three times per week! A wind solution would need to be a lot bigger than this one though. According to the designers web page it takes 12 hours of wind to store enough power to charge a mobile phone. Mobile phones run on batteries of about 3 watt/hour. I'd get about 20 minutes of UMPC time per day with this version.

Frank. It might be easier for me to Fly over to Florida. You provide the tour Oranges OK?

I know that weather is supposed to be chaos but this is just silly. The most settled weather we've had this year was back in April and since then its been a real mess. It doesn't look like it wants to change much either. The whole of central Europe is stuck in a mess of clouds that does not want to move and bizarrely, Helsinki, the place I've just come back from in northern (and generally colder) Europe is expecting a ton of sun!

Getting everything re-organised in another country is not something I really want to do to be honest. There's a lot of cost and time issues that would make the project too much trouble for me and my sponsor, VIA Technologies so once again, I'm going to wait. The 9-day forecast takes me up to 18th August. After that point I have about 5 more weeks left in the summer before the sun gets too weak.

 I took a long lunch break today for a solar UMPC picnic!

The Q1b was really difficult to see in the sunlight (as are all UMPCs) there but after a while, my eyes actually adjusted a bit and it was useable. The only problem is that you have to wind up the backlight which kills the battery life. I will have to be working in the shade on the tour.

Speaking of which, I'm still planning it. I mentioned before that the weather has been bad but its starting to look better now. I have to wait for my daughters 1st day of school on the 7th August and then I'm free to choose when to go.

One other thng to mention...A cool Solar Lamp that Kornel, one of the UMPCPortal team, sent me from his holiday. It works! Thanks Kornel. I'll be taking it with me.
