Did anyone else spot the super soaker water squirt gun strapped to the trike? What's it for?
I'm going to go with stray dogs, the bane of a touring cyclist's existence.
Bingo! Anne-Sophie had many bad experiences with dogs when she was unicycling across South America so she wanted us to be prepared, and read on a cycling forum that a squirt gun with vinegar works well to put a chasing dog in it's place. Seemed that the backwards facing rider would be in the perfect spot to be on dog defense.

However, the one time it's been used AnSo was reaching back for the gun in a panic and pulled the trigger continuously while trying to unleash it, completely soaking me and our navigation tablet. I was laughing in hysterics the rest of the day. When she finally got it free and pointed the right way, the dog was like hmm, water so what, and was already slowing down anyways.

So far it's just been Serbia with lots of stray dogs on the streets, but most of them either watched us roll by with idle curiosity or stop running after a small half-hearted chase. It's not really been an issue though now the squirt gun is part of our rig fixture and will stay for the trip.

5 border crossings so far and no border guards have asked about it either, I thought we'd at least get some joking from them.

Justin, at Recumbent Cycle Con which is put on my Recumbent and Tandem Magazine, we has a presentation by Azub where we saw some pretty terrible road conditions in some of the area's you are going to be traveling in. Are the Solar Panels working out as well as you thought they would?
Electrically for sure. When the angles are right (ie we are heading in a northerly our southerly direction and can tilt the panels to fully face the sun) we'll see 400-450 watts often enough.

With clouds it's really interesting and varied. There are times when the sky is covered in clouds without a blue patch in sight and yet we're getting like 300 watts on the panels, with tons of diffuse sunlight still making it through. Other cloud filled skies which appear to look just the same only allow 80-100 watts of power in. However, when you look straight up you can normally feel the difference on your face between these two cloud situations.

When the clouds are darker grey, then it drops down to 20-30 watts, and when we have rain clouds bearing down (which has happened a LOT the past 4 days) the solar drops to near zero, and then we seek refuge under the panel for rain protection.

However the best condition is not a clear blue sky but a cloudy sky which happens to have an opening for the sun to shine through. Then you end up with both the direct solar light from the sun, PLUS all the diffuse light from the adjacent clouds. At one stage after a rainy morning in Italy we saw over 590 watts from our 550W peak panel.

It was like magic, literally the silver linings of the clouds doing this. Sadly the circumstances for this are normally short lived.

The converse situation is also true, if we have a clear blue sky with just a single cloud in front of the sun, then we end up with like 30-40 watts, much less than if the entire sky was cloudy. Luckily these situations don't last long.

Structurally the roof has been holding up decently well given the total last minute and untested nature of the foam+fiberglass construction. When we assembled it in France I was short one M4 nyloc nut so only put 1 rather than 2 screws on one of the front supports. That came back to bite me since the shock on the front of the roof caused this one screw and washer to puncture through the thin fiberglass wall so it's not really holding it securely, and then the roof could bounce and it the support structure here which has caused the fiberglass rib to crack a bit and no longer holds the edge of the panel totally straight.

Damaged Roof Support.jpg

The other 3 attachment points are all fine. My plan was to reinforce this damaged mount with some sheet metal but now that we have the large 2.8" front tires, the shock on the roof even with bumpy roads is so much less that it's not really getting any worse.

Also, where the two halves of the roof join in the middle there is now a noticeable sag at the joint so it's not totally flat across the top. It's not a bit detail but I'm likely going to use a strut and string to do some triangulation to pull the mid section upwards a bit.
SagInRoof.jpg
SagInRoof.jpg (151.24 KiB) Viewed 1160 times
And finally, the roof tilting mechanism initially had two hand turn knobs for locking or unlocking the rolling wheels, but these were M5 threads in an aluminum plate and I forgot to grease them before the trip. At some point in Croatia the rear adjustment became seized as the aluminum/stainless galled, and then when I unscrewed it all the threads shore off.
GalledAluminumThreads.jpg

So we're now using tools to loosen/tighten the roof for pivoting and have to stop and dismount for that which is annoying compared to being able to adjust it while riding.
Are there improvements you would make to the setup?
Suspension! More USB charge ports, easier to access camera holders, and retractable side curtains off the roof that we could pull down for better water protection during heavy downpours. And a better job of having organized stowage containers for all the various odds and ends so that we can be faster and more efficient about packing/unpacking or getting supplies (like sunscreen, duct tape, gronala bar, a USB charging cable etc). We've been making additions and modifications the last few days and will be doing more today as we wait in Sofia for a care package from Grin to arrive.

I am hoping, when you have time, that you will do a detailed presentation of the solar/regen technical details, suppliers, performance, wiring, etc. Basically, I am looking for guidance on the most efficient solar set up for a bike. In all the Sun Trip posts and videos I have gone over, I haven't found this yet.

Thanks and thanks for all of your wonderful posting for us armchairs.

There are a bunch of us old-timers, I'm sure, lurking along in this forum. It's hard to believe it's been 10 years since Justin stopped by on his cross-Canada trek. With the engineering, these updates, and following along with the tracker data on Google Earth - this is a great adventure to ride along with vicariously :D. Wishing Justin and An-So safe passage and a timely return to Canada.

That was the first thing I noticed when I saw the picture.
Luckily you chose an obvious toy gun, unlike what other people are known to handle.

Other than the missing bolt, have you had any other issues with the foam core/fiberglass panel racking? I did that last year, except I used a flax fiber woven fabric instead of fiberglass. A ridiculous amount of labor hours, but they ended up being very light and strong. The only issue I had is that they earned the nickname 'dancing solar panels' because of the rickety aluminum poles I used below.

They appear to be shopping for floor tile in Svilengrad. :) Or maybe a toothache. There appears to be a dentist across the street.

I did the same thing as you, and was stunned by the derelict building that they're apparently spending the night in. Then I realized that the latest Google images are from 2012, and the Guest House wasn't renovated until 2014. *whew*. :-)

I dunno. I think they've been doing a lot of roadside camping given some of the locations where the map shows them stopped. And there's an empty lot across the street as well. It will be interesting to know more once they are finished with the trip and their honeymoon.

Phil, thanks for dropping in and so great to hear from you again, and yeah it is crazy to think that 10 years has gone by. And at the same time how both so much and so little has changed.

While there are lots of pretty derelicty buildings in this rather curious Bulgarian border town, tonight we're almost staying in the Radisson!
RadiInn.jpg
It's funny, we wound up here because of an ongoing game of cat and mouse with a Fedex care package we've been trying to receive. It ended up being a day late in Sofia and we didn't want to wait any longer so had them redirect it to the first hotel we could find in the south/easternmost part of Bulgaria. Online it was called the "Radi Inn" but it wasn't till I saw the sign that I got it :-)

Anyways, for those who've been following the race, we've been loosing ground the last week and are about 3 days behind schedule for where we wanted to be assuming a ~200km/day target.

That's partly from frequent worthwhile distractions, partly from the 4 day "Raintrip of 2018" that we and most other riders got caught up in last week, and partly from a full 24 hour stopover in Sofia waiting for this fedex thing. That means that in order to actually make it to our flight out of Tehran in 2.5 weeks at this stage we really need to book it!

Today was finally a perfect day that played out how I imagined most of the trip would be. We clocked 220km averaging 30kph while consuming 12.8Wh/km, with sun almost the entire day, arriving before sunset and not completely exhausted. I've got the full data log available for people to look at here (Including named sections where we stop for breakfast, fixing flat tire, gas station pit stop, and getting pulled over by Bulgarian police..)
http://www.ebikes.ca/tools/trip-analyze ... rip=QL43AM
(I recommend switching the horiztonal axis from "distance" to "time" after it loads)

We spent most of the day on a major freeway with super wide shoulders and no trees lining the side of the road so there was minimal shade to deal with, and the result is a solar output graph that has very few dips in it. It peaked around 390 watts mid-day, and gave just under 3kWhr of solar energy for the day.
SolarOutputGraph.jpg

Our preferred method or riding is to use the CA3 to set a speed limit and we use that as a cruising speed, and then the speed limit is adjusted up or down if we want to increase or decrease our consumption. We started the day with it set to 30 kph, but after a breakfast stop and due to tailwind the battery was getting nearly fully charged and so we increased our speed to 32 kph for the bulk of the time when the sun was mostly overhead.
SvilengradTripGraph.jpg
SvilengradTripGraph.jpg (163.56 KiB) Viewed 975 times
Later in the evening, as the sun was further down and we weren't totally sure if it might tuck behind evening clouds or not we changed to a constant power rather than constant speed mode on the CA3. That way we could be sure to properly meter the power out of the battery pack to ensure that no matter what we'd be able to make the full 220km distance. As we approached Svilengrad seeing that we'd make it with plenty to spare we started being less thrifty on the motor power again.

Started the day with the battery at 36.0V, ended the day with the pack at 36.2V after eeking out some late evening sun by the hotel.

I mentioned police. Bulgaria has some excellent roads and some terrible roads, and yesterday while following a recommended bike route we were on atrociously bumpy road with no shoulder and cars wizzing by as though they were on a freeway. So we switched to all freeway riding today and it was just perfect for solar biking. Totally smooth, wide shoulder, minimal shading, minimal elevation changes etc. There was a sign that said no tractors but nothing saying no bicycles and we had at least 3 police cars pass us without any issues.

Then towards the end of the day we had the flashing blue, apparently bicycles aren't OK here after all and we were very politely escorted off the freeway. And then the police car did like almost all the other cars that passed us, they took out their cell phones and started filming us as we rode away :-)
BulgarianWhiteAndBlue.jpg
I mentioned a flat tire too. Our large 30PSI knobby front wheels seem to be holding up decently well, but they certainly don't have the same puncture resistance of the worn out Marathon Plus's. In this case it was a small curled steel shaving (looks like it was hot off a lathe) which worked into the tire and made the leak.
FlatTireNumber4.jpg
I imagine this will be a semi regular occurrence and we'll need to budget time for it in our contingency planning.

Anyways, we're now in this not quite radisson hotel REALLY praying that the fedex package arrives in the morning so that we can set off to Turkey next!

Yep. You get all that benefit from the cloud lensing, plus the panels are cool (=higher voltage) plus they are clean from the recent rain. We've seen productions 20% higher than the STP ratings of the panels in conditions like that here - at least until the panels warmed up again.

Here's to a fun story and a good prayer. Said a quick prayer for your package to arrive as well. Don't know if it will help, but a little help never hurt in a time like this.

Well guys, here I was expecting to spend a day in a hotel lobby answering a bunch more questions and filling you in on all the many little side adventures we've had so far while impatiently waiting for a Fedex delivery that I was all but giving up on. And then, what a surprise, even before I could get my next post finished!

Thanks e-beach, the prayers were answered. We're now going to try and do 180km to Tekirdag before the end of the day and see what ferry schedules are like for tomorrow to get ourselves back on schedule (and to get ahead of the french Viguer brothers who are hot on our tail). Batteries have been sitting fully charged for a couple hours, time to rip!

Thanks a lot for the data on your "perfect day". Highly appreciated.

I hope that someday after the trip there will be data available for every day and every vehicle involved. That would be great.

Can you show data from a day with rainy or overcast weather, too if you find some time to do so?

I wonder about the rather high consumption of around 11.2Wh/km at "only" 30,6km/h average speed in perfectly flat terrain.

I expected more efficiency especially on a tandem trike. Maybe it's the very bad rolling resistance of three knobby tires or significant air resistance or did you experience heavy headwinds?

Good trip und all the luck you need!

I expect that when you consider the amount of stuff they are packing and a solar roof panel that isn't always attacking the headwind on a "knife edge" and that has a bit of a sag, that the trike isn't particularly aerodynamic.

What an unsettling place to end the day. The final tracking data for today leaves them here (not much around):

Image

This section of road (Muratlı Çevre Yolu) is very much a new work in progress - not sure how old this satellite image is, but if there's still no bridge there, it could be hard on the trike. Hoping there's no reason to be worried. :(

Well! If nothing else, this had me scratching my head a bit and ultimately updating to the latest version of Google Earth Pro (thanks, solarEbike - a picture is worth a thousand words). Nice though the new road looks, it's an odd place for the tracking to stop for the day. :(

(thanks, solarEbike - a picture is worth a thousand words)
Perhaps a few words would have been helpful here.

The buttons indicated below turn Historical Imagery on and off. Try fiddling with those settings if you're not seeing the imagery you expect to see. In particular, try turning this feature on and off. If you're still not seeing the new image then it's likely that it's so new that Google is still in the process of rolling these out to all of their servers. It can take a while for everyone everywhere to see the newer images when they roll out an imagery update. I can't see the newest image when I have the Historical Imagery window open but if I check back in a few days or few weeks, it will be there. The version of Google Earth used shouldn't have any affect on the imagery you see unless perhaps you're using a really old version.

My guess is that this is not where they've stopped for the night since their last known speed was 24 kph and the last tracking point was at 7:30 PM local time and they've usually been stopping for the day closer to 9 PM. Their stated destination for tonight was Tekirdağ 30 km away so it seems feasible they made it there and the tracking data just isn't keeping up for some reason.

Maybe the Spot device has a low battery? JLE mentioned lack of USB ports and they just got 2 more in their last care package. The satellite network could be down but there appear to be updates past that last timestamp from others. This assumes that the Sat-View platform is correctly accounting for time zone differences. Or perhaps they've been abducted by aliens and will mysteriously re-appear many km from their last known location with no knowledge of how they got there. The most complicated explanation is usually the correct one, right?

UPDATE: So it looks like they camped by the side of the road in a field 4 km (10 minutes) down the road from this spot. Maybe they set up camp and noticed that the Spot device needed charging and plugged it in and it started broadcasting again? I plan to use an inReach device for my trip but I don't plan to broadcast the locations of such campsites until after I've left the location.

Thanks e-beach, the prayers were answered. We're now going to try and do 180km to Tekirdag before the end of the day and see what ferry schedules are like for tomorrow to get ourselves back on schedule (and to get ahead of the french Viguer brothers who are hot on our tail). Batteries have been sitting fully charged for a couple hours, time to rip!

Well, it looks like they must have caught a ferry because the appear to be in the middle of the Sea of Marmara right about now.

For the other folks on the road who check the tracker and aren't aware that Justin and An-So had planned a ferry ride (would this not render them disqualified, were they actually going the distance to Guangzhou?), it would give them pause to wonder what other special features this trike has. I mean, this *is* Justin after all :D.

On another note, the Viguiers are really bolting along.

One of the approved ferries, too. At first I thought it looked like they might be taking a bit of a shortcut by not riding all the way to the Bosporus and taking one of the short ferry rides to cross there but the official Sun Trip map has an advisory about avoiding Istanbul altogether due to traffic concerns.

I've added these additional map layers to my KMZ file if anyone wants to re-download (directions). It has lots of useful tidbits for the participants like good/bad border crossings, approved ferries, locations of helpful hosts along the way and no go zones. I've used some of this data to plan my own around the world trip. Thank you to the organizers for making this available.

The KMZ file also works on an iPhone if you get the Google Earth app. I assume there's an Android equivalent. No elevation profiles and it crashes a lot but kind of handy for checking the status while away from a computer. Here's a screenshot from my phone.
