+=== Solar ===
+We used solar panels on the river to cover our (small) power requirements.
+We used a small solar panel, 25 x 35 cm (wattage unknown!) to recharge our batteries: phones, GoPro camera, SLR, AA batteries, etc. We found that the [[http://www.inca.net.au/chargers.html |Inca charger]] worked really well and enabled us to charge all these things easily.
+We also used small rechargeable lights / USB chargers (link to follow) which were great in the evening as the light ws diffuse and they could also be used to "shock-charge" a USB powered device to bring it back to life.
+Foe the Danube we have been looking at a larger solar system. We need to have a working anchor light each night. So battery capacity of around 10 hours with 10-20 watts (0.8-1.6 Ampere), i.e. 8 - 16 Ah.
+Offer of Lithium-Ion batteries, 9 Ah capacity, looks good, but there are few solar charging modules available on the market. The only one seems to be:

+charging systems for lead acid batteries are more easily found, even from [[http://www.conrad.at/ce/de/overview/0509051/Solar-Laderegler | Conrad]], prices around 15-50 Euros.
+In the end the solar system used on the Danube and in Belgium avoided the batteries as they held almost no charge - the problem of trying to re-use old tech. Some ideas on how to reinvigorate old lead-scid batteries would be good.
+We also purchased but never used (no battery) an [[ http://www.igo.com/| iGo ]] (will attempt to find exact details) which should be able to charge all sorts of laptops, etc. More details as they come to light.

-Travel is expected to be between 20 and 40 kilometers per day, based upon experiences of 2 similar projects. Water currents will be important. The can be found [[here]http://riversmart.net.au/Flowtracker.htm], and it seems that if we take the river to be 150m wide and 4 meters deep, the flow at the SA border is around 0.5 kmh, compared to 4-6 on the Danube.
