Remember that the Voc is at a certain temperature and there will be a factor that it increases by for each degree centigrade below that temperature. Explained, with a worked example, at https://www.ecmweb.com/renewables/article/20896643/the-highs-and-lows-of-photovoltaic-system-calculations a fair way down the page. so you might need to consider what they will be doing on a really cold winters day.

The power shouldn't be a problem, the specifications for the smart version is a max power of 440w. Possibly of more concern is the maximum voltage that you will get out of your 4 panels in series, as noted in the manual. Perhaps two parallel pairs of series connected panels would be better. The images are from the smart solar manual. If yours is the non smart version, you can get the right manual to check from the Victron website.

This document, https://nabo.org.uk/files/members/trent_sg.pdf , from 2009 says: "BOOKING and MAKING PASSAGE Give 24 hours notice to the keepers before using the tidal locks. " So it seems that the need to book existed long before CRT, and so the reason given by nbw is nonsense. (the article has been edited to remove the misleading photo of a completely different river)

Hardly news! A quick search, shows that booking has been necessary for years. https://canalrivertrust.org.uk/notices/9123-keadby-lock is a notice from 2016 stating that 24 hours notice is needed, it was replaced by https://canalrivertrust.org.uk/notices/9532-booking-information-keadby-lock . i suppose that blog must have received the latest update, https://canalrivertrust.org.uk/notices/16230-booking-information-keadby-lock , two days ago.

Just to make it absolutely clear, I have no connection to either the manufacturer or the retailer I linked to. I only added the link as it seemed to be a valid answer to the question posed.

For a different take on the signs in Devon, have a look at https://www.devonlive.com/news/local-news/horse-drawn-barge-near-misses-3182200 .

Advanced Mobile Location is available to the emergency services, as long as the phone used is recent enough to provide it, https://eena.org/aml/ . https://eena.org/wp-content/uploads/2019/07/2019_07_17_AML_Report_Card_Update.pdf (68 page PDF) says 60% of calls in the UK do provide a location. This will no doubt improve as people replace their phones.

No idea! However, at a guess, I wonder if getting involved in high profile events is so that the technology gets noticed & can then be developed as a production solution. They are also providing the charger for the VW ID.R https://www.aquafuelresearch.com/ & https://www.volkswagen-newsroom.com/en/press-releases/a-vessel-for-technology-beyond-motorsport-the-charging-of-the-idr-system-5041 .

Unless they have changed since this article, they are modified Diesel engines using a byproduct of biodiesel production https://www.fiaformulae.com/en/news/2016/june/insight-formula-e-s-emission-free-charging/
