I think we can all agree that Solar Panels, LED lighting, USB charging and of course Safefill have made a real difference to us. By us, I mean everyone. These things have given all of us a real choice, whether we want it or not, where before, if you were to go off grid, you were reliant on keeping your battery/s charged by what ever method you chose and that could be taking it for recharging by the site, plugging up to the towcar, carrying a spare in the car and running around to charge it etc. Now, with the SP, those actions can be consigned to history. Not only that, the accessories that we use in everyday life now are of little draw on batteries with again, LED lighting, phones, tablets, toothbrushes etc being charged through USB, low wattage heat pumps etc while the Safefill takes the brunt of the hard work providing heating, hot water and fridge- we owe so much to the modern technologies - they did not come easily- the LED for instance was a long and hard road and although the LED was invented in 1927 it was of no practical use. Various improvements were invented from time to time but it wasn't until as late as 1994 that Shuji Nakamura having worked tirelessly came up with the LED we know today - and it was the faith and dedication of that man who bought it about and now look where we are. A tenth of the battery power we used to use and just as bright if not a little better- well done and thank you to that pioneer! and I am, eternally grateful to Safefill for sticking to their guns and fighting hard for the last 7 years against the big boys. They must have felt like giving up at times(Safefill not the big boys 😂) but they haven't and thank goodness they didn't. There is an important meeting this week between SF and Morrisons! Watch this space!!. Since I became a full offgridder, things have got better all the time in the technology field with more efficient SPs but particularly- cheaper SPs! I believe modern techs will continue to improve to a point where even the deepest heel against non EHU will start to slip. We live in a time and with inventions that our forbears could only sit and dream about. Can you imagine talking to your dads and saying "Yes, and there this panel that we can put on the caravan roof or fold out to face the sun and it makes electricity completely silently and all it needs is light! " "Oh and there is a fitting instead of a lightbulb that takes a tenth of the power to light the van" Can you imagine what they would say? I find the new techs very very exciting and the possibilities of them are staggering. Makes me wonder what the next generation will have?? Any (sensible) suggestions?😀

Lightweight batteries taking up very little space? That solar plane that went round the world must have used something not out here yet? For sure they didn't lug batteries around and weren't always in a position to ground themselves if the sun didn't shine a lot? The panels themselves must have been lighter than most too I should think. I hope my son doesn't read CT he would expect me to know more since he did some training to help one of the pilots with his sleep!

my brothers new Li-ion golf battery is the same capacity as mine, is half the size, weighs about a quarter of mine but cost around three times as much....
the tech is getting there but its still early days and costs are too high for many.

Pippah and BB, I think you have a very good point. Battery tech has come on a long way and is still developing. I think it's the major field for development as far we are concerned. I was reading of a Sodium battery the other day but again, the technology isn't there yet but they are getting there with collaboration between the Chinese and the Yanks. What the weight is like I don't know but if they are anything like the Li-Ion weights they will be good. Sodium = Salt= plentiful supply = cheap power= yeah right! Certainly SP tech is still improving and they reckon another 25% efficiency by 2025. - not because there will be more conversion by the panels (although there may well be) but more that the production of the panels will be so much better and will decrease flaws that lose power now. I wonder if new materials will be developed for electric motors for driving pumps etc will improve electrical efficiency? As far as I can see, there are three avenues that will improve our hobby. Better absorption and conversion rates of light through SPs, equipment that takes less amps to run and battery technology improving yet more. What do people think of Li- Ion batteries? On the surface they seem to be excellent at taking and holding charge, Like for like, they are a third of the weight and give twice the amps that a wet 110ah gives. You can completely discharge them and charge them back up again, they are good for 5,000 cycles rather than 400 - 500 in a lead acid battery. They give the same amps through the entire discharge of the battery - they are excellent at storing charge from a solar array apparently- and the best bit, although they have a bigger up front cost, they are cheaper overall to lead acid batteries- call me a cynic - there has got to be a flaw somewhere- what are they not telling us?

Posted on 21/08/2017 20:17 by BoffI must of forgotten to mention got a stove stop expresso pot as well as the cafetière. Got a jar of Nescafé as well for the full fake coffee effect as well. But if you need believe that the best coffee comes in a mass produced pod then frankly jog on.

Meanwhile away from smelling the coffee. After 8 days off grid @£7 per night. Now pay £14 per night and get the use of the microwave. We didn't empty the safefill so estiminated cost approximately £1 per day For gas
Go to the Welsh national rally in a couple of days another 5 nights non ehu.
