Your solar battery charger warped? It must have had some extra special poor design qualities! You were very unlucky with that. I have never heard of a solar device warping before. I can only presume it was poor quality plastic. My solar charger sits on a window sill, in a small warm room, above a heater and a UPS and has not warped in the year that it has sat there - and there are usually batteries in it. I have had problems with conventional chargers in the past. Usually due to battery leakage that has corroded the charger. Stepping 240V down to 1.2V is not easy! Yeah, it was just cheap, poor quality plastic. Im sure that the more expensive ones are much better. |

Your car's electrical system creates (from the fuel burning in the engine) only as much electricity as is demanded at any instant. So- place extra demands on the system (lights, wipers, fan, defroster, radio, various chargers) and you will make the engine work harder to produce that electricity. Sorry to bring you the bad news. What happens when you put the clutch in? I thought the flywheel would still charge the battery. OK, this only happens now and then, but when the clutch is in, the engine just ticks over and no more, but I think it still charges the battery when it is doing this. I'm raising this point because I think this is a serious area that could save energy if car manufacturers could be bothered. Car engines still need to run when sitting at traffic lights, in a jam, or just pulling over for 2 minutes. So why not ONLY charge the battery at this time? My battery never goes flat or anywhere near it. I assume lots of energy is continuously wasted keeping it topped up, unnecessarily. My guess is that using 15% Efficiency Solar Panels a car could easily produce 1KW of energy in average conditions and during sunny days this could be 10KW. I don’t know how far that could pull the average car, but it would certainly keep the battery charged! |
