They do a good job removing excess moisture, but once one gets into the car the condensation from 3 people breathing quickly fogs the windscreen.

I have two large socks and recharge them every month or so, when they start to feel visibly wet. If it rains a lot (I'm in Britain) I may have to do it every fortnight. Take out the crystals and put them on a tray on the oven with the fan on for a couple hours.

I like the "All dash" idea. How many Kg does it take? I'm currently using about 1Kg on each sock. As mentioned this is just about enough to prevent condensation if it is not raining outside and I'm the only one on the car. All other cases, dehumidifier on.

Cool. Can you disable the DC-DC converter on the Prius at all? I have mine in manual mode for when its needed. The 40Ah LiFePO4 feeds all the 12V loads. Driving 27-30 miles seems to use about 35% of capacity at night if I keep the Blower fan off (I need to replace the variable speed resistor with a PWM circuit). The terminal voltage is also higher (stable 12.5-13V).

I'm curious. Can you give some some more details? How much moisture do you remove on a typical 30m drive? or do you keep it on when plugged in?
