My idea is to build solar farms at strategic intervals to allow electric vehicles to recharge while covering distances greater than is currently possible.

Most outback roads have considerable distances between re-fuelling locations and we need to reduce dependence on fossil fuels. By building electric cars we achieve that required reduction but currently the distance that can be travelled on one charge is limited. We also have sunshine, and wind, in areas which have no habitations, but if we take advantage of this fact by building solar farms, plus, possibly, wind generators and solar thermal generation (which can ensure 24 hour availability of power), providing opportunities to recharge, long distance travel using electric vehicles would cease to be a problem. An additional benefit could be that these solar farms could form a hub for local activities facilitated by the power being generated, since the power produced and not stored immediately is readily available while the sun shines.
