Stocking up on gold bullion to get you through the impending financial apocalypse? Don't forget your electricity needs, easily satisfied by the $5000 Solar Stik portable wind and solar power generator. The 80-pound twin solar array and wind turbine generates 80 amp-hours a day as long as the sun shines and wind blows.
Team this up with a few good batteries, and you could run a vacuum cleaner long enough to clean up all that broken glass. Add guns, plenty of ammo, and a case of whiskey and you might last at least until the rest of the food runs out.
