What technology will have to be reinvented in a grid down world?

    I thought I would start this group discussion by figuring out what will have to be recreated in a grid down world. I believe water collection and distribution will be high on the list. Wether this is is accomplished by windmills, rain collection, or alternative power sources, the need for reliable clean water for a community would be the difference between making it or not.
    Out here on the prarrie windmills are used a lot they are fairly simple technology, and I believe they would be easy to recreate and use in areas that have a high enough water table.
    Area's that are fortunate enough to live near lakes and rivers may only have to construct pipes or aquaducts to redistribute water to the community. How would you accomplish this?
    What other technologies do we need to addres?
    Power generation would be a biggie or tool making / blacksmithing? who's got idea's on building forges?

    I think metal working would be right at the top of the list as well. In a grid down world, the existing metal still exists, so there will be at least a short term supply of workable metal that needs to be transformed into whatever tools or PARTS are needed.
    Animal husbandry , botanists/herbalists, and TEACHERS. I mean a person who has the gift of teaching
    Country doctors that sew you up with a carpet needle, horse tail, and cover the wound with honey and send you back to work.... will probably fare better than doctors that have to rely on lab tests and MRIs to determine what's wrong with you. That might lead to a Veterinarian being more valuable than regular doctors......after all, vets have to diagnose patients that can't describe what's hurting ....at least not verbally.

    Of course I gotta book in that...Oil drum forge

    Other technologies needed would be fuels. Biodiesel, alcohol fuels ect, easy to make, you would be able to get vehicles going. The local general store would have to reappear with most all items produced locally. Clothing, seeds grains....

    Of course, the general store would have to include classes on "how to" for the masses that are lost without microwaves, convection ovens, and fast food. Likewise, there'll be a need for teaching 'city folk' all the things that country folk just know....penny sized brown pellets near your garden mean that venison is scheduled. Small marble sized black pellets mean that Thumper is on the menu. Little oval sized droppings mean that you need to sit up late with a .22, or set some rat traps.......birds in the garden mean fewer bugs in the veggies.....y'know, common stuff.

    Salt extraction and transportation. There are no natural salt deposits close to where I live, after my stores are used up salt will become a necessary resource. How long after a grid down situation would it take for the general stores to start receiving regular shipments of salt, sugar, flour etc,. Also, how are people going to get to the general store, in my estimation the closest town to me that will be the first to start with somewhat normal services will be over 30 miles away. Maybe the traveling peddler will make a comeback.

    Some interesting topics here .Metal working, fuels, Salt extraction and transportation. To me all of them are very important and would also be very valuable trade items. Especially salt, I remember reading that salt itself use to be treated as currency especially in the days of Rome.

    I'm sure everyone's read up on Dave Gingery's series of books, the man was a genius. Salt extraction is a tough one. Seems like if the grid went down, it'd be wise to have a small power inverter/battery and either solar, wind, or water to at least make power tools available instead of wasting manpower/calories with hand tools. In the interest of conserving water/salt/food ect, seems a small, purpose built electric supply for odd jobs would be a good priority, drilling holes by hand is a PAIN!

    As an example, I've used a H. Freight cheapy 200/400w inverter on an economy car battery to power a 1/2 electic impact for around 250 ft/lbs, it was alot easier than using a breaker bar.

    micro hydro generators and solar steam generators look promising if someone has a ready supply of moving or standing water nearby.
