Personally, even with the May 27th pole shift date come and gone, we are continuing preparations - we have added to our freeze dried food and seed stores and we now have multiple systems to collect water, store water, purify water and heat water and are currently working on the bicycle powered air infiltration system to our shelter as well as have added two 4 x 10 solar panels to the shelter roof to produce water, have purchased two 120 photovotaic panels to make electricity with along with a charge controller and deep cycle RV batteries, and now have a bicycle generator ( a really nice unit found at www.windstreampower.com ) to produce electricity should there be no sun along with two 12VDC to 120V invertors for running small appliances and even the washing machine.

就个人而言，即使2003年5月27日---极移的日期来了又溜走，我们还是在继续做准备----我们已经增加了冷冻干食品和种子的储存量，并且有了收集，存储，净化和加热水的复合系统设备。我们现在正致力于为避难所建造由自行车供电的空气渗透系统，还在避难所的屋顶上加入了2个4x10的太阳控电板，以便制造出水源。我们也购买了两个120光生电池板和两个充电控制器，以及可多次循环使用的 RV 电池，用于供电。现在我们已有了自行车发电机（在 www.windstreampower.com 上发现的一个很不错的东西），没有阳光的时候用于发电。

At the same time, DG4 can kill bacterium perfectly, the bactericidal ratio to sulfate-reducing bacteria and iron bacteria is 99.8% and 98.9%.According to the results, it can conclude that DG4 is a new highly effective corrosion and scale inhibitor and bactericide. Besides that, DG4 is more economic and environment-friendly.
