紧急动力 - 生存风格
What would you say if I told you it is possible to build an effective simple battery charger for an emergency backup battery that is cheap, has no moving parts, has no generator, works day or night, and has no solar cells and when weather conditions worsens, the better it works?
What if we could harness this free energy and use it to our advantage after an emergency event such as a large-scale power blackout, or after a hurricane when we have no other methods at our disposal to charge our emergency batteries after such an event occurs?
What if I told you that most hams already have the main components of this charging system already installed at their operating locations?
Most all of us have learned to pick up our coax and to tap the PL-259 connector against the case of the radio or ground to bleed off this charge before connecting it to our radio equipment.
我们曾经被迫陷入困境，必须考虑我们如何将这个日常静态问题转化为自由能量？
It is a well-known fact that enormous charges can build up on long wire antennas and the longer the wire the more charge that it will build. Most hams think of this as a disadvantage. I would like to further explore the possibility of how we can turn this into a distinct advantage for both emergency backup power and wilderness radio energy requirements.
我知道我们的天线应该拦截从天空下降的垂直直流电流。这通常代表几个微放大器的高电压（天线越高，位于地面，天线上的电压值越高。）
我们可以通过尝试这种小实验进一步验证这些信息，只有火腿运营商实际上只会被捕获：
First let’s hook up an NE-2 bulb from the antenna to ground, and then watch the bulb in a dark room. It should start blinking repeatedly. Once you see the bulb flashing, try hooking a few more NE-2 bulbs in series to determine how much power your antenna wire can produce. For those that may not be sure what an NE-2 bulb might look like, here is a photo:
You can “approximate” the voltage available by adding more NE-2 light bulbs into the circuit chain until they won’t flash anymore.
In this experiment, we can assume that each bulb adds about 100V to the trigger voltage. If you can persuade a series chain of 10 bulbs to blink, then your antenna is probably putting out at least several hundred volts, maybe even a 1000V!
让我们选择一个良好的海洋电池来启动这个项目。海洋电池通常比普通汽车电池更长的电荷。普通汽车电池可以放松一下，只需一天坐在近2安培的速度即可“...这意味着珍贵的备用电源就会丢失入薄空气！我们在这种情况下的目标是尽可能长时间地将紧急备用电源存储在储备中。
一般来说，在“储备分钟”中评级的电池通常比在“曲柄放大器”中额定电池的电池比较。
接下来，您需要一个工作的火花塞。我更喜欢V沟型，但任何旧的火花塞都可以正常工作。首先将火花塞尖端连接到天线线的末端（稍后描述的天线线），然后将火花塞（其中螺纹的地面）运行到12伏汽车线圈的顶盖中。任何旧的销售工作线圈都会。（当然，除了你的妻子目前在她的车里使用的那个。）
对于该项目仅选择绝缘天线线非常重要，因为这将是最佳的。电线应完全绝缘从端到端，在任何地方都没有断裂或焊接连接。无论将其放在直线上，它似乎没有任何区别，是一种环形的天线配置，或者如果它来回编织。长度是关键，而不是其占用尺寸。
Old discarded phone line, old cable TV coax, practically any wire that is insulated and long will provide satisfactory results provided that you don’t tear the neighbor’s cable TV wire out of his lawn, you shouldn’t have any problems using any type of insulated wire for this project.
To connect the coil to the battery, we will use the bottom connector of the automotive coil that is normally connected to the points in your car. This will now be connected to the positive side of your emergency battery. The negative post of the battery is simply hooked up to a good earth ground.
You can make this work in field, wilderness or portable radio operations by driving a temporary ground rod into the earth and then connect the ground directly to the negative post on your battery.
接下来,我们安装一个1到3 KV电容器。的capacitor value will work best if it is around a few pico-farads like those typically found in the horizontal section of a television chassis. The capacitor is then connected from ground back to the wire where the top of the spark plug is connected to the antenna.
Nothing should be touching ground except the ground post of the battery. Approx. 200 feet of insulated wire will completely charge a 12 volt deep cycle every 2 or 3 days! A thousand feet of wire will do it a lot quicker but the voltages will approach lethal levels.
这是充电系统的作用，因为长天线线的作用类似于在天线线上构建电荷的电容器。当达到几千伏时，它将通过在火花塞上“火花”来放电。然后火花塞将电荷传递给线圈，这反过来“将”将其降低到几百伏特。然后将电力从线圈注入电池中。线圈通过以规则的放电间隔将电荷“脉冲”电荷的工作。
The weather controls how much static electricity is in the air at any given time during the course of the day or night. This electricity is then made available for charging our battery.
The real advantage of this particular charging system during an emergency situation is that the worst the weather gets, the more electricity you will have at your disposal for charging your battery.
When conditions such as wind and super cold air are frequently persistent, you will be able to weld the fillings in your teeth together! …Be careful!
越高，您获得了隔离线的绝缘电线，它将在捕获来自空气的DC电流的工作越好，这对于这种高效，但低成本的应急电池充电系统。
