When the discharge rate is faster, as it probably would be in a coil gun, the available energy is not as great but even under intermittent heavy pulsed loads, the battery will provide around 5,000 Joules.

Thus, we see this relatively small battery has several times the energy of even a high powered bullet.

If we set our goal for a more modest velocity of 600 ft/sec (183 m/s) and a 3 gram projectile, the kinetic energy will be 50 joules. In the following analysis, we\'ll keep the 50 joule goal in mind.

The Magnetic Gun Club的资料，证实电池的高效和持久

楼主大概是受到了工兵野战用的起爆器的启发……

主意不错，但事实上非常不妙，因为要给足够大的电容充满电非常消耗体能和时间，下午我用一个直流电机带动一个高压发电机试验了一下，在转速大约500转/分的情况下，发电机输出750VDC，给800V，3000UF电容组充满电需要接近3分钟时间，不要忘了，那是电机带动，要是手摇，半小时怕也满不了。不信可以找个500V摇表试一下。

不会吧，电机的电流太小了一点吧，电池升压充电也用不了这么长的时间。

手摇的功率可比电池大，发电机内阻和充电电压也要调试的。手摇机器应该是可行的。
