I think that it is possible to make an electric Semi-Truck. This is a idea that is thrown out by many. People argue that the power is there, from the engine, to move the truck, so in that aspect it is possible. But they always point out one thing: The power supply. The batteries are not large enough to power the engine for very long. So there is not enough of a range of travel before you have to recharge the batteries. It would take a lot of time to recharge them also, so it would take a long time to deliver the product.

But what if each axle was, or had, a generator? The engine only has to power one axle in order to move the truck. Why not use the three to five other axles as generators? Why is this not possible? So in theory, wouldn’t you be producing three times as much, or more, of the power that is being used to move the truck?

This would be very effective when you are driving on the freeways, as the wheels are turning a lot. Also, once you reach a high speed, the engine doesn’t have to do so much work. Thus, you wouldn’t need all of the energy being produced, and you could easily recharge your batteries and listen to some music at the same time.

Also, in hybrid cars there is a device that charges the batteries as you brake. Now, I don’t know exactly how that works, but I am sure that the harder you brake, the more energy you produce. Also, the more weight that you are stopping might contribute to the amount of energy produced.

In trucks, there are brakes on several axles, including the trailer. So, if you are stopping over forty tons of goods, with more than one axle, you can also produce a lot of energy there. So this would be an effective way of driving if you are in the city.

So all that seems to be the problem with creating this product is that nobody wants to put the money into it, right? Well, this seems to prove that the electric Semi-Truck is a very possible thing.

I know the highest power laser available to the public is 300mW. That can pop balloons at close range and cut tape. How powerful would a laser have to be to injure or kill a human being on contact?

I'm reading a document and It has the following in it;
"This module also contains a snubber circuit for limiting voltage spikes across the free wheeling diodes and a mousetrap capacitor used to absorb high frequency, high voltage transientsinto the chopper."
