What is the main challenge of creating energy based weapons?

967 viewsEngineeringOther

For example: laser rifles or pistols, anything that shoots out concussive energy that you see in sci-fi shooter games. This is obviously in the realm of science fiction but I can’t imagine that kind of technology is impossible to come by. With those weapons they can probably hold up to hundreds of rounds worth of energy/plasma/etc.

What would be the main roadblock with this kind of weaponry?

If you want them to do a lot of damage, they need a lot of energy. 

If you need a lot of energy, you build the weapons into a huge power source. 

If you want them to be portable, then you need a huge power source which is also portable and has so much capacity that it can keep supplying power at full effectiveness for hundreds of rounds…

…and that doesn’t exist. If it did, electric cars would be using it too, for example.
