Why cant we have phasers or laser blasters like in sci-fi movies instead of guns?
In: 5
They require too much energy/power.
Currently we don’t have any batteries that can hold that much energy while being small enough to be portable. Also, we don’t have energy sources (generators, etc) that can produce that much energy and also be small enough to put into a gun or something.
We do have the capability to make lasers and stuff, but they are very large and require entire buildings, generators/special power plant, etc. The US has even tested putting lasers on airplanes to shoot down enemy missiles… but it’s still not super portable or efficient, and it’s prohibitively expensive currently.
Maybe someday… but not yet. Lol
