Is it possible to steam steak?
You could do it, and it would certianly cause the meat to be cooked. However, I suspect it would lead to a less-than-tasty result.
There are two potential issues here that I can see:


If you're steaming, the temperature maxes out at 100 degrees Centigrade. This leads to longer cooking time, and a "washed" look. Think of how the chicken meat looks in chicken soup.
You'll be losing the Maillard reaction, which is what gives that lovely outside texture to anything fried. This is because of the relatively low temperature of steaming, and the lack of liquid (oil) to react with.
