Is it possible to use WolframAlpha servers to evaluate equations in Mathematica v8.0.4?

Is it possible to use WolframAlpha computational power to evaluate equations in Mathematica version 8.0.4?

The thing is, it takes ages for my computer to evaluate certain equations. It would be great if I could use WolframAlpha (or something else?) to compute these equations .

The WolframAlpha function gives to access to Wolfram|Alpha in Mathematica. Just like the Wolfram|Alpha web interface, there is a time limit on calculations. Also, you can't run arbitrary Mathematica programs. You need to use the "standard" W|A inputs.

While you can extend the time limit by subscribing to W|A Pro, I think what you are looking for is cloud computing services that support Mathematica. Here's something I managed to google up:
