Here it workes well...

The concept itself is not bad... and will definitely work if you use
some solar cells to get a little energy.
(BTW: This idea is not new. This design was already described in a
humorous story in New Scientist at least 20 years ago).

But the speed will be sloooow, not to mention the size of this craft
if you'd like to have some payload.
Simply using a ship (maybe with sails?) will probably not be much
slower, and pretty sure it will be a lot cheaper.
