How many hyperconjugating strutures are there for the following compound?

enter image description here

I thought the answer to be 8 (as there are eight alpha hydrogens) but the correct answer given is zero. Why isn't the answer eight here, as expected from a $\ce{C=C}$ alkene? Does the explanation invoke the very definition of hyperconjugation?
