Legally, we are required to ensure that donations made in a project's behalf are used towards those activities. We are a charity and we have certain responsibilities to donors and to the IRS to fulfill a donor's expectations of how a gift will be used once a donation has been made. If a project cannot fulfill its plans, we suggest that you use any funds you have raised to cover all associated project expenses (even if it didn't yield a finished product, there are usually expenses incurred along the way that you can use your funds to pay). We cannot simply cut a check to you without a project related expense listed as the purpose for those funds.
