There is an Open Source Death Star project on Kickstarter proposed by www.gnut.co.uk
They already collected £238,758 for the “project”. 771 people donated £1 or more, and 1,548 donated £10 or more.
£20,000,000 for more detailed plans and enough chicken wire to protect reactor exhaust ports.
£543,000,000,000,000,00 ($850,000,000,000,000,000) to secure full funding for actual construction.
To keep costs lower the entire project will use open source hardware and software.
Risks and challenges
The only risk is the power of the Force.
The main challenge is assuring Kickstarter that this is a joke and not a serious project. As proof, the goal has been set high enough to make successful funding almost impossible.
