I think you should start with a foundational sort of element that a person should not be seen to benefit from public funds. There's a requirement in the Sustainable Development Technology Act that says that no one should personally benefit from government money. However, when the act also then requires that board members have expertise in the field, that requirement, by its very nature, invites conflict of interest. The clean-tech industry is a small one, so if you want some expertise, it's likely that the people with that expertise are also trying to develop and innovate.
That's why there's a need for a really rigorous process to say that if you've declared a conflict of interest, you should do the right thing and recuse yourself from the votes and the discussions.
