For persons who do not want to engage in corporate sponsoring or club memberships, but want to give us some kind of informal support, because they want to see the project to progress.
Just drop a few cents of material real world support into our paypal account to keep us going. We will convert this support into small scale pilot projects of general interest to move concrete floating projects in the sense of concretesubmarine.com forward.
If you want to do "something more specific" or "something larger scale" or "some kind of formal cooperation" - please contact directly.
