Abstract: In some aspects, the techniques described herein relate to a method including: aggregating data for use in an interoperable P2P application; transferring funds from a user's account associated with a first disparate P2P funding application to fund an account associated with the interoperable P2P application; transferring the funds from the account associated with the interoperable P2P application to an account associated with a second disparate P2P application; initiating a transfer of the funds from the user's account associated with a second disparate P2P application to a colleague's account associated with the second disparate P2P application; and recording transactions carried out by the interoperable P2P application in a ledger system associated with the interoperable P2P application.

Abstract: A machine is provided for combining thin flexible solar film panels with a metal sheet to serve as a roof panel for a building. The machine has reels for holding rolls of metal and solar film. The solar film panel has an adhesive with a backing for protecting the adhesive. Means are provided for unrolling both the metal and solar film and for removing the backing from the solar film panel. A mechanical brake device is provided for parting the solar film panel from the adhesive film at the desired length which is sometimes shorter than the length of the metal sheets. A recoiler is provided for removing the backing from the solar film panel. Pressure rollers are provided for pressing the solar film panel to the metal so that the adhesive binds the film panels to the metal. The rollformer component cuts the metal into sheets and configures the metal into the desired structure for the roofing panel.
