Dragons' Den (2005): Episode 4

Dragons' Den is back and is open for business. Peter Jones, Deborah Meaden, Touker Suleyman, Sarah Willingham and Nick Jenkins take their seats to face a fresh batch of entrepreneurs who dare to enter through the Den doors. In this episode, tensions are running high as an entrepreneur ruffles some feathers in the Den when he fails to clarify his restaurant business model, a husband-and-wife duo fight to defend their innovative drilling tool gadget, and it is sink or swim for a businessman pitching his portable water-saving product. But will any of the Dragons see the potential in his eco-friendly design, or will they wash their hands of it?
