The Hyperloop Advanced Research Partnership (HARP) is the nexus for hyperloop information, research, and stakeholder collaboration. HARP was formed to help the hyperloop industry reach its potential of building a transportation system that is more efficient, sustainable, secure, connected, and resilient. Creation and operation of hyperloop technology involves diverse stakeholders – from many industry sectors, to all levels of government (local, state, regional, and national), to university research groups and individuals. HARP provides a framework for stakeholders to gather, share ideas, innovate, and collaborate in ways that support both individual and collective efforts to grow hyperloop capabilities.
