We describe an approach for how to design an essentially more scalable, flexible and resilient electric power infrastructure – one that encourages efficient use, integrates local generation, and manages demand through omnipresent awareness of energy availability and use over time. We are inspired by how the Internet has revolutionized communications(More)
—We develop a flexible and responsive electrical load in the form of domestic refrigerators augmented with a thermal storage system, a wireless sensor network for monitoring and actuation, and a controller that enables response to external controls. Using this, we investigate the potential of such loads for two applications: price-responsive demand and(More)
In 1989, the RAID (Redundant Arrays of Inexpensive Disks) group at U. C. Berkeley built a prototype disk array called RAID-I. The bandwidth delivered to clients by RAID-I was severely limited by the memory system bandwidth of the disk array' s host workstation. We designed our second prototype, RAID-H, to deliver more of the disk array bandwidth to file(More)
The United States electricity grid faces significant problems resulting from fundamental design principles that limit its ability to handle the key energy challenges of the 21 st century. We propose an innovative electric power architecture, rooted in lessons learned from the Internet and microgrids, which addresses these problems while interfacing(More)
We have shown a prototype user interface for the InfoPad, a portable terminal with multi-modal input and multimedia output. We believe that many of the people who could benefit from inexpensive, portable, networked terminals are not computer experts, and we are therefore designing the InfoPad and its user interface to be more like a notebook than a(More)
RAID-II is a high-bandwidth, network-attached storage server designed and implemented at the University of California at Berkeley. In this paper, we measure the performance of RAID-II and evaluate various architectural decisions made during the design process. We first measure the end-to-end performance of the system to be approximately 20 MB/s for both(More)
The InfoPad project explores the infrastructure and devices required for portable wireless access to the national information infrastructure. The InfoPad model emphasizes high-bandwidth wireless connectivity and moves the computing power of the portable device into the backbone network, where we can provide not only full internet access, but increased(More)
Information technology has transformed itself many times over the past decades. Yet a far more fundamental overhaul is in the making − the long‐predicted world of fully ubiquitous computation and communication is finally emerging. Addressing the associated challenges and opportunities may require us to fundamentally re‐think the way we do design. Most(More)
The Internet of Things (IoT) represents a new class of applications that can benefit from cloud infrastructure. However, the current approach of directly connecting smart devices to the cloud has a number of disadvantages and is unlikely to keep up with either the growing speed of the IoT or the diverse needs of IoT applications. In this paper we explore(More)
