Packing Peanuts and Corn Ethanol

in , ,

It is hard to figure out the full cost of the government’s corn ethanol mania. Random observations during the holiday season suggest that they are still larger even than reported already. A full accounting, if it were possible, would sound a cautionary note as a new congress and a new administration consider how to stimulate new energy and E-Tech.

The most believable numbers suggest that the full production costs of corn ethanol use more oil-based energy then it replaces. These numbers are of course, in dispute as they include assumptions about fertilizer production and tractor driving and a twisted maze of hidden subsidies. Holiday packing peanuts are part of the picture....

A pricing Service for Electricity

in , , ,

What price structures are necessary to enable fully symmetric negotiations over power purchase and sale? Over at the NIST TWIKI, Marty Burns, Bill Cox, and I ironed out the requirements for a pricing service for electricity. Comments are welcome.

What are the requirements for communicating price across the smart grid? What pricing structures are in use or under development now? How do we move to a common information element, common whatever else needed for prices?

Note: It is important to emphasize that these are requirements for a solution set for pricing services. Therefore all the following requirements are not necessarily simultaneously applied to any particular single service based on the ensuing model.

Gamboling through the Clouds

in , ,

Some months ago, I wrote about how Software as a Service (SaaS) was going to be used in building controls. The UNC Enterprise Building Management System (EBMS) and Hosted Controls already use that model for monitoring and operations of building systems. Others like Sensus offer building analytics and knowledge-based maintenance from their own data center. Now Harrah’s Entertainment, the largest of the casino operators is moving into the clouds, and the outcome may change building systems again.

It has been best practice for a while now to interface building systems to hotel customer operations. The check-in process can...

Smartgrid Basics: The Demand Side Problem

in , , , ,

Last week the Smartgrid-discuss group opened up within OASIS, introducing power grid technologies to the architects of e-commerce and internet security standards. Some of the latter are trying to understand the problem, and learn the jargon. I wrote this as the second of a series of posts introduce the issues in a simplified, almost cartoon form.

Building systems have traditionally been invisible and uncontrollable. They have been managed to reduce costs with no real focus on the service they are providing. They have grown up in sandboxes, using their own peculiar protocols. These protocols are deep and technology specific, and often without effective interface. These systems are operated, when they are operated by process specialists.

Building occupants rarely have a precise understanding of how these systems affect their business. They may know exactly what...
