In enterprise calendaring, conference rooms were originally added to corporate address books as if they were another person. An account was created in the corporate directory for each conference room, albeit an account that lacked an employee ID. This account was assocated with a calendar server and perhaps an email account. Conference rooms were set up Justas were senior staff that do not manage their own schedule. Anyone could invite the conference room to a meeting. An assigned administrative assistant received all schedule requests.
]]>The power industry of North America has provided its customers with the greatest life style that any civilization has ever had. The old service model assumes an ever-present supply of power that is predictable, abundant, and inexpensive. World-wide, our plans are to reduce the power supplied by predictable an inexpensive power sources, to replace them with power sources that are intermittent and less predictable, and that are widely distributed across the grid, including within homes, businesses, and neighborhoods. The old service model will not survive...

]]>Some colleagues and I were discussing the improbable demonstration in Bologna on October 28, the demonstration of Andrea Rossi’s e-cat system. As I write this, responses range from exuberance to cries of fraud and, guardedly, some comments that he might have pulled it off. E-Cat, which is protected today by trade secrets rather than by patents, claims to create a reaction between Hydrogen and Nickel to create Copper…and a self-sustaining amount of energy. Dr. Rossi aimed to demonstrate a 1 MW generator; he demonstrated something less than half of that; and reasonable skepticism runs high.
However that plays out, the question is one I have pondered before. The E-Cat system creates heat. That heat is used in the usual ways to create electricity. If you had an unending heat source behind the house, then it is unlikely you would use it all for electricity.
I have a friend in the center of San Diego who is going off the grid using a fuel cell. It may not make economic sense, but he dislikes his local power company. He wants to be self-reliant. He plans to run his meter backwards because he can. He is using conventional off-the-shelf technologies. What he is pondering most, though, is the heat.
His conventional fuel cell generates heat from combustion, and spins a little turbine. He then must she the heat, and run again. On campuses and industrial sites, we take advantage of this heat for cogeneration. He wants to do the same.
Being in San Diego, he first began considering shedding heat into his Jacuzzi. His plans then moved to thermal exchanges with his domestic hot water system, and with the heat exchangers in his HVAC. He lives, though, in a temperate area, and uses most of his energy for cooling. For these, he uses conventional heat pumps, which use plenty of electricity.
His fuel cell, though, generates heat first, and electricity second. Absorption Chillers might make much more sense for him, but today, there are few sources for no-maintenance absorption chillers for the home. Some use them to cool as a use for solar thermal, but that market is aimed more at the energy hobbyist than at the high-end set and forget consumer.
For years, I have though that every data center is a thermal energy source. But last Friday, as something that appears to be the descendent of cold fusion was publicly demonstrated, albeit with close control over how well the public could observe, I thought about abundance, and how we might re-arrange our homes, or offices, and our cities around cogeneration everywhere, and around harvesting what we call waste heat today.
Today, the heat that makes our electricity is far way. For each of us, we start with electricity, and layer thermal energy on top. But what would we do, what equipment would we make, if we could each of us, in each building, start with thermal energy, and layer electricity on top.
]]>Energy Interoperation is nearly complete. The OpenADR Alliance will build an industry around the event oriented profiles of Energy Interoperation. New business models and new interactions will spring from the transactive profile, TEMIX. We now have market interfaces for smart energy. The largest problem that remains is finding the market.
]]>I know it is hard to keep up with the specifications and changes; I can barely keep up and I am putting the smart grids specifications out there. What follows is a brief summary of the road to OpenADR 2.0.
OpenADR 1.0 is out of date.
OpenADR 2.0 is almost here. It relies on the joint work of xcal/ws-calendar for its time/schedule communications. This work was done in joint effort by an IETF-centered group (CalConnect) and by OASIS
In the IETF:
Standard schemas for the above can be found in the namespace document of the current Public Review of WS-Calendar (ends on the 14th)
There are open-source implementations using these specs. VAVAILABILITY is only a draft in the IETF, but we rely heavily on it in EMIX and Energy Interoperation. If you are using communications tied to smart energy or to facility use, I reccommend that you read that specification.
For describing product, price, and market terms, Energy Market Information Exchange is used. As so much of EMIX is communication of schedule, it relies heavily on WS-Calendar conformance. This specification is also out for public review, until the 26th.
OpenADR 2.0 is a profile of Energy Interoperation. That specification is soon out for Public Review. You can find “pre-review” versions at:
One thing that the work lacks is discovery. EnergyInterop is designed to be recursive, so a utility or aggregator might expose a VEN interface up to the wholesale market, while exposing a VTN surface down to the home, office, industrial site, or microgrid. Each of those exposes a VEN on the outside; each may, in turn, choose to use EI internally, with a VTN communicating with numerous VENs.
Some interesting work is attempting to extend the model of OpenADR/Energy interoperation down to appliances and devices. This will place a greater premium on Discovery.

In Committee, we have talked some about WS-DD as a possible mode, but have not gone beyond the simplest discussion.
