Company Receives Patent for Podcasting

first_imgVoloMedia, a podcast analytics, advertising, and distribution company, just received a patent for “providing episodic media,” including podcasts. According to the company, which filed for the patent in November 2003, U.S. Patent 7,568,213 covers all episodic media downloads, not just the RSS-dependent downloads that power today’s podcasts. VoloMedia CEO Murgesh Navar says that the company doesn’t plan to go after individual podcasters, but that the company plans to “work collaboratively with key participants in the industry.” We do wonder, however, if VoloMedia can really claim to have invented podcasting in 2003, given that the concept was already under development by Dave Winer and others in late 2000 and early 2001.The only company mentioned specifically in the announcement is Hulu (as an example for a content platform that might one day offer episodic, downloadable content), but in an interview with NewTeeVee’s Chris Albrecht, Navar also revealed that the company is already in talks with Apple and a number of TV networks.Prior Art?While the patent was filed in November 2003, it is not clear when exactly VoloMedia argues to have invented podcasts. In his blog post, however, Navar argues that this was “almost a year before the start of podcasting.” We have wondered about this timeline, however. Using enclosures in RSS feeds was first publicly written about by Dave Winer in January 2001. Indeed, the system for downloading and distributing podcasts in Winer’s “Payloads for RSS” from 2001 looks quite similar to VoloMedia’s patent. When we spoke to Winer earlier today, he also pointed us to an early podcast by Chris Lydon from July 2003.The podcasting movement only really picked up steam in 2004, when moving downloaded files to iPods (which were also just coming of age) and other MP3 players became a lot easier thanks to numerous developers who wrote the first podcast clients. Looking at the patent, it quickly becomes clear that VoloMedia laid out the fundamentals of podcasting in great detail, including how to synchronize content between mobile devices and PCs. Navar argues that in November 2003, it wasn’t obvious that users would start to download episodic content. Given that Dave Winer first met with Adam Curry to discuss the concept in December 2000, however, we really have to wonder if this claim would hold up under greater scrutiny. We asked VoloMedia for a statement and will update this post once we hear back from them.More to ComeFor VoloMedia, which just switched gears towards a stronger focus on serving ads after it fired its sales team, this patent obviously comes at a good time. With some luck, the company will either be bought by another podcasting company interested in the company’s intellectual property (and Navar says that more patents are in the pipeline), or it will receive a nice influx of cash based on licensing deals with other companies in the podcasting business.

R-10 Vacuum-Insulated Glazing

first_imgFor twenty years or so, companies like Pilkington (Spacia) have been cranking out R-5ish (center-of-glass) vacuum-insulated glazing (VIG). The attraction of glazing units with a very thin profile, relatively low weight, and a high level of performance is strong, particularly for retrofit applications. But it sure seems as though we have been promised commercially available VIG with double that thermal performance for more than 10 years now. (See Images #1 and #2 in the Gallery, as well as this 2009 blog post by Alex Wilson.) The technological challenges for this level of performance have been significant, and so have costs. My good friend and colleague, Charlie Curcija — senior researcher in the glazing program at Lawrence Berkeley National Lab — is the guy I always go to for the latest and greatest news on high performance glazing. He says we very well could be there:RELATED ARTICLESVacuum-Insulated Windows‘Superwindows’ to the Rescue?Report from the International Builders’ ShowDoes Vacuum Insulation Make Sense? “The breakthroughs required for R-10+ VIG were in three areas: One, producing uniformly flat tempered glass (this is important for pillars to stay where they are supposed to); Two, having temperable low-e (Guardian was one of first companies, if not the first to develop temperable low-e); and Three, developing a low-temperature edge sealing process, so that glass does not de-temper.” According to Curcija, who recently returned from Asia, there are about seven or so Chinese companies that are producing VIG in the R-10+ range (center-of-glass) and just one being produced in the U.S. (by Michigan-based Guardian Glass). Guardian just did a big press event at an AIA conference for their two commercially available VIG products. And then there is Florida-based VIG Technologies, a company that uses LandGlass VIG from China. So, we’re are all set and just need to talk about pricing, right? Are the products even available? Not so fast; both Guardian and VIG Technologies are still very tight-mouthed about the major U.S. window manufacturers they claim to be working with. Apparently, you can’t order product from either of these VIG producers or any window manufacturers to date. There are real VIG installations in the U.S.: VIG Technologies has units installed at Viracon headquarters in Minnesota (Viracon is the largest glazing manufacturer in the U.S.) and Guardian has some of their units installed as retrofits at Eastern Michigan University (see Images #3 and #4 in the Gallery). By all reports, these units are performing really well. Curcija observed the Viracon units on a cold winter day and said that the units looked great and the thermal comfort near the units was impressive. Robert Densic, Eastern Michigan University’s manager for planning and design, is working on some initial Guardian Glass installations as a proof-of-concept project for much broader applications of  VIG products across the campus. So, what is the hold up? A lack of industrial capacity One trusted window industry source told me this: it’s really hard to focus on and marshal resources for new high-performance glazing when the industry is as stoked as it is right now. Charlie Boyer, vice president of research & development for Viracon, backed that up. He said, “We are very interested in this technology but we simply don’t have the capacity right now and are not quite ready to make the very substantial investment required to set up a whole new facility for VIG.” Additionally, when I asked Guardian Glass some very pointed questions about commercialization, one of their written responses was: “The Guardian Vacuum IG team is focused on multiple industries, with commercial refrigeration leading the way. We have partnered with Anthony International, the leader in the refrigeration door industry.” Huh? Refrigerator doors? Another trusted industry source told me this: no one in the window/glazing industry has seen any third-party certified laboratory testing of the new VIG product using the industry standard, ASTM E2190, “Standard Specification for Insulating Glass Unit Performance and Evaluation.” This testing includes temperature extremes and accelerated aging/weathering testing.  (For more information on this standard, including descriptions of specific tests, see “Certification and Testing for Insulated Class units.”) A new standard If you lose the vacuum seal on these IGUs, the thermal performance does not fade — it crashes. There is a new standard being developed specifically for stress-testing VIG:  ISO/DIS 19916-1, “Glass in building—vacuum insulating glass – Part 1: Basic specification of products and evaluation methods for thermal and sound insulating performance.” Rob Tenent of the National Renewable Energy Lab (NREL) is gearing up for a project looking into the specific stress testing needs of VIG, working with Lawrence Berkeley National Labs (LBNL). Frankly, no one seems to know, or is willing to state, whether these new VIGs require stress testing tuned to their performance or properties. But that is exactly what this NREL/LBNL project is about. The refrigerator door market All of this concern could be one of the reasons that Guardian Glass is focusing on the refrigerator door market: While the temperature difference from inside to outside the refrigeration units is large, it represents a fairly steady delta-T. I am not saying that the VIG seals or long-term performance are suspect; I am saying that no one seems to know or be willing to talk openly on this issue, and it is really important. How much do these IGUs cost? What about costs? Not surprisingly, it’s impossible to get this sort of information from VIG Technologies or Guardian Glass at this point. But here is what Curcija learned while in Asia: Chinese VIG producers gave manufacturing costs of up to 1,500 Yuan/m2. Using $1 = 6.7 yuan and roughly 10 sf/m2, that equates to $22 per square foot. In the U.S., it’s typical to multiply manufacturing cost by 3 to get the consumer price (glazing installed in a window), which would mean $66/s.f. for consumer buying windows with VIG. Note that this price does not include any tariffs. For comparison purposes, standard double-glazed IGU in the U.S. is about $10/s.f. retail, with Passive House triple-glazed windows in the range of $30 – $70/s.f. New VIG from Guardian Glass (made in the U.S.) and VIG Technologies (made in China) are poised to make serious inroads into the high-performance glazing market in the U.S. They are not cheap, but if their long-term thermal performance can be verified, they may very well be worth the cost.   In addition to acting as GBA’s technical director, Peter Yost is the Vice President for Technical Services at BuildingGreen in Brattleboro, Vermont.
