AIT, Golden, Jeff's Birthday, Brewfest, and points in between 
Monday, October 10, 2016, 07:24 PM - Work, Weekend Fun, Week activities
Posted by Administrator
Here's a bunch of random things:

AIT Visit. I hosted a couple colleagues from the Austrian Institute of Technology in the lab to work on hardware-in-the-loop testing of a smart inverter. It was great to have Roland visit, as the two of us have shared some fun times in Japan, India, and France.




NREL meetings. I had a bunch of GMLC meetings in Golden, which sounds boring--and it was--but Spencer lives 5 minutes from NREL and he had a spare mountain bike! We rode over the mesa to dinner and had a couple local brews along the way. It was great to ride again with my ex-housemate while on work travel.

Flying. I went paragliding again - I took my 30th flight and finally got my P-2 rating!



Bike and Brew. Jeff had a bike pub ride for his birthday. He had a good time.



AMRC Brewfest. I survived 12 hours of volunteering at the AMRC Brewfest. Love that event because I see so many of my friends.



UNM talk. Thursday, I gave a talk at UNM on my solar research. "The Science & Society Distinguished The Public Talks are co-sponsored by the Albuquerque Section of the Institute of Electrical & Electronic Engineers (IEEE) and its Life Members Affinity Group, Sigma Xi (the Scientific Research Society), the UNM Department of Physics & Astronomy, and the UNM Division of Continuing Education."

AMRC mission. The next weekend I responded to a stuck climber at Diablo Canyon - but the rest of the team beat me there and got them free before I could be fielded.

Tennis. Jess and I played about 20 minutes of tennis before getting completely soaked in a monsoon deluge.

Taos Scavenger Hunt, Work Travel, and Spring Paragliding 
Sunday, March 20, 2016, 01:41 PM - Work, Trips, Weekend Fun
Posted by Administrator
I talked Jason into letting me borrow his Aliner camper indefinitely but after getting ahold of it, there was so much rat damage it seemed a little overwhelming. I spent 8 hours on Thursday and Friday cleaning out the rat poop and mopping up the rat urine stains. I washed the curtains, oiled the jacks and hitch, bought a new battery and wired it up with a switch on the hydrogen gas capturing box, and then spent 3 trips to autozone to get the proper 7 blade to 4 pin trainer adapter to have brakes and turn signals with the outback. It was a lot of effort, but in the end, the smell was tolerable and I rolled out of the driveway before it was completely dark. Driving that 2000 lb box up the mountains was a stressful experience, but the 2.5 L outback managed well and it held 70 mph up La Bajada hill at 4200 rpm. In TSV, Jason helped me park the Aliner in the middle lot and we turned in after getting the heater working and messing with the battery charger for an hour.




The following morning Jason and I formed "Team Happy Dog Lips" and competed in the New Belgium Scavenger hunt. We spent a couple runs at the beginning trying to find a paddle on a run with mythological connections (Castor, Pollux?) and a German gentle giant who helped the poor (St. B?). Well, it turned out to be on Rubezahl (!), so we wasted a good hour doing some extreme scavenging. Then we took one on Reforma to catch the chicken, and one on Trescow with Victor, before coming to our senses and skiing to the Bav. Luckily everyone was already there! With the help of Briana, Josiah, Spencer, Kat, and others, we didn't found the tutus, Yeti, Park Ranger, and a bunch of other wild things around the mountain. Yay for crowdsourcing! Toward the end of the day, Josiah got a crew together to ski a topless (well, shirtless for the ladies) run down Al's and we got a loads of shout outs from everyone on the lift. Gotta say that was one of the funniest runs of the year ;) Then it was on to the party at the New Belgium tents, RVs, Tim's, St. B, and points in between.





That night, Taos got 3" of snow, but the wind loaded up some places to 6-8". No one else got up early but I nabbed fresh tracks on Al's, Inferno, Walkeries (3 times in a row), and Wild West before anyone joined me. Some spots were nice and fluffy, but others were windswept and crunchy; the variable conditions were actually quite challenging for the skinnier Nordica Top Fuels and I wrecked a couple times. Sadly I didn't have anyone there for make fun of me.

Monday I flew to San Francisco for the SunSpec meeting. It was good to see all my colleagues, and continue the good work that I'm doing with their trade alliance. I met Timothy and his wife for dinner at Mikkeller's and sampled some of the SF beers. IPAs were good, but I'm still struggling to find the appeal of sours. From there, I flew to DC for a microgrid workshop. Abe's trying to create a massive testing lab consortium and I seem to be getting roped in as one of the leaders. Fortunately, I found time to visit Pearl and Paul and their son, Lee, on Thursday night. As some of my favorite people from my NREL/Boulder formative years, it's so good to reconnect and see how life has taken people in different directions. I got to read Lee's bedtime story. It's nice to have friends across the country.






Returning from DC late on Friday night, I picked up some sort of cold-like illness. I was achy, had chills, no appetite, a headache, and generally just wanted to sleep the rest of the weekend. I had hot and cold episodes all night but recovered fairly well on Saturday while I ran errands and worked through my list of household chores. Saturday morning, I still wasn't 100%, but I got out to Rio Puerco to take the first paragliding flight of the day the Chuck, Jim, Rich, Max, Spencer, and 3 tandem fliers. I only got 1500 AGL, but the air was smooth in the early morning, so I didn't complain much.

Solar Power International 2012 
Sunday, September 16, 2012, 09:40 AM - Work

Headed off to SPI in Orlando this week. Had a great time seeing the Blue Man Group at Universal Studios and then partying at the Ice Bar (a 20 degree room constructed of ice inside a club in Florida during the summer). Doesn't really ring with the environmentalist in me, but trade shows are definitely funner than technical conferences.





President Bill Clinton was the keynote speaker at the conference. He gave a great speech and encouraged the solar industry to reach the tipping point to get solar installations accelerating.

Gave an update on the National Electrical Code 690.11 at the Solar ABCs Stakeholders meeting Friday to about 125 people. It seemed to go well and I made some good contacts.

Biking to work

After a very long day at work, it's horrible to be confronted with a 20 mph head wind and thick, suffocating smoke. AZ is on fire and Albuquerque gets screwed.
