first_imgLooking down, there is nothing for 30 feet and then the leafy floor of the Potsdam forest in Germany. My head is red from exhaustion. When I look at my hands, they are shaking. I try to write my geocaching username in the small logbook, but the letters are scrawly. “At least I did not forget the pen down there,” I think to myself.Do not forget a pen, before going up!“Now you have to come down” Ralf (Geocaching username: DeepdiverBerlin) calls from below. Ralf’s specialty are T5 caches. Geocaches with a terrain 5 rating require specialized equipment. That can be a boat, a vehicle with 4 wheel drive, or in this case, climbing equipment. Ralf brought his experienced friends Karsten (Karsten & Co), Gisela (water&sun) and Michael (Vista-Freund) to show me the ropes (pun intended) when it comes to finding geocaches hidden high up in trees.“Pull!”, they yell and laugh and I carefully remove my hand ascender from the rope and pull the trigger of my descender to slowly let the rope slip through. And I come down, a lot quicker than it took me to climb up.A little shaky I land back on the soft forest floor. I feel thrilled, excited, and very accomplished, but before too long, we pack up our climbing gear and go to the next geocache that is placed high up in a tree.We tackle 5 trees that day. Each with a different shape, height and technique. At one geocache location, we have to build a so called “ropeway” between two trees to get to a far out branch too thin to support anyone’s weight. Another time we have to pull the climber to the geocache from the ground. Tree climbing seems to be a great combination of physical and cerebral strength, as we often ponder over the best technique before getting the ropes in the trees and making our ways up to the geocaches.I am glad to be able to learn from experienced climbers. Gisela is close to her 1000th geocache, she got while climbing a tree. “We thought, these kind of geocaches are for other people. That we will never get them,” says Michael, “But then a friend of ours took us and taught us how to do it and now we are hooked!” I can understand why. The physical exertion, making it way high into the crown of a tree is so adventurous, but being guided with experience and secured with good climbing gear, I feel very safe.Gisela and Michael also took tree climbing classes to further their knowledge about tree climbing and also about tree types. It can be dangerous for inexperienced geocachers to climb a tree, because they don’t know enough about the sturdiness of different tree types, or cannot distinguish sick or dead trees from sturdy, healthy ones.“This is my kind of adventure,” I think in the evening at a local geocaching event in Berlin. My legs are hurting, I can barely keep my eyes open, but I am happy and proud to have added five T5s to my geocaching statistics today. And I am looking forward to the next tree, and to my next geocaching adventure!What geocaching experience made you feel proud and accomplished? Let us know in the comments below!

first_img GREEN PRODUCT GUIDE First, the flooring choicesAbove-floor radiant tubing can be installed in aluminized floor panels such as Quik Trak and then covered with finished flooring. Alternately, the tubing can be covered with a layer of concrete, either conventional concrete if the floor framing is designed for the weight, or a lightweight gypsum concrete. RELATED ARTICLES Minisplits may mean the end for ground-source systemsKevin Dickson wonders whether the “impressive” performance of the Mitsubishi minisplit, particularly when heating loads are very low, “should make everyone think twice about ever doing a ground source heat pump.”Ground-source heat pumps have been considered a good cold-climate option because they operate more efficiently than conventional air-source heat pumps. But they are very expensive to install, and some critics think their efficiency numbers are often overstated.“Marc Rosenbaum has predicted the withering away of GSHPs as a residential option — because the Asian ductless minisplits are getting so good,” Holladay says.“Martin, good point about the perhaps waning of the GSHP trend,” writes James Morgan. “I was never happy about the extent to which it has been promoted through tax credits.” All About Radiant FloorsRadiant-Floor HeatingGoodbye Radiant FloorGreen Heating OptionsHeat DistributionCooling OptionsHeating a Tight, Well-Insulated House Will a water heater work?No matter what kind of flooring ultimately covers the tubing, a more fundamental question is whether a water heater will produce enough hot water for the radiant distribution system.“You might be able to heat with a water heater,” Meiland adds, “but the real question is, how many BTUs do you need for space heating and how many for water heating? I tend to like boilers a lot more than water heaters for radiant, but ultimately what you need is someone highly skilled to design and install the system, and should probably ask their opinion.“Anyway,” Meiland says, “it all starts with a heat loss calc.”Depending on the heating load, a conventional water heater might struggle to handle both heating and domestic hot water needs. Harold Turner points Smith toward the high-efficiency Phoenix water heaters made by Heat Transfer.Turner says the water heaters have a peak output of 166,000 BTU and come with an optional solar heat exchanger should Smith want to add thermal solar panels down the road.Damon Lane suggests Smith contact a company called Radiantec, which designs radiant floor systems and recommends a Polaris, another high-efficiency water heater.Radiantec advocates an “open-direct” system in which domestic hot water is circulated directly through radiant floor tubing.“They can help you with the installation details,” Lane says, “and I would guess the limited cooling their open direct system offers by pushing your domestic cold water through your floor in summer will be enough for your house.” Lucas refers to this second option as an “over-pour,” and says some contractors have told him not to pursue it because the house is so tight. “Others say I would be wasting my money not doing it,” he adds.But David Meiland thinks Smith is talking apples and oranges: “I don’t see what an ‘over-pour’ has to do with the house being extremely tight,” Meiland says. “You are either going to install tubing using a product like Quik Trak, or you’re going to pour gyp or lightweight over it. In my opinion you ought to review your choices of floor coverings and see which way that pushes you. I personally like gyp but it’s harder or impossible to install some types of flooring over it. “ What about a ductless minisplit?Smith does not have gas service, but he reveals that his electric rates are currently about 6 1/2 cents per kWh, and that prompts an entirely different suggestion.“Your electricity is very cheap,” GBA senior editor Martin Holladay says. “I think that a ductless minisplit system would make sense for you, providing both heating and cooling at a much lower energy cost than propane-fired hydronic heat.”Ductless minisplits are a type of air-to-air heat pump in which a single outdoor unit serves a number of air handlers in individual rooms, without the need for installing a conventional duct system. Although traditional air-source heat pumps resort to electrical resistance heat when outdoor temperatures drop into the 40s, newer versions are much more efficient in cold weather.“A good option with your cheap electric rates would be a ductless minisplit, as Martin mentioned,” says Bob Alsop, “which would take care of AC as well as heat during the ‘marginal’ seasons (spring, fall). An electric boiler would take care of the radiant (winter) as well as domestic. Ductless minis are great, but be aware that they are limited when it comes to very cold winter temps. At least here in Vermont.”Not so, Holladay adds, pointing out that Mitsubishi Electric makes a minisplit that performs at -13°F “without using any electric resistance elements.”NLehto seconds Holladay’s suggestion. He writes that he has a 1-ton Mitsubishi minisplit in his 1,900-sq. ft home in Connecticut. “As of January 12th I’ve spent $170 heating it this season and that’s with Connecticut’s ridiculously high electricity rates,” NLehto writes. “The coldest outdoor temp I’ve experienced with it so far is -4°F, and it had no problem keeping the house at 70°F.”Robert Riversong argues that at sub-zero temperatures, the heat output of these units is “negligible,” but Holladay adds that Mitsubishi’s Mr. Slim Hyper Heat unit, with a nominal output rating of 38,000 Btu at 47°F, will still produce 30,000 Btu at -13°F — a reduction in heating capacity of only 21%.Yes, says Riversong, but efficiency suffers. “According to the spec sheet, the [Coefficient of Performance] at 47° is 3.3, at 17° it’s 1.85 and at 5° it’s 1.65. At -13°, I suspect it operates with no more efficiency than resistance heat – COP = 1.“So, you’re correct that this unit can maintain output at very cold temperatures, but it trades output for efficiency, which makes it inappropriate for very cold climates with little to no AC requirement. “Holladay disagreed with Riversong, noting that “a COP of 1.65 at 5°F is excellent.” Lukas Smith, a framer by trade, is building a 3,100-sq. ft. house in southern Ontario and plans to install a radiant-floor system in the basement slab as well as the first and second floors. The house will be built with structural insulated panels (SIPs) and have R-values of 33 in the walls and 50 in the roof.With that as background, Smith poses three questions in his Q&A post: should he pour a layer of gypsum-concrete over the tubing; can he run the system from a hot water heater instead of a boiler; and what is the best way of providing air conditioning?The discussion is the subject of this week’s Q&A Spotlight. Heat Pumps Our expert’s opinionWe asked GBA technical director Peter Yost for his thoughts. Here is his response:Air-tightness and radiant floor heat “base”: I see no connection between radiant floor heating distribution systems and air-tightness, unless this is an oblique reference or connection to the fact that radiant floor distribution, as a non-forced air distribution system, will require a stand-alone ducting for mechanical ventilation system in airtight homes?Using a water heater to supply radiant floor space and domestic water heating: Absolutely go with a high efficiency tank water heater, such as the Polaris or Phoenix, particularly in a climate like Ontario, CA. And heat calcs are a must.Real care is required to use radiant floor distribution systems for space cooling because you can’t push very many Btus around for cooling without thermal comfort and condensation issues on the floor. And I would bet that in Ontario the times you need space cooling are the very times you might have higher relative humidity, further constraining the use of radiant floor distribution for space cooling.Here in our Vermont home in the summer, we only run refrigerant-based cooling for a handful of days in the summer, relying on ceiling and whole-house fans and night-time flushing almost all of the summer. And if we get control of our late afternoon solar gain from the west this year, we won’t need any refrigerant-based cooling at all. I bet in Ontario, the right design and shading strategies can mean no refrigerant-based cooling as well, or at least just one well-placed ductless mini-split.The main thing here is what he thinks of the thermal comfort of each system. It’s hard to beat the feel and quiet of radiant heat in comparison to the potential noise and cold-blow issues of heat pump-based forced air systems.last_img read more

first_imgOn its way out the door, the Obama Administration greenlit 10 sites across the United States that will become “proving grounds” for autonomous cars, including one in Michigan and two in California.The Department of Transport (DoT) announced its picks one day before Obama left office, one of the hundreds of pieces of legislation passed in the last days of the administration.See Also: Google’s Waymo self-driving cars kept offline to avoid hackersWillow Run, an old B-24 bomber plant in Michigan, will be the flagship proving ground. The American Center for Mobility is converting the 311-acre site to test autonomous cars from Ford, General Motors, and Hyundai.The state of Michigan is bankrolling the effort, to the tune of $80 million, in the hope of bringing automotive jobs back to Detroit. It expects the site to pay for itself after a while, through federal grants and possible payments to test vehicles.Michigan has already pushed through meaningful legislation to legalize self-driving cars in the state, and some auto and tech firms have moved their autonomous operations into Detroit.What will Trump do?A decommissioned Naval base in Concord, California, will also be redeveloped for autonomous vehicle tests. Other sites in Arizona and Washington were chosen, but the DoT have not said how much will be spent to convert the sites for autonomous testing.“The designated proving grounds will collectively form a community of practice around safe testing and deployment,” said ex-U.S. Transportation Secretary Anthony Foxx in a statement. “This group will openly share best practices for the safe conduct of testing.”The Trump Administration has not said anything about the onset of autonomous cars, but considering his commitment to bringing jobs back to U.S. citizens, the administration could most likely be against any further development of autonomous technology. That could be an issue for the auto and tech firms that have spent millions preparing for the self-driving revolution.
