    Foundation heat loss and insulation.

    + brings on mold/mildew air quality issues in humid summer climates. Also something to account for there. Less need for a dehumifier with warmer foundations in the summer...

    Jotul 8?? Can anyone shed some light on that stove?

    Ahh ok yours doesn't have the true "spin" draft at the bottom (on mine that round thing was an actual draft control, with handle and 2 semicircular slots for admitting primary air on the top & secondary air underneath). It's just controlled by the upper right. Might still be a non-catalytic...

    Jotul 8?? Can anyone shed some light on that stove?

    My old original Jotul 8 didn't have a draft slider in the upper right fwiw. I thought that was a feature of catalyst versions? Maybe the old owner took out the catalyst, who knows. The top lid should lift right off if I'm not mistaken - it's held in place by its own weight and a large...

    Have we reached a tipping point?

    It's like tuning your car's wheel alignment out of spec a little more each year. No you can't blame that near-fatal accident on bad alignment, but I wonder if those tires would have had better tread and traction and wouldn't have skidded across a lane if you'd have corrected the problem instead...

    Have we reached a tipping point?

    A bit of both. PG&E probably could have gotten away with a few more years or maybe a decade of mismanagement of their infrastructure & lack of trimming had global warming not set in. Global warming/climate change just caught them sooner with their pants down. It's not like climate change can...

    Have we reached a tipping point?

    Atmospheric carbon isotope ratios, which have been shifting rapidly since ~1850. http://www.realclimate.org/index.php/archives/2004/12/how-do-we-know-that-recent-cosub2sub-increases-are-due-to-human-activities-updated/ It's one of the damning "fingerprints" at the scene of the crime.

    Wow. More positive feedback in the climate system--all that peat moss decomposing accelerates the process faster.

    EV subsidies

    I don't know why the oil industry isn't chomping at the bit to jump into this- https://thedriven.io/2018/12/14/diesel-charge-evs-remote-locations-greener-than-you-think/ The oil industry is in a fantastic position to capitalize on the fact that DC Fast Charging stations have yet to reach the...

    Have we reached a tipping point?

    The basic problem over all is, how do we retool modern society into one that uses largely non-GHG emitting energy sources, and can grow its energy usage commensurate with our desire to improve our lifestyle, while allowing those less endowed to improve their lifestyle as well. Burning things is...

    Electric Lawn Tractors

    Looked into this briefly the past week (looking at a 5 acre residence tho probably not going for it). Was also underwhelmed with what's out there.

    New Solar Roof System

    Yep from what I heard on a podcast ( https://theamphour.com/443-an-interview-with-jp-norair/ btw) the high temperature features are validated already, but I don't know what that means. I do know that with GaN FETs for the inverter and such, they can probably use smaller capacitors (& inductors)...

    New Solar Roof System

    Startup I heard about in a podcast this morn- https://www.solpad.com/ Main contribution is the use of GaN (gallium-nitride) transistors for their microinverters to improve power handling vs. heat and size characteristics, and batteries spec'd to withstand roof temps so the battery...

    Osage orange listed as a cord for $150

    FYI I don't know if there's any left but someone on MD-31 right at Libertytown has had unsplit pine logs free for the taking near the roadside for a while. He fell a hedge of pine trees and I think I saw the last of them piled up last week coming home from work. Might help light those...

    Bought a 2019 Bolt

    L2 charging at home is really important IMO and really changes your perspective on EV ownership - fully charged in hours and effective preheating of the car. Keep the battery conditioned overnight too. I jury rigged an adjustable juicebox w/ the right adapter to plug into my 240V dryer outlet...

    2018 emissions surged

    I have been a broken record on this subject as of late (spent a lot of time last year studying it) but I just want to interject the possibilities that may be coming down the line by 2030 for Nuclear Fission-based techs- 1. Small Modular Reactors lighting up remote sites, reducing the need to...

    Rick Perry (remember him) does good

    I am somewhat pleased with Perry's performance so far. As with all Trump appointees I assumed the worst. His DOE efforts on nuclear energy are noteworthy (opened TREAT already after decades-long hiatus, restarted Pu238 production and committed to HALEU). Hopefully this side of the DOE bears...

    On the other hand, there is cordwood construction- https://cordwoodconstruction.org/ (Richard Flatau posts a lot on the facebook group Talking Natural Homes about this stuff)

    Power or energy Rant

    Where are we with ultracap tech these days? Is this based on what I've seen on smaller scale "supercapacitors" where they store high capacitance but there are stiff voltage limits (iirc they work by having super thin dielectrics wrapped tight for enormous surface area but low breakdown voltage)

    CO2 to Fuel

    I've also read part of the problem at Hanford is we have solutions but nobody wants to implement them (as it would stop the funding train for the site if the job were "done") https://atomicinsights.com/atomic-show-201-better-way-to-clean-up-hanford-tanks/ I would also suggest that it is...

    CO2 to Fuel

    Depends on where they go but pretty much. Local soil should not be oxidizing. Personally I'd prefer we reprocess the stuff and extract the useful contents. Only 3% or less of the stuff is actually nasty materials and there is still a goldmine of isotopes and rare materials in that portion...

    CO2 to Fuel

    Spent rods live for 5 years in a water pool while the nastiest of radionuclides decay, then they are entombed in dry casks made of steel and concrete where they sit above ground. I read a quote in a book where all of the world's civilian nuclear spent fuel for the past 60 years would fill a bit...

    Big changes are happening in transportation

    I am eager to see what electrification accomplishes for the "fuel" question with SUVs and trucks. I know they will use more but I wonder how much more on average. I am thinking the crossover BEV or PHEV will be the new sedan.

    CO2 to Fuel

    You are right IMO about the absurdity of using expensive renewable energy for this. Nuclear is a better fit.

    CO2 to Fuel

    Put it a different way... The academics studying the economics of climate change (JesseJenkins on twitter has been my main source/feedpoint of info on this) seem to agree that most efficient way to curb emissions and mitigate climate change is to enact a Carbon Tax. Price the externalities of...

    CO2 to Fuel

    For those of us actually concerned with anthropogenic (largely from CO2 emission) climate change, the value here is being able to produce fuels compatible with current equipment WITHOUT digging more carbon out of the ground, the source of the problem we're trying to solve. This is one of those...

    Big changes are happening in transportation

    Level 2 stations aren't too bad price-wise but IIRC L3 DC fast chargers are a different breed. Capital costs upfront won't pay themselves for many many years until EVs are more popular and the charging fees can bring in more revenue. Until then I see charger adoption in public following the...

    You are probably right about that, I read motorcycle engine on a forum one time but they were probably speculating too.

    Big changes are happening in transportation

    Yw Pretty much. The BMW i3 w/ Rex is slightly different in that it's an EV with a 25kW motorcycle engine generator for range extending (still considered a plug-in-hybrid but a "series" PHEV vs others that are "parallel" hybrids) but most hybrids work that way. Look up Weber Auto on youtube...
