RE: Sad state of national parks and forests - II

And while it may not be nearly enough, look at what the other party has actually given from their own pockets, from Obama, to SlowJoe to Harris, NONE give as much as Trump did. You may not like him, but from a personal standpoint, he has done/donated more than any others for the last 30 years. You’ve got things entirely backwards. The truth

RE: The importance of a TPMS Tire Pressure Monitoring System

I have never lost a tire from a slow leak. Always cord separation or total failure. I had belt separation on an inner dual and got warning on the TST TPMS. The warning came in the form of the inner dual pressure starting to increase as the tire diameter started to increase and unloaded the outside tire. Fortunately we were 200 yards from a tire store when the tire started to disintegrate. Limped over at 5 mph. I am on my second set of much tougher all steel cased commercial tires as a result. The TPMS allows comparing the tires in real-time while driving and learn to read the tire characteristics of each position: 1) Slightly increased pressure of inner vs outer tire. 2) Heating from tailpipe. 3) Heating from sun shining on one side vs other 4) Typical pressure rise 5) Pressure rise due to hot asphalt highways in summer 6) Much hotter running front tires due to engine proximity and sensors on short stems close to wheels

RE: Sad state of national parks and forests - II

When Donald Trump was President, he donated his annual salary to the Nat'l Park Service. Not a lot of money to the NPS total budget, but nice gesture showing he was aware of their problems. Indeed a nice gesture. And he added some more of his own from his personal wealth to round it off to $100,00 since it's just $78,000. I'm not one to tell anyone what to do with their own money, but I would have preferred his administration did not cut $2 billion out of the national parks budget while giving big business $1 trillon in tax cuts that promised economic boom that did not happen. And a bit of irony, it's when the NPS is asking for funds just to address these maintenance backlogs. 3 card monte......wish people would learn. $750.00, that's seven hundred and fifty dollars, in federal taxes for a YEAR. Yes and presidential salary is $400,000 not $78,000. Plus $50,000 for expenses.

RE: Generators!! Yes YOU!

The Victron 15A looks good with separate battery and load outputs. Great for using the unused panel output once the batteries are getting charged up. I'm trying to picture in my head how this would work... I thought most RV setups had the 'loads' and the 'battery' all tied together (over simplified, I realize), whether via terminal connections, bus bars, etc. Or would this be for where there is a 'house' battery bank, and a 'starter' (vehicle) battery? Thanks, Monte I have looked around a bit so here’s my understanding. The load output control is programmable based on the solar and battery state. So yes. charge the chassis battery when the house batteries are full and the solar is active. Or control a relay switching a load attached to the battery.

RE: Generators!! Yes YOU!

Ramble, your portable solar setup is real close to what I would/will add to our 2005 24ft. E450 Class C! I'll probably never use a portable with it's controller at the panel. I'd use an MPPT controller at the batteries permanently so that voltage loss between the panel and the coach batteries will be minimum at all times. The V10 idles so quietly, charges coach batteries so fast via the alternator, and only consumes about 0.7 gal of fuel per hour when idling ... that I've been doing that a lot lately and wondering if I even want to add any solar. Our camping style is usually only short stays at any one place, so the batteries get topped up when driving between locations. pnichols - We are totally satisfied with our setup for our low power daily needs. We were at a cold high Cascade lake in the trees with the panels 160’ away on the lakeshore in the early morning sun producing 9.2A with controller at the battery. This was enough to run our furnace and still charge the battery. With a 40’ cable it produces 11.2A. You will still have the 2 volt drop with the controller at the battery except the drop is off the higher panel voltage. MPPT would be great however we don’t need the additional 20% power. The Victron 15A looks good with separate battery and load outputs. Great for using the unused panel output once the batteries are getting charged up. The spec on the controller not starting until panel voltage is battery voltage + 5 volts may be an issue with this panel setup. The 2 panels in the solar suitcase are wired in parallel not serial. V10 backup is great for gen. The control board on the auto transfer switch failed one time while we were at Mt. Rainier so gen output would not switch in so used the V10 to charge. Did not bring the solar that time as we assumed the tree canopy would too shading. Turns out that there was sun available but would need more line.

RE: Generators!! Yes YOU!

Ramble, that's a great setup!! Two quick questions (not to hijack the thread). First, which brand of suitcase did you get? Second, with a 160 foot cable run, do you experience any significant voltage drop? And (to bring it back on topic after my borderline hijack), if I had a setup like yours, I would be more willing to leave my generator home!! ;) Profdant139 - I have a Renogy 200 watt. Open it is 36” high x 52” long. They have a lighter taller narrower one but it won’t fit in storage. I have a 2nd controller to locate near the batteries that I use for the 160’ run case since the 0.2 ohm estimated wire resistance implies a 2 volt drop. Most of the time I just use 40’ with the built in controller. I like to keep the setup flexible to use to charge the chassis battery or other batteries. Cold camping we run our gen before 10pm and crank the heat up so the furnace doesn’t kick in for a few hours.

RE: Generators!! Yes YOU!

80% of our camping is dry camping. With 200 watt suitcase solar and 160’ of 8 AWG solar cable in 3 segments we park in the shade and put the solar in the sun. Some days we don’t run the generator at all. Other days we run it for coffee, microwave.

RE: Tranny fluid change

I’ve got the Ford TorqShift with the external bypass filter in a housing and it’s quite frozen. Couldn’t crack it loose with a 1/2” rachet and didn’t want to break something. Thinking about trying to use a filter wrench on the filter housing along with the rachet on the end nut. Any tips?

RE: F150 Lightening

A hydrogen fueled truck would make a lot more sense. The battery trucks will require an hour charging for every 150-200 miles of driving. What is needed is fueling stations. Take a look at this hydrogen SUV. 380 mile range, 4000 lb. towing, and 5 minute refueling: https://www.hyundaiusa.com/us/en/vehicles/nexo/compare-specs The Nexo is nice. But holy carp, talk about expensive fuel. And presently very hard to find. Still, nice little SUV. Cheaper than diesel green hydrogen is on the way. It takes around 58 kWh to generate a kg of hydrogen and with power purchase agreements dropping to 2 cents/kWh as in the following link the raw generation costs will drop. https://emp.lbl.gov/pv-ppa-prices

RE: One Great Big EV Thread

The concept has been brought out of the lab. They need 1.8 billion euros of funding. https://v-er.com/wp-content/uploads/2021/01/PFS-Presentation-Vulcan-Energy.pdf

RE: One Great Big EV Thread

Commercial production feasibility of geothermal lithium has not been demonstrated. “ Although a lithium extraction technology may have been demonstrated in the lab, showing that it can run economically at a large geothermal facility remains to be proven.” https://newscenter.lbl.gov/2020/08/05/geothermal-brines-could-propel-californias-green-economy/

RE: One Great Big EV Thread

I was admonished for saying lithium can be mined in a more environmental friendly way (geothermal lithium) because that is not how it’s done today. Just like hydrogen can/will be clearer in the future, lithium can/will be cleaner in the future. Right now the cleanest hydrogen is dependent upon the power generation mix used in water electrolysis. What is the actual amount of geothermal lithium reserves available at how many sites? There will be enormous demand for lithium and lithium is not significantly available in the earth with an upper continental crust concentration of 0.0035% and a mantle concentration of 0.00015%. The only lithium extraction methods currently in use are brine concentration and hard rock mining. No other methods such as geothermal or extraction from clays is currently in production use. Example: The largest known deposit in the US at Thacker Pass in Nevada has a concentration of just 0.33% in lithium clays. Extraction will require the production of 5,800 tons of sulfuric acid per day.

RE: One Great Big EV Thread

What percentage of hydrogen fuel is currently being made by 100% renewables, 1%, 4%? That is how much you can reduce the carbon footprint of hydrogen production. Gray hydrogen is the present. Green hydrogen is the future. Countries around the world are going to use green hydrogen to decarbonize transportation, electricity production, and heavy industry. 200+ projects worth $300+ billion: https://hydrogencouncil.com/en/hydrogen-deployment-accelerating-with-more-than-300-billion-in-project-pipeline/ Here’s a US project to drive the cost of hydrogen below the cost of diesel by 2030: https://www.msn.com/en-us/weather/topstories/ladwp-joins-at-scale-green-hydrogen-initiative-hydeal-la/ar-BB1gPBwu

RE: One Great Big EV Thread

Estimating The Carbon Footprint Of Hydrogen Production This converts to 0.28 kg of carbon dioxide emissions associated with one kilowatt-hour of hydrogen production. Of course, that is just the carbon footprint of hydrogen production. To use the hydrogen for power, it still must be compressed, transported, and either combusted or converted to electricity in a fuel cell. The fuel cells themselves must also be built, and there are carbon emissions associated with those construction processes. For perspective the Energy Information Administration lists the carbon footprint of electricity production from coal and natural gas as 1.0 kg/kWh and 0.42 kg/kWh, respectively. But that is for the actual conversion into power, and not just the energy content of the fuel. You are describing gray hydrogen which is made from fossil fuels. Green hydrogen is made from 100% renewable energy using electrolysis and has no carbon emissions.

RE: One Great Big EV Thread

I’ll wait for a 5 minute hydrogen fill in a nice hydrogen SUV. Batteries and cold will never work for me. I saw my first Tesla at a ski area this year. 4 backed in and plugged in at a building. Along with 300 non plugged in non BEV vehicles (week day). The ski areas will not be putting in hundreds of plug-in outlets and snow riders will not be waiting a half hour each to wait for a shared plug in outlet.

RE: One Great Big EV Thread

That's 200,000 km (which is equivalent to just over 124k miles). Yes, when the powergrid comprises of power generated exclusively from the top three clean sources: nuclear, wind and hydro, then BEVs will kick ass, as the breakeven will be almost instant (just under 30K miles for the XC40)...provided the car is driven frequently (which unfortunately for my wife, is not the case). So how many years will it take for the powergrids to have clean energy? As in here in the USA, nuclear is verboten. Gotta have water for hydro, and wind for wind.....and we know solar and geothermal are really 2 bit players in the power game. Solar has 8X the potential of wind. Scroll to page 20 of this NREL report: https://www.seia.org/sites/default/files/resources/NREL%20Renewable%20Resource%20in%20States%20Study.pdf Potential of renewables is >100X the annual electricity consumption of 4 TWh. So plenty for BEV charging and hydrogen production but need the infrastructure obviously. I haven’t run the numbers for TWh equivalent of all current annual oil and gas consumption.
