    Tesla Model 3 Parked in Our Garage

    The Bolt was the most fun and nicest car I ever owned. I miss it.

    EV Myths

    Randy, did I hear that The Great Cheeto was rolling back Ethanol subsidies? ** Insert broken clock analogy here **

    Good to hear that the Bolt is still getting some love next to its sexier sibling!

    Should I use my oil or electric water heater when burning wood

    With hybrids, it is easy/cheap to heat cold water, and takes progressively more electrical energy per BTU added as the water heats up. So using an oil as a pre-heater or tempering tank is not a good idea. Just run them separate.

    Wind power is passing coal in Texas so far this year

    The real issue with small versus big wind is that wind just blows faster and more steadily with altitude, and it just keeps increasing as you go up. In fact, the reductions in the cost of industrial wind have largely been the result of steadily larger/taller machines. This is why many...

    New roof!

    How many miles does the Mrs do in a day or a year Matt? Volts are cheap, are fun to drive (and sporty compared to many cars), and the gas backup removes any worries (300 miles on an 8 gallon tank). She might like the low noise, low jolt driving, my wife was hooked after a test drive. My '15...

    New roof!

    Clearly, Matt, you just need to buy an EV. You have already made your house really efficient and use NG that is presumably pretty cheap. If you can move 10,000 miles per year to electric, that will be about 3,000 kWh right there (assuming a cold climate and spirited driving). Plus your...

    A little quiz on climate change

    Well semipro don't feel bad. I own the book, read it last year, and got a 56%. ;em ;lol

    Buying an EV as a commuter vehicle - does it make sense?

    Indeed Spacebus. But having driven small ICE cars, I am saying something different. EV drivetrains just feel more luxe, more fun, more man-machine fusion, and are more pleasant (quieter, less smelly, less motion sickness inducing) across the board. So I have never really cared about finish...

    Buying an EV as a commuter vehicle - does it make sense?

    The Bolt would not be a problem for you in height or legroom, but it might feel a little narrow sideways. The volt would be a tad cramped IMO.

    Buying an EV as a commuter vehicle - does it make sense?

    Welp, I have had a gen 1 LEAF, a 2017 Bolt EV and now a 2015 Volt. :cool: They are all cars whose fit and finish feel cheap, but whose driving dynamics feel really nice/fun, not cheap at all. The Bolt was the best of the three, and the most expensive. I suspect Jim's Model 3 blows it away. :(

    Renewables pass coal in April

    That last article nailed it. Exponential growth in renewables, but whose annual additions in energy are still smaller than the annual increase in global demand. But they are getting close. And when Ashful endorses the Green New Deal, I will start to sleep better at night. ;hm

    Tesla Model 3 Parked in Our Garage

    Awesome Jim. FWIW, I was routinely hitting 44kW DCFC on my Bolt (about 150 mph charging speed). :cool: You just need better DCFCs.

    600 mile ev battery might be coming

    Actually only tesla has their own....the other makers are all standardized.

    600 mile ev battery might be coming

    I"m with Randy but might be useful for heavy transport like EV Semis or replacing diesel locos.

    Thermodynamics the future of heating and cooling using zero fossil fuels.

    During each of these shortage events, I have read that the utilities reserve time to use the pipeline to import gas, and then cancel the reservation (legally) in the last 24 hours....so the 'inadequate pipelines' are running well below 100% capacity during the emergency...and the same utilities...

    Thermodynamics the future of heating and cooling using zero fossil fuels.

    I looked up the EIA data....I was wrong. https://www.eia.gov/todayinenergy/detail.php?id=30672 in 2015 residential heating was 47% nat gas, 37% electricity (heat pump and strip heat combined)... This older link from 2009 has more detail: https://www.eia.gov/todayinenergy/detail.php?id=3690...

    Thermodynamics the future of heating and cooling using zero fossil fuels.

    Dude, if you go look it up, the majority of homes in the US of A are ALREADY heated by air source heat pumps. And the ones that are cooled....100% of those too. I agree completely. The tech just needs to keep improving (it has been doing so steadily), and the installers need to get better at...

    EU Parliament just banned single-use plastics

    Ironically, I AM big on following the European model on most things, bc I think we could be a lot more socialistic, but this leaves me cold. I fear that many people use recycling (much of which gets landfilled nowadays) as a feel good moment to excuse themselves from taking greater action, as...

    Tesla Model 3 Parked in Our Garage

    I am pretty certain that the ohmic losses in the motor and battery are recovered and used to heat the cabin (or the battery) BEFORE they are dumped to a radiator.

    But, but....can it make it to the Twin Cities when its -10°F out??? ;lol I'm just wondering what your next EV will be.....I'm on my third. :cool: Drive it in good health.

    Alternative heat source, minisplits for real?

    I think that NA is a bad market for those. We have all these high-temp passive hydronic radiators, and the HP can't lift hot enough to run them. I thought the air to water systems were low temp, with a blower required for going back to heating air... Does anyone know?

    2018 emissions surged

    Before Paris most countries did not report their FF usage, or did so inconsistently, and did not project their future CO2 emissions. And Climate meetings were pointless argument-fests every 10 years that achieved little of substance. Paris is not what 'Wattsup' tells you it is. It is a...

    2018 emissions surged

    I agree we alone cannot get it done. But it is unclear what you meant by 'we all know where the major problem lies'. I think we are a major part of the problem. Do we all know that?

    2018 emissions surged

    And in the last 10 years we have done LESS than those two countries to reduce our carbon emissions. Both of those two countries have far smaller per capita emissions (from your graph, and the fact they have 4X the population, each), far less wealth to pay for solutions, and both countries HAVE...

    2018 emissions surged

    With respect, if you think the US govt has been captured by the scientific elite re climate change.....I would have to say that as an elite scientist, it certainly doesn't look like we are doing it right! The fedl govt is, and has been controlled, by FF industry shills and climate change...

    Has anybody tried this new style led bulb?

    Dude, the gas fill is a key part of the design. A tiny squirt of helium (or another low MW gas) at the optimal pressure (below atmospheric I think) cost nothing compared to the old heavy metal heat sinks. A kids ballon could fill dozens of these things. Your thinking seems to be that even if...
