    You don’t have to leave Colorado and go to Belgium to find examples of energy craziness. The Colorado state “regulators” are letting an electricity provider fleece its customers.

      Insanity.

      I rode by a city owned PV solar panel bank in the area and noted that it was covered by dust and bird droppings. Even when the sun does shine, this neglect to maintain the panels represents waste on top of waste.

      • Jason Calley says:

        In Florida especially, I have seen many state owned PC panels powering emergency call boxes on remote highways, and a very large fraction of them are positioned such that they are effectively useless. Invariably, they will be mounted pointing straight south. That works well if they are in an open area, but sadly, the PCs are pointing straight south even in locations where there are large trees shadowing the site and the only open sky is to the east or west — or sometimes there is no open sky at all! I imagine installers that either didn’t know better, or, more likely, installers saying, “This is stupid, but my manager’s manager says to point them south!”

      The people know what they want and they are going to get it, good and hard.

    That diesel generator & the Tesla looks like something the Grifftard would do to save the planet.

    • R Shearer says:

      Maybe it was burning biodiesel, produced from palm oil on land that was previously rain forest.

      • Margaret Smith says:

        Indeed! It is like growing corn for ethanol but having to use more fossil fuel to produce it than the ethanol can even replace. But, of course, the whole green energy thing is a scam anyway.

    • Phil. says:

      Well a diesel generator at constant load and peak efficiency setting operates at about 50% fuel efficiency, well above that of a gasoline engine operating at variable load. Combined with the better torque of an electric motor and regenerative braking it’s probably better than a gasoline vehicle, not the optimum solution however. ;-)

      • Johansen says:

        Yes it’s ironic isn’t it. When the Belgian P.D. want reliability they just go the diesel gen set sitting nearby. To heck with the acres of PV panels sitting on the roof

      • richard verney says:

        It would be far better to use a diesel powered car. There are plenty on the market.

        • Squidly says:

          Indeed … Phil completely ignores all of the other parts of the transfer from fuel, to generator motor, to storage, to car, to storage, to car electric motor.

          He is touting the 50% efficiency (which is BS) and completely ignoring all the other points where energy will be lost. Even if that generator were producing at a 50% efficiency, by the time the energy is actually used, 50% of that 50% efficiency will have gone to waste, easily.

          I laugh at people that pretend that by transferring this energy from one form to another somehow creates efficiency. Stupid stupid people .. just like Phil.

      • Binyamin says:

        Well, you can be sure that diesel generator is not anywhere near constant load and peak efficiency.

        • Johansen says:

          Correct. Diesel engine 35% efficiency to shaft. Then you have a generator, then you have a transformer and rectifier, then you have batteries, a drivetrain. All have less than 100 percent efficiency. Overall efficiency probably no more than 25% which is what you’d get from a gasoline auto.
          If a diesel engine actually made usable electric power at a ratio of 1:2 with the BTU’s contained in the fuel, we wouldn’t need thermal power plants. The very best cogeneration plants only achieve around 35% eff. and that’s with a “combined cycle” where you are utilizing the exhaust gases to make steam and turn a steam turbine, in addition to using fuel to turn a gas turbine

          • oeman50 says:

            Johansen,

            Good points on the diesel, but I am afraid I will have to disagree about the cogen and combined cycle plants. Cogen plants may have an electric efficiency of about 35%, but the use of heat that would otherwise be wasted to a condenser makes the heat efficiency much higher, 50 to 90%. And modern combined cycle units are .run at efficiencies as high as 60%

          • Johansen says:

            Oeman50… okay, there you go!
            And the low pressure steam from cogeneration plant can drive desalination, too

          • Well, the best diesels, like the naval engines buildt by Warsila, reach 50-55% MECHANICAL efficiency. But this is not the case. And in the process of transforming movement into electricity, transferring electricity to the battery, transferring electricity from the battery to the engines, a lot of electricity is lost. Here probably we have an efficiency equal to a gasoline engine. Best mode to increase efficiency: REDUCE WEIGHT of the car (smaller cars and alluminum chassis).

        • Johansen says:

          Then you have to consider CAPEX (capital expenditure) not just operating expenditure of fuel and so on. You have a dedicated generator with fuel storage with a host of safety/environmental measures, a PV array on the roof, a fleet of Tesla cop cars (sexy but not cheap)
          I’m all for Tesla and electric/hybrid cars, I think they’re great; but the whole idea is you are reducing GHG emissions

      • Geoff Sherrington says:

        Phil,
        Plus there is the efficiency loss from carrying that large battery weight everywhere you travel. Don’t underestimate this drawback, it is one of the main factors that will kill electric cars, if they indeed are to die. Geoff.,

        • Phil. says:

          Offset somewhat by the lighter drivetrain of the electric vehicle, far fewer moving parts etc., the power to weight ratio of electric is better. Perhaps that’s why the cops like the electric, it can out accelerate anything they’re chasing?

          • Squidly says:

            No Phil, the “power to weight” ratio is not better. The only reason why an electric car can accelerate quicker than a combustion car is, in a single word, torque .. I will leave you to figure out why that is.

          • Phil. says:

            The only reason why an electric car can accelerate quicker than a combustion car is, in a single word, torque ..

            I believe I mentioned torque in my post. An electric motor has maximum torque at zero speed whereas a gasoline motor has zero torque at zero speed. Gas motors have quoted peak HP usually near their peak rpm whereas electric motors have quoted average HP and are capable of 4 times that at peak. When it comes to normal driving the electric motor hp/torque is more relevant, Diesels have peak torques at a lower speed which is why they’re better for hauling loads.

          • scott allen says:

            Phil most cops do not like electric vehicles. As a police officer in a large midwestern city an electric vehicle will run out of a charge before 1-8 hour shift, requiring the vehicle to be out of service for 2-3 hours. in the USA cities are spread out and it is not unusual for a police car to average 150-200 miles in a shift, exceeding the range of most electric vehicle.
            A police car is used by all three 8 hour shifts, you would need AT LEAST 1 extra vehicle to be on standby while the other vehicle is being recharged. Modern police vehicles are required to carry over 2,000 pounds of extra equipment (guns, radios, computers, medical kits, cages and thicker glass) not to mention push bars and enhanced electrical generating capacity to power all the extra lights and emergency equipment. Thus they are purchased with a “police package”.
            Most police departments are moving to SUV’s due to the need of carrying this added equipment.
            Acceleration means very little to a police vehicle (it is really hard to out run a police radio or a cities camera system).
            A tesla may be ok for a family vehicle the the requirements for a modern police vehicle are very different

        • Squidly says:

          Geoff,

          Electric cars have been around since the car was invented. In the very early 1900’s, the electric car was the predominant form. Since the advent of the combustion engine, the electric car lost that battle, long ago. The electric car is a novelty and completely unsustainable as we do not have the natural resources available to replace every combustion vehicle on the road today with an electric one. Not to mention the environmental damage in doing so would be absolutely catastrophic (another tidbit these electric car morons fail to acknowledge).

      • R Shearer says:

        Perfect, so long as the car’s battery is slowly charged and the car is not driven, it has efficiency approaching that of a diesel, less inversion losses and capital expenses for said equipment, etc.

      • GW Smith says:

        Put the diesel on the Tesla as one unit and you have a mini diesel locomotive. Pollution free unlimited energy is still a long way off.

        • Phil. says:

          Yes as I pointed out below. Basically a hybrid. As I was suggesting above storing the electricity in a battery instead of carrying the diesel engine with you gives weight advantages. You can design the generator for maximum efficiency without having to worry about the weight. Also the ‘flat’ design of the battery pack allows it to be mounted low in the vehicle which makes for very good stability.

      • Nutation_discombobulation says:

        Efficiency is pointless when you consider NOx and SOx emissions. If they were serious about real green(red)energy they would just use a modern petrol engine with highly refined petrol and be done with it!

  5. spike55 says:

    Maybe they are using biodiesel ;-)

  6. Jimmy Haigh says:

    Why don’t they just tow the generator behind them. Hey! Endless electricity! All they’d have to do is fill up the generator with diesel every couple of days.

    • Phil. says:

      Like diesel-electric automotive do?

      • Phil. says:

        Sorry should be locomotive.

      • Phil. says:

        Should be locomotive.

      • RAH says:

        yea, I’d like to see a solar powered unit do what diesel electric drives do. During WW II the largest German assault tank built was the Panzer VIII Maus (mouse). It used a gasoline electric drive and then later a diesel electric drive.

        The vast majority of all submarines built by all combatants in WW II were diesel electric. When I was stationed at Flint Kaserne in Bad Tolz the back up generator unit was a Diesel electric unit pulled right off the production line for U-boats and installed in a shed next to the quadrangle. I wonder where it is now.

        • Johansen says:

          Rah, you had me going, there. I thought the Tiger was the largest. Yes, that Maus is a giant, even tho never made it to production. 1200 hp engine/generator driving electric motors at each track. 1-meter wide tracks. Looks too heavy at 200 tons to make it over many bridges, though. A fully loaded 18 wheeler is only 40 tons, as you know. I would guess these would have to be utilized on paved surfaces or very stable ground.
          Yes, the diesel electric combination disconnects the engine from the ultimate drive shaft (or propeller shaft, or whatever). Allows one to steadily run the engine at optimal rpm’s, and put the variable load on electric motors. The auto transmission (fluid coupler, etc) on modern heavy equipment allows you to do the same thing with the engine – constant optimum RPM’s. This was all thought out in the 1930’s. Amazing

        • spike55 says:

          Did, y’all know that the Paxman Valenta engine as used by British Rail in early Intercity 125 diesel electric train engines, is also used in submarines and small ships.

          https://en.wikipedia.org/wiki/Paxman_Valenta

          ( note, while I have used Wiki here, I do not use Wiki for climate information)

        • spike55 says:

          I wonder how long a solar charged battery would last under passenger train power requirements. ;-)

          ps Modern passenger trains, be they diesel-electric or overhead electric of often use smaller electric motors on every coach to provide traction rather than one big drive unit.

    As RAH sees it:
    How this POTUS is winning for the US.

    Here is the bottom line as I see it. The left in this country with the willing acquiescence of the RINOs have used oil to tamp down and control the US economy for decades. The excuse for that is of course environmental causes and “climate change”. President Trump has destroyed that gambit for the time being and is well on the way to fulfilling his promise of making the US Energy independent. The US has become the largest oil producer in the world since Trump was elected according to the EIA. https://www.eia.gov/tools/faqs/faq.php?id=709&t=6

    We are producing over 15% of the worlds production and as the worlds largest consumer we use 20% of the worlds production. But the US output is continuing to climb with Texas alone projected to surpass Russia as the third largest producer in the world before the end of this year. So it seems that true energy independence is going to be achieved which those who have been in control of this nation for decades have claimed many times in the past was an impossible goal using the doctrine of “drill baby drill”.

    This oil dynamic and the deep and very diverse US economy gives the US tremendous leverage in it’s trade negotiations and President Trump is using those hammers to gain better deals for the US. This leverage applies to both net exporters of oil like Canada and the countries of the Middle East and Central Asia and especially Russia and to net importers like China. Those Countries in the weakest negotiating positions are the countries that have large trade surpluses with the US which includes Mexico, Canada, and most importantly China and those who’s economies rely heavily upon oil exports like the countries in the Middle East and Central Asia such as Iran and most importantly Russia.

    Fact: North Korea is a proxy state of the PRC. What Kim Jong-un does is what China wants him to do. They could get rid of Kim and replace him with any of several that are in the inner circle of power in N. Korea any time they want. Detent with N. Korea, both nuclear and otherwise, was a ploy by China to try and buy Trump off to prevent the trade disaster they are facing. Trump did not take the bait. So now China is in a very disadvantageous position in the trade negotiations. It is already beginning to tell on their economy. https://theconservativetreehouse.com/2018/09/02/august-report-chinese-manufacturing-growth-slows-to-a-14-month-low/

    Fact: Canada carries a large trade surplus with the US. Their leadership botched it when they snubbed the United States during the NAFTA negotiations and now faces a heavy political price domestically as they have come crawling back, hat in hand, after Trumps Administration has negotiated a separate deal with Mexico and has started the process to end NAFTA.

    Trump has the upper hand on China, Canada, Russia, and Iran and has used our resources and his own innate ability to gain it. Their only hope is the same hope the left and the DC establishment has. To destroy Trump or to at least compromise his power by gaining control of at least one house of Congress.

    • R Shearer says:

      Presently, U.S. net production exceeds its consumption due to fracking technology. The U.S. has also increased export of natural gas and derivative fractions and products and looks to export more coal.

    • Johansen says:

      Rah, many good insights, there. When you think about what we’ve done to destroy ourselves the last few decades it’s maddening. The US is blessed with so much energy it’s ridiculous – coal, oil, gas, Uranium, hydro, wave, wind, etc. Think of all the money we’ve needlessly shipped off to hostile nations. We have never even utilized breeder reactor technology which we invented and Jimmy Carter relegated to the dust heap because somebody advised him we had plenty of Uranium. There’s still vast areas of known oil/gas reserves that are ‘off limits’ in the US. We don’t even know the extent of it

      • RAH says:

        What Trump has stopped and what we don’t want to go back to:
        “The Eagle and the Arrow – An Aesop’s Fable

        An Eagle was soaring through the air. Suddenly it heard the whizz of an Arrow, and felt the dart pierce its breast. Slowly it fluttered down to earth. Its lifeblood pouring out. Looking at the Arrow with which it had been shot, the Eagle realized that the deadly shaft had been feathered with one of its own plumes.”

        • Nutation_discombobulation says:

          I wouldn’t hold my breath if I were you….Trump sadly sold his soul in the 90s, all his subsequent actions carefully orchestrated by Bolshevik-neocon choreographers realising the final scenes of Zionist world dominance, and goy enslavement.

          If Americans could see themselves as much of world sees them, then they would understand why the Arabs see them as the Great Satan, and how your people are being fleeced of your wealth, power and critical thought, ultimately to provide cannon fodder and tribute as a mere serfdom of Israel.

          It’s not anti-Semitic to point this out, it is not hate speech; the earth is a circle, there is no denying it.

          • RAH says:

            I don’t give a shit how the world sees us and care even less what some wacko anti-Semitic thinks. I would have been one of the American soldiers that executed the Nazi guards at Dachau. And no, I’m not Jewish.

          • Johansen says:

            Nutation… I get your point, but the big banking families and big-money global foundations aren’t even Zionist for the most part. They look with contempt on modern Israel, or at a minimum don’t care. A reestablished Israel is obscurantist to them. Moving the US embassy and so forth is not viewed favorably
