    Significant Avalon advances

    Source: TNGA-based 2019 Toyota Avalon features new hybrid system - Green Car Congress

    Avalon Hybrid. A new TNGA 2.5-liter four-cylinder Dynamic Force Engine is more fuel efficient, runs cleaner, and is more powerful than previous iterations, and features enhanced thermal management. Technologies required include: Dual VVT-i with VVT-iE (Variable Valve Timing intelligent system by Electric motor); D-4S (Direct injection 4-stroke gasoline engine Superior version) direct injection and laser-clad valve seats; longer stroke (4.07 inches; bore remains at 3.44 inches) and high compression ratio (14:1); multi-hole direct fuel injectors; a variable cooling system; cooled Exhaust Gas Recirculation (EGR) system; and a full variable oil pump.

    Instead of oil pressure, its Dual VVT-i with VVT-iE variable valve system employs an electric motor to control variable valve timing, which aids fuel efficiency...

    Tesla: WTF is going on

    So, I've been a fan of Tesla since the Roadster. I remember drooling while reading about it on Digg.


    Tesla is far from perfect and always has been. I test drove a 40kwh Model S -- one from the first year of its production -- and... it wasn't great. The turn signal and wiper controls were on the wrong side. There's a distinct lack of buttons for climate and audio controls. No AUX connection. They burn through 12v batteries. The big display is distracting. These are little kinks that needed hammering out, nothing insurmountable, but certainly noteworthy and substandard on a $50k+ car.


    But it seems like in the last 6-9 months they've gone off the deep end. Burning crazy amounts of cash, a trend that seems to be increasing rather than decreasing. Burning bridges with suppliers left and right, first Mobileye now Grohmann Engineering and Alcantara. CEO and CFO saying ridiculous and contradictory things on official SEC filings and investor calls, like that the robots are both being...

    Cali Public Utility Deals a Blow to Natural Gas' Electricity

    Seems the biggest bang for the Natural Gas buck, comes via peak usage times. So now, the public utility commission is hitting the fossil fuel industry right between the eyes, despite natural gas's 'clean' verbiage;

    ".... The California Public Utilities Commission approved an order Thursday that will require PG&E Corp., the state’s biggest utility, to change the way it supplies power when demand peaks. Instead of relying on electricity from three gas-fired plants run by Calpine Corp., PG&E will have to use batteries or other non-fossil-fuel resources to keep the lights on in the most-populated U.S. state ...."
