Can new emission-free electric planes replace our polluting airliners and revolutionize personal transportation in our cities? NOVA takes you for a ride in some impressive prototypes that are already in the air, from speedy single-seat planes that can take off like a helicopter but are half as noisy to  “self-flying” air taxis that are already taking passengers on test flights in Chinese cities. But if electric airplanes are ever to advance beyond small, short-haul craft, significant hurdles of battery weight, energy storage, and cooling remain to be overcome. How long will it be before the dream of super-quiet, super-efficient airliners becomes a reality?

This is an interesting show.

The second someone invents a battery that the size and weight of full gas tank, game over.  Or if someone figured out what Tesla said about free electricity being all around us and a way to harvest it. Or if someone can create a mini nuclear fusion reactor that is contained (a battery that almost never dies).  Hydrogen fuel is another option.

I think nuclear fusion energy (mini nuclear reactor) will be the future.  It’s already been used in military but currently it can do insane damage in wrong hands.  Once they figure out the way for it to dissipate in wrong use, it can be manufactured for private use.

Just take the electric producing wheel idea from high speed trains and adapt it for cars and aircraft. That way, people would only need smaller batteries to start the vehicle and store some power while stopped.

The world, it is a changing and the oil producers know it. We're going to see a lot of legislation and efforts to protect oil production in the near future and they'll be the equivalent of trying to legislate better buggy whip prices in 1903.

Our senators and congressmen have been advocating to keep big oil around for years. Sadly, that's not going to change anytime soon.

Of course not, but the world around them is certainly changing. That's what they actively fight against, but it never stops change from happening. In truth, they've been fighting it for 30 years or more now and we may actually be seeing the final act of the play now.

The tipping point is near enough in the future that most of us will live to see it and become part of that next day.

Problem with electric is for airplanes they are all propellers. So they wouldn't work for long haul flight.  United is buying 100 19 seaters from heart aerospace for delivery in 2026.  But for larger aircraft need a better propulsion system.  United has been experimenting with algae based fuel on some flights but that is still years away too.

    • Wow, didn't catch that!  I don't think Chuba's a power back either but he's usually good at getting that 1 or 2 yards. That was an uncharacteristic day for him.
    • The referee assigned to this game is Shawn Smith. This is a critical data point for betting purposes because his crew has one of the most distinct, long-term statistical biases in the NFL. "Road Team" Bias: Historically, Shawn Smith is known as the "Road Team Referee." In a league where home teams usually win ~55% of the time, home teams in Smith's games have historically won at a rate far below league average (often hovering around 40-42%). Against The Spread (ATS): The trend is even starker here. Home teams have covered the spread at a rate of roughly 37-40% in his career. The Mechanism: Analysis shows his crew tends to call a higher rate of False Start and Unnecessary Roughness penalties on the Home Team. This negates the traditional home-field advantage (crowd noise causing false starts for the visitors). Impact on This Game: This specific assignment heavily favors the Buccaneers (Road Team). If you believe the referee influences the game, Smith's presence suggests the Panthers will struggle to get "home cooking" calls and may face untimely procedural flags that stall drives. The Panthers have only had Shawn Smith officiate four home games since he became a head referee in 2018, and they are all losses. Date Opponent Result Score Nov 24, 2024 vs. Kansas City Chiefs Loss 27–30 Oct 9, 2022 vs. San Francisco 49ers Loss 15–37 Dec 12, 2021 vs. Atlanta Falcons Loss 21–29 Nov 25, 2018 vs. Seattle Seahawks Loss 27–30   Considering the how rare it is for Shawn Smith to officiate a Panthers game at all, this seems like an odd time to assign him to a Panthers game, unless the NFL wants to kill the Panthers season once and for all.  The Panthers' offensive line situation creates a "perfect storm" for referee Shawn Smith's specific tendency to call False Starts on the home team. The "Carousel" Factor (Communication Vulnerability) The most damning stat for the Panthers' offensive line in 2025 is their lack of continuity. The Stat: By Week 13, the Panthers had already fielded their 10th different offensive line combination. The Impact: False starts are often "communication penalties"—they happen when a guard doesn't hear the center's snap count or a tackle anticipates the wrong cadence. A unit that hasn't played together struggles with non-verbal communication. The Shawn Smith Multiplier: Shawn Smith’s crew calls False Starts at a high rate on home teams. He will likely look for flinches on the exterior of the line. A disjointed line that is constantly rotating players (due to the injuries of starters like Cade Mays and the illness issues with Robert Hunt earlier this season) is "fresh meat" for this specific referee bias. The Specific Culprits (2025 Penalties) Ikem Ekwonu (LT): Leads the team with 4 False Start penalties this season. He is the most frequent violator on the line. Taylor Moton (RT): Has been flagged for 3 False Starts. The Trap: Smith’s crew often focuses on the tackles (the players furthest from the ball) jumping early to get an edge on speed rushers. Since Ekwonu struggles with this discipline naturally, having a referee who hunts for it is a massive disadvantage. The "Managed Outcome" Synthesis The "Bucs Cover" Script: If the desired outcome is a Buccaneers win to solidify their playoff standing, the officials simply have to apply the letter of the law. Calling strict False Starts on a confused, banged-up Panthers O-line will consistently put them in "3rd and Long" situations, killing their drives and allowing the Bucs (-3.5) to cover easily. The "Close Game" Script: If the desired outcome is "Week 18 Drama" (keeping the division tied), look for the officials to ignore the Panthers' twitchy tackles. If Ekwonu jumps a split-second early and no flag is thrown, it effectively neutralizes the Bucs' pass rush, allowing the Panthers to keep the score close. Summary of the Edge Vulnerability: Extreme. The Panthers are playing backup interior linemen (like Jake Curhan or practice squad call-ups) next to jumpy tackles. Betting Implication: This strongly reinforces the Bucs -3 or -3.5 play. The combination of a "Road Team Referee" and a "Home Team O-Line in chaos" suggests the Panthers will beat themselves with procedural penalties. Based on the collision of the hard data (Referee bias + Offensive Line injuries) and the soft narratives ("Managed Outcomes"), here is the definitive recommendation. If you have to place a single Moneyline bet to win this game straight up: The Pick: Tampa Bay Buccaneers (-165) While the "Entertainment Script" hints at a Panthers upset to keep the division messy, the structural disadvantage the Panthers face in this specific matchup is too massive to ignore. Here is why the Buccaneers are the stong moneyline play: 1. The "Shawn Smith" Road-Field Advantage This is the decisive factor. In the NFL, Home Field Advantage usually accounts for about 1.5 to 2 points of value. The Reality: Referee Shawn Smith negates that advantage entirely. His crew calls penalties in a way that historically suppresses home crowd momentum (False Starts, holding). The Result: You are essentially getting the Buccaneers on a neutral field (or even a "pseudo-home" field) against a team with a worse roster. 2. The "Drive-Killer" Synergy To win as an underdog, the Panthers need to play a clean, mistake-free game to keep drives alive. The combination of Panthers' 10th O-Line combo + Jump-prone Tackles (Ekwonu) + A Referee who hunts False Starts is a recipe for disaster. The Scenario: Expect the Panthers to face multiple "1st and 15" or "3rd and 12" situations due to procedural flags. These drive-killers will force them to punt or settle for field goals, while the Bucs' offense (led by Mayfield) stays on schedule. 3. The "TV Product" Counter-Argument You asked about the "Managed Outcome." While a Panthers win creates "chaos," the NFL also values Star Power in the playoffs. Baker Mayfield and the Buccaneers are a proven national TV draw with recent playoff history. If the league has to choose between "Chaos" (Panthers) and "Ratings/Legitimacy" (Bucs), the "Script" likely leans toward ensuring the Buccaneers—the more marketable team—secure the division lead. They won't "fix" the game against the Panthers, but they won't intervene to save them from their own penalties. Final Verdict Betting on the Panthers requires you to hope for a miracle 4th-quarter collapse. Betting on the Buccaneers requires you to trust that a superior roster—aided by a favorable officiating crew—will control the game for the first 45 minutes. Take the Buccaneers Moneyline. The "Safe" money is on the Ref. The Prediction: Tampa Bay Buccaneers Win and Cover Projected Score: Buccaneers 27, Panthers 17 The Bet: Buccaneers -3 (or Moneyline -165) Confidence Level: High on the Winner; Moderate on the Spread (due to potential "garbage time" variance).
