Topic: Fuel Efficiency

A personal anecdote describes the installation of a "hydro booster" in a Jaguar to improve gas mileage through electrolysis. The process involved using electricity to extract hydrogen from water and feeding it into the carburetor. The speaker reflects on past interests in alternative energy technologies that were often dismissed as perpetual motion scams.

A new travel tip advises users to manually disable the "fuel-efficient routes" setting in Google Maps, which is enabled by default. Critics of the feature argue it often results in longer, less efficient travel times in an effort to meet corporate environmental goals. Users are also encouraged to check their privacy settings on platforms like X to prevent their data from being used for AI training.

A report reveals that the federal government uses a "multiplier" of 6.67 to exaggerate the fuel efficiency of electric vehicles in official records. For example, a Tesla Model Y that achieves 65 MPGe in lab tests is recorded as having 430 MPG for regulatory compliance. This accounting allows automakers to generate billions of dollars in tradable carbon credits, which are then sold for cash, effectively subsidizing the EV industry.

Otto Aviation has unveiled the Celera 500L, a new aircraft that utilizes "laminar flow" to drastically reduce drag and fuel costs. The plane reportedly operates at $328 per hour compared to $2,500 for traditional jets. With a 4,500 nautical mile range and a 60,000-foot ceiling, the "flying pickle" could revolutionize regional private aviation.

A rental Volkswagen EOS turbo diesel achieved 43 miles per gallon during a drive from Nice to Florence, highlighting the efficiency of European diesel engines compared to American models. The discrepancy in diesel prices is attributed to US EPA requirements that make diesel more expensive than premium gasoline. The "eco-system" start-stop technology in modern Volkswagens is criticized for being potentially dangerous in traffic situations.

A comparison of diesel fuel prices and availability between the U.S. and Europe reveals significant differences in efficiency and regulation. The hosts discuss high-MPG Volkswagen models available in Europe that are banned in the U.S. due to stringent EPA emissions testing.

The "economy mode" in modern cars, which shuts off the engine at stoplights, is criticized for being unnerving and potentially unsafe on steep inclines. Dvorak recounts a test drive where a vehicle rolled backward before the engine restarted.

The "Ford Focus Studio" reality show is cited as an example of embedded advertising. A discussion on the Kia Soul explores the idea of "green shaming," where driving older, less efficient vehicles like a Range Rover might lead to social or legal repercussions under future environmental policies.

Curry and Dvorak reignite their debate over the "Hydroxy Booster," a device Curry claims improves gas mileage by injecting hydrogen into an engine's intake. Dvorak remains skeptical, dismissing the technology as "bull crap" and questioning the physics of creating hydrogen on-board.

The "Go 60 MPG" campaign, which advocates for higher fuel efficiency standards by 2025, is identified as a project of Environment America. The hosts look into the organization's funding and its expensive federal advocacy offices in Boston and Washington, D.C. They suggest the group is part of a larger corporate-funded environmental lobbying network.

An experiment involving a "hydroxy booster" was conducted to test if feeding hydrogen into a car's intake improves fuel mileage. The device, constructed from PVC tubing and metal plates, uses electrolysis from the car battery to generate gas from water. Initial testing claims an 11% to 29% improvement in efficiency, though skepticism remains regarding potential engine damage from water vapor and the long-term viability of the hobbyist-built system.

Curry describes driving a Renault Twingo with a 1.2-liter engine and compares it to his previous experience owning a convertible Smart Car in Amsterdam. The conversation covers the practicality of small European cars, including the ability to park them head-first in cities like Paris.
