Words and Wisdom from the Aviation Genius Burt Rutan at Oshkosh 2024

[@garneauweld1100]

Had a fairly lengthy one-on-one conversation. He chooses his words very carefully. An extremely intelligent individual who likes a thrill for sure.

I’d like to see his mathematics on how wind generators don’t make more energy than they consume in their building somebody’s been blowing smoke and he bought into it

[@daviddowney9331]

Not burt that bought the bill of sale, it's you. It is very, very easy to research the lifecycle cost of wind machines. Not even close. No chance at all without tax factors.

[@EllipsisAircraft]

Wind Turbines* have become somewhat economically viable. It requires a >30-year lifecycle. Which has become possible with certain modern composites. It also requires recycling as much as possible, including the cement base, which may never happen. But these factors could offset the enormous cost of Fiberglass and epoxy production, Neodymium mining, and the eco impact of their production and inevitable waste Much of which must be buried. (Or possibly used as cement reinforcement for roads, etc). Burt ran a bunch of numbers at one point in time. He has been on this twist for at least 20 years. Generally speaking, anything government funded is inefficient and wont work. This is true for certain wind farms of the 80's and 90's. And back then, this was all true. But not so much anymore. This position is simply a product of age. When 20 years is like last year. And it takes a concerted effort to follow the wind industry alone to see what the numbers really are. Of all people, Burt could have been a leader in this area. His interest in solar water heating, fuel efficient aircraft, gas-electric hybrid aircraft, composite design, engineering, and construction. They even designed their own propellers for Voyager. Rutan, Ronz, et. al. Could just as easily be pioneers in wind energy, as well.

Here’s a comprehensive demonstration of wind turbine LCA calculations and payback period - and it’s around 9 months payback. I’m afraid Burt needs some re-educating…! www3.eng.cam.ac.uk/~hemh1/climate/IB%20elective%20LCA-payback%202014.pdf

[@waynerussell6401]

Very entertaining but big faux pas on the emissions figures for electric cars. Multiple studies have found BEV has 4-5 times less CO2 emissions, wheel-to-well than an ICE vehicle, including recycling of the battery elements into new batteries at 97% efficiency. On a clean grid it takes ~ 6 months of use to recover the CO2 in manufacture of a BEV and ~ 18mths on the average US grid mix. And the grid gets cleaner every month, whilst gas cars get worse with use, and last half the Travel distance. The warranty on a BEV is by US law at least 100k miles, but the manufacturers' quote a million miles of use for LFP chemistry (CATL).

Nobody's buying EVs.

@@1225KPH "Data from The International Energy Agency’s Global EV Outlook 2024 makes vibes-based reporting on the demise of EV sales look silly - global EV sales could hit 17 million in 2024, meaning more than one in five cars sold worldwide will be electric. Surging demand for clean, cheap EVs across the rest of this decade will completely change the global auto industry. By 2035, IEA projects 50% of all cars sold globally will be EVs, cutting oil demand between 6-10 million barrels per day, equivalent to the current amount used for road transportation in the U.S. The price differential between EVs and internal combustion engines running on fossil fuels has narrowed so fast that upfront sales prices are barely different. With cheap electricity displacing expensive oil costs, drivers can save big by driving electric. This is huge news for cutting consumer costs, creating new jobs and investment, and cleaning up our air. Everyone, everywhere wants to save money and breathe cleaner air. Soon everyone, everywhere will soon have the choice to make their next car a clean, cheap EV." Forbes July 22 2024 In the first quarter of this year, World sales grew by 25% compared to the same period in 2023. Norway has 95% of all cars sold are electric, Sweden 60% and the Netherlands 30%. China sold 8.1 million EVs in 2023 with more EV sales than ICE. ICE manufacturer Stellantis H1 2024 earnings is 48% less than the first half of 2023 due to falling sales. Record payments made to Tesla for failing in their emission reductions. Volkswagen, BMW and Mercedes-Benz Q1 drop in sales lead to falling share values. TSLAQ FUD is everywhere...

This is a symptom of age more than anything: Burt Rutan is an early adopter of EVs. He leased and commute in the original GM EV. (See: Who killed the electric car?). Rutan raves about it. He also drives a Tesla. But as one point in time (probably 10-15 years ago) BEVs DID fall short on emissions. There is a lot of extra energy in their manufacture. And they have to compete against ICE cars that are so clean, they actually purify the air in some cities. (Fact Check by Top Gear, Porsche claims). If You only consider CARBON emissions. Then yes, the BEV is better. SO LONG AS it is charged by renewable sources. If you have a coal or ga fired powerplant, and account for 30-50% line loss, transformer loss, charger loss, battery loss while charging, and the loses between battery and wheels: then You do arrive at a break-even, near zero sum game. In this scenario, hydrocarbon electricity production, it will almost never pay off the excess cost in carbon alone. And carbon itself is a boogeyman that represents "industry" at large. Carbon is necessary for life on earth. And not too long ago 280ppm resulted in three ice ages, and extinxtion of 90% of all land dwelling mammals. 8,800 parts per million (20x carbon as now) resulted in the Cambrian explosion. Not only new species, but entirely new categories of animals evolved during this time. Plants breathe carbon dioxide. To say carbon will kill life on earth is such a farce, it fails to pass even rudimentary scrutiny by anyone who is not steeped in the religious cult of modern "science"...

[@waynerussell6401]

@@TheJustinJ Did you read any of the supplied references?! Five years ago Carbon Brief published a fact check which shows that a Nissan Leaf pays back the emissions from battery production after less than two years of driving - and emits three times less CO2 in its lifetime than the average new ICE car. Most recently in July THE INTERNATIONAL COUNCIL ON CLEAN TRANSPORTATION published its update of their wheel-to-well analysis: "BEV sedans and SUVs have the lowest life-cycle GHG emissions across all powertrains. The GHG emissions of model year 2024 PHEVs (both sedans and SUVs) are roughly 2 times higher over their lifetime compared with BEVs powered by the average (US) grid mix. Model year 2024 HEVs emit 2.2 times (sedans) and 2.5 times (SUVs) more than BEVs powered by the average grid, and conventional ICE vehicles emit up to 3.5 times (SUVs) more. Notably, compared with BEVs powered by 100% renewable electricity (Norway), this difference increases to 4.9 times more GHG emissions for HEV SUVs and 6.7 times more for conventional ICE SUVs. For new vehicles projected to be sold in 2030, the relative benefits of BEVs are even larger. Conventional ICE SUVs were estimated to have 7.5 times higher life-cycle GHG emissions than BEVs powered by 100% renewable electricity. This is due to the ongoing decarbonization of the electricity grid and improved efficiency of BEVs. Projected new PHEVs in 2030 emit 2.1 times (sedans) and 2.2 times (SUVs) more life-cycle GHGs than new BEVs powered by grid-average electricity. While PHEVs and HEVs have a lower GHG footprint than ICE vehicles, their emissions reduction potential is more limited than for BEVs. BEVs not only deliver emissions reduction at the tailpipe, but across the entire vehicle lifetime for representative sedans." Even with 100% Coal grids such as Poland, Argonne Lab has shown a Tesla Model 3 BEV takes 78,700 miles to reach carbon parity with a Corolla, over the ICE's 12 year lifespan. But BEVs last two (NCM cells) to 3 (LFP cells) times longer than ICE and have second life use in stationary storage and are 97% recyclable meaning future mining is negligible. Rutan is believing (I doubt he has studied it and certainly not published) the 'studies' conducted by the American Petroleum Institute, which represents over 600 companies in the oil industry, who state on their website: "Multiple studies show that, on a life-cycle basis, different automobile powertrains result in similar greenhouse gas emissions." A cut and past technique taken straight from the tobacco playbook! Your closing 'science' bias puts you in the geriatric John Clauser cult. The issue is so critical that no repeated error filled public declarations of superior knowledge can go unchallenged. Rutan is wrong!!

It is more then a mile stone , so far it is a standing record that no one has duplicated. The around the world unrefueled , one take off and one landing flight.

[@EllipsisAircraft]

Scaled Composites built Global Flyer which smashed the voyagers records. But it was not the milestone.

[@joedoe8931]

I never knew that it took more energy to build a wind turbine than it could ever generate in it's entire service life. I knew it took a lot to build but never knew it could never generate enough to even break even,.

[@EllipsisAircraft]

Yes, it can. But not in a low-wind environment. And not if it fails catastrophically before its lifecycle is complete. They can generate several MW each in a stiff breeze. Plenty enough to power their own factory.
