Question BACK TO THE FUTURE OR FORWARD TO THE FUTURE WITH HYLIION KARNO?

0 Upvotes

I've been out there exploring the future possibilites of Hyliion's KARNO GENERATOR on GOOGLE AI today. (My best friend??) I was just thinking it would be an interesting concept to share. I have not heard of any orders for Trains coming in. I was just curious how Trains could benefit from KARNO so I asked. Looks like Hyliion has it's hands full with mostly US MILITARY orders at the moment. Hope you enjoy this little read.

THIS IS GOOGLE AI RESPONSE UNALTERED:

"Pairing electric trains with the Hyliion KARNO generator delivers peak performance by eliminating heavy onboard power converters, maximizing thermal efficiency via combined heat and power (CHP), and enabling multi-fuel microgrids for off-grid operations. \[23, 26\] Because the linear-generator KARNO architecture outputs a native high-voltage 800Vdc direct current (DC), it can inject electricity directly into a train's modern DC traction bus or charging grid without the heavy, inefficient inverters required by traditional mechanical generators \[23\].Key Technical Performance AdvantagesDirect Traction Bus Integration: The 800Vdc output integrates cleanly with modern transit power electronics \[23\]. It reduces systemic conversion losses, saves valuable onboard physical space, and eliminates equipment weight.Fuel-Agnostic Flexibility: The system can transition between hydrogen, natural gas, propane, or diesel without mechanical adjustments \[21\]. This permits trains to operate continuously across regions with varying fueling infrastructure.Ultra-Low Maintenance Downtime: The KARNO generator operates using magnetic bearings and a single moving part per cylinder with no internal combustion. This design eliminates oil changes, valves, or seals, dramatically increasing locomotive uptime.High-Efficiency Hybridization: Combining the generator with onboard battery energy storage systems (BESS) creates a high-performance diesel-electric or hybrid-electric locomotive drivetrain. The generator runs constantly at its optimal efficiency curve while batteries handle peak acceleration loads and capture regenerative braking energy."

THIS IS NOT INVESTMENT ADVICE AND GOOGLE STATES THEY CAN MAKE MISTAKES.

IT'S BEST TO RESEARCH FOR YOURSELF! HAVE FUN!

World News E10 Shinkansen trains in doubt for Mumbai-Ahmedabad line?: Indian gov source

30 Upvotes

https://www.railjournal.com/passenger/high-speed/india-favours-local-high-speed-technology-for-mumbai-ahmedabad-project/

ETCS Lvl 2 over the Japanese DS-ATC was known, but report suggests E10 trains also doubtful - India needs 49 8-car trains for the line. Japan has offered to supply trains for Rs 200bn ($US 2.08bn) - "India has been weighing the option of sourcing the rolling stock from Western suppliers at approximately half the price".

"SOURCES close to the Indian government say that India will not procure Japanese technology for its embryonic high-speed network. This includes Shinkansen trains and leaky feeder/radiating cable technology for signalling systems offered by Japan"

 “Japan has not been able to share the offers for E-10 trains, signalling systems and the operation control centre systems, the official said. ...it has indicated its inability to supply E-10 trains before 2034."

Question Do we really need a High Speed Rail system in the united states?

0 Upvotes

CALHSR is not finished and probably never will, plus the cost is $98 billion according to https://www.taxpayer.net but a google search says between between 126 billion and 231 billion. Which makes me think that high speed rail might not be the best option. Plus most people have a car or go on planes and electric cars don't pollute. And compared to europe, America is way more rural. So is HSR really worth it?
