  • Liquid hydrogen is the only viable carbon neutral fuel source for air travel due to its energy density. Reducing weight is the #1 most important factor in building aircraft. This shouldn’t come as a surprise. It’s common sense. Hydrogen can be produced via electrolysis, whether you want to whine about the current situation with natural gas based production or not. It is the only option we know about that is capable of addressing the issue of carbon emissions from air transport. Unfortunately, liquid hydrogen much less energy dense than kerosene, but it’s all we have. The important part is that hydrogen is a clean fuel source which can be produced via clean energy.

    Unless you have a Nobel Prize winning alternative energy solution in mind to power aircraft with zero carbon emissions with an energy density as good or better than liquid hydrogen, your advocacy against its use is an impediment to progress.


  • Your fears are making you advocate to impede progress. The government supercedes the fossil fuel industry. That is my point. Yes, there are many barriers to us seeing any meaningful action, including regulatory capture and general corruption by the interests of the fossil fuel industry, but that is absolutely not a reason to give up on addressing the issue of carbon emissions in air travel. The fossil fuel industry advocates are boogeymen. At the end of the day they have no power over the government, and you are acting like they’re “too scary” to be confronted.

    Moreover, that is not the point when it comes to technological advancements to make modern society carbon neutral. We should celebrate every advancement that gets us closer to that goal. And yes, I am fully aware that we are very late and millions of innocent lives will likely be lost to the affects of climate change before we get there. But that is all the more reason to work harder.


  • You are a person arguing to do nothing to attempt to solve the problem of CO2 emissions from airplanes, which account for a very large proportion of global emissions. You are arguing incessantly about why progress shouldn’t be made. Cut it out. The energy density of liquid hydrogen makes it the only viable fuel source for air travel that isn’t a petrochemical. That’s why this is important. Fuck your whining about boogymen in the fossil fuel industry as a backdrop to this. It’s irrelevant. What matters is progress, because zero carbon air travel is probably the most difficult challenge we face in cutting fossil fuels out of modern society.




  • To my knowledge, Signal is the only verifiably secure encrypted messaging app that’s market ready. Signal is fully open source, including its encryption algorithm which has been tested numerous times and even gotten government agencies like the FBI all butthurt that can’t break it or get a backdoor from the devs. I have a friend whose cryptography professor contributed to the project.

    It was only in recent years that Signal upped their game enough with the user experience for me to start recommending it to friends and family. In 2013, when I first recall trying it out, Signal was more clunky and always wanted to be your default SMS app. I didn’t like that, because at the time they didn’t have a client to send messages from your computer.

    Nowadays they have an desktop app that syncs with your phone, video calling, and even stories – which some people find weird but I’m all for non-Zuccubus owned private and secure alternatives to social media. I’m pretty sure anyone on Lemmy would love to pull more power away from these surveillance based ad companies and stop being data cows.

    Tl;dr: Fuck the Zuck, keep promoting Signal, democratize the internet
