How can we make clean-green airplanes that travel as fast as typical passenger jets?

There are all kinds of possibilities in theoretical physics.

The problem is the math as we understand it, for instance the "big bang theory" requires an infinitely dense mass in an infinitely small space (to say nothing of "dark matter") but the math as we know it creates a discontinuity when you try to divide by zero...

it is a hole, nothing can exist where you divide by zero, it is a non-space!

On the other hand it would only take a few horsepower or about 3000 watts to accelerate a tiny mass to a near light velocity...

so how do you trick something the mass of the Enterprise (whichever one, even the aircraft carrier would do) into behaving as if it has the mass of a single electron?

And is it bad luck if a black cat walks across your keyboard?

It sounds like the days of fast travel around the world are numbered.

No feasible alternatives to fossil fuels seem to have been found yet for fast-moving airplanes. Man needs to understand that fossil fuels surely won't last forever at the rate we are using them even today. Something needs to give somewhere down the line.

When I was about 10 years old the "experts" predicted that we'd be out of easily accessible oil by now...but technology improves with time. Cars don't get 10 mpg any more and the definition of "easily accessible" has shifted.

Still, yes, it is a limited resource and will eventually run out. Just like the 50% of rivers that used to have salmon runs (believe it or not salmon used to make it up the Snake River as far as Burley ID!).

But where would we be if not for the electrical generation from the dams on the Columbia river?

Yep, every kind of energy has a cost. Nevada Solar One kills untold numbers of birds with it's nearly 500 acres of mirrors focused on a heat collector-besides that it is very efficient-but at what cost to the control of insects and pollination that those dead birds would have done?

And here's a question that you will hear no one ask-

When you use Wind Turbines to extract tens and hundreds of thousands of megawatts of energy from the atmosphere, energy that may otherwise have turned into thunderstorms and have had a cooling and cleansing effect on the environment, what will the long term effects be?

If we put all of the carbon that is in fossil fuels in the ground back into the atmosphere do you know what we would have?

A CO2 level as it was during the period millennia ago when the Earth was warmer and you know what else? It was the period the greatest biodiversity the planet has known!

Yeah, there were no humans or polar bears way back then but you know what?

The critters and plants of that time didn't miss either one and who died and made some climatologist the new god of what is the perfect environmental conditions on Earth?

99.9% of the life that has existed on Earth is extinct and the vast majority of that happened before Neanderthals let alone Homo Sapiens-

our days on Earth are numbered regardless...

Michio Kaku: 3 mind-blowing predictions about the future

I would like to live long enough to eat venison from a deer I shot with a flintlock though...I need a flintlock but I'm working on that. At my age becoming picky is earned so no, I'm not going to settle for one of the crappy Pedersoli imports with a rifling twist rate suited to conical bullets. 1:66 or so would be fine for spit patch and round ball...

Mother Nature is not warm and cuddly, that is a kitten-and even kittens have pointy teeth and sharp claws. Mother Nature is the frigid vacuum of space that we are an insignificant oasis in, a vacuum full of asteroids, supernovas, pulsars, gamma ray bursts, rogue stars, planets and even stray black holes!

Seriously, the continuation of high speed travel by airplane-pretty or not given the A-380-is really a pretty low priority all things considered...

Happy New Year!!!

Mother Nature and Father Time could care less how long naked apes can continue to soar near or exceeding Mach speeds through the atmosphere of this planet. Man may face long voyages in sailing ships all over the world once again someday. Man may very well someday need to seek out new planets for his survival, at least for civilization as we know it to be able to live in a high-tech state. Outer space is the final frontier indeed. Man needs certain forms of energy to sustain a high-tech lifestyle. Does Mother Nature care if we ever go back to the caves or the bush again? Perhaps, man will not last forever, but certainly some other intelligent life might take over. The universe is bigger than we can ever dare imagine.

Strange how little is mentioned in the lame stream media about sustainable alternative fuels. We use it in a number of FBOs now with similar burn rates of JetA. One company uses non recyclable plastic to make it. Another uses landfill waste. Cuts carbon emissions by something like 80%. If we could viably produce enough for all diesel burning vehicles, that would be a huge reduction in bad pollution, including CO2, plastics, and landfills. Nothing positive is ever acknowledged by the alarmists. If it was, the crisis can’t continue.

FBOs?

We should look at the whole smorgasbord of energy possibilities. We should also slow down our fertility rate drastically. How many humans on this planet does it really take in this world to sustain a modern-level of civilization and technology as we know it today? I guess no more than 10% of our current numbers on earth. To have smartphones, airplanes, automobiles, roads, electricity, Internet, TV, air conditioning, automatic dishwashers and such, it takes so much manpower to make that all happen. It take a certain amount of energy to power and sustain modern first-world living. An African-Bushman-level population or American Indian tribal population will support a hunter/gatherer society but not a jet age, a digital age or a space age. Fewer than 10 million people might support an ancient Roman Empire.

Well, you can adopt the Margaret Sanger approach. Eugenics. 43 MILLION babies were slaughtered in the womb last year alone in the US. Hitler tried the same with millions as well. Or how about soylent green. Kill a bunch of people and supply their bodies to the food production plants. And where the heck did you come up with 10% of our current population?

China had very stringent birth controls with their one baby rule and now regret is as the natural course of gender balance was disrupted. They are backing off that philosophy. Go ahead and believe all the doom and gloom. Or better yet, be a realist, not an idealist. Live your life and do what you feel is best to save the planet. Get sterilized. That’s one small step, and then you can go toot your own horn.

Oh, and btw, an FBO is where General Aviation goes. More airports than all the airlines. And SAF used by them, by private jets, by trucks, by ships and trains will do wonders to reduce CO2 levels. Let’s do what we can without drastic measures affecting countless people. Who the he// are we to decide who lives and who dies, because that’s what it’ll come down to. Or maybe another little thing called a virus, or maybe a bigger thing called an asteroid.

The 10% figure I read several years ago online but can't remember the source. I propose reducing human numbers by reducing conception rate, not killing. People with means should unselfishly adopt children in need of homes.

Be a virgin
Beat off
Do blow jobs
Use contraceptives
Practice same-sex sex
Adopt
Get a vasectomy

All good ways to lower our numbers without killing.

 

[Pervis]

All a personal choice. Isn’t that the mantra of the pro abortion folks? Irresponsible sex and kill a baby for convenience. That’s killing people and provides for the greatest reduction in population aside from world war. Both undesirable from my perspective. You think new options to facilitate your population reduction won’t come along, like corona?

BTW, how did this devolve from your original question about greener aircraft? I gave you a viable solution available and becoming more widespread today yet like the alarmists, nothing positive is ever acknowledged. Or are you just a troll stirring up the pot? At best you are a very naive individual with very little real world experience.
