Hi. Absolutely fantastic photos and explanations. I have really enjoyed watching and learning. I would put myself somewhere above amateur moving towards semi something lol.... if you ever want to see snowy owls in the wild and without a permit.. let me know. Outside of Barrie Ontario, Canada. We have tonnes in the fields around where I live. They are tricky to get close to but lots of opportunities.

Who "knows" of Joseph Needham? Does his work repay study? Our legacies are fleeting memories. By the middle of the 21st century, who will "know" of Joseph Needhan? Careful as we will, careful as we go.

Its difficult leaening more about this Tartary place. Id be great to have more scholars approaching the topic instead of laymen who really do have some great things to say. Id like a bit more of cross referencing from some english speakers. Id at least like someone to poke holes in some of the these people are saying

Hi , can we make nitrogen fuel cell or nitrogen air battery , fuel cell or battery that works on air only ? Oxygen to air cathode , nitrogen from air to air anode , What do you think , thanks
@donflamingo7954 жыл бұрын
Nitrogen fuel cell would definite create Nox, which is harmful
@drjwilber4 жыл бұрын
nope - nitrogen virtually unreactive - hence 80% of air we breathe
@5688gamble3 жыл бұрын
You mean react nitrogen with oxygen? N2 is a very stale molecule, it's reaction with air is endothermic (requires more energy to break the N to N bond than is obtained in the forming the new bonds) and nitrogen oxides (NOX) are some of the worst pollutants produced by cars. Alcohols or hydrocarbons (like we use now) produced from biomass or reaction of hydrogen with carbon dioxide make more sense to me than hydrogen itself tho as they are liquids at ambient temperatures and pressures and in an ideal system any CO2 released by these vehicles would be getting taken in at the other side making more fuel anyway. Remember when someone thought using hydrogen in passenger airships was a good idea? They thought it was safe! Didn't work out too well!

Can we make nitrogen fuel cell , air have 78 % nitrogen , then we can have free energy :)
@eddieyip95465 жыл бұрын
Not likely. N2 is rather stable which is extremely endothermic (i.e. energy consuming) to break the two atoms apart. It will be more likely as the final product of other potential nitrogenous fuels.

Solar cells generate electricity. Batteries store electricity. The two technologies accomplish different tasks. So one cannot replace the other. In other words, you still need batteries to store the electricity for night time use when the solar cells are not generating electricity.

You could use capasitors which is less toxic in its own way. But they come with a number of new problems.
@Sailor376also5 жыл бұрын
You are quite correct, however, consider,, many of the devices that are discussed are devices used in ambient light conditions. Humans walking, talking, classroom, office,,, any area that is lit enough to function in, there is enough light for an efficient photovoltaic to generate sufficient for a low power device. My desktop hand calculator here in my office at night, functions (only just) in what might be 1/100th of equivalent daylight. Computer screen in front of me, and a 6 watt table lamp in the room behind me. And the darned thing does work. I would think that is must have a capacitor in the system to even out the current,,, and a capacitor is a type of battery/storage device.

Ulrich Hager i have just been watching ty vids about Ethanol and Methanol fuel cells. There’s one big problem with Hydrogen fuel cells( don’t know if Ethanol or Methanol are the same) reguire Platinum, I don’t know if the Platinum needs replacing after a while, or if they last as long as needed. But considering Platinum is so rare wouldn’t it be better to use the Hydrogen, Methanol, Ethanol, and liquid fuels from Algae and Pyrolysis in a ICE instead. At least they would be Vehicles the owners or local mechanics can work on!. While avoiding the waste of hundreds of millions of cars being crushed. Sure the day may come when fuel cell technology can avoid precious metals, but while that research is happening we could be phasing our ICE when they come to the end of their repairable life. Also the first Compressed Air Vehicles ( CAV) TATA’s ‘Airpod’ is due to go into production by 2020 . If that takes off as I expect it to, then shortly after that Fords will release their new ‘Model T’ CAV using a much more efficient CA engine design than in TATA’s ‘Airpod’. I truly believe in 5-10 years time we will have a combination of car fuels including CA, Hydrogen, Methanol, Ethanol, and bio fuels from Algae and Pyrolysis, and EV making up about 1/4 of the market.
