Default Re: Air Power

Ok Voltswagen,
..
Redirecting the exhaust is not a good idea...
..
Salad oil for a lubricant - neat idea. But now the Biodiesel folks will be crying about all that vegetable oil being diverted to pneumatic cars....
..
Incidentally, because pneumatics use oil for a lubricant (incidentally with pneumatics lubrication is easy - you just insert the oil in little bits into the air intake for the motor) the exhaust contains oil. Not a lot, mind you - but enough to give you that deep fried feeling in the hot arizona sun.
..
Seriously, the reason painters don't use pneumatic sanders between paint coats is just the issue with the oil discharge. It can be that serious.
...
As for their design - I think it is really cool and fascinating. But then I like everything that shows potential - but not everything that shows potential survives the open market free enterprise system.
..
Only time will tell whether or not it takes off.
..
Back when the volkswagen beetle was first introduced (actually the Think was the original, but that was Hitler's baby, and too many people at the time associated the design with him) everyone siad it was too dinky and too ugly - but boy did it take off. the early Toyotas and Datsuns were just little dinky toy cars - but look at them now...
..
So don't take mt brass attitude to mean that I am being condescending. I am not an agruing person per se - but I love to debate an issue. And the difference between an argument and a debate is one of creativity. You argue because you disagree. You debbate to impart your views and oppinions and the result is for the greater good.
..
When I argue it is to make a point, not to degrade or defiel. If I poke fun it intended as just that - a humourous jab. My late Great Grandfather had an ultimate jab for all of us city raised folks. He was a farmer and worked with his hands. I once watched him fix a model T for his neighbor. When I alked him if he were a mechanic too - he replied. A man built this, so why can't a man figure out how to take it apart and fix it? Just because a man made something first does not mean he is the only one who can understand it!
..
This has always stuck with me. Just like my great Grandfather, Mt Granfathers, and Grand parents, and My late Dad - I am curious about everything. And I can always figure how just about anything works. The only difference between todays technology and yesturdays technology is the means to the end result. Wind pushed ships accross the seas, then Steam did it, Now diesel does it, and even nuclear power is used (but nuclear power is just another form of steam power) - so where are we going?
..
Henry Ford Built the Model T to run on Moonshine (alcohol) yet eveyone touts how Ethanol fuels are high tech. I'm a little bit amused at the ignorance that we display in regards to our past.
..
Remember - A society who ignors history - is doomed to repeat it sooner.

I paint all my own restorations and my compressor has 2 oil and water seperators on the system. One on the tank and one on my gun. This prevents what body men call Fish Eyes in the paint.
Sanders use the oil as a lubricant for the internal mechanicals and yes it is usually side discharged and should not come in contact with the prepared surface. Especially those damn Board Sanders. Can ya tell I luv 'em?
Forced air painting uses no oil in the gun and because of the seperators nearly all the oil mist which lubricates the compressor rings is removed.
I'm sure MDI could figger out a way to remove any microscopic particles of salad oil.

The air I was using for my air car came from a scuba shop. That air was intended for humans to breath so was free of oil and water contaminates. I had planed on using a scuba compressor to fill my tanks had I not decided to bail on the air project. The air MDI is putting in their car is cleaner than the stuff we breath. As I stated before. Air power has potential but not for me and my budget. I vote for the big push to be toward EVs and a continuing advancement of better batteries.

And the LiFePo chemistry is advancing as we speak. This recent round of Thunder Sky batts have added Yttrium to the anode featuring a 20C discharge and a 5000 cycle life.
Other than John Wayland's White Zombie, I don't know of any EV which might require 20C , I doubt I would draw anything close to 3C on acceleration. But then after trashing 2 couplers, I have developed a lighter foot when driving my EV.

Pretty sure that 20C discharge is a millisecond pulse rating, but yes batteries are getting better. Frankly they are almost at the point where they are technically good enough, they just need to be cheaper.

I think it will be some time before we see "cheaper".
With every downtick of the US Dollar against the Yuan, Amy Lu Sushi & freinds see their profits from US sales dwindling.

Increased production volume could continue to drive prices down, but yes a weak dollar doesn't help U.S. buyers.
