marvin the martian raygun air conditioning
Buses are airflow sloths, So i designed an airflow gun to help get high pressure clean air into the sojourning device interior; also known as bus interior by many. this worked so well that i had to don a light jacket and put one over my legs to stay warm on a recent night trip (5-1-16) the frontal area is a 6"x 12 " register duct (72 square inches) flowing into a 6" x 24" sheet metal duct and then into a 4" pvc. clean out sweep and then into a pvc. 22 degree street ell. high flow high pressure air by such an unusual device i nicknamed it marvin the martian ray gun a.c. The most awesome images on the Internet

Is that for use while in motion?

cadillackid 05-08-2016 06:00 AM

that will bring some air in... and the bugs and the rain too

I wouldn't want to behind you when that thing comes off. :popcorn:

that is quite the contraption! man i really hope my family never has to drive behind you though, perhaps a LOT more securing is in order. when , not if, that thing flies off pray that it doesn't hurt anyone!:eek:

the idea is sound though. need different materials, maybe hood scoop off old hot rod would work safer and better, or something that shape. then you could put cover on it and be able to open and close it from the inside. maybe even be able to swivel it to not be a water grabber when raining.

That was my thinking.

My old Ford shorty just has a simple air scoop on the side with a flap to block it off. If you've ever driven through bees on the highway you'll be glad you can close the scoop.

HAHAH, that is great! I'm dying laughing. You really need to secure that thing WAY more.
But The idea of moving air around in there is a good one. I like the hood scoop idea, or maybe one of those fresh air vents you see on enclosed trailers, but make it swivel like jester said.

Robin97396 05-09-2016 12:07 AM

It would be nice if the vent could be adjusted from inside so it would either blow fresh air while facing forward, or draw air out by facing backward.

It does look... intimidating. Like a giant vacuum cleaner with an itty bitty intake racing down the road, slurping up.. whatever things dwell at 9 ft above the pavement.

How about an RV roof vent cover turned to face the "wrong" way so it's an air scoop instead?

years ago a group of us were on a trip in an old Land-rover somewhere in arizona.. We tossed the A/C belt somewhere along the way.. the people in the back seat hated us opening the windows.. but below the windshield it had these vents that popped open.. they had screens in them to catch any debris..

yeah the screens Worked when we hit that mob of bugs.. some kind of bees or flies.. the screens caught the BUGS but the 2 of us in the front seat got our faces sprayed with bug GUTS!!

the next town we found we hit the Local truck stop then Napa to buy a socket set and an A/C belt!!

With 4 big round holes already there...the fauxaldiyraygunmailboxsewervent...didn't need to be built :biggrin:

kind of looks like a humming bird feeder or old Motorola player, depending on paint choice, why OP? is it just a code when you where bored?

If not I apologize and add that would get you pulled over in a lot of locales

I'm not much of a fan of what you have here for all the reasons others have mentioned. I can't tell from your avatar, but you should have a fresh air supply on your bus controlled by a knob by the driver. The exterior vent for that is here circled in red

If you don't have that, I would think you should still have some sort of external air source to come out of the vents.

Mega maid!

what is illegal or unlawful about the air vent? is unconventional against the law or codes? provide evidence and not opinion.

tincaneasybakeoven 05-11-2016 01:23 AM

fresh air opening is flat, on the side, by small louvers in a no pressure zone and provides near zero airflow. when boundary layer air adhesion is lost the flow becomes negative. the air scoop survived a 280 mile trip without movement as configured so the detractors would have followed from driveway to driveway without event.
just sayin..........

Think it would stay on in one of those Texas Tornadoes you guys are famous for??? ;-)

tincaneasybakeoven 05-11-2016 05:16 AM

yea everybody missed the 6" screw band clamp on the front near the register box sheet metal. but yet they trust pressurized air oil and water to the same screw band clamps. very "dual minded" imo.

jester 05-11-2016 07:24 AM

no one was trying to offend you. it just plain physics, you have a bunch of plastic and sheet metal bailing wired to the windy roof of a school bus traveling fast. pipe clamp or not man that just not safe. i can pull a sheet metal screw out so i know the wind can. i think if you just put a plumbing sweep out any of the windows on side of bus you would have same result with half the risk of hurting someone. besides its the people behind you that you are putting in harms way, not you, doesn't that worry you?? and you really dont think the police are going to pull you over for it??
all the air oil and water that is clamped is to the frame or thick steel and WAY out of the wind, or path in which something, anything, can hit it or damage it. like i said , think of the people behind you on the road.

by the way i liked the ingenuity of it and just suggested safer materials.
