New personal record altitude with tethered solar balloon
I designed and built a new solar balloon model (see my threads in the FF section or my website www.solar-balloons.com if you don't know what I'm talking about). It's a giant version of my drawstring balloon called the "EZ tube".
This new balloon inflates in seconds just by forcing air into the wide open mouth, then the drawstring is used to close it and it heats up and flies within a minute. I made this big one specifically for AP, and on its first day of flying, I got my best aerial pics yet....
Video of the balloon coming soon, it will be on my site soon as well.
ps - all images are 1024x768 for desktop backgrounds, if you're using that resolution

Hi catman, Cool!
How big is this one and how much weight is it carrying? I would guess carrying 12 oz is pretty hard to do?
Seems like it might be a cheap way to do aerial panoramas without having to buy and store helium.

If it doesn't carry 12 oz, I have several other designs, my biggest will carry 2+ lbs. it's all on my site. this one is 15 ft long x 5 ft diameter, and my camera is about 6 oz w/ batteries and was taken up pretty fast once the balloon was full and hot

Whatís the lowest outside temperature you have flown at?
Up here in the, Great White North, Ah,
Itís going to be 30 and sunny this weekend, and I thought it may be a good project.
Have you tried to boost the heating? How hot does it need to be inside the balloon?
|Jan 04, 2008, 05:26 PM|
I don't have the instructions yet on my site for a giant EZ tube, which I used here, but it's just like the regular EZ tube, except with 15 bags, 5 across and 3 down. I'd say the EZ tube is the best because you don't need a fan or any power source to inflate it, and it's very easy to deflate.

Has anyone used car exhaust?
Have you or anyone tried inflating a balloon with car exhaust?
It might sound funny, but I figure I have a car with me on these aerial jobs, and the car exhaust is already nice and hot.
But the only downside would be that CO2 is heavier than air, and perhaps the steam (H2O) would condense on the balloon walls.
EDIT: I remember my old Volkswagen ('73 Beetle) had a exhaust-powered heater; basically a heat exchanger attached to the exhaust pipe so you get hot air without the exhaust. But I realize, a cheapo $200 generator and a electric hairdryer might do the trick...
Do you know if anyone has actually tried it?

I tip my hat to you! Very well done. Years ago, when I was about 18, some of the guys took a large trash sack and put some soda straws across the mouth and put a small pie pan, I believe on it and put some cotton in there and soaked them with some kind of alcohol and lit it, and this was done at night with no wind to speak of, and it went up about 30 to 50 feet and any little breeze made the flame get a little bigger. We heard that there were several calls into the police that there were UFO's out there.
|Jan 04, 2008, 07:10 PM|
I have always wanted to do a birthday candle/alchohol balloon, but I've always been afraid the plastic would catch fire. I know lots of people do it safely but I would be a little nervous anyway. I've heard they make great UFO's and that's one reason I would like to do it.

Catman, very clever use of the technology, but nowhere on your website did I see anything regarding official permission for free flying balloons in public airspace. How do you get clearance from FAA for your flights?
|Jan 05, 2008, 11:18 AM|
If you don't mind me asking, can you give us an idea of how much money we can make having Google Ads on informational websites like yours? (http://www.solar-balloons.com)
I've been thinking about setting up sites like that, and thought it's nice residual income. C'mon, just a tiny, little hint...
I was thinking of making a beginner RC website.

Subpart D - Unmanned Free Balloons
Source: Docket No. 1457, Amdt. 101-1, 29 FR 47, Jan. 3, 1964, unless
This subpart applies to the operation of unmanned free balloons.
However, a person operating an unmanned free balloon within a
restricted area must comply only with 101.33 (d) and (e) and with any
additional limitations that are imposed by the using or controlling
agency, as appropriate.
101.33 Operating limitations.
No person may operate an unmanned free balloon-
(a) Unless otherwise authorized by ATC, in a control zone below
2,000 feet above the surface, or in an airport traffic area;
(b) At any altitude where there are clouds or obscuring phenomena
of more than five-tenths coverage;
(c) At any altitude below 60,000 feet standard pressure altitude
where the horizontal visibility is less than five miles;
(d) During the first 1,000 feet of ascent, over a congested area of
a city, town, or settlement or an open-air assembly of persons not
associated with the operation; or
(e) In such a manner that impact of the balloon, or part thereof
including its payload, with the surface creates a hazard to persons
or property not associated with the operation.
(Doc. No. 1457, 29 FR 47, Jan. 3, 1964, as amended by Amdt. 101-5, 56
FR 65662, Dec. 17, 1991)
101.35 Equipment and marking requirements.
(a) No person may operate an unmanned free balloon unless-
(1) It is equipped with at least two payload cut-down systems or
devices that operate independently of each other;
(2) At least two methods, systems, devices, or combinations
thereof, that function independently of each other, are employed
for terminating the flight of the balloon envelope; and
(3) The balloon envelope is equipped with a radar reflective
device(s) or material that will present an echo to surface radar
operating in the 200 MHz to 2700 MHz frequency range.
The operator shall activate the appropriate devices required by
paragraphs (a) (1) and (2) of this section when weather conditions
are less than those prescribed for operation under this subpart, or
if a malfunction or any other reason makes the further operation
hazardous to other air traffic or to persons and property on the
(b) No person may operate an unmanned free balloon below 60,000
feet standard pressure altitude between sunset and sunrise (as
corrected to the altitude of operation) unless the balloon and its
attachments and payload, whether or not they become separated
during the operation, are equipped with lights that are visible for
at least 5 miles and have a flash frequency of at least 40, and not
more than 100, cycles per minute.
(c) No person may operate an unmanned free balloon that is equipped
with a trailing antenna that requires an impact force of more than
50 pounds to break it at any point, unless the antenna has colored
pennants or streamers that are attached at not more than 50 foot
intervals and that are visible for at least one mile.
(d) No person may operate between sunrise and sunset an unmanned
free balloon that is equipped with a suspension device (other than
a highly conspicuously colored open parachute) more than 50 feet
along, unless the suspension device is colored in alternate bands
of high conspicuity colors or has colored pennants or streamers
attached which are visible for at least one mile.

(8) The forecast time and location of impact with the surface of
(b) For solar or cosmic disturbance investigations involving a
critical time element, the information in paragraph (a) of this
section shall be given within 30 minutes to 24 hours before
beginning the operation.
(c) Cancellation notice : If the operation is canceled, the person
who intended to conduct the operation shall immediately notify the
nearest FAA ATC facility.
(d) Launch notice : Each person operating an unmanned free balloon
shall notify the nearest FAA or military ATC facility of the launch

(1) Unless ATC requires otherwise, monitor the course of the
balloon and record its position at least every two hours; and
(2) Forward any balloon position reports requested by ATC.
(b) One hour before beginning descent, each person operating an
unmanned free balloon shall forward to the nearest FAA ATC facility

shall include the last recorded position and any revision of the
forecast trajectory. The nearest FAA ATC facility shall be notified
immediately when tracking of the balloon is re-established.

nearest FAA ATC facility when the operation is ended.
I was just wondering what you guys thought of these-they make it sound like a big hassle to lets these things go :P Dont get me wrong I want to do it it sounds fun but idk with all these rules...... Just wondering what you guys think
