Apparently they are getting ~70% of their lift from the buoyancy and ~30% from their propeller.

In the video included in the article, they show their prototype flying. It is surprisingly lively for a blimp (I guess owing to the fact that it gets/needs lift from the propeller), darting around in an almost fish-like fashion. I dunno, still skeptical but the video does make it seem much more plausible, at least.

This has been on here a few days ago.

I didn't want to say anything, but have been thinking about the payload. I belive it's 675 lbs.

That is not much. A truck can deliver thousands of pounds. (I have weight on my mind because I have to pick up a 800 lb mill, and bring it home in one piece.)

It might make sense in Alaska delivering small amounts of material though, but not near power lines.

This is a neat idea. I did spend the time while the page loaded wondering "wow, a service mesh to cargo airships is quite the leap" however!

Yeah I had the same confusion when the Launch thread was posted. Choosing company names is hard.

How would the moving price of Helium affect operations? Or rather, what would the range of Helium prices have to be in order to be profitable? The common trope is that "The world is running out of Helium", yet it seems like that is not actually true [1][2]. I'd be interested to hear how this is all being taken into account.

We aren’t running out of helium in the short-medium term but it’s still definitely a limited resource and there is a legitimate concern about losing access to terrestrial helium once we’ve extracted all we can. Unlike fossil fuels, helium isn’t something we can synthesize from elements that are abundant on Earth.

> Buoyant has built and flown four prototype airships. The most recent sub-scale ship that went to air is 20 feet long, with airspeeds of up to 35 miles per hour and a payload capacity of 10 pounds, but the ultimate aim is to build an airship that’s capable of delivering up to 650 pounds of cargo at a cruise speed of around 60 miles per hour.

For depot to depot delivery, how does that compare with an 18 wheeler truck with 30,000 lbs carrying capacity going down the road at 60 miles per hour?

The idea is they aren't delivering to houses directly, they're moving packages between shipping facilities. So, they can presumably having landing pads on either side that aren't near power lines.

675 pounds isn't much, but if you have a high-priority delivery that's not very heavy it might make a lot of sense. Especially in remote places; they're particularly interested in serving places that are currently served by planes and helicopters, like remote locations in Alaska.

Can a physicist help me understand something here? Assuming each of these can carry ~650lbs at 30mph. They're 60feet long and have a VERY lightweight airframe. How would these craft deal with wind? do they just get blown away every time there is a gust?

One clarification, the full-scale version's max speed is ~75 mph, and typical cruise speeds will be 50-60 mph. The 35 mph number in the article is our subscale prototype. We loose range in a headwind, but on most days the aircraft has more than enough range to complete our target missions. And on the days the weather's too bad to fly, many other small aircraft are grounded too. - Joe from Buoyant

In their Q&A thread the other day I believe they said that helium price isn't likely to impact them all that much in the short term. Maybe they'll use hydrogen at some point in the future, but it seems like they don't think it's necessary for their business model to work, given the relatively small size of their airships.

Yup, this is basically it. It's impossible to compete with a truck that's fully loaded, but there are tons of short middle mile trips where trucks aren't fully loaded (LTL or less-than-truckload freight). This type of freight is surprisingly inefficient, particularly in low density areas.

The full company name is "Buoyant Aero" for that reason! We often shorten it to Buoyant, but may use the full name more if it's a recurring point of confusion.
