I have wondered in the past if the benefits of a 'jettison damaged engine' feature would outweigh the risks.

Exactly. They are actually efficient enough to be quite competitive in the private sector. They have large contracts with Boeing, and they manufacture a wide variety of things like white boards, bac…

The Lighthouse for the Blind. I donate to their charity annually. Here is a link to a virtual tour of the facility I visited: https://www.youtube.com/watch?v=zzfCNQatw00 …

A few years back I toured a machine shop staffed primarily by blind individuals. The Javits–Wagner–O'Day Act requires federal agencies purchase some select goods made by the blind when possible.…

I've been looking for an excuse to buy the NASA Graphics Standard Manual. It looks like Standard Manual has published new books dedicated to the Worm and Bruce's work on the Bicentennial lo…

They have a live telemetry animation web app, but I am currently getting a 503 from cloudfront. https://eyes.nasa.gov/apps/mars2020/ …

To quote Nick Cage in Lord of War: Yuri Orlov : [Narrating] Of all the weapons in the vast soviet arsenal, nothing was more profitable than Avtomat Kalashnikova model of 1947. More commonly known as …

Many car manufacturers have found that it is cheaper to ship all vehicles with a feature, and then have the owner pay to unlock it. https://www.theverge.com/2020/7/2/213…

My county conservation district has a great native plant program. They have an annual native plant sale with amazing prices. I am picking up an order of 25 mock orange this weekend that I paid $10 f…

It sounds like it only has a color depth of 4096.

The new at-home screening kits look promising.

https://breathequality.com/winix-c545-review/ There are definitely better units out there, but not for $100. That was the sale price at Costco when I got mine.…

The filters I got at Costco for $100 on sale have these features too. https://imgur.com/a/ntgCwbl

They 3d print well if you have a good printer. I've seen designs that use standard size computer fans, which make them cheap and easy.

This is exactly the kind of pedantry I was trying to avoid by rounding. Fan X moves "15x more" air than fan Y. For every 1 unit of air fan X moves, Y will move 1x15 = 15 units. In the time…

It sounds like you need a ceiling fan. I have an ADU with a half loft and 26' ceiling over the other half. One decent fan really moves the air.

I've never claimed that it does not filter, just that it is a fraction as effective as the alternative at 5x the price. We heat with wood in the winter and some smoke escapes when you open the d…

Check out dyson's website. They don't even list fans on their product page. It's just variations of air purifiers. They are all advertised first and foremost as purifiers. https:&#x…

Wow, they have a payment plan for the filters. https://www.dyson.com/support/journey/tools/970341-01 …

My issue is the cost. My local costco has these units in store for $800 USD. Further down the isle they have oscillating tower fans for $30, and smart air filters for $100. I bought two pairs of eac…

I rounded up to be generous.

IIRC, this myth stems from a successful govt propaganda campaign that aimed to reduce power usage at night and put an end to rolling blackouts.

I still cannot get over this product. They whole selling point of a dyson fan is the 'air multiplier' tech, which creates a low pressure zone that propels air through the ring. According t…

Nile Red did a great video on his attempts to reproduce these results: https://youtu.be/x1H-323d838

I think that their higher tier promotion system is partly to blame, and could be easily fixed. As I understand it, at a certain management level, the most effective way to pad out your promotion pack…

I remember Beyond Egg brand mayonnaise pushing their product as a healthier cholesterol free alternative. In trying to track down those claims just now, I learned that the FDA cracked down on them be…

The A.V. Club took flak for turning all their lists into slide-shows on desktop. Their response was to tell people to adjust their browser width to force the mobile view. When you load a page, it pr…

I thought the same about reader.

The best use case I have heard is flight schools. Last time I quoted lessons, half the cost was the fuel.

By those calculations, todays launch could have brought 15600 cubesats to orbit.
