Portable Air Conditioners – Why you shouldn’t like them…

01) Portable Air Conditioners – Why you shouldn’t like them


“Seriously, either we need to get more awareness of how dumb single-hose portable A/C units are, or we need to just use window units whenever possible. While I know that there are times a portable unit is the only option (remember, I’m in that boat), it seems that only very high capacity, premium machines have the facility to use two hoses. Which is frankly stupid but then again that’s what I’m trying to tell you now.”

01) Why Machines That Bend Are Better


“I visited the Compliant Mechanisms Research group at Brigham Young University and spoke to Professor Larry Howell:

https://www.compliantmechanisms.byu.edu

At the above link, you can download 3D-print files to make some of the objects in the video, plus learn more about compliant mechanisms.

What I learned about compliant mechanisms I summarize in the 8 P’s of compliant mechanisms:

1. Part count (reduced by having flexible parts instead of springs, hinges)

2. Productions processes (many, new, different enabled by compliant designs)

3. Price (reduced by fewer parts and different production processes)

4. Precise Motion (no backlash, less wear, friction)

5. Performance (no outgassing, doesn’t require lubricant)

6. Proportions (reduced through different production processes)

7. Portability (lightweight due to simpler, reduced part count designs)

8. Predictability (devices are reliable over a long period of time) “

01) EHANG 184 Autonomous Aerial Vehicle (AAV)

“Ehang 184 AAV is the safest, Smartest and Eco-Friendly low altitude autonomous aerial vehicle, aiming on providing Medium-Short Distance communication and transportation solution.

The 184 AAV is designed with full redundancy – If one set of the power system are operating abnormal, the vehicle can still operate a normal flight plan and ensure the safety of the passenger together with the vehicle.

The 184 was designed to be a 100% with green technology, and is powered by electricity only.”

02) The Ehang 184 personal drone is ready to fly [2017]

“Last year the Ehang 184 autonomous aerial vehicle (AAV)—what we might call a big-ass drone—was a prototype. This year it’s a real, flying vehicle, seasoned by 200-plus successful (non-crashing) test flights, and it just may start taking passengers for real in the near future.”

03) Ehang 184 Human-carrying Drone [2016]


“Anyone want to “E(hang)” out in the sky? This human-carrying drone will enable you to do that. It’s called the EHang 184, made in China and raised around $50M to date. It can also fly autonomously. Would you take a ride?

01) How this Radical Car Missed its Chance to Change the World


“The story of Elio Motors has been a tumultuous one. This upstart car company has had a tough go of it, with funding, engine and other issues that have caused them to delay their car year after year. But is there some light at the end of the tunnel for Elio?”
