i would like to ask:-
"what is the problem in present design so that we can have a capsule that can accomodate just people"
there is vaccum in tunnel we can have even a bigger capsule
plz answer in basic terms as i am just a graduate student
Sounds really cool. I had read about this sort of concept. And a less credible idea, but intriguing anyway, drilling straight down through the earth to the other side, and using only gravity to provide the needed acceleration and deceleration.
Comment: 1g refers to acceleration rather than force. It's 9.8 meters/sec/sec, or 32 ft/sec/sec. It should take just over 3 minutes of constant 1g acceleration to reach 4000 mph (=5867 ft/sec), from a standing start.
The force required to achieve that depends on the mass of these capsules.
I would think that any small shift in the soil surrounding these tunnels would, uuh, really spoil your day, if you're a passenger.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
