I've never seen the other two, but Hank Green, and his brother John, are two people who've earned much respect in my view, for their charity work, for their educational series "Crash Course", and for the work they've done supporting other youtube science channels, like Emily Graslie and Animal Wonders.
Latency isn't too bad from LEO. Existing satellite systems work from geosync, which is worse. Some of the advantage will be eaten up by routing, and bandwidth will probably be pretty limiting. I'm interested in seeing how they solve the routing problem.
All these things make me worry about Kessler Syndrome. Maybe we need some kind of international LEO traffic control body, to regulate and assign safe orbits, track junk, and whatnot.
The IRS hasn't really been enforcing that rule.
You see the same thing whenever feminism comes up. Another reliable way to bring out the morons is anything like "Hey, guys, rape is bad and people who do it are bad people."
In a two-body system.
The delta-V budget to reach LEO is staggering, if you've played KSP a lot. You can pretty easily get 10-15% payloads to orbit around Kerbin, but Earth payloads are more like 3-5% at best.
I'm a little offended that they chose Remembrance Day for their shopping extravaganza.
I work at a library, and Adobe's log server has been in our firewall for a while now. It's a violation so blatant that it actually went up a few layers of management for a change.
Richard Stallman is playing the world's tiniest violin somewhere right now.
Where the cost of shipping is prohibitive - the Canadian Arctic, say - mass production might not even come out ahead.
It's a partial solution. Hydro power is only really available in certain areas, and transmission losses kill some of the gains. BC makes a good amount of money this way. North America's hydro capacity is probably as large as it will ever be, because it's extremely destructive of wildlife habitat and of arable land.
