There are several much simpler ways a robot car could
connect itself for charging
That's a bold assertion. What's your suggestion that would be simpler than a cable driven arm like in the OP? A couple linear actuators in the base, no precision bearings. 1 of 9 results (But it would be nice if the next-gen solar panels
installed on a car would be efficient enough to provide
enough power for a car drive)
You only get about 1.5KW of light per square metre, on average. A car has maybe 4-8 square metres of usable solar panel space, so guess you could get 3-6KW of power using superexpensive cutting-edge 3-junction solar panels that manage 50% efficiency.Model S has a 310KW motor. Assume you only run it at 10% of rated power when cruising, and that's 31KW of power draw. More than that, of course, since the motor controller won't be perfectly efficient.
No way you can run a consumer vehicle on solar panels built into the body.
Generally, the big risk with elevated freshwater lakes connected to the sea by locks isn't saltwater contamination, but the disastrous flood that would happen if all the lock gates were opened at the same time. A lot of work was put into the safety measures, most of which have been removed due to cost in recent decades: https://en.wikipedia.org/wiki/Panama_Canal_locks#Safety_feat...
If a flight of locks was completely opened, Gatún would promptly drain out of them, wiping out everything downstream. You could imagine the entire canal would be offline for months to years as infrastructure was rebuilt and the lake was refilled by rainwater.
In 2006, Tor research was funded was through a no-bid
federal contract awarded to Dingledine’s consulting
company, Moria Labs. And starting in 2007, the Pentagon
cash came directly through the Tor Project itself —
thanks to the fact that Team Tor finally left EFF and
registered its own independent 501(c)(3) non-profit.
How dependent was — and is — Tor on support from
federal government agencies like the Pentagon?
In 2007, it appears that all of Tor’s funding came from
the federal government via two grants. A quarter million
came from the International Broadcasting Bureau (IBB), a
CIA spinoff that now operates under the Broadcasting Board
of Governors. IBB runs Voice of America and Radio Marti, a
propaganda outfit aimed at subverting Cuba’s communist
regime. The CIA supposedly cut IBB financing in the 1970s
after its ties to Cold War propaganda arms like Radio Free
Europe were exposed.
The second chunk of cash — just under $100,000 — came
from Internews, an NGO aimed at funding and training
dissident and activists abroad. Tor’s subsequent tax
filings show that grants from Internews were in fact
conduits for “pass through” grants from the US State
Department.Can it produce 3D footage, I wonder? Intuitively, it feels like 360-degree 3D video would require a heck of a lot of cameras.
The specs aren’t listed on the FDK site but the safety
data sheet shows it is a 3V battery although amperage is
unclear.
All lithium-ion batteries have a nominal voltage of 3.7V, like how all alkaline batteries have a nominal voltage of 1.5V. It's just how the chemistry works.(Actual voltage can vary quite a bit, depending on where you are in the discharge curve: http://i.stack.imgur.com/UkodS.gif)
And to be somewhat needlessly pedantic: you want "amp-hours" there, not "amperage". Amp-hours is the unit of capacity, amps is how much current is being drawn at that very moment. In the automotive metaphor, amp-hours (or watt-hours) is how big the gas tank is, while amperage is engine horsepower.
Page 62: Mildly surprised that they don't want crimped connections soldered, but I suppose that compromises flexibility, and shouldn't add all that much strength if they're properly crimped.
Page 76: Wow, had never heard of "connector saver" jumpers before. Sounds bananas, but I suppose if you're going to test everything ten times for every launch, it's mostly reasonable.
The fileserver tier consists of pairs of Dell R720s
running in active/standby configuration. Each pair is
largely similar to the single pair of machines that the
old Pages infrastructure ran on.
