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. 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. 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.
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.
