KhanAcademy.org has a pair of courses that may be useful here
[to be found under Science / Technology]:

1. Reverse Engineering (showing where some parts come from)

2. Bit-Zee Bot (uses those parts & others, incl an Arduino board)

(A Win 8 app can download these & the other courses cost-free.)

+ - Hawking boycotts HebrewU conference, against Israel's Palestinian apartheid

Submitted by Anonymous Coward
An anonymous reader writes "Stephen Hawking has brought attention to Israel's horrible treatment of the Palestinians, eg, by boycotting a conference at Hebrew University. http://www.abc.net.au/news/2013-05-09/stephen-hawking-to-boycott-israel-conference/4678414
Cf Anna Baltzer's documentary: "Life In Occupied Palestine" on hardships faced regularly by Palestinians in Israel, at: https://www.youtube.com/watch?v=lrOdCG7RrvE
I, for one, am disappointed by CBC, who, in "The Current" spent so much time asking into the ethics of such boycotts, ie, instead of investigating Israel's part in causing daily tragedies, suffered by Israeli Palestinians, or providing a link to Anna Baltzer's documentary, so people can decide for themselves whether or not to join a boycott like Hawking's."

Comment: Now, let's do similar things with Nuclear Reactors (Score 1) 180

Invest in any additional research that may be needed
to [further] prove the safety & efficacy of Thorium-based
reactors (a.k.a. "Liquid Fluoride Thorium Reactors"
or LFTRs), per Kirk Sorensen's 10-min TED-talk.

They seem to be safer than the high-pressure reactors
we use today... and they don't need or produce Plutonium.

We'll also need changes to nuclear reactor regulations,
to make it easier to build lots of small ones, closer to
where the energy (heat &/or electricity) is needed.

I'm surprised that you're not already doing this

I begin to think that the "Past-is-Future" thought-

into your psyche, making it hard to see obvious
technical solutions.. that others take for granted
(except, perhaps Yahoo's CEO.. who's recently
-forbade- her staff from enjoying the -privilege-
of telecommuting some days each week).

By all means enjoy the extra time you'll save, ie,
by telecommuting whenever you can.

Maybe even set some "new" examples:

1. telecommuting (for those who can)
2. staggered start-times (for the rest)
3. Thorium powered plant (a big job)
4. flat organisational chart
5. zero-emission company
etc.

What can you gain by -using- & -supporting-
ancient, mostly fossil-fueled, mostly self-drive

Swedes enjoyed train-commutes (through
forested areas) from Stockholm to ASEA,
sitting at desks, each with a phone, FAX &

To get-a-Life, you may need to re-think your

No solar panels => Satellites get short lives (a week or two?)

So, use 'em while their batteries last... as soon as they begin
to work. AMSAT site should have the uplink & downlink freq's
(& you should have an Amateur Radio license to transmit...)

Heavens-Above.com can tell you when to listen for the little,

Let us know what you hear... & let AMSAT know, too, if you're

So, these (& similar) Android app give audio on the event:

1. "Scanner Radio" app offers a list
- sorted by number of listeners -
of available online scanners, ie,
around USA & the world.

When I chose Boston police, fire, etc.
from that list (of course, it held top-place),
there were over 50,000 others listening-in.
Normally, numbers of listeners - across
the list - are under 500.

(If your area lacks an online-connected
scanning receiver & your have such a
receiver & some bandwidth to share,
why not consider adding your area's
emergency services audio to the list?)

2a. "TuneIn [Pro]" app is (yet another)
Internet Radio app; [Boston Univ Radio's]
WBUR stayed on the story -continuously-
from shortly after the event became known.

2b. Using the same app, one can get cur-
rent weather and detailed forecasts, also
on a continuous basis, from USA Weather
broadcasters (commercial-free, these are
available 24x7 - to those near the area of the
event - on 10 VHF channels near 162 MHz);
Boston's gov't weather station was available
via TuneIn (Search "By location" for Boston
for a list of all broadcasters - AM / FM / Wx,
including some located in nearby states).

3. "EchoLink" app - for Radio Amateurs -
let licensed Hams listen to & (in normal times)
even transmit on repeaters - most on 2m VHF
(around 146 MHz) & 70cm UHF (near 440 MHz)
- that would become active, especially when an
event (flood, earthquake, etc.) takes out normal
POTS or cellular phone & 2-way radio comms.

(If you're a Radio Ham, you can add your own
station (eg, home, office or vehicle radio) or
your club's repeater to the list. Whenever you
sign-in, you're on one of the lists, so friends
can contact you, on the fly. Also, EchoLink is
like an old-time phone-echange switchboard,
ie, able to connect repeaters, etc. together, eg,
to support relief operations after a larger dis-
aster or - during peaceful times - just a yacht-
or bike-race, etc.)

These apps work on Android phones & tab's
2.2 thru 4.1.2, in my experience. Of course,
YMMV.

I don't know what app's may be available for
iPhone, etc.

More people need to know about the opportunities of this -safer- green-

-push- for regulatory changes, that will -ease- the transition to Thorium,
in our time.

With increased safety levels, Liquid Fluoride Thorium Reactors (a.k.a. LFTRs) would have even better results.

Then, take another step: Consider the Cost-Effectiveness of LFTRs, from construction to safe storage of waste, per Mega-KWH of electricity produced.

Now, what's the best choice, out of these 3 alternatives...?
