Length: 100,000km, anchored on the Earth with a large mass floating in the ocean and a large counterweight at the top end, called an Apex Anchor.
Width: One meter
Design: Woven with multiple strands to absorb localized damage and curved to ensure edge-on small size hits do not sever the tether.
External Power: The power must be external as the gravity well is extreme and lifting your own power is a non-starter.
Dr. Edwards’ approach was to use large lasers pointing up to the climber with a “solar panel like” receiver on its nadir position.
Cargo: The first few years will enable 20ton payloads without humans [radiation tolerance an issue for the two week trip] with five concurrent payloads on the tether for the two-week trip to GEO. [Currently, the plan is seven concurrent payloads for one-week travel.]

What could possibly go right?

A submarine landslide might release a Gigaton of carbon as methane (Archer, 2007), but the radiative effect of that would be small, about equal in magnitude (but opposite in sign) to the radiative forcing from a volcanic eruption.

That cherry.
Let's talk about the effect on climate change of the release of tens of thousands times more CH4 than a hypothetical submarine landslides.

...what is the Equilibrium Climate Sensitivity? That's the Billion dollar question...

E X A C T L Y

Now why are we crying about a meagre $1B to get that answer?

Re the " Apocalyptic Global Warmists ":, we are more concerned with methane tipping points
(you know, when we burn enough carbon to warm the oceans and atmosphere so the TRILLIONS of tons of
methane in permafrost and in undersea clathrate deposits are emitted). That promises runaway climate change.

There is no scientific consensus on what should be done about global warming.

The commonly accepted way to reduce climate change (archaic form: global warming) is to reduce emissions of greenhouse gasses (GHG).
The largest sources of human caused GHG emissions are a. coal fired electricity generation b. industrial agriculture.
The total CO2 equivalent emitted by you, me and what we consume, every year is 30 Billion tons.
That needs to be reduced by at least 50% within two decades or so.

Coal fired electricity generation produces prodigious amounts of CO2.
The problem with reducing coal based emissions is many fold:
on one side are entrenched interests in coal mining, and built infrastructure, that influence politics and public opinion.
Renewables were once very expensive but are competitive now. The mass production of PV panels shows what can be achieved.
The Germans have done a great deal of research to evolve technology solutions to maintain modern lifestyles.

Industrial agriculture produces prodigious amounts of CH4 (aka methane).
The waste of up-converting feed stock into live stock will be reduced by increasingly poorer climate conditions.
Since the ratio of petrochemical energy in to food energy out is something like 10:1 all food will get expensive
as fuel costs keep rising with the inexorable increased cost of oil exploitation (aka peak oil).

Obama's $1B will fund a lot of US research to help you maintain your life without ruining the earth's ecological systems

Comment Because GAY Marriage (Score 1) 279

It's not global warming, at least not caused by our burning BILLIONS of tones of fossil fuels.
Simply, it's all God's fault for being such a homophobic sociopathetic but supreme being

A UKIP councillor has blamed the recent storms and heavy floods across Britain on the Government's decision to legalise gay marriage.
David Silvester said the Prime Minister had acted "arrogantly against the Gospel".

I LOVE A SUNBURNT COUNTRY
(with apologies to Dorothea Mackellar)

I love a sunburnt country
A land of sunburnt plains,
Of sunburnt mountain ranges,
Of droughts and sunburnt rains.
I love sunburnt horizons
I love her sunburnt sea
Her sunburn and her sunburn
This sunburnt land for me.

Micheal Leunig, 16 December 2006

Yup; Australia has never been hotter / dryer / more sunburnt ...

Comment LEAF Multiple Battery Size Options (Score 1) 810

A common complaint about the all-electric Nissan LEAF has been its short range, officially 75 miles on a full charge according to the U.S. Environmental Protection Agency. To address that challenge, Nissan could add options for consumers to purchase bigger battery packs to boost the LEAF’s all-electric range, Pierre Loing, vice president of product and advanced planning and strategy told PluginCars.com. “The packaging easiness (of the battery) makes it easier to put more batteries in the car, and you will see this,” Loing said during an interview this week at the 2013 Los Angeles Auto Show.

EV range is such a hard problem, unless you think about it.

Comment US military open-air burn pits (Score 1) 1143

Something the EPA should look at is huge health (bill) implication for veterans exposed to dense acrid smoke from open-air burn pits on military bases in Iraq and Afghanistan.
This is a seriously appalling way to run garbage disposal: 10 acre open pit fires going 24/7 burning all camp waste.
