Comment: Mars has no magnetosphere (Score 1) 496

While I fully agree we could make this place a Star Trek-like utopian society (a la The Economics of Star Trek), the point is that no matter how seaworthy you make a ship, it can still be sunk. The Earth could still suffer an extinction event that we can't prevent. Mars is really our best Plan B. We have to get in more boats to make sure we stay afloat as a species.

Mars is the easiest of the options. The others - the moon (too little gravity, can never be terraformed), a giant space station (extremely large structure required to contain 1 million humans), Venus (cloud cities perhaps), Jovian satellites (radiation, extreme cold) are tougher options.

From TFA:

Io’s ionosphere interacts with Jupiter’s magnetosphere, a layer of charged plasma that protects the planet from radiation, to create a frictional current that causes radio wave emissions.

Much like our magnetosphere on Earth protects us from radiation so too can that of a moon with an atmosphere and molten core. Mars doesn't have one and thus is hard-hit by solar radiation.

Your statement is accurate if you are talking about Earth's moon, but not correct in other cases.

+ - Exomoon Detection Technique Greatly Expands List of Potential Habitable Systems

Submitted by Luminary Crush
Luminary Crush (109477) writes "Most of the detected exoplanets thus far have been gas giants which aren't great candidates for life as we know it. However, many of those planets are in fact in the star's habitable zone and could have moons with conditions more favorable. Until now, methods to detect the moons of such gas giants have been elusive, but researchers at the University of Texas, Arlington have discovered a way to detect the interaction of a moon's ionosphere with the parent gas giant from studies of Jupiter's moon Io. The search for 'Pandora' has begun."

Luminary Crush (109477) writes "A Japanese company, Power Japan Plus, has announced plans to put into mass production a carbon-carbon ("dual carbon") battery later this year. Developed jointly with Kyushu University, the new battery has high energy density, is very safe and reliable, can sustain 3000 charge cycles, and is environmentally sustainable. If dual carbon batteries were installed in a Nissan Leaf the car could be completely charged in 12 minutes."

+ - Fusion power by 2020? Researchers say yes and turn to crowdfunding. 1

Submitted by Luminary Crush
Luminary Crush (109477) writes "To date, the bulk of fusion research has been channelled towards a plasma containment and stabilization method. This is the approach used by ITER's tokamak reactor, the cost of which could exceed US$13.7 billion before it's online in the year 2027 (barring further delays). Researchers at LPP Fusion, in a project partially financed by NASA-JPL, are working in a different direction: focus fusion, which focuses the plasma in a very small area to produce fusion and an ion beam which could then be harnessed to produce electricity. It small enough to fit in a shipping container, can double as a rocket engine, and would cost US$50 million to produce the working 5 MW prototype. To reach the next hurdle and demonstrate feasibility, LPP Fusion has started an Indiegogo campaign to raise $200K."

Researchers have found evidence for a landmass that would have existed between 2,000 and 85 million years ago.

This potentially places the landmass above sea level during a time when humanity could have been present on it.

It's from Wyse, so it's basically a "thin client". Don't get me wrong, Wyse makes good thin clients, but it's not fundamentally different than anything out there already. It's basically a way to run "VDI" (Virtual Desktop Interface) from your pocket.

OK, cool enough, but I can already do that with an app on my smart phone. I can run a plethora of thin client software - Citrix, VMware, Webex, PCAnywhere, Microsoft RDP, VNC... what else? The only unique thing I see here is that you can attach to a larger external screen. With an iPhone you can do that via an Apple TV with mirroring. The experience isn't fantastic but it's only a matter of time for that architecture to improve (same with Android equivalents).

I do not see myself carrying yet another device. I could see myself using my phone this way if the external graphics worked better - and there is nothing technically stopping that from happening now.

Apple or Google/Android could blink and destroy the market for this device.

All material science and concentrator advances of the last 10 years seem like small refinements in comparison. Is this the breakthrough we've all been waiting for, or is it just another technological let down waiting to happen?

Pretty cool. The ship was locked up though, so I only got to check out the outside. It's bigger than you'd think.

Sea Shadow in the floating dock

From what I understand they tried to find a museum for the ship but there were no takers. The dock was in rusty/poor condition, but the ship looked garage-kept ;-)
