Navy Bomb Squads Get a Solar Power Upgrade
An anonymous reader sends this excerpt from TPM's Idea Lab:
"The U.S. Navy's bomb squads have a weight problem. To keep their field gear powered up, the typical explosive ordnance disposal unit has to haul fifty pounds of specialized chargers and related devices around, creating an unwieldy and potentially dangerous drag on the operation. Now help is coming from an unexpected source: the sun. The Navy's Explosive Ordnance Disposal Training and Evaluation Unit 2 in Virginia has been testing five prototype lightweight field power kits that include solar cells as a key component. The kits replace fifty pounds of equipment with a compact system that weighs only about nine pounds."
I've been told repeatedly that alternative energy is just a Liberal tree-hugging pipe dream that destroys jobs and wastes money! Now you're telling me that we can wage more effective war by using solar energy? Well, consider my mind blown. Vote Republican! 'Cause anything else is treason!
They only disarm bombs during the day time and weather permitting...

Id love to know what kind and how efficient these solar panels are to power all this high tech gear with only 9lbs worth of panels, power regulators, and possibly some batteries. you'd prob be lucky to power a netbook of 9lbs of off the shelf solar panels, and youd better hope there are no clouds
TFA isn't any more specific on what "specialized chargers and related devices" are, that would weigh the difference of 40 pounds. Were they hauling ABS's or car batteries around? I could fill a shopping bag with chargers and it still wouldn't weigh more than a few pounds.
50 "lbs" is about 25kg. Quite why that should be considered such a problem, I don't know.
I want to live a life of danger !! Haha, just kidding !!
it's not just defense where you have a mess of charges and batteries.
It's
Phones
EXT HDD's
some displays
AV stuff
USB hubs
dsl and cable modems
routers
switch's
web cams
and a lot more stuff.
I'm sure the smart folks already thought of this, but what happens when the sun isn't around? Aren't you going to have to have that 50 lbs of material sitting around just in case?
Also, I'm guessing to lessen the problems of night or days with no sun, they're going to have to be carrying around some batteries. Batteries aren't the lightest thing to be dragging around.
Not to mention, aren't we talking about bombs that weigh from several hundred to several thousand pounds? Does the fifty they're already carrying around make that much of a difference?
Ooohhhhh... these are the guys that blow up the bombs (Explosive Ordnance Disposal), not the guys who are responsible for the care of _our_ bombs. I guess I can see lugging around a diesel generator might not be much fun, but that would be better than having only your fancy solar array when the clouds coming rolling in. Of course, you can be lugging around a few hundred pounds of batteries to make sure you have a few hours of reliable power, but what's the gain?
Oh well, hurray for research!!!
They only disarm bombs during the day time and weather permitting...
Given that its *Navy* EOD you might want to add only bombs that are on land or at the surface. :-)
It seems they got the bulk of the weight reduction not by replacing each particular charger with an equivalent solar unit, but replacing all the chargers with a single solar unit with a unified distribution system. The solar thing is just the buzzword to make people talk about it. Portable solar is much less weight-efficient than say, Li-Poly batteries or AC adapter units.
It would seem just as easy and probably cheaper to use a regular high power charger with that same unified distribution system. Like replacing the half dozen or so wall chargers by my desk with a single charger that's just slightly bigger than one unit, plus multiple cables for the devices.
I suppose most of the use for this type of stuff is the middle east, which has a lot of sunshine anyway... I'm surprised they're not standardized on a single type of power. Hell, use a USB charger for everything.
Guys, you're missing the point.
...) This unit can accept power from a lot of different kinds of sources (conventional grid AC, but also DC etc.), they plan to also distribute a set solar cells and buffer batteries, that can (naturally) also plug into this unit - but will almost double the weight of the equipment to about 17lbs. (Still a lot less than 50 lbs, but the usual caveats of solar power apply, so they are quite likely to end up using other sources a lot as well.)
The weight savings result from doing away with a mess of redundant equipment/chargers etc. that were designed by moronic, egoistic engineers whose idea of standardization is that they are happy to follow any standard, so long as it's theirs.
They were instead replaced by one small and much more lightweight unit that weighs 9lbs instead of 50lbs and is still able to plug into all their gadgets and charge their batteries. (Maybe one day we can do that with laptops and cellphones too
I've got a great idea for saving money and lives.

Here in reality, many people are successfully building out solar power systems using components built in the USA or Europe using green energy.

This terrible loss of life could have been prevented...if only the sun had come out soon.

"Brittle Power: Energy Strategy for National Security is a 1982 book by Amory B. Lovins and L. Hunter Lovins, prepared originally as a Pentagon study, and re-released in 2001 following the September 11 attacks. The book argues that U.S. domestic energy infrastructure is very vulnerable to disruption, by accident or malice, often even more so than imported oil. According to the authors, a resilient energy system is feasible, costs less, works better, is favoured in the market, but is rejected by U.S. policy. In the preface to the 2001 edition, Lovins explains that these themes are still very current."
Reading a lot about that, it seems that renewables have been cheaper than fossil fuels and nuclear since the 1970s if externalities are accounted for (including pollution, disease, defense, corruption, other risk). The difference is that now, through decades of hard work by dedicated researchers, renewable are now becoming cheaper even when not accounting for externalities.

""Solar power may be cheaper than electricity generated by fossil fuels and nuclear reactors within three to five years because of innovations, said Mark M. Little, the global research director for General Electric Co. (GE)," Bloomberg reports."

Compressed air, thermal storage in molten salts, and pumping water are all workable solutions for storing power, as are improving batteries and hydrogen production. There are solutions. The big issue is that we don't make coal, oil, natural gas, and nuclear pay the true cost for pollution costs, health damage, defense costs, climate change, or meltdown risk.
So, for example, I can't eat fish caught locally in the North East US because of mercury pollution from coal burning power plants in the Midwest US. So, I've lost something valuable, for what in exchange? US Republicanism in practice is the worst sort of socialism -- privatizing gains but socializing costs (not to say US Democrats are often that much better). Thirty years of this worst sort of socialism has done a lot of damage to the USA (might as well have real "socialism" instead, IMHO, because it is hard to imagine everyone having medical care and free college and reliable infrastructure would make things worse at this point):

Not to say we were not warned, like by Jimmy Carter:
http://www.pbs.org/wgbh/americanexperience/features/primary-resources/carter-crisis/
"We are at a turning point in our history. There are two paths to choose. One is a path I've warned about tonight, the path that leads to fragmentation and self-interest. Down that road lies a mistaken idea of freedom, the right to grasp for ourselves some advantage over others. That path would be one of constant conflict between narrow interests ending in chaos and immobility. It is a certain route to failure. All the traditions of our past, all the lessons of our heritage, all the promises of our future point to another path, the path of common purpose and the restoration of American values. That path leads to true freedom for our nation and ourselves. We can take the first steps down that path as we begin to solve our energy problem."
