Voyager Leaves The Solar System – What an amazing and historic time

Posted on by

I am 57 years old and it may all be down hill from here. Seriously. In humankind’s 100,000 year history we just threw a spear out of here. In terms of what we were promised – you know warp drive, aliens and foreign civilizations it is kind of drab; but in terms of goal posts, it is a huge leap. Some might even say a quantum leap. All I can say is WOW.

More evidence that Voyager has exited the solar system

Friday, October 5, 2012

A science blog with Eric Berger

Something very, very interesting is happening with Voyager 1, the human probe that’s the very farthest from Earth.

New data from the spacecraft, which I will discuss below, indicate Voyager 1 may have exited the solar system for good. If true, this would mark a truly historic moment for the human race — sending a spacecraft beyond the edge of our home solar system.

At last check, NASA scientists said they were not yet ready to officially declare that Voyager 1 had officially exited the solar system by crossing the heliopause.

To cross this boundary scientists say they would need to observe three things:

1. An increase in high-energy cosmic rays originating from outside our solar system

2. A drop in charged particles emanating from the sun.

3. A change in the direction of the magnetic field.

As I reported in June,  in regard to the first point, scientists have observed a sustained increase in galactic cosmic rays during recent months.

This is so cool that I really don’t know how to describe it. Lights that use 6 watts of energy and are controlled by your telephone. The future is here.

LIFX bulb shines light on connected home vs gadgets

Who needs a light switch when you have smart bulbs paired with smartphones? LIFX is just that: a Wi-Fi connected LED bulb that you remotely control or even change the color. But will consumers want one-off connected gadgets or centrally-managed smart homes in the future?

A new Kickstarter project aims to offer Wi-Fi connected light bulbs to the masses and the best part is, you can change the bulb’s color with the help of a smartphone. The bulb is called LIFX and thanks to the LED technology inside, it’s an energy saver when compared to traditional or CFL bulbs. You control the brightness and color directly from an iPhone or Android device using the LIFX application and there’s smarts in the bulb itself: It can notify you when a new Twitter message arrives, for example.

Take a look at the LIFX explanation video and you can see that the creators my be correct in calling LIFX the “smartest light bulb ever made”:

(No video included because I do not have the skills but please go there and look at it.)

The project impresses me for a few reasons. LIFX, which can be backed for as low as $69 a bulb, has already surpassed its $100,000 goal for backing, taking in over three times that much with nearly two months left for fundraising. It also brings a wide variety of functionality to something most people consider mundane but necessary: a light bulb. And it appears simple to use through the dedicated smartphone application or can still be turned on or off through the existing light switch.

Don’t Let Bayer Kill Off The Honey Bees – Contact the EPA

Posted on by

I do not normally post anything that is purely environmental. I don’t have to. The energy business destroys the Earth everyday. But Honey Bee Colony Collapse is dangerous. Our food supply is under enough pressure as it is.

http://saveourenvironment.org/

Ask the EPA to ban the pesticide that’s killing our honey bees NOW.

Doug,Honey bee populations are plummeting – this is your last chance to help.

Alarming – there’s no other way to describe what’s happening to honey bees. Up to 1/3 of our food supply is pollinated by honey bees. Without them, the health of our food supply is in serious danger. The widespread use of clothiandin is likely to blame, as this pesticide, which is highly toxic to bees, has yet to be conclusively proven safe for our crops. But still, clothiandin has been used on corn – our country’s largest crop source – since 2003!

The EPA is refusing to review the safety of this dangerous pesticide until 2018. Our honey bees and our food supply cannot wait another day. Please, take action TODAY to urge the EPA to save our honey bees before it’s too late.

–Mike
Action Alert
Doug,
Honey Bees In Peril!Pesticides like clothianidin may be killing our honey bees by the billion.

Take action today!

The EPA wants to wait until 2018 to finish reviewing its safety but our honey bees can’t wait 6 more years. And every bee colony that collapses threatens the future of our food supply…

Contact the EPA to help save our honey bees today.

Since 2006, our honey bees have been dying off in droves. Billions of bees have disappeared in the U.S. with losses estimated at 30% per year.1

And if the destruction of a species is disturbing enough on its own, the collapse of honey bee populations also threatens the security of our food supply since honey bee pollination is crucial to the cultivation of a full 1/3 of our food here in the U.S.

Urge the EPA to stop dragging its feet and take steps NOW to stem the collapse of honey bee colonies across the country.

Scientists have been scrambling to figure out what is behind this crisis – termed Colony Collapse Disorder – and believe it is probably the result of many interacting factors, including one widely used class of pesticides called neonicotinoids.

One such chemical, called clothianidin, is produced by the German corporation Bayer CropScience. It is used as a treatment on crop seeds, including corn and canola which happen to be among honey bees’ favorite foods.

Unfortunately, the EPA is refusing to make any changes until it completes its review of the safety of clothianidin in 2018 – but our honey bees (and bee keepers, rural communities and farmers) can’t wait that long.

Tell the EPA: Ban the use of this pesticide that may be wiping out our honey bees before it’s too late.

Shockingly, no major independent study has verified the safety of this pesticide. While clothianidin has been used on corn – the largest crop in the U.S. – since 2003, it was officially approved by the Environmental Protection Agency in 2010 on the basis of a single study, conducted by Bayer.

But leaked EPA documents2 expose a more sordid story. Agency scientists who reviewed Bayer’s study determined that the evidence was unsound and should not have been allowed as the basis for an unconditional approval of the pesticide.

Additional independent studies have shown that neonicotinoid pesticides like clothianidin are highly toxic to honey bees, providing compelling evidence that they should not continue to be approved by the EPA.

France, Italy, Slovenia, and Germany have already banned clothianidin over concerns of its role in Colony Collapse Disorder.

The stakes are far too high to continue the use of this chemical without independent science verifying that it is safe to use.

Ask the EPA to ban the use of clothianidin NOW, not in 2018.

Thanks for helping to protect our bees.

America 9th In The World – I am not sure whether I believe this or not

Posted on by

ACE3 rarely ever gets very much wrong.  But the idea that the UK was the most efficient country in the world and the USA was 9th? There is something very wrong about that.

http://www.energycircle.com/blog/2012/08/15/us-takes-9th-place-energy-efficiency-out-of-12

U.S. Takes 9th Place in Energy Efficiency! (Out of 12).

By Will – August 15th, 2012

A new report from the American Council for an Energy Efficient Economy (ACEEE) ranked the energy efficiency of the world’s 12 largest economies. The U.S., unfortunately, ranked 9 out of 12.

So while we were out dominating at the Olympics, we were quietly slipping behind on a metric that, if improved, would yield a substantial benefit  for our country — economically as well as environmentally.

So how did we do on the specifics?

  • 9th overall in energy efficiency
  • 9th in terms of “national effort” in energy efficiency
  • 6th in industrial energy efficiency
  • 4th in building energy efficiency
  • 12th in transportation efficiency

With our penchant for gas guzzlers and the unpopularity of public transportation over here, it’s easy to see how we came in dead last in transportation.

But a shimmer of hope there is the 4th place ranking we got in building energy efficiency — our best category, and not all that shabby really. (We would have almost gotten a medal if building energy efficiency were an Olympic event.) While we’ve previously lamented our slow progress in implementing energy efficiency in buildings, and have shaken our heads as federal tax credits have been cut and legislation aimed at improving energy efficiency has stalled, it looks like we’re actually doing okay in the field of building efficiency compared to the rest of the world’s developed countries.

Abengoa Solar inaugurates second-generation high-temperature solar power tower

Abengoa Solar’s (Seville, Spain) first high-temperature power tower, dubbed “Eureka,” was unveiled on June 19th, 2009 by Martín Soler Márquez, Director of Innovation, Science and Enterprise for the Andalusian Regional Government, the company reports in a press release. According to the press release, this power tower is intended to test a new type of receiver on an experimental basis and it is expected that the receiver can achieve the higher temperatures needed for higher-efficiency thermodynamic power cycles. The aim of this new technology is to increase plant performance, thereby reducing generating costs as well as the area of the solar field, Abengoa reports.

The new experimental plant occupies a 16,000-squarefoot portion of the Solúcar Platform and uses 35 heliostats and a 164-foot tower which houses the experimental superheating receiver. The capacity of the experimental plant which features a thermal energy storage system is estimated to be about 2 megawatts (MW).

Solúcar Platform solar thermal and PV installation complex to offset 185,000 tons of CO2 emissions per year.

First U.S. Tidal Power Project Readies for Launch in Maine

Posted July 24, 2012 in Solving Global Warming

The ocean is a tremendous bank of energy. Covering more than two-thirds of our planet, the amount of energy embodied in the ocean’s tides, currents, and waves, not to mention temperature and salinity gradients, could power the world—if we were able to commercialize the technology to harness its renewable power.

While technologies harnessing energy from tides and currents have been domestically discussed for decades, no project has ever reached commercial development, and been connected to the grid in the United States. In Eastport, Maine, however, that changed today that will change around mid-August with the launch of the Ocean Renewable Power Company (ORPC) TidGen Cobscook Bay tidal energy project. Harnessing the power of the massive tidal shifts in Cobscook Bay, an inlet connected to the much larger Bay of Fundy, the project is the first in the U.S. to receive a FERC license, negotiate a power purchase agreement, and install and operate a power-producing tidal generator.

As clean energy advocates, we are excited to highlight new, innovative projects that inject clean power and jobs into communities, deploy American ingenuity and know-how and utilize smart clean energy policies. The DOE invested $10 million in the project as part of its larger water power program that aims to better understand the environmental impacts that come with harnessing ocean energy, as well as refine, and make more cost-effective, the technologies that do so.

In addition to harnessing local sources of energy, the project apparently:

This Is The Start Of A Solar Power Meditation – Harvesting the power of the sun

Posted on by

This is just such a beautiful installation. It takes up too much bandwidth to show pictures but here is a written description.

http://www.torresolenergy.com/TORRESOL/gemasolar-plant/en

Gemasolar is the first commercial-scale plant in the world to apply central tower receiver and molten salt heat storage technology. The relevance of this plant lies in its technological uniqueness, since it opens up the way for new thermosolar electrical generation technology.

Characteristics of Gemasolar:

  • Rated electrical power: 19.9 MW
  • Net electrical production expected: 110 GWh/year
  • Solar field: 2,650 heliostats on 185 hectares
  • Heat storage system: the molten salt storage tank permits independent electrical generation for up to 15 hours without any solar feed.

The prolongation of the plant’s operating time in the absence of solar radiation and the improvement in efficiency of the use of the heat from the sun makes Gemasolar’s output much higher than that which is delivered by other technologies in a facility with the same power.

The notable increase in the plant’s power efficiency guarantees electrical production for 6,500 hours a year, 1.5 to 3 times more than other renewable energies. The plant will thus supply clean, safe power to 25,000 homes and reduce atmospheric CO2 emissions by more than 30,000 tons a year.

The power generated by Gemasolar will be sent through a high-tension line to the substation of Villanueva del Rey (Andalusia, Spain), where it will be injected into the grid.

More on Grand Staircase Escalante National Monument

Author: Jeanna Thomas  |  Category: Behind the Scenes, Caroline Raville, Environment, Landscapes, Season Two, TAL on PBS

This is the third in a series of blogs written by This American Land host Caroline Raville on her recent experience shooting  a story for season two at Grand Staircase Escalante National Monument. Read the first two blogs in this series, Grand Staircase Escalante National Monument in Season Two and Host Caroline Raville on Grand Staircase Escalante National Monument.

And now we are crossing over the mighty Paria River,” Dr. Titus observes.

I look down below. I see dirt and a puddle. Dr. Titus and Scott Richardson are grinning at my incredulous look as we bump along the pockmarked road. Apparently, this crack in the mud does become a river occasionally. Escalante experiences extreme weather ranging from boiling, fly-infested summers to frozen winters. Still, the evidence before me seems to suggest that this place is in a constant state of dry heat.

We drive deeper into the monument, and the paleontologists decide to take a quick detour promising spectacular views. After a steep climb with some seriously wicked turns, we find ourselves looking down on a valley littered in rock formations. There are the tar colored hills which look like a blackened sand dune. Further up, rust tinted rocks roll in the shape of a dragon’s back. And above are the whitewashed peaks dotted with green scrub brush. These layers are a physical timeline that helps scientists to establish the changes in habitat that occurred here. From ocean floor to swampland to the now arid desert, Escalante has experienced some major changes during its existence due to plate tectonics and the resulting mountain building.

Oil Stocks By Mike Nadel – Good advice from a good guy

I do not normally boost someone else’s net contributions just because I think the author is cool. Had he not written about oil stocks I probably wouldn’t either, but it is the summer. Because I was getting alittle burnt out on all the serious blogging I have done for 5 years, I gave myself permission to post whatever I wanted too and boringly I have stuck to energy conservation, the residential market and all things environmental. So today is a really “what the hell” kinda day. Enjoy.

Time To Slide Into Oil Stocks

??By Mike Nadel

The last time I filled my car’s tank, I paid less than $3 a gallon. As my wife will attest, I was more than a little giddy. “Two-ninety-seven!?!? You gotta be kidding me!!! This is incredible!!!” Hey, we all have to find life’s little thrills wherever we can, right?

The price of crude oil, the source of gasoline, is determined by numerous factors: supply and demand, the Middle East unrest, natural and unnatural disasters, Wall Street speculators, economies in the U.S., Europe and emerging markets, etc.

Crude oil reached $110 per barrel on February 24 and was still over $100 per barrel two months later. It has been on a fairly steady decline since, hitting $80 per barrel on June 22 – its lowest level in two years – before rebounding into the mid-80s. So what’s next?

I certainly am no oil-price-trend expert… and even if I were, I wouldn’t listen to myself. Wasn’t it just a few months ago that alleged experts were predicting $5 gas by Memorial Day and maybe even $6 by the Fourth of July? Still, when it comes to forecasting oil prices, “Up” usually is a reasonable guess – especially after it has been down.
