Over 400
The latest batch of exoplanets was discovered by an international team of astronomers using the High Accuracy Radial Velocity Planet Searcher (HARPS), the spectrograph for ESO's 3.6-metre telescope in La Silla, Chile. With more than 75 exoplanet discoveries to its credit, the instrument has become a powerful tool for planet hunters.
Perhaps even more exciting to scientists than the big numbers are the increasingly small planets being found. Several of the worlds recently discovered with HARPS are just a few times larger than Earth, marking progress toward the ultimate goal of detecting small, terrestrial planets. However, none of the planets announced last week are considered habitable.
Finding small, rocky planets that might resemble Earth is a key goal for NASA's Kepler spacecraft, which is currently scanning thousands of distant stars for signs of transiting exoplanets.

Mars trip simulation
The crew will follow a programme designed to simulate a 250-day journey to Mars, a 30-day surface exploration phase and 240 days travelling back to Earth. For the ‘surface exploration’, half of the crew will move to the facility’s martian simulation module and the hatch to the rest of the facility will be closed.
Candidates should be aged 20-50, motivated, in good health and no taller than 185 cm. They should speak one of the working languages: English and Russian. Candidates must have a background and work experience in medicine, biology, life support systems engineering, computer engineering, electronic engineering or mechanical engineering.

Saturn, the mini solar system
http://saturn.jpl.nasa.gov/news/newsreleases/newsrelease20091006/
PASADENA, Calif. -- NASA's Spitzer Space Telescope has discovered an enormous ring around Saturn -- by far the largest of the giant planet's many rings.
The new belt lies at the far reaches of the Saturnian system, with an orbit tilted 27 degrees from the main ring plane. The bulk of its material starts about six million kilometers (3.7 million miles) away from the planet and extends outward roughly another 12 million kilometers (7.4 million miles). One of Saturn's farthest moons, Phoebe, circles within the newfound ring, and is likely the source of its material.
Saturn's newest halo is thick, too -- its vertical height is about 20 times the diameter of the planet. It would take about one billion Earths stacked together to fill the ring.

GM still working on fuel cells
With all the trouble GM has had in the last year its good to know that they are looking to the future still. Their second generation fuel cell technology was unvailed yesterday to lawmakers in Washington. Why there? They are trying to get more funds to further their research.
And this isn't a bad thing in my opinion. If the US government really wants to get off fossil fuels and away from foreign sources of energy then this is the way to do it. GM claims this technology will be ready for the market by 2015. While the article doesn't say exactly how many miles the new vehicles get on a tank of fuel the common standard is 300 and that is basically what the last one got. So by making the new equipment cheaper and smaller it cuts the weight of the vehicle and the cost while giving the same performance.
Hydrogen as a fuel is still anywhere from $4 to $8 a gallon when compared with gas so it isn't cheap. But a recent news article says that in order to cut carbon emissions in the US that the government and other countries should stop subsidizing fossil fuels. If they did that gas prices would easily go back to the 2008 levels or above here in the US making hydrogen a good option. Now we just need a fueling infrastructure to support it.

More mileage testing
So how about this for a solution. A hybrid transmission. No not that type of hybrid with mechanical and electric motors, no I mean a conventional one mated with a CVT. CVTs are a great idea, I had the idea years before they actually came on market (although they were certainly already being developed). I usually have great ideas for something only to see it on the market a year later. Anyway, this transmission would have 3 or 4 accelerating gears so that high torque motors could use it too (currently a high torque motor will tear apart a CVT). The final "gear" would be a CVG (continuously variable gear) allowing for a range of cruising speeds at a certain RPM. I think this would be more beneficial than a 10 speed transmission.
*NOTE: I don't have a patent on this and don't plan getting one, there might already be one, but I haven't checked. I don't believe patents should be approved without a working prototype being created. An idea patent would be ok, but in a very limited time frame, say a year for them to build the prototype. I really dislike people that sit on patents waiting for someone else to build something and then suing the person that actually worked to bring the product to life.
What was it?
The coordinates that we were at when we saw it are as follows: Latitude 38°54'22.22"N Longitude 95°22'26.18"W
My main reason for posting this is for any one else that saw it and is searching for information on it.

Pic from Hubble
These images are some of the first from the newly refurbished Hubble Telescope. Truely unbelievable images of space.
Hubble Briefing
They showed the pictures already and are explaining them now. Once the pictures are posted I will get them up here.

New Hubble Images next week
Space shuttle Atlantis' STS-125 mission upgraded the telescope in May with state-of-the-art science instruments, leaving it more powerful than ever and extending its life into the next decade.
Charlie Bolden, NASA administrator and pilot of space shuttle Discovery on the STS-31 mission that launched Hubble in 1990, will join U.S. Sen. Barbara A. Mikulski, D-Md., in the unveiling of the Hubble images during the 11 a.m. briefing. A panel of scientists then will discuss Hubble's new and refurbished instruments and the images they produced.
The participants are:
-- Ed Weiler, associate administrator, Science Mission Directorate at NASA Headquarters
-- Bob O'Connell, chair of the science oversight committee for the Wide Field Camera 3 at the University of Virginia
-- James Green, the Cosmic Origins Spectrograph principal investigator at the University of Colorado
-- David Leckrone, senior project scientist for Hubble at NASA's Goddard Space Flight Center in Greenbelt, Md.
-- Heidi Hammel, senior research scientist at the Space Science Institute in Boulder, Colo.
The briefings will be held in the James E. Webb Memorial Auditorium, 300 E St. S.W., Washington. Reporters also may ask questions from participating NASA locations by phone. To reserve a phone line, journalists should send an e-mail to J.D. Harrington at j.d.harrington@nasa.gov with their name, media affiliation and telephone number.
The second briefing immediately follows at noon. The STS-125 astronauts will discuss how they enabled Hubble's new capabilities during their historic servicing mission.
Scott Altman commanded Atlantis' crew, which included Pilot Gregory C. Johnson and Mission Specialists Andrew Feustel, Michael Good, John Grunsfeld, Megan McArthur and Mike Massimino.

Wireless Power
A company called WiTricity has developed a way to transfer energy using magnetic fields and sending it from source to destination at a certain frequency wave. Their goal was to get more power to travel longer distances. With energy waves, the shorter the frequency the shorter the distance and speed it travels, hence the reason you see the lightning before the thunder, light waves move faster and you might see it but not hear anything if it is really far off.
WiTricity's goal is to have devices without power cables, a device would plug into the outlet and transmit the energy to the TV, Laptop, cell phones (mainly for charging) that has a receiver for the wireless energy which then converts the magnetic waves back to energy it can use. They claim that it will not add much to the cost of devices. One of the biggest advantages I could see is on laptops, both my wife and I have one and while mine can run for 11 hours in low energy mode, hers lasts less than an hour so if we take it outside or somewhere else in the house we have to unhook the power cord and plug it in where ever we are going to be. This would definitely be helpful.
WiTricity claims it is safe and that the magnetic waves are very similar to the earth's magnetic field. Of course the earth's magnetic field mainly emanates from the poles and at lower latitudes it really doesn't affect us. Magnetic fields is one of the possibilities that male fertility is dropping since all powered devices give off electro-magnetic fields. So hopefully they test this before releasing it on the public.

Battery Tech
Li-ion batteries already pack a lot of power into a small package when compared to regular alkaline batteries. They are smaller and lighter than the Ni-Ca and Ni-MH batteries (think old laptop and cell phone batteries). But they are a fairly young battery and practically still in their first generation. That is one reason they are so expensive and the reason the Chevy Volt will cost so much. The next generation Volt will cost less because cost of components will come down including the battery.
Now according to this article they will also be able to probably double the mileage that they can get out of a car with the same size battery. Or reduce the size of the battery pack in the vehicle and get the same mileage. Actually, because the weight would be reduced they would still get better mileage if they halved the size of the battery.
The main question is how long before we see this technology on the road. Since it is a GM owned company and the US government owns most of GM right now there are really 2 ways of thinking. Knowing how government organizations are run, it takes forever to get anything approved. MAGLEV anyone? On the other hand, GM does have some say in what it can do and has said the Volt will be a continually developed vehicle, if the batteries are ready we could see the new battery packs in the first generation Volt in its mid life face lift probably around 2014 or 2015.

Stellarium
Stellarium is what you want. Go to http://www.stellarium.org/ to download it. It is free and a great program. The other day when we were camping I was pretty sure the bright object in the sky to the south west was Jupiter, but wasn't for sure. Last night I checked it out on Stellarium and sure enough it is. I also couldn't find the little dipper or Polaris (the North star). I know 2 of the stars in the big dipper pointed to it, but wasn't sure which ones. With Stellarium I found that it was the 2 stars on the end of the dipper that point north to Polaris which is part of the little dipper. But because of the light of the city, it is hard to see.
It might run slow on a low end system, so it might not be for everyone. But just so you know, it does run on Windows 7.
Kepler ready to go
The graph above shows when the planet passes in front of the star and how we would see it in phases as it did so if we could actually see it. But kepler is only going to detect and find the planets, another telescope to launched in a couple of years will hopefully get the first real pictures of an exo-planet. Keplers mission is to find earth sized planets in the parent star's habitable zone.
The current count on the number of exo-planets is 357. Most being huge gas gaints even larger than Jupiter.

New engine design
Ilmor Engineering has developed an innovative 130bhp, 700cc, three-cylinder, five-stroke petrol engine that develops the fuel economy of a diesel engine without any of the emissions shortcomings.
The engineering firm, which has a long history working in motorsport and which was previously part-owned by Mercedes when it prepared its F1 engines, has developed the radical road car engine to showcase its engineering ability.
This is one engine that has promise. The company says that this is just the beginning and that they will improve on the concept cutting the weight of the engine and increasing HP possibly to 150. For a 3 cylinder that is great.
I still find it interesting that all these new technologies for the internal combustion engine are popping up all over the place, yet for the last 100 years the engine had pretty much remained the same. It was only recently (little over 10 years ago) that Porsche managed to get 100bhp per cylinder, now a lot of people have that.

Mileage results
With this small tank of gas I am going to start using the neutral coasting down the hills. This drops the RPMs to about 700 rather than 1500 with it in drive. I've tried the shutting off of the car at stop lights before and that is taking it a little to far. I also don't agree with the people that run the stop signs to keep from having to stop. I'm thinking the coasting should get me at least another .5 to 1 mile per gallon.

New tire tech
Manufacturing tires from a renewable plant source could be less expensive to produce than tires using carbon black which is made from oil, or silica which takes a lot of energy to produce.
But aside from the manufacturing benefits, the researchers found that the cellulosic rubber tires had better traction on wet surfaces and less effected by heat compared to conventional tires.
"Early tests indicate that such products would have comparable traction on cold or wet pavement, be just as strong, and provide even higher fuel efficiency than traditional tires in hot weather," according to a report from Kaichang Li, associate professor of wood science and engineering in the OSU College of Forestry, and Wen Bai, a doctoral student who collaborated on the project.
This is promising. But I have heard other tire technologies that they have been working on for a long time and nothing came of them. Really until there is a reason to change, they won't change.

New Duramax diesel for GM
Although the program is “on the shelf,” General Motors Co. Vice Chairman Tom Stephens says the auto maker’s Duramax 4.5L V-8 turbodiesel is ready when needed.
“The program is essentially complete and could be implemented whenever we choose to do that,” GM’s vice chairman-product development tells Ward’s in a phone interview.
The Duramax diesel was expected in GM’s ’10 light-duty fullsize pickup trucks, the Chevrolet Silverado and GMC Sierra, and possibly future cross/utility and SUVs.
But the auto maker’s misfortunes, culminating in a June 1 bankruptcy filing, caused it to cancel the mill’s spring introduction. Another hurdle is declining gas prices, making fuel-saving diesels less alluring for many consumers.
Developed over nearly four years and due to be built at GM’s Tonawanda, NY, plant, the engine’s design defies conventional diesel technology with reverse flow of air and exhaust gases entering and exiting the cylinder heads.
Exhaust gases exit toward the center of the engine directly into the turbocharger, which is located in the “V” between the heads. Placing the forced induction system between the cylinder banks is a cutting-edge design that saves weight and space and improves performance and emissions.
Very interesting that it runs reverse what any normal engine does. Maybe they should try some gasoline turbo charged V-6s like that along with the laser ignition and all the other new tech coming along.
Lasers instead of sparks
Scientists at Liverpool University and engineers at car giants Ford have developed a new ignition system which uses focused beams of laser light to ignite the fuel.
The researchers claim the technology is more reliable and efficient than current spark plug technology and will enable cars to start more easily in cold and damp conditions.
In the new system the spark plug is replaced by a laser powered by the car battery which is sent along thin optical fibres into the engine's cylinders where lenses focus the beam into an intense pinprick of light.
When fuel is injected into the engine, the laser is fired, producing enough heat to ignite the fuel and power the engine.
The researchers claim that the laser, which will need to fire more than 50 times per second to produce 3000 RPM, will require less power than traditional spark plugs.
Some of the laser can be reflected back from inside the cylinder to provide information for the car on the type of fuel being used and the level of ignition, allowing the car to adjust the quantities of air and fuel automatically to optimise the performance.
There is no telling when we could see this in production but it does have promise. With the advantages of using a laser and be able to do multiple beams and precise targeting for a combustion camber it could definitely improve power and economy in the standard gas engine.

Super Lotus
http://www.autoexpress.co.uk/news/autoexpressnews/236575/lotuss_reborn_esprit_gets_v10_power.html
Report from AutoExpress.co.uk
A legendary Lotus is returning – it’s the new Esprit! The dust has only just settled on the stunning Evora, but already the Norfolk firm is setting its sights even higher. And our exclusive pictures show how the reborn supercar will take shape.
The entry-level Esprit will be equipped with a tuned version of the Evora’s 3.5-litre V6, producing around 300bhp, while a mid-range model gets the 414bhp 5.0-litre V8 from the Lexus IS F. But taking the new Lotus into the big league will be the earth-shattering 550bhp 4.8-litre V10 from the upcoming LF-A supercar.
Mated to a six-speed semi-automatic paddleshift transmission, this unit should provide the Esprit with performance to match some of the fastest cars on the planet.
A 0-60mph sprint time of less than four seconds is expected, and judging by pre-production testing of the LF-A (see Issue 1,066), the car is likely to hit a top speed in excess of 200mph.
Nice looking car and a promise to be fast. Probably expensive too. While I'm sure I would never be able to have one I can't wait to see one in person someday.
Nissan Introduces Dual Injectors
Nissan announced today that they have developed a dual-injector system to increase fuel-efficiency on its small-displacement gasoline engines.
“The new fuel delivery system, the first of its kind in the world, uses an injector for each port rather than one per cylinder - speeding up fuel vaporization, reducing the amount of unburned fuel and reducing hydrocarbon emissions, Nissan said in a statement.
Amazing the advances automotive engineers have been able to come up with in the last couple of years since they have been really pushed finally to stop building the same old junk they had for so long. You have to wonder what the internal combustion engine has coming for us next.
Open source car?
Former British racecar driver Hugo Spowers unveils the 2-seat fuel cell-powered Riversimple Urban Car in London, which will see 10 prototypes built by the end of 2010 and 50 more by the end of 2011.
Beginning in 2013, the vehicle will be available for a jaw-dropping 20-year lease at a cost of £200 ($315) per month, which includes fuel, Spowers says.
The major investor in the Riversimple car is Sebastian Piech, great-grandson of Porsche AG founder Ferdinand Porsche and nephew of Volkswagen AG supervisory board chairman Ferdinand Piech.Nine years in development, the Riversimple car weighs a mere 772 lbs. (350 kg), and developers claim it achieves a fuel economy of 300 mpg (0.78 L/100 km), emitting just 30 g/km of carbon dioxide.
“We believe we are closer to market with a commercially viable fuel-cell car than anyone else,” Spowers says.
The FCV's simple design, which eschews gearbox, drive shaft and heavy power-assist braking and steering, enables it to run on the minuscule 6 kW fuel-cell stack. In comparison, larger FCVs from major auto makers typically have at least 100 kW fuel cells.
Spowers forecasts production of 5,000-10,000 units of the FCV annually. He also promises the company will provide free, “open-source plans” on the Internet for downloading in order for entrepreneurs to develop their own variations of the vehicle.
Other manufacturers also will be able to source parts locally, with the only stipulation being any improvements must be shared, so the entire network of builders can benefit.
Unfortunately the top speed is only 50 mph, but since it is open source I'm sure others will quickly get that up to highway speeds. This may be the vehicle to change the future of motoring, we'll just have to wait and see.

Lightning Car Company
The creators of the Lightning GT electric-sports cars are planning three additional models, reports AuotCar. The Lightning GT is scheduled to go into production early next year with a starting price-tag of around £120,000 ($196,014 USD).
The 700 horsepower Lightning GT EV is capable of traveling 250 miles with only 10 minutes of charging. 0 to 60 mph comes in just 4 seconds with a top speed of 130 mph.
That's quite an advanced system it has if it can charge for 10 minutes and then drive 250 miles. And a 700hp electric motor, that is impressive. Can't wait for more specs on it and when it will actually be available. Unfortunately it sounds like they are a high end automaker only and normal people will not be able to get one of these.
NHTSA considering amber turn signal mandate
http://www.leftlanenews.com/nhtsa-considering-amber-turn-signal-mandate.html
I bet if people actually used their turn signals it would be even more effective in preventing the wrecks. Every little bit helps though.
New prototype engine
Key to the powerplant is the split-cycle design, which separates the intake and combustion processes into separate cylinders. Air compressed in the first cylinder (at a 100:1 ratio) is transferred via a crossover passage to the combustion cylinder, where fuel is indirectly injected by twin injectors.
It takes just one crankshaft revolution to complete a single combustion cycle, rather than the two revolutions required by conventional engines. Scuderi says it is possible to get 140 hp from a 1L displacement, using its design.
This sounds like a very promising new engine although it doesn't say what kind of mileage it gets. It could be like a rotory engine that is 1.3L but gets the mileage of a 3.6L. Hopefully that is not the case since it does cut the emission levels. And 140HP from a 1L engine, WOW! Now if they could just get it to run off hydrogen.Saturday, June 6, 2009
Autos
But it isn't just the Chevy Volt anymore that will be using this technology. independent automakers are springing up to fill the high mileage car void since most of the large automakers are still to afraid of big oil to really come out with anything ground breaking. Not to mention hybrids are still niche vehicles and they can charge more for them. Yes, I know, the new Insight is cheap, both in price and quality, have you read Jeremy Clarkson's review on it?
As for hydrogen, gasoline prices have to get back to over $4 a gallon for hydrogen to be even close to competitive. And the oil companies realized after last years gas price hikes that they did the world economy wasn't ready for it. They are the ones that crashed the whole system. If it wasn't for them, the fragile housing market and the bad banking practices would have gone on like normal.
