    Comments: Of course you can. A robot that is built anurod a frame that is lighter than air (like a blimp or zeppelin) can easily be designed to be solar powered. Solar power doesn't provide enough energy for a regular airplane, but since blimps don't need power to float they are ideal for solar-powered vehicles.However, such a robot would be of only limited use on other planets.Some planets, like Mercury, have no atmosphere at all, so such a vehicle could not fly. Other planets like Mars have very thin atmospheres so a blimp-type aircraft would have to be enormous to fly.Some planets have thick atmospheres. Venus, for example, has an atmosphere much thicker than ours. However, Venus' atmosphere is very cloudy so any solar-powered vehicles would have to remain above the cloud tops to remain powered. And the clouds are made of sulfuric acid, and are extremely hot, so your aerobot would have to be very sturdy in order to survive.Other planets like Jupiter and Saturn have atmospheres that are less dangerous than that of Venus. However, at Jupiter the sun only provides 1/25th the energy it provides here on Earth, and like Venus, Jupiter is pretty cloudy. Saturn is even worse, receiving 1/100th of the solar energy that we get here. The planets of Uranus and Neptune are even further away.So in short, on planets where solar energy is easily available, such as Mars and Mercury, an aerobot wouldn't be able to fly. But on planets where an aerobot could fly, like Venus or Jupiter, solar energy isn't really an effective power source.References :

    Comments: , it is time to give kudos to a leader and good gcvnreanoe.PM Thompson and his Cabinet have just actioned two issues that we have raised in the past.The first, raised some time ago, is the appointment of temproary workers.Having these workers in temporary' positions for substantial time, greater than six months, is against any reasonable employment practice.Government has now lead the way in recognising this and kudos must go to the PM and Cabinet for actioning to remove an unfair practice.Secdondly, I see that the PM has asked to meet with the principals of LIME to discuss the closure of the call centre and firing of more employees..With Barbados having been the source of huge profits for Cable & Wireless (now LIME) for many years, including current, we have already said that it is both unnecesary and immoral for thatcompany to lay off staff in such a manner, when the jobs still need to be done, despite small savings by taking the work elsewhere.Further, in this economic climate, this action shows a lack of respect for the Barbados economy and for the social fabric of our society, by sending people home in the midst of an economic crisis worlwide, when the company is itself still earnings huge profits, the company is not even scraping to make a small profit, which would be grounds for restructuring at this time. This action is truly abhorrent and inhuman.Know that most Barbadians are deeply disgusted by LIME's actions in laying off these staff in this manner, in this circumstance.Kudos for the PM and Cabinet in raising this directly with the company's officials.While law may not allow the PM to change the action of the company, hopefully moral suasion can do some good and not only save jobs at a critical time, but also save face for LIME. This is an opportunity for management of that company to save face in the eyes of the public.Peace & live Strong.

    Comments: Reply to Straight Talk You can find out much more about drill ship and semis availability and age, by going to the net.You can find atucal rig counts in any part of the world, just about. It is not only rigs, on and offshore, that are in drastic short supply, but everything that goes with them, like drillpipe, casings, downhole pumps, pipe handeling tools, cementing units, and completion equipment, but probably most of all, experienced men, according to drilling friends in Trinidad. Young people don't want to get stuck out half their lives on rigs any more, to learn what they need. I'm really not into the bidding and all that process, which to me is a dark deathly subject, full of stealth and politics. I just stayed with the rigs. The net can fill you in on most of that, if you just ask the right questions. For instance, go, on Google, to Barbados Offshore Oil Leases, and you'll get all the maps. Anybody in the world, can see the blocks there. Now the steam. We drilled five steam wells in the Sulhur Springs area of St Lucia in 1975-6. Great fun and exciting, and at times horrifying, and very noisey when the wells were being tested, . etc. But all that is an old story, of long ago, and the Trini crews took over all the nice girls in Soufrier.

    Comments: I have realized some new issues from your website about pcs. Another thing I've always presumed is that computers have become an item that each home must have for many people reasons. They provide convenient ways to organize households, pay bills, shop, study, tune in to music as well as watch tv programs. An innovative way to complete these types of tasks is by using a notebook. These pcs are mobile ones, small, highly effective and mobile. jrdan pas cher
