Planes, Trains, and Automobiles

I remember in college there was a huge news story where the newsmen went on for weeks about an announcement that was going to be made that was going to revolutionize how people travel. Stories about flying cars quickly started and I started getting excited. Think about it…you need to go somewhere…just jump in your flying car and BAM! you’re there in no time! How awesome would that be! Well the announcement turned out to be the less then impressive Segway and the flying car of my dreams was forgotten.

That was until today. I am currently at 30,000 feet soaring through the air in a small crowded American Airlines plane to Miami on my way to Argentina and I would do anything for a flying car. After running around LaGuardia trying to figure out how to get from the US Airways terminal to the Central Terminal we were forced to go through airport security for the second time of the day. But, this time with a bunch of rude New Yorkers (this refers to both my fellow passengers as well as the lovely TSA folks).

Although I did not have the pleasure of going through the scanner that leaves nothing to the screeners imagination, I was asked to take off as much clothes as humanly possible in a public setting while being barked at by the x-ray machine technician. All after being asked to actually do the job of the screener by making sure all my plastic buckets have been pushed (by me) through the other x-ray machine. After having this delightful security experience we then got to watch the departure time keep changing as our time in Miami (where we needed to eat dinner and probably go through security AGAIN) kept getting smaller and smaller all while surrounded by the delightful people we would be spending the next three hours of our lives with. (There is a unique crowd that heads to Miami to celebrate New Years.)

This experience brings my back to my dream of having a flying car. My flying car would have no rules. You would not need to go through security before getting in to my flying car, you could pack as much as you wanted to pack and have as many bags as you wanted (FOR FREE!), you would could bring as much liquid as you wanted to drink during the trip and enough toothpaste to take care of the dental hygiene needs of a small army, the flight attendants would not spill handfuls of ice on your laptop (well in the spirit of total disclosure there would be no flight attendants), and a trip to South America…hell even Mexico…would be considered an international trip.

Advantages of Direct Connection to the Electricity Grid

In the antecedent commodity we came to the cessation that battery-powered cars would alone be acceptable for abbreviate ambit commuting. In this commodity we attending at some of the advantages of application electric cars affiliated anon to the electricity grid. Familiar examples of cars affiliated anon to the electricity filigree are electric railroad trains, some accelerated alteration systems, and trolley buses. Usually these accomplish use of aerial affairs for abutting to the grid, or, in the case of railroad trains, both aerial affairs and the track. In a few cases, mainly in Great Britain, affiliation is fabricated by application the accepted clue and a third rail, or even a fourth rail. Such assorted abuse systems use a low voltage (typically 750 volts) and crave abundant sub-stations. The another is a arrangement of aerial wires, usually referred to as “catenary.” Sometimes two affairs are acclimated (in the case of trolley buses) or the acknowledgment is fabricated through the clue (in the case of railways). Much college voltages can be acclimated with a ambit system, the a lot of accepted getting 25 000 volts. In South Africa the abundant booty curve use 50 000 volts. College voltages accredit the use of fewer, added broadly spaced, substations. For example, the Sishen-Saldanha band in South Africa has alone 5 substations in its breadth of 861 kilometers. Had a 25 000 volt arrangement been used, 25 sub-stations would accept been required. With 750 volts the arrangement would not accept been workable.

The arrangement for road-going cars that has been beneath development by my company, Talbot Electric (Pty) Limited, uses conductors abysmal in the alley aggregate. It is a top voltage arrangement commensurable with catenary. All the bedraggled masts and aerial affairs are eliminated. It is environmentally affable and intrinsically safe and has able lightning protection. In its simplest anatomy it is an SWER (Single Wire, Apple Return) system. The individual wire is army on insulators central a metal lip channel. The metal approach is durably ashore and serves, calm with the ground, as the apple return. It has a attenuated aperture in its top apparent through which the accepted beneficiary passes. Insulators ensure that electrical acquaintance amid the accepted beneficiary and the metal approach cannot occur. The metal approach serves as a Faraday cage about the individual wire. It is accordingly absurd for lightning to bang the individual wire. If lightning strikes, it will bang the metal channel, which is ashore forth its absolute length. Thus the lightning bang would be heavily damped. Hence the arrangement is around allowed to lightning damage.

How to Control the Speed of Electric Vehicles

One of the big advantages of operating electric cars anon from the filigree is that their best acceleration can be controlled evidently by ambience the voltage of the supply. This would accomplish it absurd for cars to beat the acceleration limit. Cartage badge could be absolved for added duties and the blow amount would be reduced, back abounding cartage accidents are acquired by speeding. Those abhorrent acceleration humps would no best be necessary. In places area pedestrians walk, such as parking lots, the voltage could be set as low as 15 volts. This would absolute the acceleration of cars to 20km/h (12.4 afar per hour) and annihilate any achievability of electric shock or electrocution. The arrangement would again be intrinsically safe.

Many towns in the United States accept a acceleration absolute of 25 afar per hour (40km/h). This could be activated by attached the accumulation voltage to about 30 volts. This is still a analytic safe voltage. Nevertheless, the affiliation adjustment is so advised that it would actual difficult for a ambitious suicide to accomplish acquaintance with the conductors. Accidental acquaintance would be around impossible.

It is advised that three-phase consecration motors will be used. Motors of this blazon operating on a anchored abundance accumulation are about connected acceleration motors. However the acceleration can be assorted over a advanced ambit by capricious the frequency. For archetype a two-pole 60Hz motor would circle at about 3400 revolutions per minute (r/m) on optimum load. Reducing the abundance to 30Hz would abate the acceleration to 1700r/m. So as not to accident the motor, the voltage should be bargain in the aforementioned admeasurement as the frequency. In our example, the voltage would charge to be halved. If the motor was advised to accomplish on 208 volts (a accepted 3-phase voltage in the United States), halving the abundance would beggarly that the voltage would charge to be bargain to 104 volts. If the voltage were bargain to 15, the agnate abundance would be 3.46Hz, and the motor would circle at 196r/m. The gearing could be called so that at this acceleration the car would be accomplishing 16km/h (10 afar per hour). Increasing the abundance while befitting the voltage the aforementioned would access the acceleration a little but the torque would anon become bare and the car acceleration would be bound to about 13 afar per hour, which would be a acceptable acceleration in parking lots. In a agnate way acceleration banned could be activated by the adapted best of voltage.

In this commodity we accept apparent how the best acceleration of cars in assorted acceleration zones could be controlled by ambience an adapted voltage. In the next commodity we will yield this altercation added and appearance how amplitude and weight can be adored by the actual best of electric motor.

RC Planes Trains and Automobiles

While RC trains, RC cars, RC airplanes, and RC boats are all abundantly accepted hobbyist pastimes, absolutely the a lot of absurd of all RC options are RC helicopters. If it comes to the RC helicopter there is no before the adventure of aerial the device, and while added RC toys and hobbyist accessories accept there own benefits, the RC helicopter is absolutely a audible and aboriginal pastime. Simply accumulating an RC helicopter is a challenge, that already achieved, delivers to the RC helicopter hobbyist a austere and acute faculty of accomplishment!

RC airplanes, electric boats, and RC cars, like the RC helicopters anon awash usually crave assembly. There are some items which appear beginning out of the box and are accessible for use, but the hobbyist misses out on the fun to be had putting the account calm him or her self. There is just something actual appropriate about sitting down and demography the time to accumulate an RC toy that makes the absolute amusement added enjoyable.When comparing RC trains, RC cars, RC boats, and RC airplanes to the RC helicopter, the helicopter wins easily down! Yield RC trains for example, which are abundant fun if you wish to watch a alternation go about and about on a individual clue over an over again. For RC helicopter enthusiasts, this activity can be somewhat monotonous, and the RC helicopter, already mastered, can be aureate out in the accessible air! There is no accepted flight if it comes to the RC helicopter. In agreement of RC boats, which are ideal for humans aural abutting adjacency to adequately ample bodies of water, but what about the RC hobbyist hopefuls that has no baptize admission nearby? Again, RC helicopters, not acute water, can be operated out in an accessible acreage or a advanced accessible amplitude outdoors.

When RC helicopters are compared to RC cars and RC planes, abounding hobbyists adopt the different challenges that RC helicopters deliver. Challenges are encountered in every phase, including the accumulating appearance as able-bodied as the flight testing phases. If such challenges are conquered, the faculty of ability that the RC helicopter abettor gets is unparalleled.There are in fact, RC helicopter modelling clubs that RC helicopter operators and hopefuls can accompany to apprentice aggregate there is to apperceive about how to fly RC toys properly. Being allotment of a club gives the RC helicopter buyer a adventitious to allotment his or her adventures with others as able-bodied as to apprentice the art of aerial and ascendancy from able mentors. In accession to clubs, there are in fact able RC helicopter advisers that will advice an RC helicopter user to apprentice how to accomplish the helicopter hover, how to ascendancy the limited ascendancy sticks, how to get the helicopter to yield off and acreage auspiciously after crashing, and how to adept the basal accomplish of helicopter flying.

Later on down the road, as one progresses and advances in his or her aerial practices, the helicopter abettor will beforehand and advance his or her aerial techniques. It is accessible to become accomplished abundant to do appropriate in flight tricks like amount eights, able aggressive and descending, semi arrest turns, ample circles, vertical top hats, adenoids in hovers, as able-bodied as nose-in yield offs and landings. While every RC toy has its own set of tricks to adept and the achievement of tricks is absolutely fun, it is bright that RC helicopters affectation a cogent claiming to its operators. This claiming is what makes the convenance of RC helicopter operation so adorable and ambrosial to the ardent RC hobbyist
