@jmiller – At times we feel ashamed that we are living in a society surrounded by thieves. Imagine someone stealing a manhole cover and selling it. This indicates that this equipment is definitely in danger.
@jmiller – They could develop a billing system to ensure that only people who pay can use this service. I'm sure you can't give it to the public for free. The equipment cost and the power consumption needs to be recovered.
Leto, you said,"2 points on AL instead of Copper. 1st Copper is a better conductor than AL theirfore using AL will increase wasted energy as heat. Opposite of making things more effecient. 2nd Mixing AL and copper is deadly if not done right it is a fire waiting to happen. If done properly it is safe but a # of home fires happen every year from these 2 materials improperly mixed in wiring."
Sorry, you are not wrong. But, the reported data is flawed.
First, aluminum is less expensive and it is also a good conductor, one simply uses a thicker conductor to increase conductivity. In that way aluminum is just as efficient as copper for wiring.
Secondly, careful attention to detail is required but it is improper connections which are the problem, I have made many aluminum/copper connections and mine have Never failed however I have seen overheated connections in pure copper wire systems if they were not properly assembled. Electrical wiring is no hobby, become properly trained or hire someone who is properly trained. I expect a lot of home fires are the result of flawed copper home wiring. And considering the much greater usage of copper over aluminum the copper is likely the cause of more fires than the aluminum.
It accommodates your house but the average load will go up and out off sustainable under current system. Yes they should build more plants but regulators and greenly and local groups keep stopping them.
California could even build a solar plant in the desert for fear of hurting a lizard.
This my hole point we need to get capacity increased before we go he'd long down the EV path
EV is the future but we are not ready yet on so many fronts and blind faith in it will not solve the engineering challenges ahead of us
You other gas kW is just bogus run the numbers and you get each refinery requires a large nuke plant just to provide the power
The problems with the grid that increased wind and solar generation has more to do with the stability of the grid not the capacity of the system. Paul Mauldin has very succinctly captured what the future for California might look like if steps are not taken to mitigate the issue. As wind and solar generation ramps up and down over the course of a day, the base load generation will have relatively severe slew rates to accommodate the customer loads.
Look at the slope of the red line in the graph. This is the load changes that will be required of the conventional generating sources. Here are some more articles alluding to the grid stability issues that result from large scale PV and wind generation.
EXCUSE ME, my switching scheme alternates between charging and the major cooling load automatically so both can be acomodated into the future. The electric cars are not yet here (Only 200,000 os a small fraction of the 300 Million that are coming in the next 10 years.) Obvously the utilities need to upgrade the grid because of growth in consumer consumption already. Don't try to blabe the electric cars the grid is being overloaded NOW what are the utilities waiting for (More free taxpayer grant funding?) It is time to cut back on dividends and upgrade the grid NOW! And it is NOT the electric cars as only 0.06% of the automobiles presently in the USA.
Kindly consider that the gasoline refinery requires energy to refine the gasoline from crude oil, in fact about 7.5 KWhrs of electric power is needed to operate the refinery in producing each gallon of gasoline produced. My electric car can drive over 25 miles for 7.5 KWhrs of electric energy, without using any gasoline but your car may get about as far from that gallon of gasoline. Don't you see we used as little electricity to power the electric car as the refinery used to refine the crude oil into gasoline for you to use driving your gasoline burning car the same distance, and we didn't need to import and burn the crude oil or gasoline refined from it either. I still say it is not the electric cars, it is the failure of the elecrtic utilities who need to cut back on dividends and upgrade the antequated grid at their own expense.
I can believe the number. I'm sure it was a trade-off between durability and efficiency and cost. Pick any two. I doubt rust would have been an issue because I am almost certain the core material would have been some type of ceramic ferrite which doesn't rust. However, if the ferrite was "brought to the surface" of the paddle to reduce the air-gap, it would be more susceptible to physical damage as the ferrites are very brittle.
Electrical connectors are almost universally the weakest point in all electronics. Eliminate connectors and your reliability goes up. A lot.
I'm not a particular fan of wireless charging schemes but I also know well the pains that connectors and connections can cause in electrical systems.
I could design you a paddle charging system with about 90-95% efficiency, but I am certain it wouldn't meet any of the manufacturing cost targets and the users would probably not like the ease of paddle insertion/extraction necessary to reduce losses due to fringing.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
