Now, as the voltage vs charge cap/density, yes, you are correct that CURRENT tech does sacrifice. However, if storage at the station, then not a big deal. And as to the rest, it is amazing what they can do with power these days. Just amazing.
And as loses? Well, lets see. You take a charge from a train and then give it right back to it several minutes later. Somehow, I do not think that the minor amount of loss in that length of time is a big deal.
BTW, this also has another advantage. It becomes possible to store energy from the lines for use in various applications. It can even be used to buffer the lines. Caps are pretty handy about that.
I still say go with ultra-caps and use this to help spin up an industry. Once geared up, then they can sell more elsewhere.
By using ultra-caps at the station, they get to drop the price of these. In doing so, they make it available for other technology. The advantage of ultra-caps is that it has power. In addition, while some of the ultra-caps do not retain energy for days without loss, this is simply shot back into the system in under 5 minutes. The loss is nominal. Finally, most rail systems have more cars, trains, then stations. It is actually cheaper to put these at the stations, using the electric system, then to retrofit all of the cars. Also, not making the cars carry the charge system around is more efficient.
The reason is that ATT will be forced to build out a network. By buying them out, it really does not help the industry or consumers. OTH, T-Mobile has built out all over the world. And iphone is simply not needed. Android is bigger and will continue to grow.At some point, iphone will choose to sell to t-mobile. Otherwise, it will encourage android to eat into their space.
to any and all tech degrees, University should have 1-2 classes that will give you a decent intro to business. Ideally, if you can pick up a minor of some type in entrepreneurial business. The reason is that engineers working for larger company are going to get screwed over no matter what. Engineers that come up with PATENTABLE ideas and then start their OWN business, will clean up quickly.
However, for a dual major, ME and CS are excellent choices.
It is long past time that we put on the ability to control access. If you look carefully at China's internet controls, they can be used EITHER way. It can be used to control their outbound, but it can also be used as a wall. With this approach, China is building a wall, but will have first strike capability on Western Computers. Now, if it only took out simply company and personal computers, no big deal. HOWEVER, it is not. Even our seperate networks are done virtually. Some ppl say that vlans are secure, but nothing could be further from the truth. Verizon, ATT, and Qwest have outsourced a great deal. Verizon in particular, makes HEAVY use of Chinese admins. Insane that we would do that.
We shipped food and all sorts of goods to USSR and China with them. In fact, it was by getting their money that we bankrupted USSR. But when a nation spies on another to the degree that China does, and is attacking via the internet, yeah, that is Chinese Gov's cold war with the west, esp. America. To say otherwise, is just simply lying to yourself.
immigrants, esp. illegals, bring it in. But with so many kids not vaccinated, it has spread quick enough. Just like small pox, we really should make it a mission to vaccinate EVERYBODY on this planet.
And yet, I do not gather that is what he is saying. He is saying that he wants something different. He wants to make a difference. If smart(and he is), he will try to apply this back to Google and work with them.
If you do not care about the human life, then perhaps you will care about your tax and insurance dollars. I would love to see insurances say to parents that if you do not immunize and your kid is sick, then the deductible is raised to 10K for any and all complications from these kinds of issues. The fact is, that it costs lives and money.
What makes you think that it would be inferior? When I worked there, we had production of printers, PCs and HP stations just downstairs. We could go see and talk to the production ppl. You would be surprised what can be found out by talking to the line ppl.
In addition, chips, board and even system manufacturing is now energy intensive and low labor. The reason is that it is extremely automated. Energy is cheaper in America than in China.
At the equator, you will have 30 days of sun followed by 30 days of darkness. There are some spots on the lunar poles that are thought will provide about 98-99% light. Still, you can not move far from it.
Yes. And they all agreed to formats. But, when you can not get agreement on something as simple as plug/voltage, then I would give little to no chance of batteries. Keep in mind that every car has a different type battery and different form of storage. Some put it between the seats. Others in front, while others do it in the back.
I think that we should do some more R&D into using beta- emitters. In particular, if there is a lot of nuclear waste that can provide this power. And heat can be use for local heating. The big issue is that neutrons are emitted and have to be dealt with. However, if this is done, then we are looking at a nice way to provide power for even VASIMR, and perhaps for ships, larger earth movers, etc.
Slashdot Mirror
it is date of invention idea. If he, like many others, did this in the 80's, then it should be expired.
However, what amazes me is that with a patent like this, I am waiting for a patent to be approved for breathing.
Well, Lets see.
LRT system vehicles are powered by 900 volts direct current (Vdc) electricity. The Traction Electrification System provides power via a traction power system and
WOW. So, they are using 900 volts DC. So, that means your first part is WRONG.
However, you are right on high voltage. It is 900 volts. But, how do we go from low voltage to high-voltage? Oh yes. SERIAL CONNECTION.
Now, was that so hard? Nope.

oops. thanx. I meant to say linear motor. just sloppy.
actually, our new ones use maglev systems.

However, on a side note, good find WRT the subject. It really shows how unethical large businesses really are.
But that is helping to justify the paywall. No links and suddenly paywalls do not look so good.
I think that it is time for /. to consider saying no to posts that have links behind paywalls.

duh. wrong story.
China is starting to dream big. That is a good thing. Hopefully, the dreamers will take over their gov. and stop their cold war.

Seriously, if this works decently in salt water, than this is very useful. OTH, if this requires fresh water, then hmmm.

So, the manufacturers can not agree on a plug and voltage, and now, your great idea is to be able to swap batteries?
Are you daft or something?
You have multiple companies that can not even agree on a plug and voltage, however, you think that they will now agree with batteries?
