A polywell is a device that is used to electrical field work on ions, heating them to fusion conditions. It is a fusion reactor that uses a magnetic confinement to trap electrons.

Artificial fusion has been achieved already. In fact it has been done in different ways.

The problems with fusion include how to achieve it without consuming more power than is produced, and how to keep such a reaction going. The Farnsworth-Hirsch fusor is a fusion reactor a student might build as a project, but it sufferes these problems.

Another problem with fusion is that many of the methods tried are expensive to test. The polywell is a reactor with such a problem. It is the result of many years of experimentation by Robert Bussard. According to Dr. Bussard, the polywell worked briefly before the apparatus burned out. Unfortunately he lost funding, and then died, and the effort is slowed as a result, so we do not actually know he was right.

So the answer might be that we already have achieved practical fusion. We just have to determine that it is true. Or the answer might be that we have not achieved practical fusion, and if that is the case, it might be years or decades away.

There are many things that fall into this category. If you are looking for an example, the Energy Amplifier, also called an Accelerator Driven System, is a good on. The inventor won a Nobel Prize, the design has been successfully tested, and a lot of information on the system is available, but the actual plant has not been built.

In the same industry, you might look at the polywell, which reputedly is capable of cold fusion and has been successfully built and tested, but the test has not yet been confirmed.

There are a lot of pharmaceuticals that are in the testing process, and these can be found by doing a little research. They often appear in the news.

You might look at http://www.polymodular.com for a type of building module that has never been put into production.

I was just looking at QVC.com and they sell ZT System laptops that are made in the USA!

There are several companies building laptops in the USA. Zt Stysems, Systemax, Lotus PC, Polywell. They are generally supported by Americans too, a nice perk.
