Just wondering, If we use linear magnetic confinement method alone.

And if the magnetic field is strong enough, will it be able to compress the hydrogen isotopes until they start to fuse to become helium atoms and release energy?

(Was reading some article in http://www.prc.tsukuba.ac.jp/en/?page_id=43 - Japanese's plasma research...

and so i start to think about this question )

Just wondering if natural gas fuel is lot cheaper than petrol(gasoline)

Why the car manufacturers don't produce car than run on natural gas (switchable between petrol/natural gas).

From what i know if the car user wanted to install CNG tank, after he/she bought the car he/she has to install it in a CNG installation workshop, and than go to (government appointed department) to test the car and obtain approval. Isn't this very troublesome?

Maybe this is the reason that many people reluctant to use natural gas as fuel for their vehicle.

Some manufacturer of the R410-A(new gas) aircond claim that their aircond is able to achieve 46% less energy consumption compare to the old type(R22) aircond. Just wondering how true is that?

Say i have a laptop, i reformat it and re-install Windows 7.

After installation, it need to be connected to internet to activate the product and do security updates.

During the process of downloading security updates, is it possible that some malware, trojan, viruses find it way into my laptop and infect my laptop?

Vegan/Vegetarian people more easily experience lack of omega-3.

Omega-3 is fatty acids play a key role in myelin production, and myelin is a highly organized insulator sheath that surrounds each nerve cell.

Imagine if a person lack of omega 3, than lack of myelin - that means his/her nerve fiber lack of insulator, it will pick up all the surrounding electric pulse signal and that might be the reason causing tinnitus.

from http://www.livestrong.com/article/474358-do-omega-...

"Each day, the millions of nerves that make up your nervous system send billions of electrical impulses that help maintain your health and support your day-to-day activities. One key component essential to nerve function is myelin, a highly organized insulator sheath that surrounds each nerve cell. Many nutrients from your diet, including proteins, vitamins and minerals, contribute to the health of your myelin, and omega-3 fatty acids play a key role in myelin production."

(note: I send this posting here because i believe some tinnitus is related to lack of certain nutrition and vegan/vegetarian people are more prone this tinnitus problem)

This noise is high frequency noise.

I used to hear this noise when I switch on the old TV (when i was a teenager)

But now i am old already and no more old TV but i always hearing this noise all the time and everywhere i go, in my bed room, living room, inside car (with engine off), inside hotel room....everywhere...

Is this because i lack of some nutrition? vitamin B12? omega 3?

(I am vegetarian and seldom consume egg, milk daily product).
