new battery

Last year Toshiba developed a new lithium-ion battery that can incredibly be recharged to 80% capacity in one minute. That is right one minute and it is recharged to 80% capacity. That is extremely fast especially when we consider that current lithium-ion batteries take about an hour to be recharge to that amount; that is a 60 fold improvement. Not even considering the increased energy capacity and other improvements of this new battery, the rapid charging ability is already enough to make this battery worth while, it is just an unbleiveable improvement! Unfourtantly even though it has increased capacity it does not seem that it has increased capacity in any vast amounts when comparing it to the recharge time improvement; however it does boast a 600mAh energy capacity. This battery real benefits can be found in its life span and usable in almost any temperature. This battery can operate in very high extremes of temperature; it can discharge 80% of its capacity at minus 40 degrees which happens to interestingly be the same in the Fahrenheit and Centigrade scale. Sufficient to say it is very cold and as anyone like myself; who has left rechargeable batteries out in the cold knows this will be a very helpfully feature. In addition, they say it losses only 5% of capacity at temperatures as high as 113 degrees Fahrenheit after 1,000 cycles; meaning that the battery is very high life. Unfortunately we may not see this battery in laptops right away Toshiba seems to be trying to market it more towards cars and locomotives at this point, however this technology should eventually be incorporated into laptops I would imagine, we will see it in them in the not to far future.

old bridge

Well the second phase of the Jamestown bridge demolition happened this past Thursday at 11:27am. However this time there were not as many people there were no dignitaries and no governor. This one was supposed to be louded, but I doubt it was. For the first demoltion I was quite a distanse away off of Ferry dr. in Saunderstown and it was really loud. However this second time I parked my car and followed a path where I came out on the back side of the bridge (meaning my view or the old bridge was blocked by the new bridge) then I walked down under the new bridge and the remianing part of old one and sat all of 20 yards away from the bridge and the first one sitll sounded louder I though. This demoltion took down more footage of bridge 2,000ft as where the first only took down 1,000ft of bridge, however the first demolition took down the center span with which had more height and assumely had more steel and weight, alhtough it may had taken more explosives to take down this portion.

When you talk to someone who remebers when the old bridge was built in 1940 they will tell you that this demolition is a major hisotrical event, and will expess somewhat of a sadness to see it go. However the old bridge has long outlived it’s usefulness and has not been used since the new Jamestown Verrazzano Bridge open in 1992. The old bridge was a scary bridge with the wind would blowing the car and the gates n each side alloweda view through them stright down to the water just added to the uneasyness.

Metal Storm guns
Wow Metal Storm guns are crazy is crazy. It can fire thousands of rounds a second, hence the name metal storm. They even have a pistol type gun that can fire 3 rounds before it even recoils, making it extremly acurate atlhough I do not think it can fire many more rounds that a conventional gun it can fire rounds much faster and no jam.

The secret to these metal storm weapons is that they do not use conventional firing mechanism, and therefore have very few moving parts. Metal storm guns use an electronic ignition system so bullets in the guns are just lined up right behind one another, so even if a gun does jam the next bullet behind it will push the jammed bullet out. The metal storm gun can also fire 250,000 grenades a minute.
