anything in that chemical family does, sodium, potassium, cesium, etc...

We flushed it. :o

did anyone else see sportscenter(tsn) tonight?  They did a segment on a new product called therma blade.  The therma blade endorser said its the bigest revolution in hockey equipment in the last 100 years.  the blade of the skate is actually heated, this reduces friction up to 40% making for longer, smoother glides with less effort that results in more speed.  Its endorsed by Gretz, he said that he the therma blade as being a part of the nhl in near future.  A side note too, they had the blade on a pair of custom v12's with #99 on them, like they looked sweet....

One of my powerskating teachers got to try them out about 2 years ago.

But she said that you plug them into the wall and were on Tuuk holders so i dont know if its the same thing.

I guess that you could heat your blades on the bench and then skate - the extra glide wouldn't last long though! As for powering them, you could possibly set them up to only carry 15 minutes of charge, and charge on the bench between shifts wirelessly the way they power some laptops. I think they use some sort of induction system on the lap tops. I'm not sure if you'd be able to charge them quickly enough though. Just my ideas on how it could be made to work.

i wonder how much it will weigh and if it will be balanced inside of the holder(if it goes there) ...

and i cant wait to hear...

Coach: "Jimmy I need you to go out now. Its the last minute and we're down by 1 on the powerplay."

Jimmy: "Coach, I can't my batteries ran out!"

Just a little research:

"t-blade's gliding friction is approximately 40% lower than conventional systems', making it the fastest blade ever!" - t-bladehockey.com

"t-blade is the lightest ice hockey blade system on the market worldwide." t-bladehockey.com

Opinion:

now granted... i use t'blades so im gonna be a little opinionated here without anyone having tried this therma blade but... it has to be rather heavy (by heavy i mean in modern high tech hockey equipment terms) considering theres a battery and heat equipment on/in the blade... but if both blades claim to cut friction by 40%.. in my eyes the t'blade would be the better buy with my prediction of it being lighter unless you dont like the changable blade part about the t'blades

And, as for biggest revolution in 100 years (im not implying t'blades here) im not too sure of with the OPS and new skate technology YET but well see.

I've actually seen these things in real person and they are a lot lighter than you think. To develp them, they used Tuuk holders and then proceeded to make their own design. I've only seen the protypes with the Tuuk and as I said, they weren't overly heavy. They have a switch on them to turn them on and I have not seen this but according to my co-workers, the designer developed a charger made from Jofa step-in guards.

Batteries is your skates is a joke. Think about it. YOU HAVE A BATTERIES IN YOUR SKATES!! This is the saddest thing I have ever heard of. Why not put little rockets on the side of the skates and some little flashing red lights on the back of the skates that says "you suck" or something.... Thats' it, I'm putting fricking Lazers on my skates. I don't care if Greatzky put his name on it, and I'm Canadian. This is stupid. I know it's a slow news day so I have no problem talking about this but come on..... I've been waiting to cut up something dumb like this for awhile cause I own T-blades and can't cut them up Happy smiley

We watched a video in my AP chem class of people throwing magnesium into a lake. It was awsome. At firsti t was just a small amount, but at the end they threw in two paint cans worth of the stuff to make a beautiful explosion.

I have to say something about t-blades. I seriously doubt they reduce friction by 40%. Has their been independent studies, or are you just believing what the company is saying.

I would think the thin blade would conduct the cold, rather than create more heat. Just think, what freezes faster, a shot glass of water or a 5-gallon bucket. I would think the cold ice would cool the thinner t-blade quicker than a heftier steel blade.

Still if someone has a study, not conducted by t-blade company, I'd be interested in seeing the results.

Speaking of speed, I use a special compound here at the shop that increases speed big time. It's kind of like waxing skis, but it's not a wax. It's a friction reducer. It has to be ground in by a skate sharpener. It lasts 2-3 skates. I charge $1 extra for it. Customers love it. We've done test after test, blind tests, triple blind tests, put it on one skate and not the other, every imaginable test one can think of using real skaters playing hockey. It improves speed significantly. Some don't like it because they say it makes the skates go too fast. It's not a scam or propaganda. When I first started offering it, I gave it away for free to about 100 customers to get some feedback. The response was amazing. Then the word spread quick, now I have them and hundreds more hooked. It's like a drug, they have to have it. :-) Once you try it, you have to have it. The best thing is it's a low cost way to get more speed out of your skates.....batteries???

I guess you give the answer on your own: A shot glass of water also HEATS UP more quickly than a 5-gallon bucket. Think about it this way: Both blades (reg and t'blade) will have the same temperature when you step onto the ice (they will most likely be the same temp as the surrounding air). Then, once on the ice, the friction created by gliding creates heat during each stride. The thin t'blade (=shot glass) will heat up faster than the solid metal reg blade (= 5-gallon bucket). Of course, once you stop skating (e.g. when sitting on the bench), the t'blade will drop back to surrounding temp faster than the reg blade does.

I use t'blades because I can't get a good sharpening around here. In my experience coming from Tuuks the glide is significantly better on t'blades. That being said, as soon as I have the money, I'll get a portable sharpening machine so I can finally sharpen a regular blade to my gusto. I am very picky about my edges and while t'blades provide consitency they become expensive when you change them every 4 to 6 icetimes (like I do).

Once I have a sharpening machine I'll come back to you about that special treatment (provided it can be applied by an unexperienced sharpener like me and on a basic portable sharpening machine).

Dave, I think we are both right, however what we don't know yet is if the "shot glass" is cooled more by the ice or heated more by the friction.

I concur t-blades are great if you don't have a good sharpener nearby. If you do, I think in the long run t-blades will cost you a fortune, compared to conventional sharpening.

When I was in jr high a bunch of my friends and I stole some magnesium. We filled a big green garbage can halfway with water and hauled it out to the middle of the gravel soccer field. We taped some magnesium on the outside of a tennis ball and chucked it into the garbage can (from about 50 feet out). It was possibly the most spectacular and stupid thing I'd ever done.

LOL not in NYC where a conventional sharpening costs you around 10 bucks (as I've heard).

From my understanding, ideal ice temp is 14F/-10C. If this thing keeps the blade at 4C, it has to add 39F/14C to the blade (probably a little less, because gliding friction will add some heat too..) I don't have the time to calculate it now, but I'd guess that it doesn't take too much power to add about 10C to a small quantity of stainless steel..

same here... it was either t'blades or drive an hour to get a sharpening i could stand up on..

It's 6 in Queens. Manhattan could be another story.

Also, since when does ice fit into a shot glass?

Here is the info on T-blades:

"When you skate frictional heat is produced. With a conventional blade system this heat is lost, because the steel can not absorb any of it. The resin a t-blade runner is made of however, can store this frictional heat and the thin steel band heats up by up to almost 4°C. This, by the way, is what we call the thermo-effect which gave t-blade its name"

granted... but have there been any studies on these new blades.. arent we just taking what the company is saying about them too?

plus what melts faster? a shot glass full of ice (which would simply break the shot glass if you froze water in there ;)) or a 5 gallon bucket?

-------------------------------------------------------------------------------------------------------------

skate sharpenings around here cost $6.50 USD and they suck except for one place that is an hour drive there and back not including if theyre busy... thats why i converted to t-blades

I recently corresponded with a chemist/physics prof and this is what he had to say about t-blades vs regular blades:

Question: All variables being equal (weight, stride length, ice temp, etc, will the thinner blade have less friction and the skate go faster?

"No. All variables being equal, they will perform the same. Even if your blades are red-hot when you start skating, it won't take them very long to reach exactly the same temperature as the ice. Of course, the thinner blade will thermally equilibrate faster because it will hold LESS heat than the more massive blade.

The limiting speed of the blade will be determined more by the interaction

of the edge with the ice (sharpness, straightness, etc.) than by how much

material there is between the edge and the boot, or what the material is

(metal or plastic)."

The manufacturer of the thin blade claims that because it is thin it retains the frictional heat better than regular blades, thus melting more ice under the blade which acts as the lubricant for the skate to glide. They claim 40% less friction.

"Frictional heat is negligible. If there was significant friction the

runners would drag, not run. If the ice is being melted by heat, one should

expect that the heat would be lost to the ice as the blade moves along and

encounters fresh ice to melt. Skating works precisely because the physics

almost eliminates the friction.

The manufacturer is trying to get people to buy his product, which is a

little more complicated than the competitive product and presumably more

expensive. You could almost predict that he would try to emphasize some

imaginary advantage his product has, even if he has to resort to bad science

pitched to a consumer who doesn't know the true science behind how it works.

The manufacturer is either a fool (who doesn't understand how his product

works) or a charlatain (who is deliberately lying about how his product

works). It is extremely unlikely that someone could build a successful

business that is based on a misunderstanding of how the product works. You

do the math."

Question: I would think the opposite would be true,

with little mass, the thinner blade would be colder. Conducting cold from

the ice?

'Cold' does not get conducted. Cold is the deficiency of heat. Heat is

energy. Heat is what gets conducted."

If the blades both start out warmer than the ice, at the same temperature,

the thinner blade will lose its heat to the ice FASTER because it has less

heat (energy) to lose, in proportion to the masses of the metal of the

blades. Basically, once you start skating, you are running ice-cold water

(and maybe even a little colder) across the sharpened edge of the blade

continually. How long do you think you can do that before the blade cools

down to the same temperature as the ice water? I would wager less than 1

minute.

Bottom line, skating works because of the physics of ice under pressure,

not because of heat."

There you have it. I'd be interested in t-blades research concerning the 40% friction reduction. Yea, yea, before I get jumped on, I do think t-blades are great for those who can't get a good sharpening, I just don't buy the fast speeds because of the "thinner blade".

Cheers, I've got a shot glass to empty!
