My wife's daughter is a licensed cosmetologist here in Virginia Beach. She would like the hand-held blow dryer she uses constantly every day to be sans power cord, because the cord frequently gets tangled on either the chair or the customer while the dryer is being used. So, she asked her husband to "invent" a cordless dryer.
Since we are visiting with them for Christmas, he sought my advice on how to do this. I examined the dryer and discovered it is rated 1500 watts with 125 V AC power. I asked how long it takes, on average, to dry and style hair. About fifteen minutes is minimum, but some take much longer... thirty minutes or more if there is a lot of hair to dry.
So, I figured, no problemo. I just need to fit an inverter and a 1500 watt-hour battery in the handle... Not! Her hands aren't that big.
So, Plan B.
Wait! There is no Plan B.
Does anyone have any ideas on how to make a cordless 1500 watt hand-held blow dryer for hair? Should weigh a little (two pounds?) and do a lot (run continuously or at least fifteen minutes). I am thinking something along the lines of Tesla wireless power transmission, but I can't seem to find Nikola's notes on exactly how to do that. Plus, the salon patrons must not notice the method of wireless power transmission... no arcs, sparks, tingly sensations, or odor of ozone.
Best I've been able to come up with so far is a handful of cylindrical super-capacitors stored in the dryer handle and a really fast charging stand. You just swap out a depleted capacitor for a freshly charged capacitor as necessary... but maybe every two or three minutes is my SWAG (Scientific Wlld-Ass Guess) on this. Maybe a graphene supercapacitor would work, if the gravimetric energy density is large enough... the weight must not cause carpal tunnel syndrome in the user.
