[7]Radiowaves heat nanoparticles and kill cancer tumors
[8]Kanzius RF therapy attaches microscopic nanoparticles to cancer
cells and then "cooks" tumors inside the body with harmless radio
waves could be in clinical trials as early as 3 years. The treatment
has been 100% effective in animal trials.

[15]The CBS news has an extensive 4 webpage feature on the technique.
An interesting aspect is that Richard Smalley initially thought that
the radiowave to heat up metal nanoparticle technique to cook cancer
tumors would not work. Richard's scientific intuition was that this
would completely fail. He was converted into being a believer when
proven wrong with successful experimentation.
This is relevant since Richard Smalley's intuition was that molecular
manufacturing would not work. This does not indicate that molecular
manufacturing will be successful, but it does show that Richard's
track record for intuition related to a successful or unsuccessful
application of nanoscale related technology is not 100% accurate.

[39]Wired reported that the Navy is funding a follow on megawatt laser
project to the 100 kilowatt solid state free electron laser project.
[40]I had previusly covered the progress and technical details of the
100kw laser project and [41]here
The Navy is pushing ahead with a five-year, $163 million dollar plan
make megawatt free electron lasers. So by the end of 2012 or the
beginning of 2013, the goal is to have a new megawatt laser prototype.
[42]Previous megawatt lasers like the Tactical High Energy Laser
(THEL)required hundreds of gallons of [43]toxic chemicals for each
shot. So a "mobile system" was eight cargo containers in size.
[44]There was also the airborne megawatt chemical based laser for
shooting down missiles.
[45]New navy ships could have electric generators and engines.
[46]Superconducting engines are 1/3 of the weight (69 tons instead of
200 tons) and half the size of conventional engines and are up to 10%
more fuel efficient at low speed A typical destroyer has 200,000
gallons of fuel (300 gallons per ton is 6700 tons of fuel).
[47]Existing nuclear powered submarines tend to have one or two
reactors in the 190MW range. The nuclear reactors for naval ships
range in size up to 550MW. A nuclear aircraft carrier can have eight
of the 190MW reactors.
Naval reactors are pressurized water, liquid-metal-cooled, or boiling
water types, which differ from commercial reactors producing
electricity in that:
Naval reactors have a high power density in a small volume; some run
on low-enriched uranium (requiring frequent refuelings), others run on
highly enriched uranium (>20% U-235, varying from over 96% in U.S.
submarines (They do not need to be refueled as often and are quieter
in operation from smaller core) to between 30-40% in Russian
submarines to lower levels in some others), the fuel is not UO2
(Uranium Oxide) but a metal-zirconium alloy (circa 15% U with 93%
enrichment, or more U with lower enrichment), the design enables a
compact pressure vessel while maintaining safety.
If this is to scale then the reactor and engine take up half the
nuclear submarines volume. With the reactor within a 33 foot hull
diameter and about 25 feet long for about 25,000 cubic feet of volume.
[48]Here is a site with a lot of details on naval nuclear reactors.
The navy nuclear reactors are about 1100 to 2250 tons.
[49]The OK 650B nuclear reactor.
[50]Nuclear batteries (Uraniam hydride reactors) could also be
developed by 2012 and could offer smaller power sources for powering
Megawatt lasers or new [51]railguns. A nuclear power source would
lighter be than an fossil fuel engine and fuel. The uranium hydride or
other liquid core reactors would be smaller than current reactors.
[52]Better solid state lasers will help enable space launches with
laser arrays.
[53]If the Bussard fusion system proves successful, then the world of
2025-2035 could have powerful interplanetary spaceships with
multi-Megawatt lasers and railguns.
