| Helios Solar Powered Aircraft |
 |
Compilation of test flights.
Pathfinder Solar Plane preceeded Centurion.
Pathfinder turned into Pathfinder+ by
removing the original center panel and
replacing it with a panel that was about 48
feet in length. Centurion turned into Helios
Prototype, which turned into Helios and
Helios with a fuel cell. The difference
between Centurion and Helios prototype was
removing the center panel and adding 2 new
center panels. Helios flew with 5 pods and
had a full solar array. The fuel cell version
was made by removing the center pod and
replacing it with the fuel cell pod. That is
the one at the end of the video.

| Test Driving a Hydrogen-Powered Turbo Prius |
 |
The LA Auto Show isn't just about looking at
alternative fuel vehicle—today it was about
driving them too. West Coast Editor Ben
Stewart spent a few minutes with Quantum
Technologies and their turbocharged hydrogen
powered Prius. Yes we did say turbocharged
but no it won't dust your buddy's Camaro.

| H2O Car - Water Powered Car |
 |
http://www.genepax.co.jp/en/
Have you ever wondered why H2O/Water powered
cars have never been marketed by U.S
companies? Maybe the word OIL comes to mind!
Now the Japanese are marketing H2O cars.
Please don't tell me that America will be
buying H2O cars from Japan, when this simple
technology has been available for decades!!!

| The fastest human powered bicycle |
 |
The fastest human powered bike world record
was set in Oct, 2002 at 81 mph (130km/h) by
Sam Whittingham from Canada. Since the
record was set, it is still remains unbroken.
Sam owns a custom bike shop in:
http://www.fortebikes.com/
The bike was designed and built by Georgi
Georgiev (Varna Team).

| DIY: How to build A High Powered Burning Laser pointer |
 |
Don't want to build one? Buy a 200mW one for
$44 here

***UPDATE***
If you really want to build a laser, please
don't use this tutorial. I made this video
when I was younger and I didn't know much
about lasers. I will have a much better and
easier tutorial up in a month or so if you
can wait. Until then check out
laserpointerforums.com for some great
tips/tutorials on building lasers.
If you are going to use this tutorial anyway,
the circuit used in this video is a BARE
MINIMUM. Although the one I made in this
video still works fine to this day, you will
probably want to add a small capacitor
(anything over 10v 16uf is fine)in parallel
with the diode to even out any voltage spikes
from the battery. To build a well regulated
circuit check out www.laserpointerforums.com
for some great, easy to build, current and
voltage regulated circuits for lasers.
One thing to note is the prices of the diodes
have jumped from $13 to $19.50 but you can
buy the diodes off of sales.stonetek.org
If you need more help you can find me and a
bunch of other people that can help you on
Laser Pointer Forums and Spectraforums!

In this video I show you how to build a
homemade high powered burning laser.
Parts:
You can get 100ohm potentiometers off ebay
for pretty cheap
You can get you switch and battery holders at
any radioshack
You can get your laser diodes at
laserpointerforums.com for less than half of
the price of pulling them from a DVD burner
(and a heck of a lot easier)
You can get AixiZ modules from Ebay Seller
aixiz_lasers
A few tips
-DO NOT LET ANYTHING SHORT!
-When you have turned the pot so the
brightness turns high, don't even think about
turning it more to make it more powerful. If
you do that the power will go from 100mW+ to
.1mW and your diode will be screwed
-buy more than one diode cause they can break
by simply touching them sometimes, too much
current to the diode or a ton of other things
so you will be safe buying more, and if you
have extras build more modules and sell them
to your friends for even more fun! (go ahead
and charge $100 for them so you can be rich)
-Buy goggles for these things! Goggles cost
around $40 and are easily worth it, your eyes
are worth more than $40 and if you get hit in
the eye by this thing without goggles on,
you're screwed.
