The Magnesium Injection Cycle engine is powered without using fossil fuels.
Power is generated by the chemical reaction between magnesium and water, which produces high-power steam and hydrogen. The hydrogen is burned at the same time to produce more high-power steam, and the two steam sources power the engine. The new technology produces no carbon dioxide or other harmful emissions and the only by-products from this reaction are water and magnesium oxide. The magnesium is separated from the oxide through a solar-powered laser process and is reused over and over again as fuel. This clean energy cycle, which is supported by solar power, has the potential to reduce dependence on fossil fuels, and could bring about a paradigm shift in the way future energy needs are met.

Development of alternatives to gasoline and "dirty" diesel power can be fun.

Some recent records and an upcoming attempt:

Ford Fusion fuel cell powered car, 207.3 mph.
E85 powered Viper, 220.7 MPH.
Dieselmax, 317, 328, and 350 MPH in one week.
Steam car set to break Stanley Steamer's 1906 record of 127.65 MPH; shooting for 200+ MPH

Greg Kolodziejzyk, who holds the 24 hour bicycle record of 1061 km in 24 hours, set a human powered boat speed record: 173 km in 24 hours. Greg is planning an Atlantic crossing in a pedal powered boat in 2008.

"Our modern sedentary lifestyles are putting our kids at risk at being the first generation that will have a life expectancy shorter than that of their parents. My mission is to get kids active again. Human power is the power from 'WiTHiN'".Greg Kolodziejzyk.

Maybe you should also post this in the Propulsion section, nice link.

I posted it in several of my regular forums already.

Hey hey !

Check out this bathroom................

Can you find the boat ?

I know it's hard... just try though !

A couple more to just stare at... Click each picture to enlarge it.
The grey one with the two circles... look at the dot in the center. Now, slowly... move your head closer and then reverse it... back up and watch what happens to the circles.

The other one just stare at for a moment.

Here's an example of actual sidewalk art... chalk art.

Can you find the waterfall in the picture of the two girls...

How'd you like to be followed around by these all day long ?

Computer fans:

With cooling demands constantly increasing, tubeaxial fans are becoming incapable of meeting today’s tougher needs. The fan speed for a tubeaxial has to be increased to meet the current flow and pressure requirements, but this makes it impossible to meet power and acoustic goals. The solution—diagonal fans from ebm-papst.

Hovercraft model lift fan possibility?
