AFOSR and NASA Launch First Test Rocket Fueled by Aluminum-Ice Propellant

Green Car Congress

The Air Force Office of Scientific Research (AFOSR) and NASA recently launched the first test rocket using an environmentally-friendly, safe propellant comprising nanoscale aluminum powder and water ice (ALICE). They found that the pressure exponent for ALICE was 0.73, which is approximately a factor of two larger than Al/water mixtures.

USC chemists develop catalyst for reusable, air-stabile ammonia borane dehydrogenation; potential for on-board hydrogen storage

Green Car Congress

Importantly, the catalyst is robust, delivering several cycles of dehydrogenation without loss of catalytic activity, even with exposure to air and water. Conley, Denver Guess, and Travis J. The new catalyst liberates more than 2 equiv of H 2 and up to 4.6 system wt % H 2 from concentrated AB suspensions under air.

How Engineers Can Help Protect Earth From Worsening Climate Change

Cars That Think

The microbes and minerals in soil systems regulate water, cycle nutrients, filter pollutants, physically support plants, and sequester greenhouse gasses. Climate change also causes indirect effects on health, such as food and water insecurity, the spread of climate-sensitive infectious diseases, and population displacement.
