Hypersonic Weapons and Rockets

India and Russia have agreed to develop and induct a new hypersonic version of their joint venture 174 miles-range BrahMos cruise missile by 2015. The new missile will be known as ‘BrahMos-2’ and will have a speed of over 6 Mach (around 3,600 miles per hour) with a striking-range of 174 miles. NASA Hypersonic ProjectNASA …

Technologies that Would Change The Energy Picture

The Wall Street Journal has an article about five technologies that would change the energy and climate picture. Over the next few decades, the world will need to wean itself from dependence on fossil fuels and drastically reduce greenhouse gases. Current technology will take us only so far; major breakthroughs are required. * Space based …

Correcting Amory Lovins Again

Amory Lovins wrote an article on Grist primarily making the case that nuclear power is not economic and has a 30+ page pdf on the “Four Myths of Nuclear” This will be the first of a few articles where I show where Lovins is wrong. Firstly he talks about gross dollar or energy amounts. Those …

Nuclear Fuel Transitions: Higher Burnup, Thorium and More

Nuclear fuel burnup is measured in gigawatt-days per tonne and its potential is proportional to the level of enrichment. Hitherto a limiting factor has been the physical robustness of fuel assemblies, and hence burn-up levels of about 40 GWd/t have required only around 4% enrichment. But with better equipment and fuel assemblies, 55 GWd/t is …

Understanding Neutron and Proton Behavior in the C12 Nucleus

From a research paper: “Probing Cold Dense Nuclear Matter”: The protons and neutrons in a nucleus can form strongly correlated nucleon pairs. Scattering experiments, where a proton is knocked-out of the nucleus with high momentum transfer and high missing momentum, show that in 12C the neutron-proton pairs are nearly twenty times as prevalent as proton-proton …
