Exploring the Heliosphere: Insights from NASA’s SHIELD Project

13th May 2026 I thank the American Institute of Physics (AIP)  for organising an exceptional talk by Dr Merav Opher on the SHIELD (Solar wind with Hydrogen Ion charge Exchange and Large-Scale Dynamics) project, which she is heading at Boston University in collaboration with NASA and several other institutions. It was a great privilege for me to learn from one of the leading plasma astrophysicists about this highly complex interdisciplinary initiative.  The SHIELD project aims to implement a ‘digital twin’ of the heliosphere, the bubble surrounding our solar system created by solar wind from the sun travelling supersonically with velocities in the range of 400Km/s.  This protective bubble,which is much larger than our solar system, is responsible for shielding nearly 70% of harmful cosmic rays.  The motive behind creating a digital twin emerges from the fact that the plasma characteristics of the heliosphere are quite different from lab plasmas and interstellar plasma...

bhū Travel Council and Kalamaki Travel Forge Partnership for Sustainable Global Tourism

Extremely happy to announce that the bhū travel and tourism council has signed an MoU with greek travel agency Kalamaki Travel.Established in 1989 Kalamaki is one of the oldest, continually serving travel agencies on the island of Crete that has been delighting visitors for decades by creating some of the finest travel experiences. Our agreement emerges as a response to one of the toughest challenges facing independent travel agents today — consolidation by online travel agencies with immense marketing budgets making it impossible for small business owners having neither the technology nor the manpower, to compete with them.  With our agreement we have decided to take a bold new direction that places emphasis on cooperation between independent travel agencies & creation of new business opportunities rather than clashing over shrinking markets as more traffic is routed through global distribution systems.  By placing emphasis on domestic tourism, building new it...

High-Exergy power generation via the AJ cycle: A thermodynamic analysis

ABSTRACT Traditional thermodynamic systems are constrained by Carnot efficiency limits, restricting the conversion of low-grade thermal or cold energy into useful work. This study explores a novel approach to overcome these limitations through combined heat (or cold) and power generation, enhancing overall system efficiency. Central to this approach is the proposed AJ cycle engine , a low-temperature-differential, five-process thermodynamic cycle capable of efficiently converting thermal energy into mechanical work with high fuel efficiency. The AJ cycle leverages adiabatic expansion, isochoric and isobaric heat exchange, and controlled heat addition, with fluid circulation aided by pumps and heat exchangers, enabling compact, high-exergy thermomechanical operation. By allowing high fuel efficiency even at modest mechanical efficiency at low temperature differentials and the possibility of miniaturization, the AJ cycle paves the way for versatile applications, including small-scale pow...

Decentralizing palm oil for global stability & seeding high tech industries with waste biomass

April 15 2026  I thank the global landscapes forum for inviting me to a digital conference on sustainable palm oil production. The panel discussion featured several leading experts in the industry brainstorming on what it would take to induce a paradigm shift in the palm oil production and how it could be financed.  Palm oil fulfills nearly 30-40% of global vegetable oil demand. It finds application in cooking,cosmetics,health and in several other related industries. Despite its huge demand roughly 80-90% of palm oil production is centred in South East Asia. Not only does this concentration create a significant geopolitical risk it also prevents efficient utilisation of land resources that could lift millions out of poverty.  Africa and LATAM present immense potential to diversify the production especially as cultivable land becomes more expensive in the SEA region. Yet there are several factors that could potentially be holding investment back. One reason is quite simple...
