IIT-Roorkee engineers develop electric car prototype that needs ‘refuelling’ not recharging, say it won’t cost any more than your petrol or diesel vehicle.
India’s industrial output growth saw a 10-month low in June, with Index of Industrial Production (IIP) growing by mere 1.5% as against 1.9% in May 2025.
ACM Katre was 2nd IAF chief to die in harness. It was at a memorial lecture in his honour where IAF chief AP Singh revealed that India shot down 6 Pakistani aircraft in Op Sindoor.
Standing up to America is usually not a personal risk for a leader in India. Any suggestions of foreign pressure unites India behind who they see as leading them in that fight.
According to Alcoa, the world’s largest producer of aluminium, the best smelters use about 13 kilowatt hours (46.8 megajoules) of electrical energy to produce one kilogram of aluminium; the worldwide average is closer to 15 kWh/kg (54 MJ/kg). Worldwide production of aluminium in 2010 was 41.4 million tonnes
So aluminum is converted back to oxide (bauxite aluminium ore) that means again converting that to aluminum takes more electrical energy…
So what is the energy advantages… Is it range..
But transferring electricity directly from road is best option, SoC(smartphone processor) producer Qualcomm is working on induction roads…
In a land of superstitions, journalists and editors of even the so called respectable media houses cannot get things right. Nothing runs on water. Water is a very low energy molecule that one gets by burning high energy hydrocarbons or hydrogen. It is like ash or CO2 – spent byproduct of an exothermic reaction. What is commendable about this technology – fuel cells – is that although it uses electricity, it uses it very efficiently (with little wastage), inexpensively, and portably. It uses electricity for electrolysis of water to break it into hydrogen and oxygen. When the car needs energy to run, it recombines hydrogen and oxygen to form water again in the fuel cell, and releases energy as electricity instead of heat. This process loses less energy to heating of an engine. But the electricity to charge the car (which means breaking water into hydrogen and oxygen) can come from a coal thermal power plant, which is also polluting, but less polluting than burning petrol in a regular car engine.
Get your facts straight and educate the public instead of confusing them with mumbo jumbo that this car only needs water. No, this car also needs electricity.
Aren’t IITs famous for jugaad culture in name of R&D? In so many years, none of them have been able to produce any noble prize winner nor any life changing technology. But yes, if you want to learn how to deliver babies using Vacuum suction (as in movie 3 Idiots), or IITs are numero Uno.
They are nothing more than NRI robots producing factories..

A 44 yo Indian man from a village in MP ( I guess ) has already done it using water and carbide reaction . This is the best IIT can give ?
