Greenhouse Gas Emission Reduction Potential of Electric Vehicles (4-Wheeler) Currently, the #indian #electricalvehicle #industry (IEVI) has gathered momentum due to a rise in #crudeoil prices and support provided to the IEVI by #governmentsupport . People are readily adopting Electrical Vehicles (EVs), intending to reduce monthly expenditures. However, there is still a need for advancement in infrastructure facilities, including #greenenergy supply, #chargingstations , and highly efficient charging systems for the mass shift from internal combustion engine (ICE) vehicles to EVs. In 2019, EVs represented only 0.1% of total #fourwheeler (4W) light-duty passenger road vehicle sales. When the life cycle #greenhousegas (GHG) emissions compared the 3 Nos. of most popular brands of the available EVs with the available counterpart light-duty passenger road vehicles based on Petrol (Spark Ignition), and Diesel (Compression Ignition), the picture becomes hazier. The green-colored positive

Shallow Aquifer - Weakening Foundation Significant Cracks on Building Structure  During the testing of our newly developed chemical for waterproofing, we observed significant cracks in the basement of the newly constructed buildings in nearly all the metro cities of India. On investigation, we found that these buildings or their neighbouring buildings have incorporated Ground Water Recharge Wells. On further investigation, we found that the said Ground Water Recharge Wells were not been designed by competent personnel. The management has given the contract to the lowest bidder. Note: Ground Water System is very complex and needs an expert to design a sustainable Ground Water Recharge Wells. How are these major basement cracks related to Ground Water Recharge Wells? During the design of the Foundation, we all came up with the terminology Uplift Pressure or Hydrostatic Uplift, defined as an upward pressure applied to a structure that has the potential to raise it relative to its surround
