If you make the switch to an electric car today, you can capitalise on all the financial benefits of emission-free driving and save up to £2,605 in your first year and £570 each year after that until 2025. Is my car taxed? How to tax your vehicle It’s illegal to drive ...

Townes and Arthur Schawlow, then at Bell Telephone Laboratories, wrote a long paper outlining the conditions needed to amplify stimulated emission of visible light waves. At about the same time, similar ideas crystallized in the mind of Gordon Gould, then a 37-year-old graduate student at ...
Founded in 1937, Volkswagen has survived wars, countless cycles of boom and bust, as well as the infamous 2015 emissions scandal in which it admitted that many Volkswagen diesel engine cars sold in America had built-in software that could detect when they were being emission-tested and could a...
For a highway concession, issues of sustainability (low-emission construction and maintenance), resilience (quality of infrastructure and withstanding of exceptional situations), life-cycle durability, and so forth, are some obvious examples of such procurement. The above means that the public client ...

And those are "Emission Nebula Filters", not light pollution reduction filters, though they do work that way for emission nebulae. What about all those "medium band" filters (30-50nm bandwidths in the blue green)? Well, they are more effective than broadband/LPR/CLS ...
It’s Graduated Vehicle Excise Duty – or car tax –and is a charge on vehicular emissions, with the least polluting vehicles paying less or even nothing. If cyclists were to pay VED, they would pay £0, the same as low emission cars. ‘Road tax’ was abolished in 1937. ...

Radioisotopes, or radionuclides, are unstable forms of elemental matter either man-made or found in nature. They all undergo a spontaneous process of radioactive decay through the emission of alpha and beta particles, gamma rays, and more. All of the elements on the periodic table with atomic ...
