Engineers are developing giant solar-powered flying wings that are remote-controlled and designed to remain aloft athighaltitudes for weeks, months, or even years -- nonstop.
Yet no matter how tasty the treats these top-flight chefs devise, diners athighaltitudes may not be able to appreciate the culinary wonders on their trays.
The authorities have been taken aback by the numbers who are insisting on staying put athighaltitudes through the winter perhaps 350, 000 in remote villages at above 1, 500 metres.
Today, the best that can be said is that the extent and duration of future EMP-induced blackouts would depend on whether the emitter generates a small or large pulse, and whether it is detonated at ground-level or from highaltitudes.
