Don’t tell anyone, but Doug Ausenbaugh has built an underground drug farm—in bucolic southern Indiana, no less. It’s cleverly cached in an old limestone mine near the hamlet of Marengo. There, carefully cultivated stalks flourish under the glare of artificial lights and the rainlike spatter of drip irrigation.

Car engines have been governed by computers for years, but Honda’s iGX440 (honda.com) is the first power-equipment engine with a microchip. The electronically regulated iGX440which will show up in lawn mowers, water pumps and pressure washers later this yearruns at a constant engine speed even under changing loads. Thick grass usually causes mower engines to slow, bogging down whomever's pushing the machine, but the iGX440 maintains speed, and thus power, by giving the engine more gas and manipulating ignition timing.
When a former Russian major attacked the combat utility of Americaâ€™s aircraft, PopSciâ€™s radar homed in on the debate

In a heated wartime editorial, PopSci rebutted highly publicized claims that U.S. planes were inferior in speed, range and armament to enemy fighters—claims made by Major Alexander de Seversky, a WWI Russian pilot turned U.S. aircraft manufacturer. “It would be an insult to the dictionary to designate as ’military’ craft so deficient in the basic qualities necessary for combat,” he wrote in his 1942 book Victory through Air Power. We argued that each plane in the U.S.

Devalued stocks, raging unemployment and weakened national pride plagued the 1930s, but PopSci escaped the Great Depression with a focus on fun inventions. A ride that “gives thrill seekers topsy-turvy sensations, comparable to those of looping the loop in a plane” graced our May 1934 cover, half a century after the roller coaster first appeared in American amusement parks. A giant steel arm swung this four-passenger car like a pendulum until momentum took over, hurling riders around a full loop.
Saabâ€™s BioPower engine gives ethanol a kick in the pants

With all the buzz about hybrids, it´s easy to ignore our homegrown alternative fuel: ethanol. Clean-burning and infinitely renewable-we´re talking grain alcohol-ethanol is dear to environmentalists and economists alike. The standard 85/15-percent ethanol/gasoline blend (E85) is widely used in Sweden, but there are only 313 E85 fueling stations in the U.S.
