NASA, Google Award $1.35M For Ultra-Efficient Electric Aircraft

coondoggie writes "NASA today awarded what it called the largest prize in aviation history to a company that flew their aircraft 200 miles in less than two hours on less than one gallon of fuel or electric equivalent. Their aircraft is the Taurus G4 by Pipistrel-USA.com. The twin fuselage motor glider features a 145 kW electric motor, lithium-ion batteries, and retractable landing gear."

    1. Re:Interesting as a crowdsourcing experiment by wierd_w · · Score: 1

      This is a fundemental problem, often erroneously addressed as an education problem.

      Hear me out here:

      The training an engineer gets revolves around already known points of data. Things like the shear of a sheet of 2025, or the total energy in 1 liter of octane, etc. This is what an education gets you.

      Using this already known information to produce provably airworthy craft with minimal risks and unknowns is the staple of commercial avionics.

      The application of what is already known, to devise new and untested approaches to old problems (and as such, the extension of knowledge) has 2 homes: the high priced university, which has a financial motive to patent encumber all new knowledge to improve their financial standing, and the garage tinkerer, who has to operate under the sword of damoclese held aloft by established commerical and government interests.

      Sending kids to school to become engineers will greatly increase your engineering talent pool, but that alone will not propell you to the forefront of innovation. Trained is not the same as inspired.

      The reason why the US is stagnating on the engineering frontier, and losing relevence as an industrial innovator is because the leadership of the US has enacted policies and foriegn trade deals which have the active consequence of stifiling that very characteristic, and does so at nearly all levels.

      1) a poor educational system that emphasizes social welfare and political correctness over such obviously less important things as science and math, which creates future generations who lack the fundemental educational backgrounds to even attempt such innovation even with government and industrial blessings. When you diminish the number of minds properly trained, you exponentially diminish the number of truly inspired people who could push the state of the art ahead. (Eg, imagine if einstien had ended up working a dead end job at McDonalds, due to a substandard education.)

      2) lobbyist activity has managed to dupe the government into believing that private industry is the source of innovation, and has scored such private industry some very powerful tools to actively suppress the true sources of innovation. Such tools include draconian intellectual property laws, and revolving door politics.

      3) falling standards of living and base levels of education have forced institutions of higher learning to continually raise the costs of tuition (due both to greed, and due to increasing base costs to meet minimum student performance ratings to maintain accredation), which reduces the available resources with which student researchers would be able to perform said research, leading to subpar and marginally effective research projects, and a vicious cycle of cuthroat academic politics as said researchers gouge each other's eyes out to scramble and claw for every scrap of funding they can get.

      3) indulging in modern McCarthyism, such that anything out of the ordinary being created in a garage is treated as a potential terrorist plot if reported by ignorant people, complete with all the life changing consequences of such social abberation such as being blacklisted in one's chosen vocation, or even jail time.

      4) the implied and over-reaching threat of corporate litigation over silly things (like making a device with rounded corners), or of government smackdowns and red tape for failure to secure "proper permits", where the bureaucratic maze to obtain such permits is byzantine and intractible.

      Taken together, the pace of innovation has basically ground to a screeching halt in favor of milking the status quo, and attempts at stifling real innovation in competing countries as they take advantage of the laxity of the current US leadership.
