You don't imagine, how large part of world, which have at least two months year, with near 90% fall of solar energy. And they have to use traditional energy sources, or buy energy from neighbors.

Overall, making business is simple, just make few things: 1. get some product (it is not really important, what is it, could be even garbage from attic, or old things); 2. make view, who could pay for it; 3. make simplest ad; 4. talk with p

Just do it. This is most popular mistake of people, to think about business, or to discuss it, instead of do. Because idea is nothing, but implementation is all. History know many fails with exceptionally good ideas, and much less number of

Most probably, no. - Turbine wheels noise is usually shielded by enclosure, and exists other powerful sources of noise, for example, intake. Yes, much noise of heli create intake air.

We don't really know, what used on military submarines, because real photos of their props are top secret. On civ subs, as I know, main driver of choose is just cost, so usually they use conventional cheap designs.

Yes, You are absolutely right. Anybody could try any shape for scientific experiments, but sell copies and distribution of 3d models prohibited.

People in Ukraine print small props. But conventional design. For small electric engines good enough.

BTW, because autos special requirements, there widely used turbo-compressors, but they are rarely used in marine motors and not too distributed in air. This is because, turbine only eat power and does not give anything at low rpms, only eff

UNLIKE for ground vehicles, marine and air. - From tutorial for auto engineers: "more than 90% of time, auto engine working at fast switching conditions, and extremely low load, near zero", vs marine (and air), where prop does nea

Unfortunately, not fair comparison "Although we have every confidence in boattest.com’s findings, they were only performed on one boat, and unlike Motor Boat & Yachting’s sea trials, its tests are paid for by the manufacturer"

Most people are capable to do about 500-800W for long time (30 minutes or more), and up to few kilowatts for short time, 1-3 minutes.

by simne 4y ago
Kilowatt is ~ 1.3 hp, so 600W = 0.8HP. But, here important, that electric engines have much better torque on low rpm, even exist electric engines which give high torque just from zero. Also it is typical, to overdrive electric engines for s

Unfortunately, practical EISA was too expensive, to compete with MCA. MCA was completely defeated only when happen PCI. Because of this, some time exists Vesa, and some other exotics.

You are partially right. It is really hard to write portable C++ code of small projects, because strings are different in nearly all major platforms. But if You tied to one platform, platform specific strings, usually, are good enough for h

Oh, yes. Have touched Ada in VHDL (using Ada declarations syntax), declarations in Ada are very long, but extremely powerful. Have not seen any comparable in popular languages (except Modula 3, which is for same domain), nearest as for me,

Haskell is too special, to be used in typical large project. But in real projects, are in wide use other pure functional langs (trying to write most popular first): - Erlang (telco, finance) - Lisp (finance, CAD) - Scala (basically universa

Properly used formal verification, could make unhackable software, but expensive, because of this used rarely. For example, I know people, who made formal verification of their soft for power plants.
