It needs 1 to 2.5 watts of power, which is supplied by a small, off-grid solar PV system on the balcony of the author’s home. Typical for off-the-grid renewable power systems, energy storage is limited. This means that the website will go off-line during longer periods of cloudy ...
Accidents like that didn’t happen much anymore, but Martians seemed to have this cultural memory of being one mishap away from suffocating or being carried off by sandblasting winds. I found what I needed on the depot inventories. I found where the items were located. I could absolutely do...
Antenna arrays can be used to increase system capacity in PCS networks by supporting multiple co-channel users per cell in receive and in transmit. We prop... S Talwar,A Paulraj,M Viberg - IEEE International Conference on Communications 被引量: 30发表: 1994年 Semiconductor memory device for ...

At least 99.9% of physicists believe the theory of gravity, and the heliocentric model of the solar system. The debate is over. There is no doubt that we can send a manned (and woman-ed) mission to Mars. Some "skeptics" say it can't be done. They are...
Promoters of quack medicine sell various pills guaranteed to improve your memory or your sex life. Green energy is quackery too. It is promoted by green organizations like the Sierra Club. At one time the Sierra Club was a harmless club of backpackers and bird watchers. But it ...
Put any window glass over the front, so the sun's energy gets magnified, and run water through the system using a small pump. We built one of these years ago, to heat a huge swimming pool, and it was an awesome project with great returns on investment. The trick is to make the ...
