Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electric load without interconnecting man made conductors. This concept of transmitting power without using wires i.e., transmitting power as microwaves from one place to another is in order to reduce the transmission and distribution losses. This concept is known as Microwave Power transmission (MPT). The percentage of loss of power during transmission and distribution is approximated as 26%. The main reason for power loss during transmission and distribution is the resistance of wires used in grid. According to the World Resources ...
Desalination of seawater is the only possible solution to the current water crisis. Increasing populations will require more and more water every year. Water levels in aquifers throughout the world are dropping because man is consuming the water faster than it is replenished by nature. Drought conditions in many areas exacerbate the problem.
Currently the desalination industry is focused on large desalination systems. The predominant desalination technologies are Reverse Osmosis, Multiple Effect Desalination, and Multistage Flash Distillation. Most designs are large and are not suitable for the relatively small energy output of a Bradford Combined Heat and ...
A zero maintenance hydroponic planter allows local food production in arid environments with minimal water consumption and eliminates detrimental runoff.
My device consists of
1) The reservoir
2) a fixed-position seed grid
3) a planter section
4) a reflective decal and
5) biomass base.
The reservoir provides 150% of the water required to grow the plant to fruition.
Initial setup requires filling both the reservoir and planter section with water/nutrient mixture then adding a layer of mulch/compost to the bottom.
This device uses non-circulating, hydroponic methodologies (http://www.ctahr.hawaii.edu/hawaii/downloads/Three_Non-circulating_Hydroponic_Methods_for_Growing_lettuce.pdf).
As such, the full ...
The light uses a revolutionary new solar collector design to concentrate sunlight from outside and then channels it into a home through the wall. The sunlight from outside is effectively directed into the house and then directed to either the roof, wall or workstation. This is ideal for using natural light to light up dark corners in a house without making a hole in the roof that could leak and which is also very expensive to install. The collectors unique design absorbs light from many angles without tracking the sun, so there are no moving parts that could break. ...
