Make the desktop architecture like laptop with regards to Power Electronics. I think now RAM’s consume lower power. So every Desktop can come with a Li-ion Backpack based on some standard. 10Ahr 12V Rechargeable Battery. The entire Motherboard works on the 12V DC supply that uses Float Charging from mains.
Power Electronics & Solar Energy
The supply to computer is always derived from battery, the battery being constantly replenished. The charger also supplies power to computer board over the battery itself. Many lighting/inverter systems use this. The SMPS now is only a intelligent charger. Other voltage levels with DC/DC converters from that 12V.
1 – A user can easily upgrade the 12 V bus, another 12 V battery with smart charger; gives a boost of backup time. Probably intelligent batteries can come with built in float chargers, so that they can they can be bussed to form a 12v Tiny power grid for home which includes solar cells.
2 – When just the backpack is used, power fails. Harddisk, Monitor etc. sent to standby, low power mode. CPU then goes to quiescent state. The RAM keeps all data intact but goes to a low power mode. Alternatively quickly write a RAM image on a Flash Layer Built over RAM.
This makes the PC Impervious to Power Supply or UPS or other problems. Moves the desktop system to a 12 V standard. Drives desktop PC development to more Power Efficient designs.
Switching Supplies and SMPS
Easy integration into automobiles, bus, etc which have DC grid. Remote areas where no power is there. This will ensure desktops have a role in the future.
The charger SMPS has 1A charging current for Battery and 3A max for Computer. Total 4A max. A SuperCap can be added parallel to the Battery for Extra Inertia.
When power fails, in few seconds the system goes to standby. No program need to be closed. When power is restored they system comes up with windows and programs in the same positions of the last frozen state.
When a UPS is used, the system does not go down at all. The UPS just consists of a 10A Charger and a 12V 20AHr Battery. If the house has a 24V DC bus which is battery supported too. Then this can be used. As 24V is being developed as a new standard for internal power distribution. EMerge Alliance. The PCs also can move to this manageable and safe standard for homes.

Solar Energy Uses in Homes: Solar Guide
“When electromagnetic waves strike an object they can cause various effects, such as excitation of the molecules, excitation and ejection of electrons, and oscillation of charge carriers in the object. As the result, a portion of the radiated photons can convert to heat, electricity or chemical energy”
Solar Grid-Intertie Inverter
An inverter is basically an electronic device that takes a DC input voltage and converts it to an AC output voltage. My design takes a 12V DC input from my solar panels (two 50w panels in parallel) and converts it 120V AC at 60Hz which is the power that most home appliances use. A grid-intertie inverter connects up to and external AC power system and matches it’s internal AC sinewave to the external AC sinewave to allow the inverter to feed power into the external system.
Presented in a Easy to understand, layman language. This Energy and Electrical Basics is a must for all who want to save power and lead a Green Lifestyle.

CIPCO Energy Library – Electrical Study
A class in basic electricity and how the electric utility industry generates and delivers power to customers. Designed primarily for use by utility field representatives who need to understand electrical principles. – Fundamentals of Electricity Covers the subject of motors from an explanation of how they work, to the advantages/disadvantages of adjustable speed drives, see Motors & Drives section.
Complete descriptive information on closed- and open-loop geothermal heat pump systems. Residential, multifamily and commercial applications are all covered. – Geothermal Heat Pump Systems
Converts normally wasted mechanical energy in the form of vibrations into usable electrical energy. It uses the piezoelectric effect to generate energy from Vibrations.
Piezoelectric Energy Harvester – V20w
Some sources are Machinery in Oil and Gas drilling to refining. Machines in Industry and Manufacturing. Wind, Tide, streams also can be harnesses with small fixtures, jigs or devices for vibration sensor arrays.
Applications – Wireless Sensors and small instruments need a way to recharge their lithium cells or even supercaps. Using solar and vibration harvesting, enough power can be derived to power efficient electronics. Recharge small computers and tablets.
