What Are the Burning Topics in Mechanical Eng?

Dear Sir I will definitely give plenty of advise on this but I need to know full details about you

Micro-machines were written about years ago, mostly just theory, based on using then current integrated circuit material technology (LSI). However, LSI technology did not allow these machines to be practical. Nano-technology is the new darling of the electronics industry, in creating smaller and denser VLSI chips.

Micro-machines are being rediscovered, with practical ideas, now that nano-technology has presented practical materials for implementation. One idea is an internal combustion engine fueled by butane (lighter fluid) connected to a micro-generator to create very tiny, re-fuelable, power packs, which could replace batteries in many cordless devices, including radios, flashlights, etc. Imagine, powering your portable devices when camping or during power outages, without worrying whether or not you had "fresh" alkaline batteries or if the rechargeable batteries were fully charged! Just "gas up" from your handy butane bottle and power up!

Similarly, many other mechanical or electro-mechanical devices may be scaled down to micro-size using nanotech materials and processes.

STL engineer is right, at the moment, ther is a lot of activity on nano-tech. based coating, and nano-tech. is very much at its infancy-the potential is cosmic!

At 15 cents per gallon 43% Hydrogen is available locally globally, tested at Va Tech with 98% combustion efficiency, reduces global warming, safely self contained, non hazardous, no VOC, non-explosive, clean, healthy, edible, reduces flyash, CO2 & CO, fully developed and shipping full factory capability that doubles annually, Interested? The Hydrogen source is commonly referenced worldwide as maize or corn maize. In the US just call it whole kernel shelled corn or horse corn. Do a google search for TennesseeCornStoves. Do a report on low cost effective corn energy.

Corn is 34% Hydrogen, sugars and starch. Sorry for the misprint. www.msnusers.com/cornstoves

is there any field(careers) relating to alternate energy sources aftre B.E engg(mech).
