I know, You guys are just baiting me. should I go for the hook?
You are certain that you are up to date on the state of today*s battery technology, are you?

Batteries best hope on climate change
Your article (Can technology stop climate change? July 7) failed to mention one of the most promising technologies for combating climate change: battery electric vehicles (BEVs).
The widespread adoption of BEVs would lead to improvements in air quality, particularly in urban areas, fewer greenhouse gas emissions and less noise pollution. BEVs can also be recharged using electricity from renewable sources, [ wind, hydro, solar], in which case their use produces no emissions at all.
BEVs have an important role to play in creating a sustainable, environmentally friendly transport system and uses technology that, unlike the hydrogen fuel cell, is available now and viable in the near future.

Hydrogen is not a source of energy. Elemental hydrogen does not occur naturally, it is an energy carrier like electricity, with which it shares certain environmental advantages when used as a fuel in transport systems.
Like electricity, hydrogen has to be made from primary energy sources. To make a significant impact on transport in the UK the choices seem to be to make it from 100 new nuclear plants, 100,000 wind turbines, biocrops replacing a substantial acreage of arable land, or to derive it from natural gas, coal or oil on a massive scale.
Before embarking on the huge investment required to store, distribute and dispense hydrogen to thousands of hydrogen filling stations, the merits of these and related options for its production need to be thoroughly evaluated in the light of the considerable research and development taking place in various countries.
The UK has much to offer on this and related work on fuel cells and carbon storage, but more needs to be done to co-ordinate it and to provide it with the backing it merits from government.
Before embarking on this huge investment indeed. Never!
Ask this question:
Is it logical to set up a huge and expensive hydrogen fuel network when the alternate energy source plug-in all ready exists in every building that uses a light bulb?
Would it be safer and more efficient to use hydrogen to produce power centrally or to have millions of hydrogen equipped cars on the highways requiring a whole new refueling system ?
Is it cheaper to use Hydro, wind, and solar energy to feed the grid for plug in battery electrical vehicles, or is it cheaper to pump crude out of the ground, truck it to the refinery, use energy to heat and crack the crude into various grades of oils and gasses, then truck it again to various outlets for sale?
Letter: These electric cars are no paralytics
Independent, The (London), Jul 5, 2005 by Ralph Lovesy
Sir: L K J Setright has a point when he refers to the on-board engine and gearbox of the hybrid car as a 'messy complication' ('Hybrids are not up to the job', 28 June). However, it is certainly an exaggeration to claim that 'carrying substantial storage batteries is what makes all electric vehicles paralytics' or that 'all present modes of storing electrical energy are inadequate'.
The latest battery electric vehicles (EVs) use relatively light lithium ion batteries, which provide a driving range and maximum speed that is more than adequate for average urban use. And with better acceleration than many petrol and diesel cars, EVs are anything but sluggish, as evidenced by electric sports cars such as the Fetish and T-Zero. Most importantly, EVs offer the opportunity to greatly reduce pollution, especially when they are charged with renewable electricity.
