Battery/electric vs Petrol

Instead of watching some YouTube videos, read some proper research.

I don't know if @Vespasian is right about a battery saw never going to make anything like a good 70cc felling saw. I agree that volume of petrol is a lot of energy to squeeze into a plastic case. One battery for the gob, then another for backcut etc.

But Eggs is right - Vespasian will never understand a complex subject like battery technology from Youtube presenters (self appointed experts who equip themselves with jargon to lend themselves an air of authority). The only way to know the cutting edge is to read the research. Unfortunately it takes a genuine interest in the subject to motivate oneself to read research.

I have spoken at length to the bloke that invented this.

He knows a bit about battery technology. I don't think he gleaned his knowledge through watching YouTube, but I'm sure Vesp will put me right.

the boffins predict the cost of batteries will keep dropping.

Cutting costs is not the same as increasing the energy density of a battery - I'm guessing this will be more of a challenge

The words " cowardice " and " scum " feature in most of your posts Vesp . I godda say you do spout some crap allot  of the time .

What about wood gas?
You can extract tars,oils,diesel,petrol and that's just the by products.
The gas(once cleaned) will burn readily in a petrol engine with only minor adjustments to the carb.
Most dried biomass will work.

If liquified it would be comparable to LPG.

Think about it, all that woodchip...

What about a water powered Hydrogen engine ? Have heard the petrochemical company's have bought up the patents  on this to shut it down till the oil runs out ....

Most, I'd say occasionally when justified..  my use of the word cowardice is a bit more nebulas as well..  though in essence it means the same..,   afraid to admit a truth for fear of its consequences..

Yeah....
That needed a 36kv arc to split the molecules.

During the WW2 over 500,000 vehicles on British roads used gasification, mainly using coal.

After paying £20 for 5 litres of aspen, I'm beginning to think there would be a market for wood petrol or liquified wood gas.

I'm sure the fella you spoke to is very well informed..   as I'm sure he believes battery technology will improve..  

 

But thinking it is not the same as seeing the evidence...
