U.S. military to implement an all-electric vehicle fleet by 2030????

DOOMBERG substack had HOW MANY PING PONG BALLS CAN YOU FIT IN A 747 – I Loved it.
It was used to test estimation skills apparently.What really caught my eye was "Department of Energy Secretary Jennifer Granholm said Wednesday that she supports efforts from the Biden administration to require the U.S. military to implement an all-electric vehicle fleet by 2030, telling lawmakers that she believes ‘we can get there.’"
Just for FUN
That put me in estimation mode myself with an M1A2 Abrams Main Battle Tank. They have a range of 251 miles or 403 km! Fuel Tanks is about 500 gallons 1885 litres.
How much battery would be required to move a M1A2 62-70 tonnes 400 km?
Using a very simple Power to weight per 100km gives me quirky estimate very short on reality perhaps 2000kWh-
Then you have to recharge them all!

The US may have “U.S. Army – 2,509 total, 750 M1A1SA, 1,605 M1A2 SEPv2, 154 M1A2 SEPv3 (some 3,700 more M1A1 and M1A2 in storage)”
The US Army will be using mobile Nuclear SMR if they have 2000+ thirsty EV battle tanks! S.M.R. nuclear power was invented for/by the US Navy of course for the famous USS Nautilus SSN-571.
.
The US military EV tanks and vehicle fleet cannot take power lines with them!

Love it! Calcs aren’t far off from my quick run of the numbers. I think they’d have to tow a battery pack trailer though as a 2,000kwh battery would take up approx 20 cubic metres and weigh 9.5 tonnes. [emoji16]

I did chuckle thinking about the weight going from 70 tonnes to 140 or more[thumbsupbig] I might have worked on the weight of my Flow batteries perhaps[bigrolf]

I said,single cab PROBABLY lighter,Dual Cab SIMILAR weight,not lighter.

Have a look at this,it's only one brand,there are many if you want to check them out.2WD are lighter again.

Kerb weight includes a full tank of fuel.

twiggy just fired his CEO and CFO because they did not share his objectives. One of the reasons its that he wanted to not claim the diesel subsidy.
I wonder if they have decided/recognised that the green hydrogen dream is just that.

The absolute lightest single cab one, with no fuel is 1800kg. But the time you fill it up with fuel and oil will be 1900kg. And no tray I assume. Is about the same weight as a five seater with full cabin EV. Right.

I think point made.

Hardly anyone buys those anyway. Most of them that I see are the dual cabs, starting at 2100kg. I don't think it's at all realistic to compare a 2 seater to a five seater. I mean my lotus is 700kg for a two seater. That makes EV's look really heavy.

PS if toyota are including fuel in kerb weight then that is a change because their weights used to be dry as. It's only Euro cars that include some fuel. The spec sheet just says "check it".

4x2 petrol Hilux single cab with Ali tray is 1490Kg.

Why are we comparing a car to a 4WD? Tesla is an around town car same as a Corolla etc so I would be making any comparison against other similar cars.

Even a dual cab at 2100KG,is not far off a 1900KG Tesla.

The Dual cab would be full of fuel,dunno about the Tesla[bigrolf]

This week, Tesla significantly expanded its Non-Tesla Supercharger Pilot program in Australia, which will improve access to reliable fast charging infrastructure for all EV users.
In the case of Australia, the first five Supercharging stations (all in New South Wales) were included in the Non-Tesla Supercharger Pilot in February. As of today, we counted roughly 30 locations, which appears to be more than half of all Supercharging sites in the country.

That is eally noice of letric pedo giy toss..... I have Sat slowly beside many empty SUperduper chargers so many time on my Chemo express runs I honestly could never ever use one now. Happily I do not need to see them at all now.

Perhaps my last Chemo express EV drive will be next week. very happily stopping at a non Eletric Jesus charging place.

Noting the Eletric Jesus car battery failed and was replaced very recently. That one has very few KM traveled on its clock. [bigrolf]

This one could be in Grumpy OLD buggers perhaps.

The map suggest I could. NOt a cent of my money will go that way[thumbsupbig]
